Coastal Project Innovation: Lida Group's Corrosion-Resistant Prefab Building Systems Protect Temporary Sandwich House Dwellings

Coastal Project Innovation: Lida Group’s Corrosion-Resistant Prefab Building Systems Protect Temporary Sandwich House Dwellings

1. Introduction

Coastal regions are hubs of economic activity, supporting industries ranging from tourism and fisheries to offshore energy and port operations. These areas also face unique challenges, however, as they are exposed to one of the most destructive forces in nature: the corrosive power of saltwater, salt-laden air, and harsh coastal weather. For organizations undertaking temporary projects in coastal zones—such as building beachfront resorts, supporting offshore wind farms, housing construction crews for port expansions, or providing emergency shelters after coastal storms—the need for durable, corrosion-resistant temporary housing is critical.

Traditional temporary structures, often made from standard steel, wood, or concrete, struggle to withstand coastal conditions. Saltwater and salt air accelerate rust and degradation, leading to structural damage, safety risks, and frequent, costly repairs. Wood rots, unprotected steel corrodes, and concrete spalls (a process where salt penetrates the surface and causes internal cracking), all of which shorten the lifespan of temporary buildings and compromise the comfort and safety of occupants.

Lida Group, a global leader in prefabricated (prefab) building solutions, has addressed this gap with its corrosion-resistant prefab building systems, specifically engineered to protect temporary sandwich house dwellings in coastal environments. These systems combine innovative materials, precision manufacturing, and coastal-specific design features to create structures that are not only durable against corrosion but also fast to deploy, energy-efficient, and adaptable to diverse coastal project needs.

This article explores the unique challenges of coastal temporary housing, delves into the technical innovations behind Lida Group’s corrosion-resistant systems, examines real-world applications of these solutions, and highlights why they have become the preferred choice for organizations operating in coastal regions. By the end, it will be clear how Lida Group’s innovation is redefining temporary housing in coastal areas—turning a once-high-maintenance, high-risk necessity into a reliable, long-lasting asset.

2. The Unique Challenges of Coastal Temporary Housing

Before examining Lida Group’s solutions, it is essential to understand the specific threats that coastal environments pose to temporary buildings. These challenges go beyond typical weather concerns; they are rooted in the chemical and physical impact of salt, moisture, and extreme weather—all of which work together to break down traditional building materials.

2.1 Saltwater and Salt-Laden Air: The Primary Corrosion Threat

The most significant challenge in coastal areas is salt-induced corrosion. Saltwater (sodium chloride) and salt-laden air (aerosols carried by coastal winds) are highly conductive and reactive, accelerating the oxidation of metals and the degradation of other materials. Here’s how this affects common building components:

Steel and Metal Components: Unprotected steel begins to rust (iron oxide) within weeks of exposure to salt air. Rust weakens the metal, causing structural frames to bend, fasteners to fail, and exterior cladding to peel. Even galvanized steel—coated with a thin layer of zinc—can corrode over time if the coating is scratched or damaged, as saltwater will penetrate the zinc and attack the steel beneath.

Wood: Saltwater and high humidity cause wood to absorb moisture, leading to rot, mold, and infestation by wood-boring insects. Salt also deposits crystals within the wood, which expand and contract with temperature changes, accelerating cracking and splitting.

Concrete: Salt ions (chlorides) penetrate concrete pores, reacting with the steel reinforcement bars (rebar) inside. This reaction produces rust, which expands and pushes against the concrete, causing it to crack, chip, and spall. Spalled concrete not only looks unsightly but also exposes more rebar to corrosion, creating a destructive cycle.

Electrical and Plumbing Systems: Saltwater is highly conductive, increasing the risk of electrical shorts and failures in unprotected wiring. Plumbing pipes made from standard metals (e.g., copper) corrode quickly, leading to leaks and contaminated water supplies.

For temporary buildings, this corrosion is particularly problematic. Unlike permanent structures, which may undergo regular maintenance or have thicker, more protective materials, temporary housing is often designed for short-term use—but in coastal areas, “short-term” can turn into frequent replacements if corrosion is not addressed.

2.2 Extreme Coastal Weather: Wind, Rain, and Storms

Coastal regions are prone to extreme weather events that compound corrosion damage:

High Winds and Hurricanes/Typhoons: Strong winds can tear off exterior cladding, break windows, and damage roof structures—exposing the building’s interior to saltwater and air. Even moderate winds (25–30 km/h) carry salt aerosols further inland, expanding the corrosion zone beyond immediate coastal areas.

Heavy Rain and Storm Surges: Rainwater mixes with salt, creating a highly corrosive solution that seeps into cracks in the building’s exterior. Storm surges—rising seawater pushed ashore by storms—submerge lower parts of buildings in saltwater, causing catastrophic damage to foundations, floors, and lower walls.

UV Radiation: Intense coastal sunlight accelerates the degradation of paint, plastics, and wood finishes. Faded, cracked paint exposes underlying materials to salt and moisture, worsening corrosion.

2.3 Humidity and Mold Growth

Coastal areas have high humidity levels (often 70–90% year-round), which create ideal conditions for mold and mildew growth. Mold not only damages interior finishes (e.g., drywall, furniture) but also poses health risks to occupants, including respiratory issues and allergies. Traditional temporary buildings often have poor ventilation, trapping moisture inside and exacerbating mold problems.

2.4 Environmental Regulations and Aesthetics

Many coastal regions have strict environmental regulations to protect fragile ecosystems (e.g., mangroves, coral reefs, or dunes). Permanent construction may be prohibited or heavily restricted, making temporary housing the only viable option. Additionally, coastal projects—such as tourism developments or high-profile events—require temporary buildings that are aesthetically pleasing, as they contribute to the overall appeal of the area. Traditional temporary structures, with their utilitarian design and rapid deterioration, often fail to meet these aesthetic standards.

These challenges collectively create a demand for temporary housing that is:

Corrosion-resistant: Able to withstand saltwater, salt air, and humidity.

Weatherproof: Protected against high winds, storms, and UV radiation.

Moisture-controlled: Well-ventilated to prevent mold growth.

Fast to deploy: Aligned with the tight timelines of coastal projects.

Aesthetically pleasing: Compliant with local regulations and project goals.

Lida Group’s corrosion-resistant prefab building systems are engineered to meet all these requirements—redefining what temporary coastal housing can be.

3. Lida Group’s Corrosion-Resistant Prefab Building Systems: Technical Innovations

At the core of Lida Group’s solution for coastal temporary housing is its corrosion-resistant prefab building system, a integrated set of components designed to work together to block salt, moisture, and weather damage. The system revolves around three key innovations: premium corrosion-resistant materials, coastal-specific sandwich panel designs, and weatherproof structural engineering. Each element is rigorously tested to ensure it performs in the harshest coastal conditions.

3.1 Premium Corrosion-Resistant Materials: The Foundation of Durability

Lida Group selects materials specifically for their ability to resist salt-induced corrosion, replacing traditional steel, wood, and concrete with higher-performance alternatives. Every component—from structural frames to fasteners to interior finishes—is chosen for its coastal durability.

3.1.1 Structural Frames: Marine-Grade Aluminum Alloy and Heavy-Duty Galvanized Steel

The structural frame is the backbone of any building, and in coastal areas, it must be impervious to corrosion. Lida Group offers two frame options, depending on the project’s needs:

Marine-Grade Aluminum Alloy (5052 and 6061 Series): For projects requiring lightweight mobility (e.g., temporary event spaces or emergency shelters), Lida Group uses marine-grade aluminum alloy. This alloy contains magnesium and chromium, which form a protective oxide layer on the surface—preventing saltwater and air from penetrating the metal. Unlike steel, aluminum does not rust; instead, it forms a stable, non-flaking oxide layer that self-repairs if scratched. Marine-grade aluminum is also 30% lighter than steel, making it easier to transport and install in remote coastal areas. It has a tensile strength of up to 310 MPa (megapascals), ensuring structural stability even in high winds.

Heavy-Duty Hot-Dip Galvanized Steel (G90 Coating): For projects requiring maximum load-bearing capacity (e.g., worker accommodations for offshore wind farms or multi-story temporary resorts), Lida Group uses hot-dip galvanized steel with a G90 coating. Hot-dip galvanization involves dipping steel into a bath of molten zinc, creating a thick (90 grams per square meter), uniform coating that acts as a barrier against salt and moisture. The G90 coating is 50% thicker than standard galvanized coatings, extending the steel’s lifespan in coastal areas to 20–25 years (compared to 5–10 years for standard galvanized steel). The steel is also treated with a passivation layer—a chemical coating that further enhances corrosion resistance by preventing zinc oxide from forming on the surface.

Both frame materials are tested in Lida Group’s in-house corrosion laboratory, where they are exposed to salt spray (per ASTM B117 standards) for 1,000 hours—equivalent to 5–7 years of coastal exposure. After testing, the frames show no signs of corrosion, ensuring they meet the highest durability standards.

3.1.2 Exterior Cladding: Fiber-Reinforced Polymer (FRP) and Aluminum Composite Panels (ACPs)

The exterior cladding is the first line of defense against salt air and weather, so Lida Group uses materials that are both corrosion-resistant and aesthetically versatile:

Fiber-Reinforced Polymer (FRP): FRP is a composite material made from glass fibers embedded in a polyester resin matrix. It is completely impervious to saltwater, salt air, and UV radiation—making it ideal for coastal exteriors. FRP is also lightweight (50% lighter than steel), impact-resistant, and available in a range of textures and colors (e.g., wood grain, stone, or solid hues). Unlike wood, it does not rot or fade; unlike steel, it does not rust. FRP cladding is also low-maintenance, requiring only occasional cleaning with fresh water to remove salt deposits.

Aluminum Composite Panels (ACPs): For projects requiring a sleek, modern look (e.g., luxury temporary resorts or VIP event spaces), Lida Group uses ACPs with a fluoropolymer (PVDF) coating. ACPs consist of two thin aluminum skins bonded to a polyethylene core. The aluminum skins are coated with PVDF—a high-performance resin that is resistant to salt, UV radiation, and fading. PVDF coatings have a lifespan of 15–20 years in coastal areas, maintaining their color and gloss even after years of exposure. The polyethylene core is lightweight and moisture-resistant, further enhancing the panel’s durability.

Both FRP and ACP cladding are pre-finished in the factory, eliminating the need for on-site painting (which often peels in coastal areas). They are also designed to interlock with weathertight seals, preventing saltwater from seeping between panels.

3.1.3 Fasteners and Hardware: Stainless Steel (316 Grade)

Even the smallest components—such as screws, bolts, and hinges—can become points of failure if they corrode. Lida Group uses only 316-grade stainless steel for all fasteners and hardware. 316-grade stainless steel contains molybdenum, which gives it superior corrosion resistance compared to standard 304-grade stainless steel (often used in non-coastal applications). It is resistant to saltwater, salt air, and even acidic conditions (e.g., coastal areas with high pollution), making it the gold standard for coastal hardware. All fasteners are also coated with a dry lubricant to prevent seizing (a common issue when metal components corrode and stick together).

3.1.4 Interior Finishes: Moisture-Resistant Materials

Interior finishes must resist mold and moisture, so Lida Group uses materials that are easy to clean and impervious to humidity:

Flooring: Luxury vinyl plank (LVP) or ceramic tile. LVP is waterproof, scratch-resistant, and mimics the look of wood or stone. Ceramic tile is also waterproof and easy to clean, with a glaze that prevents mold growth.

Walls: Moisture-resistant drywall or FRP panels. Moisture-resistant drywall has a green paper facing that repels water, while FRP wall panels are completely waterproof and easy to wipe down.

Ceilings: Vinyl or aluminum ceiling tiles. Both materials are moisture-resistant and prevent condensation buildup, which can lead to mold.

3.2 Coastal-Specific Sandwich Panel Designs: Insulation and Corrosion Protection in One

Lida Group’s temporary sandwich house dwellings are built using coastal-specific sandwich panels—the heart of the system. These panels integrate structural support, insulation, and corrosion resistance into a single, prefabricated component, streamlining production and installation while ensuring durability.

3.2.1 Panel Composition: Corrosion-Resistant Skins and Moisture-Barrier Cores

Lida Group’s coastal sandwich panels have three layers:

Outer Skin: Made from FRP or ACP (as described in Section 3.1.2), providing corrosion resistance and weather protection.

Core: A high-density insulation material with a moisture-barrier coating. Lida Group offers two core options:

- Closed-Cell Polyisocyanurate (PIR) Foam: PIR foam has excellent thermal insulation (R-value of 5.8 per inch) and a closed-cell structure that prevents moisture absorption. It is also fire-retardant (meeting ASTM E84 Class A standards) and resistant to saltwater. The core is coated with a polyethylene moisture barrier to further block water vapor.

- Extruded Polystyrene (XPS) Foam: For projects in extremely humid coastal areas (e.g., tropical beachfronts), Lida Group uses XPS foam. XPS has a closed-cell structure that is 100% waterproof, even if the panel is damaged. It also has a high R-value (5.0 per inch) and is resistant to mold and mildew.

Inner Skin: Made from aluminum or FRP, providing a smooth, moisture-resistant interior surface that is easy to clean.

The layers are bonded together using a high-strength, moisture-resistant adhesive that is tested to withstand coastal temperatures (ranging from -5°C to 45°C) without delaminating.

3.2.2 Edge Seals and Joints: Weathertight Protection

A critical weakness of many sandwich panels is the edges, where saltwater and moisture can seep in. Lida Group addresses this with precision-engineered edge seals and tongue-and-groove joints:

Edge Seals: Each panel’s edges are sealed with EPDM rubber gaskets— a durable, weather-resistant material that is resistant to salt, UV radiation, and temperature changes. The gaskets compress when the panels are joined, creating a tight, waterproof seal.

Tongue-and-Groove Joints: The panels feature a tongue-and-groove design that locks them together, preventing lateral movement (caused by high winds) and creating a continuous barrier against saltwater. The joints are also filled with a marine-grade silicone sealant that adheres to both the panels and the EPDM gaskets, further enhancing weather resistance.

These features ensure that the panels act as a single, seamless barrier against salt and moisture—no gaps, no leaks, no corrosion.

3.3 Weatherproof Structural Engineering: Withstanding Coastal Storms

In addition to corrosion resistance, Lida Group’s prefab systems are engineered to withstand extreme coastal weather, including high winds, storm surges, and heavy rain.

3.3.1 Wind Load Resistance: Aerodynamic Design and Reinforced Frames

Lida Group’s temporary houses are designed to withstand wind speeds of up to 180 km/h (equivalent to a Category 3 hurricane), based on international standards (e.g., ASCE 7-16 for wind loads). Key design features include:

Aerodynamic Roofs: The roofs are sloped at a 30–45 degree angle to reduce wind resistance, preventing lift (a common cause of roof failure in storms). The roof edges are also reinforced with wind deflectors to minimize turbulence.

Reinforced Frames: The structural frames are engineered with additional bracing (e.g., diagonal steel or aluminum members) to distribute wind loads evenly across the building. The frames are also anchored to the ground using galvanized steel anchors or concrete footings, preventing the building from being lifted or shifted by high winds.

Impact-Resistant Windows and Doors: Windows and doors are made from tempered glass with aluminum frames (316-grade stainless steel hardware). The glass is coated with a UV-resistant film to prevent shattering, and the frames are sealed with EPDM gaskets to prevent water intrusion.

3.3.2 Storm Surge Protection: Elevated Foundations and Water-Resistant Lower Walls

For projects in areas prone to storm surges (e.g., low-lying coastal regions), Lida Group offers elevated foundation systems:

Steel Piers or Concrete Blocks: The houses are elevated 1–2 meters above the ground using steel piers (marine-grade aluminum) or concrete blocks (coated with a waterproof sealer). This prevents storm surges from submerging the lower walls and floors.

Water-Resistant Lower Walls: The lower portion of the walls (up to 1.5 meters) is clad in FRP or ACP, which are completely waterproof. This ensures that even if water reaches the lower walls, it does not cause damage.

3.3.3 Ventilation and Moisture Control: Preventing Mold Growth

To address high coastal humidity, Lida Group’s houses are equipped with mechanical ventilation systems and moisture barriers:

Heat Recovery Ventilators (HRVs): HRVs exchange stale, moist indoor air with fresh, dry outdoor air while retaining heat (in cool climates) or cooling (in warm climates). This reduces indoor humidity levels to 40–50%, preventing mold growth.

Vapor Barriers: A polyethylene vapor barrier is installed between the insulation core and the inner skin of the sandwich panels, preventing moisture from seeping into the insulation and causing mold or mildew.

Dehumidifiers: For extremely humid areas, Lida Group can integrate energy-efficient dehumidifiers into the HVAC system, further reducing indoor moisture.

4. Lida Group’s Temporary Sandwich House Dwellings: Coastal-Specific Designs for Diverse Projects

Lida Group’s corrosion-resistant prefab system is not a one-size-fits-all solution—it is adaptable to a wide range of coastal projects, from luxury tourism developments to industrial worker accommodations. The company offers three primary lines of temporary sandwich house dwellings, each tailored to specific project needs while retaining the core corrosion-resistant features.

4.1 Coastal Tourism and Glamping: Luxury That Withstands the Sea

The global coastal tourism market demands temporary accommodations that are both luxurious and durable—structures that blend with the natural environment while resisting salt and weather. Lida Group’s Coastal Glamping Series is designed for this market, offering units that feel like high-end vacation homes but are temporary and mobile.

Key Features of the Coastal Glamping Series

Aesthetic Design: Exterior cladding uses FRP with wood grain or stone textures, blending with beachfront or coastal landscapes. Large, floor-to-ceiling windows (tempered glass with UV protection) provide panoramic ocean views, while sliding glass doors open to private decks (made from marine-grade composite wood, which is resistant to salt and rot).

Interior Luxury: Interiors feature high-end finishes, including LVP flooring (mimicking hardwood), quartz countertops, and premium furniture (waterproof outdoor-grade sofas and beds). Bathrooms include rain showers with stainless steel fixtures and eco-friendly toiletries.

Energy Efficiency: The PIR foam sandwich panels provide excellent insulation, reducing energy use for air conditioning (critical in warm coastal climates). Many units are equipped with solar panels on the roof (integrated into the panel design) to power lighting and small appliances, reducing reliance on grid electricity.

Mobility: The units are modular and lightweight (thanks to marine-grade aluminum frames), making them easy to transport to remote coastal sites (e.g., private islands or undeveloped beachfronts). They require minimal site preparation—just a level surface and access to water and electricity.

Real-World Application: Tropical Beachfront Glamping Resort

A tourism developer in Southeast Asia partnered with Lida Group to create a 30-unit glamping resort on a remote beachfront. The developer needed units that could withstand monsoon rains, salt air, and high humidity, while also offering guests luxury comfort. Lida Group’s solution included:

FRP cladding with a teak wood texture to blend with the surrounding palm trees.

PIR foam sandwich panels for insulation against the tropical heat.

Elevated steel piers to protect against storm surges during monsoon season.

HRVs and dehumidifiers to maintain indoor comfort in high humidity.

The units were transported by boat to the island and assembled in 14 days. After two years of operation, the resort reported no signs of corrosion or mold, and guest satisfaction scores were 20% higher than at the developer’s previous resort (which used traditional wooden cabins). The units also required minimal maintenance—just monthly cleaning of the exterior to remove salt deposits.

4.2 Offshore Energy and Industrial Projects: Durable Accommodations for Workers

Offshore energy projects (e.g., wind farms, oil rigs) and coastal industrial projects (e.g., port expansions, desalination plants) require temporary housing for hundreds of workers. These accommodations must be durable, safe, and comfortable—even in the harshest offshore conditions. Lida Group’s Industrial Coastal Series is designed for this market, focusing on durability, functionality, and scalability.

Key Features of the Industrial Coastal Series

Heavy-Duty Construction: Structural frames use hot-dip galvanized steel (G90 coating) for maximum load-bearing capacity and corrosion resistance. Exterior cladding uses ACPs with PVDF coatings, which are resistant to salt, UV radiation, and impact (from tools or equipment).

Functional Layouts: Units are available in single, double, or quadruple occupancy layouts, with each worker having a private bed (with a waterproof mattress), storage space, and personal lighting. Communal areas include dining halls, kitchens (with stainless steel appliances), and recreation rooms (with moisture-resistant furniture).

Safety Features: The units meet international safety standards for offshore and industrial sites, including fire resistance (FRP cladding and PIR foam cores are fire-retardant), emergency exits, and smoke detectors. Electrical systems are rated for wet locations (IP67) to prevent shorts from saltwater.

Scalability: The modular design allows companies to add or remove units as the workforce size changes. Units can also be connected to form larger structures (e.g., a 100-bed dormitory or a multi-room office complex).

Real-World Application: Offshore Wind Farm Worker Accommodations

A renewable energy company operating in the North Sea needed accommodations for 200 workers supporting the construction of an offshore wind farm. The company required units that could withstand saltwater spray, high winds (up to 150 km/h), and sub-zero temperatures in winter. Lida Group’s solution included:

Hot-dip galvanized steel frames with additional wind bracing.

XPS foam sandwich panels for insulation against cold temperatures.

ACP cladding with a PVDF coating in the company’s brand color (blue).

Heated floors and HRVs to maintain indoor temperatures above 20°C in winter.

The units were transported to the onshore construction site via truck and assembled in 21 days. After 18 months of operation, the units showed no signs of corrosion, and worker turnover was reduced by 15% (compared to the company’s previous accommodations, which used standard steel containers). The company also reported lower maintenance costs—just \(500 per unit per year, compared to \)2,000 per unit per year for the containers.

4.3 Emergency Response and Disaster Relief: Rapid, Resilient Shelters

Coastal regions are prone to natural disasters, such as hurricanes, typhoons, and tsunamis, which displace thousands of people each year. NGOs and governments need temporary shelters that are fast to deploy, safe, and durable enough to house displaced populations for 6–12 months. Lida Group’s Coastal Emergency Series is designed for this critical market.

Key Features of the Coastal Emergency Series

Rapid Deployment: Units are prefabricated as complete modules (rather than panels) and can be shipped via truck, boat, or plane. They can be set up by a small team (4–6 workers) in 4–6 hours, with no specialized tools required.

Durability: Frames use marine-grade aluminum alloy, which is lightweight but strong enough to withstand post-disaster weather (e.g., strong winds, heavy rain). Exterior cladding uses FRP, which is impact-resistant and waterproof.

Basic Comfort: Units are designed to house 8–10 people, with bunk beds, a small kitchenette (with a propane stove and sink), and a bathroom (with a composting toilet and shower). The sandwich panels provide insulation, and ventilation systems prevent mold growth.

Cost-Effectiveness: The units are affordable to produce and transport, making them accessible to NGOs with limited budgets. They are also reusable—after a disaster, they can be disassembled and stored for future use.

Real-World Application: Post-Hurricane Shelter in the Caribbean

After a Category 4 hurricane struck a Caribbean island, an international NGO partnered with Lida Group to deploy 100 emergency shelters. The NGO needed shelters that could be delivered quickly, withstand residual storms, and protect families from salt air and humidity. Lida Group’s solution included:

Marine-grade aluminum frames for lightweight transport (shipped via military cargo plane).

FRP cladding and XPS foam cores for waterproofing and insulation.

Elevated concrete block foundations to protect against flooding.

Solar-powered lighting and fans to provide basic comfort (grid electricity was unavailable).

The shelters were delivered within 72 hours of the hurricane and set up in 5 days. They housed 800 people for 10 months while permanent housing was rebuilt. During that time, the shelters withstood two additional tropical storms and showed no signs of corrosion or mold. The NGO praised the shelters for their durability and ease of use, noting that they were “far more comfortable and resilient than traditional tents.”

5. Quality Control and Compliance: Ensuring Coastal Durability

Lida Group’s commitment to corrosion resistance is not just a design claim—it is backed by rigorous quality control measures and compliance with international standards. The company understands that organizations operating in coastal areas rely on its buildings to be safe, durable, and consistent, so it has implemented a comprehensive quality management system that covers every stage of production and installation.

5.1 Material Testing: Proving Corrosion Resistance

Before any material is used in production, it undergoes extensive testing in Lida Group’s in-house corrosion laboratory, which is certified to conduct tests according to international standards (e.g., ASTM, ISO, and DIN). Key tests include:

Salt Spray Test (ASTM B117): Materials are exposed to a continuous spray of saltwater (5% sodium chloride solution) at 35°C for up to 1,000 hours. This simulates 5–7 years of coastal exposure. After testing, materials are inspected for rust, peeling, or degradation. Only materials that show no signs of corrosion pass.

UV Resistance Test (ASTM G154): Exterior cladding and coatings are exposed to intense UV radiation (simulating coastal sunlight) for 500 hours. This tests for fading, cracking, or peeling. Materials must retain at least 80% of their original color and gloss to pass.

Moisture Absorption Test (ASTM C272): Insulation cores are submerged in water for 24 hours to test their moisture resistance. Materials that absorb more than 1% of their weight in water are rejected.

Wind Load Test (ASTM E330): Structural frames and panels are tested in a wind tunnel to ensure they can withstand wind speeds of up to 180 km/h. Frames that bend or fail are redesigned.

All test results are documented and made available to clients, providing transparency and confidence in the materials’ performance.

5.2 Factory Production Control: Ensuring Consistency

Lida Group’s factories use automated production lines and digital quality control systems to ensure every component meets specifications. Key measures include:

Precision Cutting and Bonding: Computer-controlled machines cut materials to exact dimensions (within ±1mm), ensuring panels and frames fit together perfectly. Automated bonding machines apply adhesive evenly and under controlled pressure, preventing delamination.

In-Process Inspections: Quality control inspectors check each component at every stage of production (e.g., after cutting, after bonding, after edge sealing). Inspectors use digital tools (e.g., thickness gauges, moisture meters) to verify material properties. Any component that fails inspection is repaired or discarded.

Serial Number Tracking: Each panel, frame, and fastener is assigned a unique serial number, allowing Lida Group to track its production history (e.g., materials used, testing results, production date). This makes it easy to identify and address any issues that may arise.

5.3 Compliance with International Standards

Lida Group’s coastal prefab systems meet or exceed a range of international standards, ensuring they are safe and legal to use in global markets. Key standards include:

ISO 9001: Quality management system certification, ensuring consistent production and customer satisfaction.

ISO 14001: Environmental management system certification, demonstrating the company’s commitment to sustainable production (e.g., using recyclable materials, reducing waste).

ASTM International: Compliance with ASTM standards for corrosion resistance (ASTM B117), wind load resistance (ASTM E330), and fire safety (ASTM E84).

Local Coastal Regulations: Lida Group works closely with local authorities to ensure its buildings comply with regional standards, such as hurricane resistance codes in the Caribbean or typhoon codes in Southeast Asia.

This compliance gives clients confidence that Lida Group’s buildings are not just durable—they are also safe and legal to use in their target coastal regions.

6. Sustainability: Corrosion Resistance Meets Eco-Friendliness

In addition to durability, modern coastal projects require solutions that are environmentally friendly. Lida Group’s corrosion-resistant prefab systems are designed with sustainability in mind, offering a range of eco-friendly benefits that align with global climate goals and local environmental regulations.

6.1 Reduced Waste and Energy Use During Production

Traditional construction in coastal areas generates significant waste, as materials are cut and shaped on-site and excess materials are discarded. Lida Group’s off-site prefabrication minimizes waste in several ways:

Precision Manufacturing: Automated cutting machines reduce material scrap by up to 90% compared to on-site construction. Any scrap material (e.g., aluminum, FRP, foam) is recycled, rather than sent to landfills.

Energy-Efficient Factories: Lida Group’s factories use solar panels and energy-efficient lighting, heating, and cooling systems, reducing the carbon footprint of production. The company also uses electric vehicles for material transport within factories, further lowering emissions.

6.2 Energy Efficiency in Use

Lida Group’s sandwich panels and insulation materials reduce energy use for heating and cooling, lowering both carbon emissions and operating costs:

Superior Insulation: PIR and XPS foam cores have high R-values, reducing the need for air conditioning in summer and heating in winter. A coastal glamping unit from Lida Group uses 40–60% less energy for HVAC than a traditional temporary structure.

Renewable Energy Integration: The panels are designed to accommodate solar panels, wind turbines, and other renewable energy systems. Many clients choose to power their units with solar energy, reducing reliance on fossil fuels.

6.3 Recyclability and Reusability

Lida Group’s prefab systems are fully recyclable and reusable, aligning with circular economy principles:

Reusability: The modular design allows buildings to be disassembled and relocated to new coastal projects. For example, a set of worker accommodations used for a port expansion can be moved to an offshore wind farm project once the port is complete.

Recyclability: When the buildings reach the end of their lifespan (20–25 years in coastal areas), materials such as aluminum, stainless steel, and FRP can be recycled into new products. The foam cores can be recycled into insulation materials or converted into energy through waste-to-energy facilities.

This recyclability and reusability reduce the environmental impact of temporary coastal housing, making Lida Group’s systems a sustainable choice for eco-conscious clients.
