Innovative Metal Frame Construction by Lida Group Creates Durable High Quality House

The global construction industry is continuously pursuing the balance of structural durability, construction quality, cost efficiency and green sustainability. Building frame systems serve as the fundamental skeleton that determines the overall performance, service life and safety level of all buildings. For decades, traditional construction relies heavily on wooden frames, ordinary welded steel frames and concrete load-bearing structures. These conventional frame construction methods have long-standing inherent drawbacks, including poor dimensional stability, weak weather resistance, vulnerable structural deformation, high maintenance consumption and low reusability. Wooden frames are prone to termite erosion, mildew decay and flammable risks. Welded steel frames suffer from welding stress deformation, joint rusting and inconsistent assembly quality.

1. Limitations of Traditional Building Frame Construction

Traditional building frame construction technologies cannot meet the refined and durable quality requirements of modern construction, restricting the overall quality improvement and sustainable development of buildings. Wooden, welded steel and concrete frames, as the three mainstream traditional frame forms, all have obvious performance defects and construction drawbacks.

Wooden frame construction features low material cost and lightweight advantages, but its natural material properties determine fatal durability defects. Wood is highly susceptible to moisture absorption, mildew growth, termite and microbial erosion in outdoor humid environments. It is also flammable and prone to deformation and cracking under extreme temperature and humidity changes. Most wooden frame buildings have a service life of less than five years in outdoor open environments and require regular anti-corrosion, insect-proof and fire-proof maintenance throughout the operation cycle, resulting in high comprehensive maintenance costs. In addition, wooden frames rely on natural forest resources, causing resource consumption and ecological pressure, and cannot be recycled and reused after aging, failing to adapt to global green construction trends.

Ordinary welded steel frame construction improves structural strength compared with wooden frames, yet its backward welding process brings multiple quality hidden dangers. On-site manual welding is easily affected by weather, temperature and worker operation proficiency, leading to uneven welding quality, incomplete fusion, welding cracks and residual welding stress. Long-term outdoor exposure will cause rust and corrosion at welding joints, resulting in structural loosening and deformation. Moreover, welded frames form fixed integrated structures that cannot be disassembled and relocated. After project completion, the frames can only be scrapped, resulting in serious resource waste. The rigid welded structure also lacks flexible deformation capacity, with poor seismic and impact resistance in extreme natural disaster scenarios.

Concrete frame structures have high rigidity and compressive strength but suffer from heavy self-weight, poor seismic toughness and uncontrollable construction quality. On-site pouring and curing require long construction cycles and are easily disturbed by external environmental factors, causing hollowing, cracking and dimensional deviation. The heavy frame structure puts forward high requirements for foundation bearing capacity, increasing foundation construction cost and cycle. Meanwhile, concrete structures cannot be disassembled and reused, generating massive construction waste after demolition, with low comprehensive economic and environmental benefits. In general, the universal defects of traditional frame construction urgently require innovative metal frame technology to achieve comprehensive quality and durability upgrading of modern buildings.

2. Core Innovation Principles of Lida Group’s Metal Frame Construction Technology

Lida Group’s innovative metal frame construction technology takes “durability, high precision, stability and flexibility” as the core design concept. Through systematic innovation in material selection, structural design, processing technology and assembly mode, it completely solves the quality and performance defects of traditional frame structures, laying a solid technical foundation for manufacturing high-quality durable buildings.

2.1 High-Strength Customized Metal Material Formula

Material performance is the fundamental guarantee of frame durability. Lida Group selects exclusive low-alloy high-strength galvanized metal materials for frame production. Compared with ordinary steel and wood, this customized metal material has an ultra-high strength-to-weight ratio, which is 25 times higher than traditional concrete materials. It ensures excellent tensile strength, compressive resistance and structural toughness while maintaining lightweight characteristics. The lightweight frame effectively reduces the overall self-weight of the building, lowers foundation bearing requirements, adapts to various complex terrains, and avoids structural settlement and cracking caused by insufficient foundation strength.

In terms of material stability, the customized metal material is completely impervious to termite erosion, microbial decay and mold growth, overcoming the natural defects of wooden frames. The uniform and stable internal metal texture avoids brittle fracture problems of ordinary low-quality steel. All raw metal materials undergo strict factory sampling inspection and performance testing to ensure consistent thickness, stable mechanical properties and zero quality defects, fundamentally guaranteeing the basic durability and safety of building frames.

2.2 Multi-Layer Composite Anti-Corrosion and Anti-Aging Technology

Outdoor building frames face long-term erosion from rainwater, humid air, coastal salt spray, ultraviolet radiation and desert sandstorms, making anti-corrosion and anti-aging performance the key to structural durability. Different from the single galvanization treatment of ordinary steel frames, Lida Group’s innovative metal frames adopt dual protection technology of hot-dip galvanizing and multi-layer weather-resistant polymer coating.

The hot-dip galvanizing process forms a dense and uniform zinc protective layer on the metal surface, completely isolating the metal matrix from air and moisture to prevent oxidation and electrochemical corrosion. The outer polymer weather-resistant coating further enhances ultraviolet resistance, salt spray corrosion resistance, scratch resistance and anti-fading performance. This multi-layer composite protection system enables the metal frame to maintain stable structural performance in extreme environments ranging from alpine low temperature, coastal high humidity to desert high temperature, effectively avoiding rust, aging and structural loosening. Verified by long-term outdoor simulation tests, the anti-corrosion and anti-aging system ensures the metal frame’s stable service life exceeds 25 years.

2.3 Digital Precision Factory Fabrication

Quality inconsistency is a prominent pain point of traditional on-site construction. Lida Group’s metal frame components are all processed in fully automated digital factories, abandoning backward manual on-site production modes. Supported by CNC numerical control equipment and finite element simulation analysis technology, all metal frame beams, columns and connecting accessories complete precision cutting, punching and forming in standardized production lines.

The whole production process realizes full digital control, with component dimensional accuracy controlled within ±2 millimeters. Before leaving the factory, every batch of metal frames undergoes professional structural stress testing, bearing capacity verification and assembly simulation testing to ensure stable mechanical performance and accurate connection matching. Unified factory standardized production eliminates quality deviation caused by manual operation errors and environmental interference, ensuring consistent and reliable structural quality of each building frame and greatly improving the overall finished quality of buildings.

2.4 Modular Bolted Quick-Assembly Structure

Lida Group’s most core innovative breakthrough is abandoning traditional on-site welding construction and adopting standardized bolted modular assembly technology. All metal frame components reserve precise unified connecting holes during factory processing without on-site cutting, welding and painting operations. On construction sites, workers only need to complete quick butt joint and bolt fixing to realize frame assembly.

This innovative connection mode completely avoids structural hidden dangers such as welding cracks, welding deformation and joint rust caused by traditional welding processes. Standardized bolted connections ensure uniform stress at all structural nodes, strong connection toughness and stable overall coordination. The assembled frame structure has good flexible deformation capacity, which can absorb external impact force through micro deformation when encountering earthquakes and strong winds, effectively improving building disaster resistance. In addition, the bolted assembly structure supports complete disassembly, transfer and secondary reassembly, realizing repeated cyclic utilization of metal frames.
