1. Deficiencies of Traditional Construction Site Worker Dormitories

To fully recognize the innovative value of Lida Group’s eco-friendly sandwich panel dormitories, it is essential to analyze the inherent deficiencies of traditional temporary worker dormitories. For decades, construction enterprises have prioritized low upfront costs and rapid construction progress for temporary facilities, ignoring long-term living quality, environmental protection benefits and reusable value. Most traditional dormitories have obvious defects in environmental performance, living comfort, structural safety and economic efficiency, restricting the standardized development of construction site management.

In terms of environmental protection, traditional temporary buildings cause serious resource waste and environmental pollution. Wooden dormitories consume a large amount of natural wood resources and are prone to rot and discard after short-term use. Ordinary color steel plate dormitories use low-quality adhesive and foam core materials containing formaldehyde and other harmful substances, which will volatilize toxic gases for a long time after installation, polluting indoor air and endangering workers’ physical health. In addition, most traditional temporary buildings are disposable structures. After the completion of construction projects, the buildings are directly demolished and scrapped, generating a large amount of construction waste that is difficult to recycle, causing continuous pressure on the ecological environment and failing to meet the global construction industry’s ESG green assessment standards.

In terms of living comfort, traditional dormitories have poor comprehensive functional performance. Ordinary color steel plates have single thermal insulation performance, failing to isolate external extreme temperatures effectively. In high-temperature summer, indoor temperature rises sharply, while in cold winter, indoor heat dissipates rapidly, resulting in sweltering and freezing living environments throughout the year. Meanwhile, traditional panel structures have weak sound insulation effects, unable to block external construction noise and outdoor wind noise, seriously affecting workers’ rest quality. Moreover, low-quality building panels are prone to water seepage, wall peeling and mold growth in humid and rainy environments, leading to damp and unsanitary indoor spaces and easily triggering respiratory and skin diseases among resident workers.

In terms of structural safety and economy, traditional dormitories have low structural stability and high comprehensive life-cycle costs. Ordinary temporary building panels have low structural strength, poor wind resistance and seismic performance, and cannot resist extreme weather such as strong winds, rainstorms and sandstorms, bringing potential safety hazards. In terms of cost, although traditional dormitories have low one-time construction investment, they require frequent maintenance, renovation and replacement. The disposable design leads to repeated construction investment for subsequent new projects, resulting in extremely high comprehensive operating costs for construction enterprises.

2. Structural Composition and Core Properties of Lida Group’s Eco-Friendly Sandwich Panels

Lida Group’s eco-friendly sandwich panel is a customized composite green building material independently developed for temporary worker dormitories. Adopting a mature three-layer sandwich composite structure, the panel takes high-strength galvanized steel plate as the outer protective layer, high-density flame-retardant rock wool or EPS as the middle core layer, and environmentally friendly color-coated steel plate as the inner decorative layer. All raw materials meet international environmental protection and building safety standards, free of formaldehyde, benzene and other volatile harmful substances. Through automated pressing, bonding and integral forming technology in standardized factories, the sandwich panel achieves perfect integration of multiple excellent performances, providing reliable material support for comfortable, safe and green worker dormitories.
