Color-steel houses are a new concept of eco-friendly and economic buildings, constructed with light steel H-section and channel steel as the framework, sandwich panels as the wall materials, and assembled using standardized modular series. The components are connected by bolts or welding. They can be easily assembled and disassembled, achieving universal standardization in temporary construction. This has established an architectural philosophy of environmental protection, energy conservation, and speed, bringing temporary housing into a field of serialized development, integrated production, standardized supply, and reusable products.
