Mobile housing units are a new concept of environmentally friendly and economical temporary structures, framed with light steel, lined with sandwich panels, and assembled using standard modular series. The components are connected with bolts. They can be easily and quickly assembled and disassembled, achieving universal standardization in temporary construction. This approach has established an architectural philosophy of environmental protection, energy conservation, and speed, propelling temporary housing into a field of serialized development, integrated production,配套 supply, and reusable stock products.
