Songchen Steel Co., Ltd, a professional metal material supplier with over 20 years of industry experience and more than 100 professional technical talents, manufactures high-performance folding container houses by integrating self-produced premium steel materials and innovative mechanical folding design. These folding container houses take high-strength galvanized steel pipes, cold-formed steel and PPGI/PPGL steel as core structural materials, with the folding mechanism independently developed by the company’s R&D team, adopting high-quality stainless steel hinges, precision sliding rails and heavy-duty locking devices. The whole folding and expansion process can be completed by 2 professional operators in 20-30 minutes without large construction machinery, and the folded volume is only 1/4 of the expanded size, which drastically reduces transportation and storage costs—one standard truck can transport up to 8 folded units at a time, making it extremely suitable for long-distance international transportation and emergency project deployment. The main frame of the folding container house is processed by numerical control cutting and precise welding technology, with a yield strength of more than 345MPa, ensuring structural stability and load-bearing capacity in the expanded state; it can withstand a wind load of 0.6kPa and a snow load of 0.35kPa, fully complying with international modular building technical standards. The wall and roof adopt a foldable composite insulation structure, consisting of galvanized steel plate, high-density rock wool insulation cotton (thermal conductivity coefficient <0.04W/(m·K)) and fireproof board, with a fire resistance rating of Grade A and sound insulation effect over 40dB. The product is pre-equipped with integrated water and electricity systems, including concealed flame-retardant wiring, standard sockets and lighting fixtures, in the factory; after expansion, the internal space can be flexibly arranged into single/double dormitories, temporary offices or small service spaces, without additional on-site decoration. Folding container houses are widely applied in emergency disaster relief, construction site temporary accommodation, outdoor exploration bases and mobile commercial service points. In the flood emergency resettlement project in Southeast Asia, the company’s folding container houses were airlifted to the disaster area and quickly expanded for use, with over 300 units put into operation within 3 days, providing safe and comfortable living space for the affected people. The products withstood high temperature, humidity and heavy rain weather, with zero structural failures and functional problems, winning high recognition from the local government and international relief organizations. All folding container houses have passed CE certification and mechanical performance testing, with a service life of more than 12 years under normal use; the surface of the house body is treated with hot-dip galvanizing + electrostatic powder coating, with a zinc layer thickness of over 85μm, which has excellent corrosion resistance, effectively resisting salt spray, atmospheric corrosion and chemical erosion, and can be used for a long time in coastal, industrial and other harsh environments. The company has a spot inventory of 100,000 tons of steel materials and an automated production line, with an annual output of over 15,000 folding container house units, and can undertake large orders with a 10,000-ton letter of credit, providing batch production and personalized customization services for customers in more than 100 countries and regions worldwide, with perfect global logistics distribution and after-sales service to ensure the smooth implementation of customer projects.
