Songchen Steel Co., Ltd, a leading enterprise in the metal material industry with over 20 years of experience, has developed high-performance foldable container houses by combining self-produced high-quality steel materials and innovative mechanical folding technology. These foldable container houses take high-strength galvanized steel pipe and cold-formed steel as the main structural materials, with the folding mechanism designed by professional mechanical engineers, adopting high-quality sliding rails, hinges and locking devices, which can realize fast folding and expansion, and the whole process can be completed by 2-3 people in 30 minutes without the help of large mechanical equipment. The folded volume of the product is only 1/3 of the expanded volume, which greatly reduces the transportation volume and storage space, and a single truck can transport 6-8 folded units at the same time, effectively reducing the logistics and storage cost for customers. The main frame of the foldable container house is made of high-strength profile steel with precise welding technology, ensuring the structural strength and stability of the product in the expanded state, and the product can withstand wind load of 0.5kPa and snow load of 0.3kPa, complying with the modular building technical standards. The wall adopts a foldable composite insulation structure, with high-density rock wool insulation cotton as the core insulation material, which has excellent thermal insulation and fireproof performance, with a fire resistance rating of Grade A and a thermal conductivity coefficient of less than 0.04W/(m·K). The foldable container houses are pre-equipped with basic water and electricity systems in the factory, and the internal space can be flexibly arranged after expansion, which can be used as dormitories, offices, temporary meeting rooms and other functional spaces, and is widely applied in construction sites, emergency disaster relief, outdoor exploration, mobile commerce and other scenarios. In the emergency resettlement project after the flood in Pakistan, the company’s foldable container houses were quickly transported to the disaster area and expanded for use, with more than 200 units put into use within 2 days, providing a safe and comfortable living space for the affected people, and the product’s fast folding and expansion performance and stable quality were highly praised by the local government and international relief organizations. The company has a spot inventory of 100,000 tons of steel materials and an automated production line, with an annual output of more than 15,000 foldable container house units, and can undertake large orders of 10,000 tons of letter of credit, providing batch and customized products for global customers. All products have passed CE certification and mechanical performance testing, with a service life of more than 10 years, and have been sold to more than 100 countries and regions around the world.
