Songchen Steel Co., Ltd. leverages its advanced steel processing and manufacturing capabilities to develop expandable container houses that feature innovative structural design and high-quality steel material application. These expandable container houses are constructed with the company’s core products including galvanized steel, stainless steel and PPGI/PPGL steel, ensuring the overall structural strength and durability of the product. The biggest highlight of the expandable container house is its foldable and expandable design, which can be folded into a standard container size during transportation and storage, greatly reducing the transportation volume and storage space, and a single truck can transport multiple expandable container house units at the same time, effectively reducing the logistics cost for customers. When in use, the product can be quickly expanded to 2-3 times the original size through a simple mechanical operation, forming a spacious living and working space, which fully meets the needs of users for large space in different scenarios. The expandable container house adopts a multi-layer composite wall structure, including high-strength steel plate, high-density thermal insulation cotton and fireproof board, which has excellent thermal insulation, fireproof and sound insulation performance, and can adapt to the temperature differences of different regions and ensure the comfort of the internal space. The product is widely applied in various scenarios such as construction site temporary accommodation, emergency disaster relief resettlement, outdoor exploration base and mobile commercial service points. In the emergency resettlement project after natural disasters in Africa, Songchen’s expandable container houses have realized rapid deployment and expansion, providing a safe and comfortable living space for a large number of affected people in a short time, and the stable structure and complete facilities have won high recognition from the local government and international relief organizations. The expandable container house is pre-equipped with integrated water, electricity and gas systems in the factory, and the internal layout can be flexibly adjusted according to the user’s needs, such as dividing into bedrooms, living rooms, kitchens and bathrooms, meeting the diverse living and working needs of users. The company’s professional technical team of more than 100 people has carried out strict structural calculation and performance testing on the expandable container house, ensuring that the product has excellent anti-seismic, anti-wind and load-bearing performance, complying with the building safety standards of different countries and regions. With a spot inventory of 100,000 tons of steel materials and advanced production equipment, the company can realize the mass production of expandable container houses, and undertake large orders with a letter of credit of 10,000 tons, meeting the large-scale demand of customers for expandable container houses in large projects. The product has passed multiple international certification standards such as CE, and the quality is recognized by the global market, and has been sold to more than 100 countries and regions worldwide, with perfect after-sales service to ensure the smooth use of customers.
