Songchen Steel Co., Ltd, with over 20 years of steel manufacturing experience and a professional technical team of more than 100 talents, manufactures high-precision flat pack container houses by integrating self-produced high-quality steel materials and advanced prefabrication technology, adhering to the design concept of "standardization, disassembly and assembly, and reusability". Flat pack container houses take galvanized steel profiles, PPGI/PPGL steel plates and stainless steel connecting pieces as core raw materials, with all components pre-processed, cut and punched in the factory with high precision, and the dimensional accuracy error is less than 1mm, ensuring the smooth assembly of on-site components without secondary processing. The product is a fully disassembled modular building, with all components packed in standard cartons or wooden cases for transportation, and the volume of packed components is only 1/5 of the assembled finished product, which drastically reduces transportation costs—one 40ft sea container can transport up to 10 sets of 20ft flat pack container house components, making it extremely suitable for long-distance international sea transportation. The main frame of the flat pack container house is made of high-strength galvanized steel profiles with a yield strength of more than 300MPa, connected by high-strength bolts and nuts, without on-site welding, which not only ensures the firmness and stability of the structure, but also makes the disassembly and assembly process simple and fast; a professional installation team of 2 people can complete the assembly of a single 20ft flat pack container house in 4-6 hours, and the disassembly process can be completed in the same time, with no damage to the components during disassembly and assembly, realizing repeated disassembly, assembly and reuse. The wall and roof of the flat pack container house adopt a prefabricated composite insulation panel structure, consisting of galvanized steel plate, high-density rock wool insulation cotton and fireproof board, with a thermal conductivity coefficient of <0.04W/(m·K), fire resistance rating of Grade A and sound insulation effect over 40dB, which has excellent thermal insulation, fireproof and sound insulation performance, and can adapt to various climatic environments such as high temperature, low temperature, high humidity and aridity. The product is pre-equipped with standardized installation interfaces for water, electricity and gas systems in the factory, and the internal electrical system, water supply and drainage system and ventilation system can be quickly connected during assembly, with all wiring and pipelines concealed, ensuring the beauty and safety of the internal space. Flat pack container houses have a flexible and diverse internal layout, which can be freely designed and divided according to customer needs, and can be customized into dormitories, offices, medical clinics, shops and other functional spaces, with the optional configuration of air conditioning, heating, intelligent lighting and other equipment, meeting the diversified needs of different industries and scenarios. The product is widely applied in various scenarios such as construction site temporary buildings, remote area working and living quarters, tourism homestays, rural infrastructure construction and emergency disaster relief, and is especially suitable for projects with limited transportation conditions and large-scale batch construction. In the rural poverty alleviation resettlement project in South Asia, the company’s flat pack container houses were used as rural residents’ houses, with each unit customized into a small family house with a living room, two bedrooms and a simple kitchen, and more than 1,000 units were assembled and put into use within 2 months, solving the housing problem of local poor residents; the products withstood the test of monsoon and heavy rain weather, with stable structural performance and comfortable internal environment, winning high recognition from the local government and residents. All components of the flat pack container house are treated with anti-corrosion and anti-rust technology, the steel profiles are hot-dip galvanized (zinc layer thickness >85μm), and the steel plates are coated with electrostatic powder coating, which has excellent corrosion resistance, salt spray resistance and weather resistance, and can be used for more than 15 years in various harsh environments, with a service life of more than 10 times of repeated disassembly and assembly. The company has a spot inventory of 100,000 tons of steel materials and an automated production line, with an annual output of over 20,000 sets of flat pack container house components, 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. All flat pack container houses have passed CE certification, ISO certification and environmental management system certification, with all raw materials made of 100% recyclable steel, a recycling rate of more than 85% after the end of service life, no harmful materials added in the production process, and in line with the global green building and sustainable development concept. The company provides a complete one-stop solution service for flat pack container houses, including product design, component production, transportation, on-site assembly guidance, after-sales maintenance and spare parts supply, with professional technical personnel providing on-site installation training for the customer’s installation team, helping customers master the assembly and disassembly skills, and realizing the self-assembly of customers. The company has a perfect global logistics network and storage system (storage area >50,000 square meters), which can deliver flat pack container house components to the customer’s designated location in the shortest time, with low transportation costs and fast delivery speed, ensuring the smooth progress of the customer’s project.
