Songchen Steel Co., Ltd, a professional metal material supplier with over 20 years of industry experience, a spot steel inventory of 100,000 tons and an annual turnover of over 300 million USD, produces high-standard 20ft container houses in strict accordance with international ISO container size standards, using self-produced galvanized steel, carbon steel, stainless steel and PPGI/PPGL steel as core raw materials, and integrating advanced modular building technology and sophisticated manufacturing processes. The 20ft container house features an external dimension of 6000mm×2400mm×2800mm and an internal usable area of about 12 square meters, with a compact and reasonable structural design, easy transportation, installation and deployment, making it the most widely used standard modular building product in the global market, perfectly meeting the small and medium-sized space needs of various temporary and semi-permanent projects. The main frame is made of high-strength galvanized steel pipes (80mm×40mm, thickness 1.5-2.0mm) processed by CNC cutting and precise welding technology, with a static load-bearing capacity of over 400kg/㎡ and dynamic load-bearing capacity of 150kg/㎡, and can be stacked up to 3 layers under static conditions, with excellent structural stability and load-bearing capacity, complying with building safety standards of various countries and regions. The wall and roof adopt a four-layer composite insulation structure: outer PPGI steel plate + 80mm high-density rock wool insulation cotton + fireproof board + inner galvanized steel plate, with a thermal conductivity coefficient <0.038W/(m·K), Grade A fire resistance rating and sound insulation effect over 40dB, enabling adaptation to various climatic environments including tropical rainforests, arid deserts, cold regions and coastal areas, maintaining a comfortable internal temperature and a quiet use environment. All 20ft container houses are fully pre-assembled and debugged in the factory, including a concealed electrical system with flame-retardant copper core wires, leakage protection switches and standard international sockets, a simple water supply and drainage system with stainless steel pipes and drain pipes, a ventilation and lighting system with sliding glass windows and LED lighting fixtures, and basic internal decoration with fireproof ceilings and anti-slip floors. On-site installation only requires hoisting and connection of water and electricity, and a single unit can be installed and put into use within 1-2 hours without additional construction and decoration work, which greatly shortens the project construction period and reduces construction costs. The product is widely applied in various scenarios such as construction site single/double dormitories, temporary office spaces, remote area working quarters, tourism homestay single rooms, emergency disaster relief temporary resettlement houses and mobile commercial service points, demonstrating strong versatility. In the small-scale construction project in Southeast Asia, the company’s 20ft container houses were used as construction personnel dormitories and on-site offices; the dormitory type was equipped with two single beds, a wardrobe and a small desk, and the office type with desks, chairs and file cabinets, meeting the basic living and office needs of the construction personnel. The whole project’s temporary building construction was completed in 3 days, effectively improving the construction efficiency. The house body surface is treated with hot-dip galvanizing anti-corrosion technology (zinc layer thickness >85μm), and can be optionally coated with electrostatic powder coating with a variety of color options according to customer needs, which not only improves the anti-corrosion and weather resistance of the product, but also meets the personalized aesthetic needs of customers. The product has excellent corrosion resistance, capable of resisting salt spray corrosion, atmospheric corrosion and chemical erosion, and can be used for more than 15 years in coastal and industrial areas without rust and structural deformation. With an automated production line and a monthly output of over 5,000 20ft container house units, the company 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. The customization scope includes internal layout adjustment, addition of air conditioning, ventilation, solar power generation, intelligent security and other functional modules, and external appearance customization, meeting the diversified needs of different industries and scenarios. All products have passed CE certification, environmental management system certification and product quality verification, with a product qualification rate of 99.8%; the whole production process is under strict quality control, from raw material incoming inspection to finished product delivery testing, ensuring the high quality and high consistency of each product. The company has a storage area of more than 50,000 square meters and a perfect global logistics network, enabling delivery of 20ft container house products via sea, land and air transportation with low transportation costs and fast delivery speed; professional on-site installation teams provide technical guidance and installation services to ensure installation accuracy and product use effect. The 20ft container house is a green and environmentally friendly building product; all raw materials are recyclable steel, with a recycling rate exceeding 80% after the end of service life, no harmful materials added in the production process, and no dust, noise or construction waste generated during installation, complying with global green building and sustainable development concepts.
