Songchen Steel Co., Ltd, a leading metal material supplier with over 20 years of industry experience and an annual turnover exceeding 300 million USD, manufactures high-performance 40ft container houses by leveraging self-produced premium steel materials including galvanized steel, carbon steel, stainless steel and PPGI/PPGL steel, integrating the whole industrial chain of processing, manufacturing, sales and logistics. Adhering to international ISO container size standards, the 40ft container house features an external dimension of 12000mm×2400mm×2800mm and an internal usable area of approximately 26 square meters, offering ample space for flexible functional division, such as multi-person living quarters, comprehensive offices, or combined living and storage spaces, perfectly meeting the large-scale space demands of various projects. The main frame is crafted from high-strength profile steel with a thickness of 2.0-2.5mm, processed via CNC cutting and full-welded technology, boasting a static load-bearing capacity of over 500kg/㎡ and dynamic load-bearing capacity of 200kg/㎡, and can be stacked up to 4 layers under static conditions, complying with building safety standards across the globe. The wall and roof adopt a five-layer composite insulation structure: outer galvanized steel plate + 100mm high-density rock wool insulation cotton + fireproof board + aluminum foil insulation layer + inner galvanized steel plate, with a thermal conductivity coefficient as low as 0.035W/(m·K), Grade A fire resistance rating and sound insulation effect over 45dB, enabling adaptation to extreme climates like high temperature (above 40℃), low temperature (below -20℃), high humidity and aridity. All 40ft container houses are pre-equipped with a complete integrated system in the factory, including concealed flame-retardant electrical wiring with leakage and overcurrent protection, food-grade stainless steel water supply and drainage pipelines, large-area sliding glass windows for ventilation and lighting, and basic sanitary facilities. On-site installation only requires hoisting and connection of water and electricity, allowing immediate use without additional decoration, which drastically shortens the project construction period. In the large-scale highway construction project in East Africa, the company’s 40ft container houses were deployed as staff dormitories and canteens; each dormitory was rationally divided into 6 single bed spaces with a public activity area and storage cabinets, while the canteen unit was equipped with a simple kitchen system and dining area accommodating over 30 people simultaneously. These products withstood high temperatures, sandstorms and heavy rains with stable structural performance and intact functional facilities, earning high recognition from the construction unit. The house body surface is treated with a two-layer anti-corrosion process of hot-dip galvanizing (zinc layer thickness >90μm) and electrostatic powder coating (60-80μm), delivering excellent corrosion, salt spray and weather resistance, maintaining no rust or paint peeling for over 10 years in coastal and industrial areas, effectively extending the service life. With a spot steel inventory of 100,000 tons and an automated production line, the company achieves a monthly output of over 3,000 40ft container house units, and can undertake large orders with a 10,000-ton letter of credit, providing batch production and personalized customization services (including external color matching, internal layout optimization, and addition of solar power generation, rainwater recovery systems, etc.). All products have passed CE, ISO and environmental management system certifications, with a service life of over 18 years and a recycling rate exceeding 85%, aligning with global green building and sustainable development concepts. The company’s global logistics network covers more than 100 countries and regions in South America, Southeast Asia, the Middle East and Africa, enabling delivery via sea, land and combined transportation, with professional on-site installation teams providing technical guidance to ensure construction accuracy and progress.
