Songchen Steel’s 20ft container houses are designed with two structural forms: fixed and foldable, with the foldable type enabling folding into a small volume (only 1/3 of the expanded size) for transportation and storage, further reducing transportation and storage costs, and a single truck can transport 6-8 folded units at a time, making it more suitable for emergency projects and mobile building needs such as emergency disaster relief and outdoor exploration. The foldable 20ft container house adopts an innovative mechanical folding design, with high-quality stainless steel hinges, precision sliding rails and heavy-duty locking devices, and the folding and expansion process can be completed by 2-3 people in 20-30 minutes without large construction machinery, realizing rapid deployment and use, which is an ideal choice for emergency resettlement projects. In the South Asian earthquake emergency resettlement project, the company’s foldable 20ft container houses were airlifted to the disaster area and quickly expanded for use, with over 500 units put into operation within 3 days, providing safe and comfortable temporary living space for the affected people, and the product’s stable performance and fast deployment speed won high praise from international relief organizations. Adopting a standardized and modular design, the 20ft container house has all components produced in unified specifications, realizing product interchangeability and combination; multiple units can be freely combined horizontally and vertically to form large-scale building complexes with larger space and more complete functions, such as multi-person dormitories, comprehensive offices, medical clinics and small hotels. The combination part adopts high-strength connecting pieces with good sealing performance, effectively preventing water seepage and air leakage, and ensuring the firmness and stability of the combined structure. In the African rural infrastructure construction project, the company’s 20ft container houses were combined to form a rural primary school and a village medical clinic: 4 units were combined horizontally to form two classrooms each accommodating 20 students, and 2 units were combined to form a medical clinic with a diagnosis room and a pharmacy equipped with basic medical equipment, solving the problems of lack of education and medical resources in local rural areas and improving the local public service level. Built with an energy-saving and practical concept, the 20ft container house can be optionally configured with 500W-1000W solar power generation modules, energy-saving LED lighting and ventilation fans, realizing basic electricity self-sufficiency in off-grid areas, reducing reliance on traditional energy, and being suitable for use in remote mountainous areas, mining areas and other regions without power supply. In the remote Australian outdoor exploration base, the company’s 20ft container houses with solar power generation modules were put into long-term use, providing stable electricity supply for exploration personnel’s daily life and office work, solving the problem of power shortage in the remote area and ensuring the smooth progress of exploration work. The product’s internal space is designed in a humanized way, with a reasonable layout of storage space and activity space, and an internal height of 2.4m ensuring user comfort; the anti-slip floor is made of high-strength steel plate with anti-slip patterns, featuring excellent wear resistance and anti-slip performance, effectively preventing slip and fall accidents and ensuring user safety. The 20ft container house has excellent safety performance, with a fireproof and explosion-proof design; all electrical components use flame-retardant and explosion-proof products, internal decoration materials use non-combustible materials, and the product is equipped with smoke alarms, fire extinguishers and other fire safety facilities, complying with fire safety standards of various countries and regions, ensuring the personal and property safety of users. In the Middle Eastern petrochemical plant construction project, the company’s 20ft container houses with enhanced fire and explosion protection design were used as on-site temporary offices and operation rooms, withstanding the test of the harsh chemical environment, and the safety performance was highly recognized by the project owner. The company provides a complete after-sales service system for 20ft container houses, including a 3-year free warranty for the main structure, 2-year for the integrated system and 1-year for wearing parts; the company has established after-sales service centers in major global regions, with professional technical personnel and sufficient spare parts in stock, providing 24-hour online technical support and on-site maintenance services within 72 hours upon receiving customer requests, solving the worries of customers in the use process. With high cost performance, the product price is lower than that of traditional temporary buildings of the same size, and the fast installation speed, low maintenance cost and long service life reduce the overall project cost by more than 50%, making it an ideal choice for customers with temporary building needs and limited budgets.
