Songchen Steel’s 40ft container houses have excellent compatibility and combination performance, and multiple units can be freely combined horizontally and vertically to form large-scale building complexes with more complete functions and larger space, such as multi-storey staff dormitories, comprehensive office buildings, modular hospitals and small shopping malls, meeting the large-scale and complex building needs of various projects. The combination part adopts high-strength connecting pieces with good sealing performance, which not only ensures the firmness and stability of the combined structure, but also effectively prevents water seepage and air leakage, ensuring the overall use effect and service life of the building complex. In the large-scale industrial park construction project in Southeast Asia, the company’s 40ft container houses were combined to form a three-storey staff dormitory building and a two-storey office building; the dormitory building was formed by vertical stacking of 3 layers and horizontal combination of 8 units per layer, accommodating more than 140 staff at the same time, and the office building was formed by horizontal combination of 6 units per layer and vertical stacking of 2 layers, with a reception area, open office area and meeting room. The combined building complex was quickly installed and put into use within 20 days, meeting the urgent needs of the industrial park for staff accommodation and office space. The product’s combination design complies with international modular building connection standards, with standardized connecting pieces and installation interfaces, enabling fast and convenient combination and disassembly, and the disassembly and re-combination can be completed without damaging the structure and components, realizing the flexible adjustment of the building space according to the project needs. For projects with changing space needs such as temporary exhibition halls and construction site command centers, the 40ft container house can be quickly re-combined to adjust the space layout and functional division, improving the space utilization rate and project flexibility. The 40ft container house is equipped with a complete fire safety system, including smoke alarms, fire extinguishers, emergency lighting and escape passages, with all electrical components using flame-retardant and explosion-proof products, and the internal decoration materials using non-combustible materials, complying with the fire safety standards of various countries and regions, effectively preventing the occurrence and spread of fire and ensuring the personal and property safety of users. In the petrochemical plant construction project in the Middle East, the company’s 40ft container houses with enhanced fire and explosion protection design were used as on-site temporary command centers and operation rooms, withstanding the test of the harsh chemical environment, and the fire safety system effectively prevented potential fire hazards, ensuring the safety of the construction personnel. The company provides comprehensive supporting services for 40ft container houses, including the supply of various functional accessories such as air conditioners, water heaters, beds, desks and chairs, and can also provide customized furniture and equipment according to customer needs, realizing one-stop procurement for customers and reducing the procurement cost and time of customers. The company’s global logistics and distribution system can deliver the 40ft container houses and their supporting facilities to the customer’s designated location at the same time, with unified transportation and installation, ensuring the matching and normal use of the product and supporting facilities. The 40ft container house has a high investment return rate; for the rental and operation industry such as tourism homestays and temporary accommodation, the product has the advantages of fast construction speed, low investment cost, long service life and low maintenance cost, and can be quickly put into use to generate economic benefits, with a short investment recovery period. In the Southeast Asian tourism resort project, the company’s 40ft container houses were transformed into homestay suites, with personalized decoration and layout, and the investment recovery period was less than 3 years, bringing good economic benefits to the investors. With the continuous development of the global modular building industry, Songchen Steel is committed to the research and development and innovation of 40ft container house products, integrating more intelligent and green technologies, such as the development of intelligent 40ft container houses with remote monitoring and automatic management functions, and green 40ft container houses with zero carbon emission, making the product more in line with the development trend of the global building industry and creating more value for customers.
