Songchen Steel’s 40ft container houses are designed with two structural types: fixed and expandable, with the expandable type enabling single or double-sided expansion to an internal usable area of 40-50 square meters, further improving space utilization and suiting scenarios like large offices, medical clinics and commercial stores with higher space requirements. Adopting a standardized design, all components are produced in unified specifications to realize part interchangeability, facilitating easy maintenance and replacement; damaged parts can be quickly replaced with spare parts, reducing product downtime and ensuring uninterrupted user experience. The product is equipped with a reinforced anti-seismic and wind-resistant structure, with high-strength connecting pieces installed at the bottom and frame joints, capable of withstanding an 8-degree earthquake and a Level 12 typhoon, making it suitable for construction in earthquake-prone and coastal typhoon-prone areas. In the Northern European wind power project construction, the company’s 40ft container houses with reinforced cold and wind resistance design were used as temporary control rooms and maintenance workshops, equipped with 150mm thick rock wool insulation layers and electric heating floors, maintaining an internal temperature above 18℃ even at -30℃, and the reinforced wind-resistant structure effectively withstood Level 10 strong winds without structural deformation or functional failure. Built with an energy-saving and environmental protection concept, the 40ft container house can be optionally configured with monocrystalline silicon solar power generation modules (conversion efficiency >22%), rainwater recovery and filtration systems, and energy-saving air conditioners, realizing self-sufficiency in electricity and water resources in off-grid areas, reducing reliance on traditional energy and water supply systems, and saving over 60% of operating costs for customers. In the remote West African mining area construction project, the company’s 40ft container houses with solar power generation and rainwater recovery systems were put into long-term use, providing stable electricity and water supply for miners’ daily life and office work, solving the problem of power and water shortage in the mining area and greatly cutting project operation costs. The company offers a one-stop solution service for 40ft container houses, covering product design, production, transportation, installation, after-sales maintenance and upgrade transformation, with professional project managers following up the entire project process to ensure smooth progress and goal achievement. Boasting rich experience in international project cooperation, the company is familiar with building standards, import and export policies and customs clearance procedures of different countries and regions, providing professional import and export services including product certification, document preparation and transportation arrangement to ensure smooth export. The perfect after-sales service system includes a 5-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 maintenance personnel and sufficient spare parts in stock, providing on-site maintenance services within 48 hours upon receiving customer requests. With high cost performance, the product price is lower than that of traditional prefabricated buildings of the same size, and the fast installation speed, low maintenance cost and long service life reduce the overall project cost by over 40%, making it an ideal choice for customers with large-scale building needs and high cost performance requirements. The 40ft container houses have been widely sold to more than 100 countries and regions, and successfully applied in large-scale projects such as African railway construction, Southeast Asian power plant construction, South American urban renovation and European renewable energy project construction, winning high praise from global customers with stable performance and high-quality services.
