Songchen Steel’s prefab container houses take the concept of "energy saving, environmental protection and high efficiency" as the core, and all raw materials adopt recyclable steel and environmental protection insulation materials, without adding any harmful substances in the production process, complying with the EU REACH environmental protection standards. The product is equipped with a solar power generation module and a rainwater recovery system as an optional configuration, which can realize the self-sufficiency of electricity and water resources in the off-grid area, reducing the dependence on traditional energy and water supply systems, and is especially suitable for remote areas such as mining areas and mountainous areas. In the gold mine construction project in West Africa, the company’s prefab container houses with solar power generation system have been put into use for a long time, providing stable electricity supply for lighting, office equipment and daily life of the mining staff, and the rainwater recovery system effectively solves the problem of water shortage in the mining area, saving more than 50% of the project operation cost for the customer. The prefab container houses adopt a passive energy-saving design, with large-area low-emissivity insulating glass installed on the south side to make full use of solar energy for heating in winter, and the north side is equipped with thickened insulation layers and heat-insulating shutters to reduce heat loss in winter and heat gain in summer, with the annual energy consumption of air conditioning and heating reduced by more than 40% compared with traditional temporary buildings. The company has established long-term cooperative relations with well-known steel enterprises such as Shandong Iron and Steel and Shagang Group, ensuring the stable supply of high-quality raw materials, and the strict quality inspection system from raw material incoming to finished product delivery ensures that each prefab container house meets the high quality standards. The prefab container houses have the characteristics of disassembly and reuse, and can be disassembled and transported to other projects for reassembly and use after the completion of the project, with the disassembly and assembly loss rate of less than 5%, greatly reducing the construction waste and project cost. The company provides a full range of after-sales service for prefab container house products, including 24-hour online technical support, on-site maintenance and regular return visit, solving the worries of customers in the use process.
