We have established a quality management system that covers the entire product process. In the incoming material process, all raw materials and accessories must undergo standardized entry inspection procedures. During the production process, we have established multiple key quality control points to continuously monitor processes such as cutting accuracy, welding quality, and structural assembly. Before leaving the factory, each prefabricated house must undergo systematic testing, including structural strength, sealing performance, and durability of the folding mechanism. These standardized quality control processes constitute the fundamental guarantee for product consistency and reliability.
