Yaheng Tengfei's folding container houses are designed with waterproof features. The patented technology used in the manufacturing process includes waterproof devices at the folding connections, effectively preventing water ingress during heavy rain or storms. The roof is constructed using high-quality C-shaped steel for the frame, and the gaps are sealed with qualified waterproof sealant, ensuring resistance to cracking and oxidation in various weather conditions. During installation, sealing strips are applied at the joints of the two faces, providing a tight bond to prevent ventilation and leakage.
