Himei waterproof tiles are constructed using advanced hot-melt welding technology to ensure tight connection and waterproof performance between tiles. First, the joints of the tiles are heated to a molten state to soften the surface material. Then, the edges of adjacent tiles are tightly pressed together using professional welding equipment to form a solid integrated structure. This process not only ensures the sealing of the joints, but also enhances the wind pressure resistance and durability of the tiles, making it particularly suitable for building applications in high humidity and highly corrosive environments.
