The longitudinal lap of pressurized steel plate should be located at the mold strip or wall beam, and both plates should be extended to the supporting members. Lap length: 350 mm for high-wave roof panels; 250 mm for low-wave roof panels with <10% roof gradient, 200 mm for low-wave roof panels with >10% roof gradient; 120 mm for wall panels. When lapping the roof, a through-length sealing tape should be set up between the seams of the panels.
