Wanqing New Materials Seamless Roof Workshop

This 15,775.84 m² workshop in Changle, Weifang, Shandong features a 35-meter ultra-long polyurethane sandwich panel roof system with no transverse laps, fundamentally eliminating leakage risks and thermal bridges at joints. Concealed fasteners and precision waterproofing details deliver a seamless, attractive roof surface. On-site testing confirmed that thermal performance fully meets the temperature control demands of new materials production, making this project a representative solution in Derun Heavy Steel's large-span industrial roofing portfolio.
