Special Constructions 1.5mm Corrugated Steel Roofing Sheets Galvanized Corrugated Roofing
1．Product Overview
Special constructions 1.5mm corrugated steel roofing sheets are designed for warehouse buildings, industrial buildings, workshop roofing systems, and special construction projects requiring lightweight structure and corrosion resistant roofing panels.
The corrugated galvanized roofing sheet combines structural rigidity with flexible installation performance. Corrugated wave design improves load distribution and drainage performance, while galvanized and painted surfaces support outdoor durability and weather resistance.
2．Technical Solution
The roofing sheet is manufactured according to JIS G3322 CGLCC, ASTM A792, and EN 10169 DX51D+AZ standards.
The product uses galvanized or galvalume substrate with color coated surface treatment. Paint systems including PE, SMP, PVC, and PVDF can be selected according to environmental exposure and coating durability requirements.
Wave width is 76mm and wave height is 17mm, supporting roofing stiffness and installation stability for industrial and civil building applications.
