１．Product Overview
0.14-1.5mm Galvanized Corrugated Roofing Sheet is manufactured from hot-dipped galvanized steel and formed into corrugated profiles for roofing and wall cladding applications. Produced from SGCC, SGCH, or G550 steel grades, the product combines lightweight construction with reliable structural performance for industrial, commercial, agricultural, and residential buildings.
The galvanized coating helps protect the steel substrate from corrosion, while the corrugated profile improves rigidity and load-bearing performance. The product is widely used in roofing systems, warehouses, workshops, prefabricated buildings, and steel structure projects.
２．Technical Solution
The roofing sheet is produced from hot-dipped galvanized steel coils and roll-formed into corrugated profiles. The galvanized coating acts as a protective barrier against atmospheric corrosion, extending service life in outdoor environments.
Available in multiple widths and lengths, the sheets can be selected according to roofing span requirements and installation conditions. The corrugated structure improves stiffness while reducing overall material weight.
