GI Profile Sheet is used in various roof structures, made of galvanized sheets, available in various thicknesses and forms. They can be used as a single layer without insulation, or as a multi-layer roof and wall application, where the insulation layer is laid between two corrugated sheets. GI roof has good wind and earthquake resistance, suitable for various climate conditions.

Galvanized sheet is pressed surface to form a corrugation structure. The corrugated design enhances the mechanical strength, also makes it more pressure-resistant and weather-resistant. The corrugated design can effectively guide the water flow out and avoid water accumulation, widely used in roofing materials, especially in rainy areas.
Technical of Corrugated Roofing Sheet
1.Forming type-Cold form
2.Machine-Rolling form machine
The galvanized layer of galvanized steel coil forms a barrier that prevents moisture and other corrosive substances from entering the underlying steel, making galvanized steel a resistant and rust-resistant material that can be used in a variety of applications.
