Corrugated Galvanised Iron Sheet is prevent from corrosion by coating ordinary steel or iron sheets with a layer of zinc.The galvanisation process ensures that the steel sheet remains resistant to rust,effectively block moisture and oxygen to protect the steel sheet from rust or corrosion.
The corrugation increases the strength and rigidity of the steel sheet, making it excellent in resisting adverse weather conditions, impacts and other external factors. In addition, galvanized corrugated sheets also have the ability to reflect sunlight, which helps to reduce the temperature of the building.

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.
GI Coil Surface Structure
The steel is immersed in molten zinc liquid to form a metallurgical bond between the zinc and the steel, to form a uniform and dense zinc layer on the surface of the steel,against bare steel from the natural elements that cause corrosion.The thickness and uniformity of the zinc layer directly affect the performance of galvanized steel.The coating weight we supply can range 30-275g/m2,also can be produced as required.
