Metal Roofing Sheet Panels

Galvanized Corrugated Steel Sheet VS Galvalume Corrugated Steel Sheet Galvanized corrugated roofing sheet and galvalume corrugated roofing sheet are two popular roofing materials used in construction. Both these materials have their own unique properties and advantages. Here are some key differences between galvanized corrugated roofing sheet and galvalume corrugated roofing sheet: 1. Material Composition: Galvanized corrugated roofing sheet is made of steel that has been coated with a layer of zinc to prevent corrosion. Galvalume corrugated roofing sheet, on the other hand, is made of steel that has been coated with a layer of zinc, aluminum, and silicon to provide greater protection against corrosion. 2. Corrosion Resistance: While both materials are designed to resist corrosion, galvalume corrugated roofing sheet provides greater protection against rust and corrosion than galvanized corrugated roofing sheet. This is because the aluminum and silicon in the galvalume coating prov…
