Corrugated Metal Roofing Explained

Corrugated Metal Roofing is a popular building material, and it offers a number of advantages over traditional asphalt shingles. Corrugated metal roofing is also called galvanised corrugated metal roofing, galvanized tin roofing, corrugated roofing, or galvanised sheet metal roofing and sometimes acronymed as CGI. It is made from rolled steel (corrugation) to a specified thickness, which is often greater than one inch. It can be used for both interior and exterior roof applications because of its excellent stiffness/weave characteristics.Find additional information at corrugated metal roofing.

Metal roofing can be produced in various colours and finishes depending on the manufacturer’s specification. It is typically available in hot dip galvanized mild steel (CPVC), cold rolled (CPVC/GSR), u-shaped (CPVC/GSR), flat lap (CPVC/GSR), diamond-shape (CPVC/GSR), and shingle (lap) materials. It is also available in a variety of thicknesses, lengths, pitches, sheaves, widths, and manufacturing process. One of its unique features is that it can be easily bent, twisted or sheared; hence, it is often incorporated as roofing components in helical, U-shaped and N-shaped designs. Corrugated metal sheets are also used to roof swimming pools and other water features.

The galvanized roofing is made with two or more metal sheets and is coated with asphalt tar, or asphalt flakes. The coating dries to a smooth, glossy finish. Corrugated metal roofing has many advantages over alternative materials such as asphalt shingles, fiberglass, wood, tiles, linoleum, etc. For instance: it requires relatively less repair and maintenance, has longer life, provides excellent resistance to ozone, flame, heat, and weather, is lightweight and inexpensive, has excellent noise and heat insulation properties, and provides an excellent aesthetic appearance.
