A corrugated sheet is a metal sheet that is roll-formed into metal panels. Corrugated metal is an exposed fastener panel, meaning that each fastener is visible on the panel's surface.

The traditional shape of corrugated sheet metal is round and wavy. It is low cost, lightweight, durable, energy-efficient, long-lasting, and easy to install. Corrugated metal roofing is an excellent alternative to asphalt shingles or clay tile roofs. The durability of corrugated panels makes them a fit for both commercial and residential applications when used for metal roofing and metal siding projects. They are even used in other areas of the home including the ceiling, wainscoting, and fencing.
