Corrugated metal is available in sheets with wavy ridges, looking similar to rippled potato chips. This product is used in construction projects for roofing or siding. Roofs have been constructed corrugated metal for many years, and this type of material is becoming popular again due to its durability. It is lightweight and economical to install, and can be used on commercial buildings as well as residential homes. This type of roofing material is highly durable and is able support a large amount of weight without buckling.

Corrugated metal siding can be used for industrial buildings, as well as in residential construction. It is also known as "architectural siding." Homeowners are impressed by the fact that corrugated metal products may come with manufacturer's warranties of up to 50 years. Homes in coastal regions are more likely to use corrugated metal, since it is a moisture-resistant material. It also performs well in environments where there is a threat of strong winds, significant accumulation of snow, or storms.

Corrugated metal siding can be made from aluminum or steel. Aluminum is the material of choice in areas near the ocean, since the aluminum will react with the moist, salty air to form aluminum oxide. The result is a very durable coating that seals the metal and protects the product from wearing down over time. Since aluminum is a softer metal than steel, it can be damaged during hailstorms.

In areas that are prone to hail storms, corrugated metal siding fashioned from steel may be a better choice. It is less likely to be dented when hit by hail than aluminum is. This type of siding can rust over time, but it is possible to prolong the life of the product through the use of a corrosion-resistant coating.
