Galvanized And Galvalume Steel Roofing

It is important to note that base metals can be combined, coated, or layered with additional metals in a variety of bonding processes. Two popular roofing materials that use this process of binding two or more dissimilar metals are referred to as galvanized and galvalume, each of which use steel as the base metal. Iron or steel can be coated with zinc this is known as a galvanized metal. The zinc acts as a protective layer to iron or steel to prevent rust. Galvalume is aluminum and zinc coated steel. The combination of aluminum and zinc is used once again as a protective layer to the steel. Steel exposed by itself without other protective metal coatings such as aluminum or zinc turns a reddish- or yellowish-brown flaky coating of iron oxide that is formed on iron or steel by oxidation, especially in the presence of moisture. It is what we refer to as rust.

Rust has been called the great destroyer and the evil. The Pentagon refers to it as the pervasive menace. It destroys cars, fells bridges, sinks ships, sparks house fires, and nearly brought down the Statue of Liberty. Rust costs America more than $400 billion per yearmore than all other natural disasters combined.
