What is Galvalume?

We all know that protecting steel from oxidation is a necessary request for steel products. Steel Coils Manufacturers often use one common method we have already know as Galvanizing to prevent the steel from rust and corrosion. While there is another method has a better rust -resistance performance than Galvanizing which is called Galvalume. But what is Galvalume? Below we will have a basic introduction.

Galvalume is a coating consisting of zinc, aluminum, and silicon that is used to protect steel from oxidation. It is similar to Galvanizing in that it is a sacrificial metal coating that protects the base metal.

What is Galvalume Used For?

Galvalume is primarily used to protect iron-based alloys that are prone to rust. Galvalume steel coil is better able to resist oxidation than common steel coil because the zinc and aluminum protect the underlying steel from the environment. The zinc also will more readily oxidize than the steel it contacts. This protection method is similar to the galvanizing.

When is Galvalume Used?

For instance, the application of Galvalume Steel Coil. One of the most popular applications of Galvalume Steel Coil is for outdoor metal paneling and roofing. Galvalume steel coil is used because it has superior resistance to corrosion in outdoor environments than standard Galvanized Steel Coil. It is able to resist corrosion when exposed to snow, ice, and rain.

When Should Galvalume Not Be Used?

Galvalume should not be used in alkaline environments. The aluminum in Galvalume Steel Coil does not hold up well to that type of environment, so Galvanized Steel Coil may be a better choice in that instance. Also, Galvalume Steel Coil does not do well if it is damaged. If the panel will be subject to scratches and indentation, then galvanized steel may be a better choice for the application. Even fastener installation may be enough to damage the Galvalume Steel Coil.
