Light weight, the weight per square meter is less than 24kg, which can fully reduce the structure cost.

It is somewhat similar to galvanizing because it is a coating that protects metals. ​

Galvalume is mainly used to protect iron-based alloys that are prone to rust.

The main difference between the two is that galvalume is a combination of zinc, aluminum and silicon, while galvanizing is composed of 100% zinc.

color coated steel is obtained by subjecting hot-dipped galvanized steel sheet, agalvalume steel,or aluminum sheet to a surface chemical treatment (coating) ,
