Characteristics of Galvalume metal roof

1. Strong corrosion resistance

The corrosion resistance of the galvalume metal roof mainly comes from the protection of the metal roof surface coating. The galvalume coating is evenly and tightly coated on the steel surface by hot-dip coating.The galvalume coating has strong corrosion resistance and can effectively prevent the steel from being corroded and extend the service life of the metal roof.

2. Good weather resistance

The galvalume metal roof can effectively resist the harsh climate environment.For example, in harsh environments such as strong ultraviolet rays, acid rain, wind and sand, the galvalume metal roof can remain stable for a long time, is not easy to deform and age, and has a long service life.

3. High thermal reflectivity

The galvalume coating has a high thermal reflectivity, which can isolate high temperature, reduce indoor temperature, and improve indoor comfort.

4. Convenient installation

The galvalume metal roof is easy to install and can be installed in a short time, shortening the construction period.

5. Fire retardant

The galvalume metal roof is fireproof and also has a certain flame retardant ability.Enhance the safety level of the building.
