Galvalume Steel Sheet in Coil

Release date: 2014-7-3

Product detailed

Similar to our hot dip galvanized steel sheets, the galvalume steel sheet in coil is also a popular type of metal coated steel in areas such as automobile, shipbuilding, electrical appliance, environmental protection, and machinery construction.

Advantages
The galvalume coating is an alloy made up of 55% aluminum, 43.3% zinc, and 1.6% silicon, formed under a high temperature up to 600. This alloy coating provides the galvalume steel coil with the following advantages.

Heat resistance
The 55% Al-Zn alloy coated steel sheet has heat resistance comparable with aluminum plated steel plates. It is able to work under maximum temperature of 300, and thus, it is often utilized to produce smoke stacks, ovens, lamp shade, and more.

Corrosion resistance
In the form of aluminum oxide coating, the aluminum in the coating provides the galvalume steel sheet with great resistance to corrosion, especially after the zinc layer is abraded.

High thermal reflectivity
The thermal reflectivity of galvalume steel sheet is two times of galvanized steels with the same thickness. Due to this, galvalume steel coils are widely used as thermal insulation material in construction and related industries.

Economical
As Al-Zn alloy coating has lower density than pure zinc coating, galvalume steel sheet in coil is 3% larger in area when compared with zinc coated steel coils with the same weight and coating thickness.
