Product Description
0.3mm Galvalume Steel Plate DX51D is widely used in building materials, home appliances, automobiles, environment, machinery, ships and other fields of a kind of alloy plated steel plate.Aluminized zinc steel plate is in the surface of the aluminum zinc alloy cover treatment, by 55% aluminum, 43.4% zinc and 1.6% silicon at 600℃ high temperature solidification and composition, the entire structure of aluminum-iron - silicon - zinc, forming a dense four element crystal alloy coating steel plate.
Advantage:
● Strong corrosion resistance, 3 times that of galvanized steel sheet.
● The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the
plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

Galvalume is primarily used to protect iron-based alloys that are prone to rust. Galvalume-coated steel is better able to resist oxidation than plain carbon steel 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 is similar to galvanized steel.
When is Galvalume Used?
One of the most popular applications of Galvalume steel is for outdoor metal paneling and roofing. Galvalume is used because it has superior resistance to corrosion in outdoor environments than standard galvanized steel. 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 does not hold up well to that type of environment, so galvanized steel may be a better choice in that instance. Also, Galvalume does not do well if it is damaged. If the panel will be subject to scratches and indentation, then galvanized steel may be better suited as the material for the application. Even fastener installation may be enough to damage the Galvalume coating.
