ASTM Aluzinc Galvalume Steel Coils GL AZ70-AZ200 Coated

AZ150 Coated Steel Galvalume Steel Coil GL Aluzinc Steel Coil

Galvalume Steel Coil introduction:

Due to the oxidation and corrosion of steel plates caused by moisture, a anti-corrosion protective layer must be added to the surface. Generally, anti-corrosion coatings are divided into hot-dip galvanized Zn and hot-dip aluminum zinc alloy Al Zn (aluminum zinc alloy composition is 55% aluminum, 43.5% zinc, and 1.5% silicon, abbreviated as 55% Al Zn). According to the datSoft Hard (<60),Medium Hard (60-85), Full Hard (85-95)a, the comprehensive anti-corrosion ability of 55% aluminum zinc plating is four times that of galvanized steel of the same thickness.

According to foreign experience standards, the anti-corrosion coating of the base material of general-purpose profiled steel plates (pit plates) should not be less than 350g/㎡ (Z35) hot-dip galvanized or 185 g/㎡ (AZ185) hot-dip aluminum zinc plated

As the minimum hot-dip galvanized layer for cold-rolled steel and floor slabs in building structures, the specification for Zinc/Galvanizing is 275 g/㎡ (Z27), and the requirement for exposed coastal components is 350 g/㎡ (Z35).

Galvalume steel Features:

 Thermal reflectivity:

The thermal reflectivity of aluminum zinc coated steel plate is very high, twice that of galvanized steel plate, and it is often used as a thermal insulation material.

Heat resistance:

Aluminum zinc alloy steel plate has good heat resistance and can withstand high temperatures of over 300 degrees Celsius, similar to the high-temperature oxidation resistance of aluminum plated steel plate. It is often used in chimney pipes, ovens, lighting fixtures, and fluorescent lampshades.
