Product Description

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel

(aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon

olidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary

crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars,

and its base color is silver white. The special coating structure makes it have excellent corrosion resistance.

The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used

in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has

good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.

Characteristics of Galvalume Steel

1.Machinability

It can satisfy the processing requirements of rolling, coiling and others processes alike.

2.Thermal resistance

Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however,

Galvalume steel plate cansustain the environment at 315℃ for long time.

3.High reflectivity

Reflection ability of heat and light is twice as much as those ofhot-dip zinc steel sheet, and its reflectivity is

more than 0.70, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction

materials of saving energy.

4.Resistance to corrosion

Al-Zn coated steel sheet has better performance in corrosion resistance than GI sheet of the same thickness

and its service life is 2-6 times longer than general GI sheet.
