G60 Galvalume Steel Coil Az150 0.43mm 29 26 Gauge Aluminum-Zinc
Alloy Coated Steel Coil Roll
Aluminum-Zinc Alloy Coated Steel Product Introduction
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 solidified 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 Aluminum-Zinc Alloy Coated Steel:
1.Machinability
Galvalume Steel Coil 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 Coil 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.
