Aluminum-Zinc Alloy Coated Steel sheet Coils Product Information
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,43.5% zinc and 1.5% silicon solidified at 600℃.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℃.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.

Aluminum-Zinc Alloy Coated Steel sheet Coils Characteristics
1.Heat reflectivity:
The heat reflectivity of galvalume coil is very high, twice that of galvanized steel coil. People often use it as heat insulation material.
2. Heat resistance:
Galvalume steel coil has good heat resistance and can withstand high temperatures of more than 300 degrees celsius. It is very similar to the high-temperature oxidation resistance of galvalume steel coil. It is often used in chimney pipes, ovens, luminaires and fluorescent lampshades.
3.Corrosion resistance:
The corrosion resistance of galvalume steel coils is mainly due to the protective function of aluminum. When zinc is worn, aluminum forms a dense layer of aluminum oxide, preventing corrosion-resistant substances from further corroding the interior.
Antifinger/Non-Antifinger Surface of Aluminum-Zinc Alloy Coated Steel sheet Coils
Galvalume steel sheets can be divided into anti-finger(AFP) and Non-antifungal.
Anti-finger includes color anti-finger and colorless anti-finger.
Anti-fingerprint refers to coating a layer of anti-fingerprint liquid on the surface of a galvalume steel coil to prevent oxidation. Since human sweat and aluminized zinc are easily oxidized, a layer of anti-fingerprint liquid is applied to increase the service life of the Galvalume steel sheet.
