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.
