Galvalume steel (GL) coil/sheet
Induction: Galvalume steel is a carbon steel coated with an aluminum-zinc alloy. The continuous hot dip process combines the corrosion and high temperature resistance of aluminum with the formability and electrochemical protection of zinc.

Surface Treatment
Type |
Description |
Chromate passivation |
Chromate passivation reduces black rust during transport or storage |
Oiled |
Oiled surface treatment can reduce black rust, but it cannot be used for subsequent processing of rolling and stamping lubricants. |
Chromate passivation & oiled |
Chromate passivation and oiled surface treatment can effectively reduce black rust. |
Anti-finger printing |
Anti-fingerprint surface treatment can help reduce black rust. |
No treatment |
No surface treatment, the steel coil is prone to black rust. |
Characteristic
Smooth surface and uniform gloss |
More corrosion resistance and heat reflectivity |
Anti-fingerprint coating makes the surface look more beautiful |
High temperature resistance and formability |
Wider thickness range with tight tolerances |
Easy for a variety of painting applications |
