G300+AZ80 Galvalume Steel Coil

Galvalume Steel Coil · G300+AZ80 Structural Grade · 80 g/m² 55% Al-Zn Coating · AZ Coated · Custom Width / Slitting Available

Product Summary

G300+AZ80 Galvalume Steel Coil is a structural 55% aluminum-zinc alloy-coated steel coil on a G300 substrate, with a nominal coating mass of 80 g/m² (AZ80). The G300 structural grade provides consistent strength for building components, while the AZ80 coating offers standard corrosion protection.

This grade is supplied for roofing, cladding, purlins and structural building components where reliable strength and standard corrosion protection are required.

Differentiator: G300 structural substrate + AZ80 aluminum-zinc coating mass.

Supply capability: Order-based Supply — Available upon request / Custom supply. This listing is presented per the Order-based Supply classification; it is not packaged as standard in-stock material.
