Galvalume

Aluminum-Zinc Coated Steel(commonly known as Galvalume, a trademarked name) is a corrosion-resistant material produced by hot-dip coating a steel substrate with an aluminum-zinc alloy (typically 55% aluminum, 43.4% zinc, and 1.6% silicon). This coating combines aluminum's heat resistance and barrier protection with zinc’s sacrificial anode properties, offering dual anti-corrosion mechanisms. Its distinctive silver-white metallic sheen and spangled surface pattern make it ideal for roofing, automotive components, and industrial applications.l

Anti-Finger print & Without AFP

Common Features

Alloy Coating: Aluzinc layer (e.g., AZ150g/㎡) provides superior corrosion resistance.

Heat Resistance: Both withstand temperatures up to 300℃ for outdoor/industrial use.

Differences

Surface Treatment: Oil,Chromated,Chromium-free passivation,anti-finger print

Applications: Aluzinc is ideal for construction and infrastructure; anti-fingerprint suits high-cleanliness industries like electronics and medical devices.
