Product Specification

0.45mm AZ80 Anti-Finger Galvalume Steel Coil for Roofing, Cladding and Industrial Applications

１．Product Overview

This 0.45mm Galvalume Steel Coil is manufactured according to EN 10346 standards and features an aluminum-zinc alloy coating designed to provide long-term corrosion resistance and durability. The product combines a high-quality cold rolled steel substrate with an AZ coating and anti-finger treatment for improved surface performance and appearance.

It is widely used in roofing systems, wall cladding, industrial buildings, household appliances, transportation equipment, and fabricated metal components.

２．Technical Solution

The steel substrate is continuously hot-dip coated with an aluminum-zinc alloy layer containing approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This coating structure offers both barrier protection and sacrificial corrosion resistance.

Anti-finger treatment provides additional surface protection, reduces fingerprints during handling, and improves storage performance during transportation and fabrication.

３．Specifications

４．Application
