DX51D G60 Galvalume Steel Coil with Anti-Finger Treatment for Construction and Appliance Applications

１．Product Overview

DX51D G60 Galvalume Steel Coil is manufactured according to ASTM A792, JIS G3321, and EN 10346 standards. The steel substrate is coated with an aluminum-zinc alloy layer that combines excellent corrosion resistance with long-term durability. Anti-finger treatment improves surface cleanliness and handling performance during fabrication and installation.

The product is widely used in construction, home appliances, transportation equipment, industrial machinery, and furniture manufacturing where corrosion protection and appearance consistency are important.

２．Technical Solution

The steel coil is continuously hot-dip coated with an aluminum-zinc alloy consisting of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon.

This coating structure provides both barrier protection and sacrificial corrosion resistance.

Additional passivation, chromating, oiling, or anti-finger treatment can be applied to enhance storage stability, processing performance, and surface durability.

３．Specifications

４．Application
