１．Product Overview

DX53D Pre-Painted Galvalume Steel Coil combines the corrosion resistance of aluminum-zinc alloy coating with the decorative and protective benefits of a painted surface. It is widely used in construction, automotive, electrical appliance, and industrial manufacturing sectors where long service life and attractive appearance are required.

The product offers excellent formability, coating adhesion, and weather resistance, making it suitable for roofing panels, wall systems, appliance housings, and architectural applications.

２．Technical Solution

The steel substrate is coated with an aluminum-zinc alloy layer according to ASTM A792, JIS G3321, or EN 10346 standards. The coating provides barrier protection from aluminum and sacrificial protection from zinc. Additional surface treatments such as chromating, oiling, and anti-fingerprint coatings improve durability and storage performance.

The material can be further processed into pre-painted products while maintaining excellent adhesion and corrosion resistance.
