Full Hard Anti-Fingerprint Galvalume Steel is an advanced composite metal material that combines high strength, corrosion resistance, and easy cleaning. It features an aluminum-zinc alloy coating on a high-strength, hardened substrate and is coated with an anti-fingerprint coating. It is widely used in demanding applications such as building structures, high-end home appliances, and industrial equipment.
Advantages – Full Hard Anti-Fingerprint Galvalume Steel
Full Hard Anti-Fingerprint Galvalume Steel overcomes the shortcomings of ordinary GL steel, such as insufficient strength and susceptibility to staining, providing a high-end solution for high-strength corrosion protection.
- High Strength: The fully hard substrate offers superior structural rigidity, 2-3 times that of ordinary soft-state aluminized zinc-plated steel.
- Superior Corrosion Resistance: Aluminum, zinc, and silicon alloys provide protection, while the fingerprint-resistant coating offers additional chemical protection, resulting in corrosion resistance 2-4 times that of ordinary galvanized steel and an ultra-long service life.
- Heat Reflection Resistance: Reflects over 80% of solar radiation heat and withstands temperatures up to 315°C.
- Clean and Aesthetically Pleasing: The bright silver matte surface with its fingerprint-resistant coating effectively prevents fingerprints and sweat residue, making it easy to clean and maintain.
Full Hard Anti-Fingerprint Galvalume Steel Structure
Full Hard Anti-Fingerprint Galvalume Steel employs a “composite structure design,” using fully hardened cold-rolled low-carbon steel as the substrate, plated with a 55%Al + 43.5%Zn + 1.5%Si alloy coating, and coated with a fingerprint-resistant coating. The layers are tightly bonded, achieving an adhesion level of 0 (no peeling in the cross-cut test), thus avoiding quality problems such as delamination and blistering.
