Common specifications for 55% Aluzinc Galvalume Steel Coil:
Thickness range: 0.4 mm – 2.0 mm (commonly 0.6 mm, 0.8 mm, 1.0 mm)
Width: 1000 mm – 1250 mm (customizable)
Coating weight: AZ150 (150 g/㎡) recommended for exterior building applications; AZ100 (100 g/㎡) optional for interior applications.
Surface treatment: Commonly treated with fingerprint-resistant, anti-fingerprint, or passivation for easy installation and use.
Aluzinc Steel Coil is a corrosion-resistant metal material made from cold-rolled steel sheet as the base material, with a hot-dip aluminum-zinc alloy coating. The coating composition is approximately 55% aluminum, 43.4% zinc, and 1.6% silicon. It is widely used in construction, home appliances, automobiles, and industrial fields.
ASTM A792 Aluzinc Galvalume Steel Coil is a 55% aluminum-zinc alloy hot-dip coated steel sheet manufactured according to the American Society for Testing and Materials (ASTM) standard ASTM A792/A792M-25. It is widely used in construction, automotive, and home appliances.
AZ150 Aluzinc Galvalume Steel Coil is an alloy-coated steel sheet composed of 55% aluminum, 43% zinc, and 1.6% silicon, with a coating weight of 150 g/m² (total weight on both sides). It is widely used in construction, home appliances, automobiles, and many other fields.
Common grades and standards for AZ150 Aluzinc Galvalume Steel Coil:
– Cold forming steel: DC51D+AZ, DC52D+AZ, DC53D+AZ, DC54D+AZ
– Structural steel: S250GD+AZ, S300GD+AZ, S350GD+AZ, S550GD+AZ
– Coating designation: AZ (aluminum-zinc alloy coating)
– Recommended coating weight: 30/30, 40/40, …, 150/150 g/m² (AZ150 is 150 g/m²)
Galvalume steel coil, also known as Aluzinc Steel Coil, is composed of 55% aluminum, 43.4% zinc and 1.6% silicon by weight.
Compared with galvanized steel coils of the same thickness, Galvalume Steel Coils containing 55% aluminum-zinc alloy coating have better corrosion resistance when exposed to the same environment on both sides. 55% aluminum-zinc alloy coated Galvalume Steel Coil not only has good corrosion resistance, but its color-coated steel coil products have excellent adhesion and flexibility.
