Aluzinc Steel

We are widely recognized for supplying premium-quality Aluzinc Steel, a high-performance material engineered for superior durability and long-term corrosion protection. Produced through the Hot-Dip Aluminium-Zinc coating process, it features an Aluminium-Zinc-Silicon alloy coating for exceptional corrosion resistance, high reflectivity, and uniform finish.

Types of Aluzinc Steel

Type 1 – 55% Aluminium, 45% Zinc
High corrosion resistance and heat reflection. Ideal for harsh environments.

Type 2 – 45% Aluminium, 55% Zinc
Slightly lower heat & corrosion resistance than Type 1, economical, still superior to galvanized steel.

Type Comparison

Type	Composition	Advantages	Cost
Type 1	55% Alu / 45% Zinc	Excellent corrosion & heat resistance	Higher
Type 2	45% Alu / 55% Zinc	Good performance, superior to GI	Lower

Available Range

Thickness	0.25 – 3.00 mm
Width	Up to 1500 mm
