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
Coating Weight	70 – 280 GSM
Most Preferred Grade	AZ150

Key Features

• Consistent chemical composition
• Excellent surface finish
• Long service life

Technical Properties

• Corrosion & Heat Resistance: Up to 6× better than zinc-coated steel; excellent edge protection; high reflectivity
• Weldability: Similar to galvanized steel, requires correct settings
• Formability: Can be rolled, bent, or deep-drawn; depends on base metal grade
• Surface Finish Options: Skin-passed, Regular Spangle (on request)

Applications

• Roofing & construction
• HVAC systems
• Automotive components
• Electrical enclosures
• Appliances & industrial panels

Aluzinc Steel is a high-performance coated steel solution that combines the strength of steel with the superior corrosion resistance of an aluminium–zinc alloy coating. Offering excellent durability, heat reflectivity, and long service life, it is ideal for demanding environments and diverse industrial applications. With a wide range of thicknesses, coating options, and grades available, Aluzinc Steel provides a cost-effective and reliable alternative to conventional galvanized steel for construction, automotive, and manufacturing needs.
