Aluzinc Sheet |Aluminum and Zinc Steel Sheet

Aluzinc Sheet is a durable and versatile coated steel, which is a quality solution for projects with excellent corrosion resistance, durability, and cost-effectiveness, GNEE STEEL, as a professional coated steel factory, specializes in supplying premium GL steel coil, sheet that meets the international standards. In addition, we also have bending, stamping, punching, slitting, forming, and other nearby services. You are welcome to contact us.

What is Aluzinc Sheet? 

Aluzinc steel sheet - commonly referred to as Galvalume steel - is a premium alloy-coated product manufactured by hot-dip plating a cold-rolled steel substrate with a protective aluminum-zinc layer. The coating is composed of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon, forming a durable metallurgical bond that significantly enhances corrosion resistance and service life.

Price

Aluzinc steel sheet is generally priced between USD $600–$900 per tonne, depending on factors such as manufacturing process, coating weight, alloy layer thickness, sheet thickness, total order tonnage, surface finish, and any additional processing requirements.

Benefits of Aluzinc Steel Sheet (Galvalume)

🔹 Outstanding Corrosion Resistance
The aluminum-zinc alloy coating offers exceptional resistance to salt spray, humidity and chemical exposure - delivering 2–4 times higher corrosion performance than traditional galvanized steel, especially in coastal, industrial and high-humidity environments.

🔹 Superior Heat Resistance
The Aluzinc coating can withstand temperatures up to 600°F (315°C) without surface degradation, making it suitable for high-temperature applications and outdoor structures.

🔹 Lightweight Yet Strong
Aluzinc steel sheet is 20–30% lighter than galvanized steel while maintaining excellent tensile strength, reducing overall structural weight and lowering transportation and installation costs.

🔹 Excellent Mechanical Performance
With high fracture resistance and the ability to tolerate mechanical stress, Aluzinc steel performs reliably in forming, bending, and roll-forming applications.
