55% Aluminum Coating S550GD Grade AZ150 Galvalume Steel Coil Aluzinc Steel Coil for Roofing and Construction

Also known as galvalume or zincalume steel, aluzinc steel is a form of cold-rolled galvanized steel with a metal coating composed of 55% aluminum, 43% zinc, and 1.6% silicon. Its unique composition gives aluzinc steel distinctive features by combining the physical protection and high durability of aluminum with the electrochemical protection of zinc.

Aluzinc is the world's fastest-growing metallic coating. This is due to the combined strength, formability, and recyclability of steel with the proven long-term anti-corrosion performance of the AI-Zn alloy coating. This combination results in an economical product with superior eco-friendliness attributes of durability, recyclability, energy efficiency, and scarce resource utilization.

Aluzinc has a clean, natural, and bright silvery surface. The surface includes small spangles that give it a lustrous and striking appearance as light conditions change.

We support customization of color-coated coils of various specifications and uses.

• Corrosion Resistance: Aluzinc steel coils are more corrosion-resistant than standard galvanized steel coils. The aluminum in the coating acts as a protective barrier, while the zinc acts as a sacrificial layer, adding an extra layer of corrosion resistance.
• High Heat Resistance: Aluzinc steel coils have extremely high heat resistance, allowing them to survive high temperatures without major structural changes.
• Formability and Machinability: Aluzinc steel coils have extremely high formability and are easily formed without cracking or breaking. This property makes them suitable for a variety of production procedures, such as bending, roll forming, and stamping.
• Aesthetic Versatility: With a smooth, shiny surface, Aluzinc steel coils offer aesthetic versatility. They can be coated in a variety of colors, coatings, and textures, offering unique solutions to match architectural designs and personal tastes.
