Equipped with shearing, slitting, and roll forming equipment, we can supply products in coil, sheet, and strip forms.
AZ30–AZ150 Aluzinc Steel, widely known in the industry as Galvalume, features a premium aluminum-zinc alloy coating (“AZ”). The numerical suffix (such as 30, 50, 75, 100, 120, or 150) represents the total coating weight across both sides, measured in g/m². Simply put: the higher the number, the thicker the coating, resulting in superior corrosion resistance and lasting protection. 1mm Aluminium Sheet S350GD+Z

The Advantage: High-temperature tolerance and robust structural integrity.
Applications: Mufflers, exhaust pipes, fuel tanks, shipping container side panels, and truck cargo compartment partitions.
Q1: What is the difference between Aluzinc (Galvalume) and regular Galvanized Steel?
A: The main difference lies in the coating. Regular galvanized steel has a 100% zinc coating, while Aluzinc (Galvalume) features an alloy coating of 55% aluminum, 43.4% zinc, and 1.6% silicon. This unique composition gives Aluzinc superior corrosion resistance (up to 2-6 times longer than galvanized steel) and excellent heat reflectivity, making it ideal for roofing and outdoor applications.
Q2: What does “AZ30 to AZ150” mean, and how should I choose?
A: “AZ” stands for the Aluminum-Zinc coating, and the number indicates the total coating weight in grams per square meter (g/m²) across both sides of the steel.
AZ30 – AZ50: Suitable for general indoor use or mild environments.
AZ75 – AZ100: Great for standard outdoor construction and appliances.
AZ150: Highly recommended for harsh environments, coastal areas, or industrial zones requiring maximum corrosion protection.
Q3: Can I customize the dimensions, thickness, and surface treatment?
A: Yes! At Bomis Steel, we offer fully customizable solutions. We can manufacture Aluzinc steel coils and sheets with thicknesses ranging from 0.13mm to 4.0mm and widths up to 1500mm. We also provide various surface treatments, including Anti-Fingerprint (AFP), chromated, and oiled finishes to meet your specific manufacturing requirements.
Q4: What is your Minimum Order Quantity (MOQ) and typical delivery time?
A: Our standard MOQ is 18 metric tons (equivalent to one standard 20ft shipping container). For regular specifications, our lead time is typically 15 to 30 days after receiving the deposit, ensuring you get your materials on schedule.
