Product Description
S350GD+AZ Galvalume Steel Coil 0.12-2.0mm Thickness For Building Roofing
GL-55% aluminum-zinc coated galvalume steel coil, also known as Alu-Zinc or Al-An coil, is produced by hot-dipping a cold-rolled steel base with a 55% aluminum, 43.5% zinc, and 1.6% silicon alloy. This coating combines aluminum's long-lasting barrier protection and high durability with zinc's electrochemical sacrificial properties. The result is a corrosion-resistant material ideal for roofing, industrial, and automotive applications.

Applications
Galvalume steel coil is widely used across multiple industries due to its excellent corrosion resistance, durability, and formability. Common applications include:
- Shutter Door: Ideal for rolling shutter doors in commercial and industrial buildings, offering strength and weather resistance.
- Building Roof: Used for residential and industrial roofing, providing long-lasting protection against sun, rain, and snow.
- Fence: Suitable for outdoor fencing and barriers, resisting rust and reducing maintenance over time.
- Automotive: Applied in vehicle body parts, undercarriage components, and structural elements for corrosion protection.
- Vent Duct: Commonly used in HVAC ductwork and ventilation systems, offering durability and moisture resistance.
- Home Appliance: Found in refrigerator casings, air conditioner housings, and washing machine panels for both protection and aesthetics.

Packaging & Shipping
Each galvalume steel coil is wrapped with a three-layer protection system for safe shipping: moisture-proof paper, heavy-duty PE film, and steel strapping (normally 3–5 tons per bundle, with options for custom loads). We work with trusted logistics providers to offer FCL, LCL, and breakbulk shipping. Delivery is fully trackable and typically takes 2 to 5 weeks to reach most global destinations.
