Product Description

Product Description

Galvalume steel coil is a type of steel coil that is coated with a mixture of aluminum, zinc, and silicon to provide enhanced corrosion resistance and durability.

Here are some common specifications associated with Galvalume steel coil:

Steel Substrate:

Galvalume steel coil is typically made from high-quality cold-rolled or hot-dip galvanized steel. The steel substrate provides the structural strength and formability to the coil.

Coating Composition:

The coating on Galvalume steel coil consists of a mixture of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This combination of metals provides excellent corrosion resistance and barrier protection.

Thickness:

Galvalume steel coil is available in various thicknesses, typically ranging from 0.12 to 1.5 millimeters (0.0047 to 0.059 inches). The thickness determines the strength and durability of the coil and can be chosen based on specific application requirements.

Width:

The width of Galvalume steel coil can vary depending on the manufacturer and specific product. Common widths range from around 600 to 1500 millimeters (23.6 to 59.1 inches). The width is chosen based on the intended application and manufacturing processes.

Coil Weight:

Galvalume steel coil is supplied in coil form and is typically available in different coil weights. The coil weight can vary depending on the thickness and width of the coil. Common coil weights range from a few hundred kilograms to several metric tons.

Surface Finish:

Galvalume steel coil is usually supplied with a regular spangle surface finish, which provides a crystalline pattern on the surface. However, it can also be available in other finishes such as minimized spangle or zero spangle based on specific requirements.

Coating Weight:

The weight of the aluminum-zinc-silicon coating on Galvalume steel coil is typically specified in terms of coating mass or coating thickness. The coating weight is measured in grams per square meter (g/m²) or ounces per square foot (oz/ft²). Common coating weights range from 70 to 180 g/m² (2.1 to 5.4 oz/ft²).

Paintability:

Galvalume steel coil can be further coated or painted to provide additional protection or achieve specific aesthetic requirements. The coil's surface is designed to be compatible with various paint systems, allowing for customization and color options.
