Product type
Galvalume steel coil is a type of coated steel product that combines the properties of aluminum and zinc to provide enhanced corrosion resistance. It typically consists of a cold-rolled steel substrate coated with an alloy of approximately 55% aluminum and 43.5% zinc, with a small percentage of silicon. This unique coating offers superior durability and longevity, making it suitable for various applications in harsh environments.
| Coating weight | Typically ranges from 30 to 200 g/m² |
| Thickness | Commonly available from 0.30 mm to 2.0 mm |
| Width | Standard widths range from 600 mm to 1500 mm |
| Yield strength | Usually between 250 MPa and 450 MPa |
| Finish | Available in both matte and glossy finishes |
When selecting Galvalume steel coil, consider the specific application requirements such as coating weight, thickness, and width. It is also important to specify the desired yield strength and finish. Buyers should inquire about certifications and standards that may apply to their industry, as well as any specific tolerances needed for their project. Quantities should be clearly defined to ensure accurate pricing and availability.
