Converting Coating Thickness to Weight for Aluminized Steel

How to Convert Coating Thickness (μm) of Aluminum Plate to Coating Weight (g/㎡)

To convert the coating thickness (μm) of an aluminum plate to coating weight (g/㎡), it’s essential to understand the coating thickness first. Here are common zinc coating thicknesses:

• Z08: 0.017mm (17μm)
• Z12: 0.026mm (26μm)
• Z18: 0.034mm (34μm)
• Z22: 0.043mm (43μm)
• Z27: 0.054mm (54μm)

These measurements, originally in millimeters, are converted to microns (μm) to better understand the coating thickness.

Conversion Formula

To calculate the coating weight (g/㎡), use the following formula:

Coating weight (g/㎡) = Coating thickness (mm) × 7.85

This formula is based on the density of the coating material, which is typically 7.85 g/cm³ for pure aluminum, and is similar to the coating found in aluminized steel products. If you are an aluminized steel supplier, understanding this conversion is crucial to determine the correct coating weight for products like aluminized steel sheets.

Example Calculations

1. For Z08 coating (0.017mm thickness):
   0.017 × 7.85 = 0.13345 g/㎡

2. For Z12 coating (0.026mm thickness):
   0.026 × 7.85 = 0.2041 g/㎡

3. For Z18 coating (0.034mm thickness):
   Calculation follows the same process.

This method can be used to convert any coating thickness (μm) to the corresponding coating weight (g/㎡), whether for aluminum or aluminized steel products. When buying aluminized steel, keep in mind that aluminized steel prices can vary depending on the coating thickness and the amount required. As a trusted aluminized steel supplier, it’s important to ensure accurate conversion for pricing and inventory management.
