Summary of Zinc Layer Thickness Specifications for Metal Wire Classes

This document provides detailed specifications for zinc coating thickness on metal wires, categorized by wire diameter and class type. The data is presented in a tabular format showing the minimum zinc coating mass (in grams per square meter) required for each wire diameter range across four classes: Class A, Class B, Class C, and Class D.

1. Zinc Coating Thickness Specifications

The table specifies the zinc coating mass (g/m²) for wire diameters ranging from 0.20 mm to 10.00 mm. The coating requirements vary by class, with Class A generally requiring the highest zinc mass and Class D the lowest. The classes likely correspond to different quality or corrosion resistance standards.

Key Points:

• Wire diameter ranges are segmented from 0.20-0.24 mm up to 8.20-10.00 mm.
• Class A zinc coating ranges from 30 g/m² for the smallest diameter to 300 g/m² for the largest.
• Class B zinc coating ranges from 20 g/m² to 150 g/m², generally lower than Class A.
• Class C zinc coating ranges from 20 g/m² to 110 g/m².
• Class D zinc coating ranges from 15 g/m² to 70 g/m², the lowest among the classes.
• For diameters above 5.20 mm, data for Class D is not provided.

3. Interpretation and Usage Recommendations

The zinc coating thickness is critical for corrosion resistance and durability of metal wires. Selecting the appropriate class and zinc mass depends on the intended application environment and required lifespan. Higher classes (e.g., Class A) are suitable for more demanding conditions.

Users should ensure compliance with these specifications to maintain product quality and performance.
