1、 Mechanical performance indicators

Firstly, the mechanical properties of hot-dip galvanized products. Mechanical performance can be defined as the product performance that can be confirmed through tensile testing, such as yield strength, tensile strength, elongation, n-value, r-value, and so on.

2、 Coating performance indicators

The most important performance of hot-dip galvanized products is the coating performance, mainly referring to the corrosion resistance and adhesion performance of the coating. Corrosion resistance includes resistance to salt spray and moisture, while coating adhesion refers to the product's resistance to coating cracking, peeling, powdering, and other properties during processing.

3、 Other performance indicators

No experiment can match the actual usage situation very well. Other important performance factors include surface quality, such as the surface quality of commonly known automotive and home appliance exterior panels. For the automotive industry, surface roughness control of steel plates is also very important. A few sentences cannot fully explain the definition of surface quality. It is best not to directly use it in different usage processes, but to verify it first. In addition, there are some explanations, such as the existence of edge cutting and non edge cutting for alloy products or ordinary hot-dip galvanized products. Non edge strip steel is allowed to have small zinc layer cracks and white edges at its edges.
