Hot dip galvanizing is a common coating for bolts, which has the characteristics of high cost-effectiveness and good appearance. But its anti-corrosion effect is average, and its anti-corrosion effect is relatively low in the coating. The pre tightening force of hot-dip galvanizing on the mid air center bolt is unstable, and it is generally used in riveting places where the load is not large.

Stainless steel bolts have excellent corrosion resistance, and their corrosion resistance in marine gas natural environments is better than other metal surface treatments. The cost of wastewater treatment in the production process of stainless steel is high, so they are not used in general natural environments. Chromium coating is relatively stable in air, not easy to fade or lose luster, and has high strength.

Hot dip coating is the process of external diffusion coating when zinc is heated to a liquid state. Its coating thickness is 10-15 μ m, andAll aluminum lantern shaped pop rivetsNot easy to control, but has good corrosion resistance, often used in engineering projects.

The metal surface treatment of the mid air center bolt is mainly for better corrosion resistance, and it combines color and overall personnel decoration design effects. Therefore, bolts generally need to be surface treated, and different surface treatments also need to consider environmental pollution issues. Each coating has a variety of coating thicknesses to apply different corrosion resistance testsExtra long rivets for automobilesApplied to different products.

For different products with different characteristics, it is necessary to carry out metal surface treatment that is consistent with the quality and potential. Otherwise, not only will it fail to meet the estimated requirements, but it will also continue to damage the product. Therefore, we need to develop appropriate solutions for the product based on our understanding of metal surface treatment.
