Surface Treatment

Plating and surface treatment


The choice of plating and surface treatment depends on the application of the product. It is improve anticorrosion resistance and uniform surface, enhance surface hardness or decorate.


Zinc plating: Zinc is an inexpensive and easy-to-plate metal that is widely used to protect steel parts, especially to prevent atmospheric corrosion and to be used for decoration.


Nickel plating: used to improve the hardness of the material, while making it more corrosion.


Zinc Nickel Plating: Widely used in the fasteners industry for the surface treatment of steel and brass parts.


Phosphate: The torque-pretension consistency is very good, ensuring that the desired fastening requirements of the design are met during assembly. And it is to avoid hydrogen embrittlement problems.


Dacromet: Torque - pre-tightening consistency is very good, used for high strength fasteners requiring high corrosion protection.
