What is the role of galvanized screws

What is the role of galvanized screws

What is the role of galvanized screws? Most of the general screw surface treatment is for electroplating, such as galvanized, nickel plating, chrome plating, blackening, etc., then what is the role of galvanized screws?

First of all, let’s first understand the zinc: zinc is a metal element, it is not easy to rust in the natural environment, galvanized on the screw can inhibit the rust on the screw surface, galvanized screw can lift the corrosion resistance of the screw, to prevent the screw from being corroded during use. The advantages of galvanized screws have the following three points:

First, imitation screw corrosion: zinc is a kind of metal that is not easy to rust, plating zinc on the screw can imitate the screw surface rust, reduce the corrosion rate of the screw.

Second, improve the strength of the screw: zinc can improve the strength of the screw, because zinc can increase the hardness and resistance of the screw surface.

Third, extend the service life of the screw: zinc plating on the screw can extend the service life of the screw and reduce the wear and break rate of the screw.

Therefore, galvanized screws have become a common process, not only improving the corrosion resistance of screws, but also extending the service life of screws.
