What are the advantages of Zinc-plated screws?

There are two kinds of electrically galvanized screws. 

The first is hot-dip galvanized bolt; The second is cold galvanized bolt, commonly used galvanized yellow bolt; 

The main function of these two kinds of bolts is rust prevention. The rust prevention ability of the first kind of bolt is much stronger than that of the second kind. It is suitable for smog areas or coastal areas. Galvanized screws have anti-corrosion effect. Advantages of galvanized screws:

1, low processing cost: the cost of hot dip galvanized rust prevention is lower than that of other paint coating;

2, durable: in the suburban environment, the standard hot dip galvanized rust prevention thickness can be maintained for more than 50 years without repair.

Hot-dip galvanized screws, also known as hot-dip galvanized bolts and hot-dip galvanized bolts, are an effective way of metal corrosion prevention, mainly used in various industries of metal structure facilities. Is to remove rust after the bolt immersed in 500℃ melting zinc liquid, so that the screw surface attached zinc layer, so as to play the purpose of anti-corrosion.
