Why are bolts hot-dip galvanized?

Edit:Qingdao Haorui Steel Products Co., Ltd.UpDate:2021-12-17

Hot dip galvanized boltsIt is a useful metal anti-corrosion method, mainly used in metal structural equipment in various industries. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ℃, so that the surface of the steel parts is attached with a zinc layer, so as to achieve the purpose of anti-corrosion.
Cold galvanizing, generally speaking, does not need to be heated, and the amount of galvanizing is very small. This kind of galvanized parts simply falls off in a humid environment.

It can be seen that the effect of hot-dip galvanizing is better than that of cold galvanizing, so hot-dip galvanizing is used for bolts.
