Hot dip galvanizing is an effective method of metal corrosion prevention, mainly used on metal structural facilities in various industries. It is to immerse the rust removed steel components into a molten zinc solution at around 500 ℃, so that a zinc layer adheres to the surface of the steel components, thereby achieving the purpose of corrosion prevention. The galvanized layer is relatively firm and cold galvanized. Generally speaking, it does not require heating and has a small amount of galvanizing. This type of galvanized part is prone to detachment when exposed to humid environments. 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.
