Let Jiaxing MAXEA Hardware Manufacturer Co., Ltd tell you about the difference between hot galvanizing and ordinary galvanizing?
Hot-dip galvanizing, also known as hot-dip galvanizing, is to melt the zinc ingot at high temperature, put some auxiliary materials, and then immerse the metal structural parts into the galvanizing tank to make a layer of zinc adhere to the metal components. The advantage of hot dip galvanizing is that it has strong anti-corrosion ability, and the adhesion and hardness of the galvanized layer are better.
Cold plating is electroplating, that is, the zinc salt solution is electrolyzed to coat the plated parts. Generally, no heating is needed, and the amount of zinc is very small. It is easy to fall off in a humid environment.


About this single construction engineering bolt, I strongly recommend using hot-dip galvanizing. Hot-dip galvanizing is a chemical treatment and belongs to an electrochemical reaction.
Cold galvanizing is a physical treatment, only a layer of zinc is painted on the surface, so the zinc layer is easy to fall off. Hot dip galvanizing is mostly used in building construction.
The difference between galvanized products: hot-dip galvanized appearance is not as delicate and bright as cold-dip galvanized, but the thickness of hot-dip galvanized zinc layer is dozens of times that of cold-dip galvanized. The corrosion resistance is also dozens of times that of electro-galvanized.
