The difference between cold galvanizing and hot galvanizing for galvanized steel grating
The surface treatment methods are different: hot dip galvanizing is also called hot dip galvanizing. It melts the zinc ingot at high temperature, puts some auxiliary materials, and then immerses the metal structural parts in the galvanizing tank, so that a layer of zinc layer is attached to the metal components. It belongs to electrochemical reaction.
Generally, the zinc content of the hot-dip galvanized steel grating is about 70UM, the adhesion and hardness of the galvanized layer are good, and the corrosion resistance of the hot-dip galvanized steel grating is relatively good, which is generally suitable for outdoor use. "Cold plating" is "electroplating", that is, the zinc salt solution is electrolyzed to coat the plated parts. Generally speaking, there is no heating, and the amount of zinc on the galvanized parts is very small. The amount of zinc on the galvanized parts is only about 10 grams. It belongs to physical treatment, and it is easy to fall off in wet environment. The corrosion resistance of cold galvanized steel grating is not so good, and it is generally used indoors.
Color difference: generally, the color of hot-dip galvanized steel grating is bright and silvery white, while the color of electro galvanized steel grating is dark and dirty white.
The use time is different: the hot-dip galvanized steel grating can be used for about 30-40 years, while the cold galvanized steel grating is easy to rust and slowly corrode, so it can't be used for about 1-2 years
