Hot-dip galvanizing is a chemical treatment, which is an electrochemical reaction. Cold galvanizing is a physical treatment, only a layer of zinc is brushed on the surface, so the zinc layer is easy to fall off, and hot-dip galvanizing is often used in construction.
Cold galvanizing is electro-galvanizing, only 10-50g/m2, and its corrosion resistance is much different than that of hot-dip galvanizing. The price of electro-galvanizing is relatively cheap.
Hot-dip galvanizing is the galvanizing of the surface of the steel body under the condition of hot-dip. Require.
What is cold galvanized steel grating?
“Cold plating” is “electroplating”, that is, the zinc salt solution is electrolyzed to coat the plated parts. Generally speaking, no heating is required, and the amount of zinc applied is very small. It is easy to fall off in a humid environment. Hot-dip galvanizing is also called hot-dip plating. Zinc, cold galvanizing is to melt zinc ingots at high temperature, put some auxiliary materials, and then immerse the metal structural parts into the galvanizing tank, so that a layer of zinc layer is attached to the metal components. The advantage of hot-dip galvanizing lies in its Strong anti-corrosion ability, good adhesion and hardness of galvanized layer.
What is the difference between hot dip galvanized steel grating and cold galvanized steel grating?
Regarding the distinction between hot-dip galvanized steel grating and cold-galvanized steel grating, color, thickness and price are mainly distinguished from three aspects.
Steel grating hot galvanized and cold galvanized color difference:
Let’s first look at the color of the surface of the steel grating. Generally, the color of the hot-dip galvanized steel grating is relatively bright, which belongs to hi silver gray. Cold galvanizing is also called electroplating. The color of the electroplating is darker and the color is dirty and white.
The difference between hot-dip galvanizing and cold galvanizing of steel grating:
Secondly, look at the thickness of the galvanized layer. The amount of zinc applied to the general hot-dip galvanized steel grating is about 70um, while the amount of zinc applied to the electro-galvanized steel is only about 10 grams.
The price difference between hot-dip galvanizing and cold galvanizing of steel grating:
The price of general hot-dip galvanized steel grating is higher than that of cold galvanized steel grating.
