How To Identify Steel Grid Plate Is Cold Plating Or Hot Plating

Cold galvanized steel grid plate: Cold galvanized than ordinary physical spraying treatment, zinc layer in the steel plate surface is not easy fixed, cold is also called the plating electroplating zinc salt solution by electrolysis, namely to plating pieces of the coating, usually without heating, the amount of zinc rarely if there is a high temperature, moisture, rain, it is easy to cause the zinc layer on the surface of the steel plate, flat surface, then aggravate corrosion of steel case board itself. From the quality of zinc layer, cold galvanized galvanized layer is not very uniform. In terms of color, the color of cold plated steel grid plate is dark and dirty white

Hot dip galvanized steel grid: hot dip galvanized zinc layer is very firm penetration in the surface of the steel grid, strong adhesion, is not easy to fall off. In some high temperature, acid base environment can be used for a long time. Although the appearance of hot dip galvanized is not fine and bright cold galvanized, but the thickness of zinc layer hot dip galvanized is dozens of times of cold galvanized. Corrosion resistance is also dozens of times that of electrogalvanizing. The amount of zinc on the general hot-dip galvanized steel grid plate is about 70um, and the amount of zinc on the electric galvanized steel plate is only about 10 grams, and the color is relatively bright, silver white. Hot dip galvanizing has strong anticorrosion ability and good adhesion and hardness of galvanized layer. Hot dip galvanizing is a chemical treatment, belonging to electrochemical reaction.

We strongly recommend that you choose hot dip galvanized steel grid. Because hot dip galvanized although the price is higher than ordinary cold galvanized, but the service life is not cold galvanized can be comparable.
