Why does precipitation appear on the surface of hot-dip galvanized steel grating?

Steel grating plate is also called steel grating plate. The grating plate is made of flat steel arranged crosswise with horizontal bars at a certain distance and welded into a steel product with a square grid in the middle. It is mainly used for water treatment. Ditch cover plates, steel structure platform plates, steel ladder treads, etc. The crossbars are generally made of twisted square steel.
Hot-dip galvanized steel grating is also called hot-dip galvanized steel grating: it is a kind of steel grating. It melts zinc ingots at high temperature, puts in some auxiliary materials, and then immerses the metal structural parts in galvanizing. In the groove, a layer of zinc is attached to the metal components. The advantage of hot-dip galvanizing is its strong anti-corrosion ability and good adhesion and hardness of the galvanized layer. The weight of the product increases after galvanizing. The amount of zinc we often talk about is mainly for hot-dip galvanizing.
Steel gratings are generally made of carbon steel, and the surface is hot-dip galvanized to prevent oxidation. It can also be made of stainless steel. The steel grating plate has ventilation, lighting, heat dissipation, anti-skid, explosion-proof and other properties.

What’s the matter with precipitation on the surface of hot-dip galvanized steel grating?
1. Generally, before galvanizing, the surface of the product is not cleaned very thoroughly. However, the so-called surface content of the workpiece is actually the so-called oxide film, which continuously affects the zinc. The deposition is normal;
2. Secondly, the raw material (flat steel) used to make the product itself has a relatively high carbon content. However, it will definitely reduce the related potential. If acceleration occurs on the surface of the workpiece, then the efficiency of the current will definitely be will continue to decrease;
3. If the discharge state of the product is incorrect, and when the binding is too dense, all parts of the steel grating will be shielded and the coating will gradually become too thin. happened.
