Galvanized steel sheet has good anticorrosive effect, so it is widely used in industry. The galvanized steel sheet has a smooth galvanized surface and can be used for a long time in order to prevent rust. As a relatively primary semi-finished product for the production of metal products, galvanizing is widely known. Galvanizing is also divided into hot-dip galvanizing and cold-dip galvanizing. The following explains the difference between these two types of galvanizing, from the production process to the production process, one Layer by layer shows you the difference between the two processing and production links, so that everyone can better understand the difference between the two galvanized sheets.
Hot-dip galvanizing is also called hot-dip galvanizing. It is to melt the zinc ingot at high temperature and put some auxiliary materials, and then immerse the metal structural parts in the galvanizing tank so that a layer of zinc can be attached. The advantage of hot dip galvanizing is that it has strong anti-corrosion ability. The adhesion and hardness of the galvanized layer of the building reinforcement project are good. Hot dip galvanizing is a chemical treatment that belongs to the electrochemical reaction. Hot dip galvanizing is mostly used in construction.
"Cold plating" or "electroplating" means that the zinc salt solution is plated on the plated parts by electrolysis. Generally speaking, the amount of zinc used in construction engineering reinforcement without heating is very rare and it is easy to fall off in a humid environment. Cold galvanizing is a physical treatment, just brush a layer of zinc on the surface, so the zinc layer is easy to fall off.

Cold galvanized is electrogalvanized with only 10-50g/m2, its own corrosion resistance is much worse than hot dip galvanized. The price of electro-galvanized steel sheet used for building reinforcement is relatively cheap. Hot-dip galvanizing is that the steel body is galvanized on the surface under the condition of hot dipping. It has strong adhesion and is not easy to fall off. Although the hot-dip galvanized pipe also exhibits corrosion, it can meet the technical and hygienic requirements in a long period.
