The difference between hot dip galvanizing and cold galvanizing
Hot-dip galvanizing refers to melting zinc at high temperature, adding appropriate amount of auxiliary materials, so that there is a zinc layer on the metal components. What is the difference between hot-dip galvanizing and cold galvanizing?   1. What is the difference between hot-dip galvanizing and cold galvanizing 1. The principle is different. Hot-dip galvanizing involves dipping steel into molten zinc to coat the metal on the part, while cold galvanizing uses electrochemical principles to prevent corrosion. 2. Differences in corrosion resistance. Hot-dip galvanizing is a chemical treatment, which is an electrochemical reaction. Cold galvanizing is a physical treatment. A layer of zinc on the surface layer is easy to fall off, so hot-dip galvanizing is more corrosion-resistant than cold galvanizing. 3. Different thickness. The thickness of hot-dip galvanizing can reach more than 10 microns, while cold galvanizing is thinner, about 3 microns to 5 microns. 4, the price and practicality are different. Cold galvanizing is cheaper than hot galvanizing, but hot galvanizing is more practical than cold galvanizing.   What are the applications of hot-dip galvanizing?   Its zinc layer is relatively thick and the process is relatively simple, and it is suitable for anti-corrosion of steel products in highly corrosive places such as strong acid and alkali. Its surface is rough and the decorative effect is relatively poor, so it is mainly used for the protection of steel components. Nowadays, semi-finished products such as galvanized steel sheets, steel wires and steel pipes on the market all use this process. This process is also widely used in industries such as electric power, transportation, petroleum and household appliances, so it has a relatively large range of use.   What are the applications of cold galvanizing? It can be used in civil engineering, such as steel bars, guardrails, etc., and can also be used in construction, such as handrails, scaffolding, three-dimensional parking lots, etc. It can also be used in electric power such as iron poles and transformer racks, and can also be used in shipbuilding industries such as buoys, locks, and piping.
