Hot-dip galvanizing (galvanizing), also known as hot-dip galvanizing and hot-dip galvanizing, is an effective method of metal anti-corrosion, mainly used in metal structural facilities in various industries. It is to immerse the rust-removed steel parts in a molten zinc solution at about 500 ° C, so that the surface of the steel parts adheres to the zinc layer, so as to achieve the purpose of anti-corrosion.
Hot-dip galvanizing process: finished product pickling - water washing - adding plating solution - drying - rack plating - cooling - chemical chemical - cleaning - polishing - hot-dip galvanizing is completed.
Hot-dip galvanizing is developed from the older hot-dip galvanizing method. It has a history of more than 170 years since the application of hot-dip galvanizing to the industry in France in 1836. In the past three decades, with the rapid development of cold-rolled strip, the hot-dip galvanizing industry has developed on a large scale.
