Transformers work on the principle of electromagnetic induction. The transformer body is mainly composed of winding and iron core.

Hot-dip galvanizing was developed from the older hot-dip method. It has a history of 140 years since France applied hot-dip galvanizing to industry in 1836.

Color-coated coils are made of cold-rolled steel and galvanized steel as the base material. After continuous surface pretreatment, they are baked and cooled.

Electrolytic plate, also known as electrolytic galvanized plate, is a process that uses electrolysis to form a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of the workpiece.

Galvanized steel coils are mainly produced by the continuous galvanizing process, that is, the rolled steel plates are continuously immersed in a plating bath containing molten zinc to make galvanized steel coils.

Improve the surface flatness of galvanized sheets. After smoothing, the flatness of the galvanized sheet has been improved to a certain extent.
