Z275 Galvanized Coil Description
The galvanized steel coil Z275 is a double-sided galvanized carbon steel sheet. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc. This continuous hot-dip plating or also known as electro-galvanizing is the main process that these carbon steel sheets must go through to produce coils and galvanized sheets. The process consists of applying zinc by electrolytic treatment. After the sheet is subjected to this treatment, a layer of zinc is adhered to the base metal through the iron and zinc bonding layer.
Galvanizing is a well-known and effective method to add a protective layer to prevent the exposed steel from being corroded by natural elements. Zinc not only acts as a barrier between the environment and the steel, but it also decomposes first to protect the underlying steel and extend its service life.
Scope of Application
Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
