Galvanized steel sheets are coated using two methods: hot-dip galvanizing and electrogalvanizing.

Hot-dip galvanizing involves immersing metal products in molten zinc, depositing a relatively thick zinc layer on their surface. This layer typically exceeds 35 microns and can reach up to 200 microns. It is widely used in construction, transportation, and power generation, including in metal structures like transmission towers and bridges.

Electrogalvanizing uses electrolysis to form a uniform, dense, and well-bonded zinc coating on the surface of metal parts. The layer is relatively thin, approximately 5-15 microns, resulting in a smooth and even surface. Electrogalvanizing is commonly used in the manufacture of automotive and appliance parts, where coating performance and surface finish are crucial.

Galvanized sheet thickness typically ranges from 0.15 to 3.0 mm, and widths typically range from 700 to 1500 mm, with custom lengths available.

Galvanized sheet is widely used in the construction industry for roofs, walls, ventilation ducts, household hardware, automobile manufacturing, and home appliance production. It is an indispensable basic protective material for both industrial and residential applications.
