Anti-corrosion galvanizing is a metal structures coating process by applying zinc which allows to protect the product against corrosion. Galvanizing is carried out in different ways. The coating method selected depends on the condition of the product and the necessary protection layer properties required.
There are different types of galvanizing (hot-dip galvanizing, thermo-diffusion zinc coating, Electrolytic zincing, cold galvanizing) each have their own characteristics.
«Chemical Cleaning Technology» LLC renders galvanizing service in several ways.
1. Hot-dip galvanizing
Hot-dip galvanizing is considered as one of the most reliable, economical and therefore common methods of steel corrosion protection. The hot-dip galvanizing method is advisable for large structures, pipes, beams, fittings and sheets.
The zinc layer thickness varies from 100 to 280 microns
2. Electro zincing
The zinc dissolves in the electrolysis process and its ions with an electro-positive potential settle on the base metal surface with the formation of a layer thickness of 5 to 25 microns, with high accuracy repeating the contours of the product. The surface layer obtained by galvanizing on the finished product is uniform, solid and strongly bound to the base metal.
Electro zincing technology is the most widespread in the fasteners, nails, wire and other metal-ware production.
