Zinc plating or electro galvanizing process

This galvanizing process is carried out cold. Steel materials are electric coated with a thin layer of zinc. This layer is usually 8 to 12 microns and can reach thicknesses of 30 microns. The difference with hot-dip galvanizing is thicknesses and parts deforming due to hot-dip galvanizing temperatures. The layer thickness is proportional to the duration over time of the materials, without the appearance of red corrosion. After electrolytic galvanizing, we apply a final finish, this process is known as passivation. Passivation varies depending on color and corrosion resistance. We carry out electro galvanizing structures measuring up to 6 x 2 x 0.50 m.

Zinc plating + Passivation

By applying passivation coating with chrome III, with a medium electro galvanizing 10-micron layer we achieve 172 hours of resistance to red corrosion.

For indoor applications, buildings without heating where condensation can occur, for example warehouses and sports centers. Outdoors, atmospheres with low levels of pollution. Countryside areas for the most part.
C1 and C2 corrosivity class

Zinc plating + Yellow passitivation

By applying a high resistance passivation layer with chrome III, with a medium electro galvanizing 10-micron layer we achieve 300 hours of resistance to red corrosion.

For indoor applications, manufacturing buildings with high humidity. Outdoors, urcountryside and industrial atmospheres with moderate pollution.
C1, C2 and C3 corrosivity class

Zinc plating + Bichromated passivation

By applying high resistance passivation, with a medium electro galvanizing 10-micron layer we achieve 400 hours of resistance to red corrosion.
For indoor applications, manufacturing buildings with high humidity. Outdoors, countryside and industrial atmospheres with moderate pollution.
