This product was developed from a need to improve on the Hot-Dipped Galvanised grades for use within the autobody industry and other applications where good corrosion resistance was enhanced with an excellent surface for painting.

In this process the surface of the strip is meticulously cleaned by electrochemical and electrolytic means, then activated chemically to allow a good `take` on the surface during the Zinc coating process. Actual coating is achieved when the strip passes between zinc plates (or anodes) suspended in vertical plating cells through which the plating solution of Zinc Sulphate - known as the "electrolyte" - is pumped.

The thickness of the Zinc coating is controlled by the strength of the current and the speed at which the coil passes through the cell assembly, and on exiting, it is thoroughly rinsed and a protective treatment is applied before the strip is rewound into coil form, now ready for packing and despatch.

Electro-Zinc coated material is available in a number of grades and coating thicknesses.
...........................................................................................................................
Our standard stock grades are:
DC01+ZE / DC04+ZE / DC06+ZE

with Zinc coating thicknesses of:
2.5 microns / 5.0 microns / 7.5 microns

The general stock is coated with equal weights on both sides, but single-sided material can be obtained if required, subject to order quantity.
