1 2 the product shall be coated on one or both surfaces with equal or differential coating masses on the two surfaces. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness. Electrogalvanized sheet is manufactured by electroplating a pure zinc coating on one or two sides of carbon steel sheet. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness.

Electrolytic zinc coating weights are generally lower than those for hot dipped zinc coatings. Mild steel grades electrolytic zinc coated cold rolled steel products din en 10152 ze din en 10271 zn limitations parameters for testing and exceptional arrangements are to be taken from the pertinent standard. Coatings can be comprised of pure metals or metal alloys. Electrogalvanized sheet is manufactured by electroplating a pure zinc coating on one or two sides of carbon steel sheet.

From 1 4 pound to 1 pound tempers from soft deep draw to stiff temper t 5 ca. 1 1 this specification covers hot rolled and cold rolled steel sheet coated by the electrolytic process. Meets all aisi standards. Bright reflow 7c and or dull matte finish 5c coating weight.

Hot rolled sheet and strip 2. A continuous electrolytic process provides for a high grade surface finish of cold rolled sheet. Hot aluminised sheet delivery programme micro alloyed grades. In combination with standard surface treatments the coating acts as an efficient adhesive agent for a layer of paint or film.

The zinc is applied as an anti corrosion coating to either one or both surfaces of the steel.
