Electrolytic zinc coated sheet 5. Coatings can be comprised of pure metals or metal alloys. For specific coatings refer to specifications a879 a879m and a918.

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. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness. 1 1 this specification covers hot rolled and cold rolled steel sheet coated by the electrolytic process.

1 2 the product shall be coated on one or both surfaces with equal or differential coating masses on the two surfaces. Electrolytic zinc coated steel electrogalvanized is a cold reduced steel product which has been given a thin coating of zinc by electrolytic deposition. A continuous electrolytic process provides for a high grade surface finish of cold rolled sheet. Electrolytic zinc coating weights are generally lower than those for hot dipped zinc coatings.

1 5 the product is available in three zinc coating classes as listed in table 1.
