Electro Galvanized Steel Sheet Astm

Hsla grades 50 70.

Electro galvanized steel sheet astm.

The process involves steel being immersed in a cold zinc bath. Electrogalvanized sheet is manufactured by electroplating a pure zinc coating on one or two sides of carbon steel sheet. Electro galvanized astm a 879 this specification covers the requirements for zinc coatings applied by the electrolytic process to any grade of hot rolled or cold rolled steel sheets for applications requiring designation of the coating mass on each surface. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness.

The process consists of immersing the steel in a cold zinc bath that has an electrical current running through it. Product features corrosion resistance the zinc coating protects the base metal by providing a barrier to corrosive elements and also by the sacrificial nature of the coating.

Electrogalvanized steel product description. Electro galvanized steel is. The electro galvanized sheet is produced as commercial quality drawing quality drawing quality special killed and structural or physical quality and is readily available in three zinc coating class weights of a b or c. Ultimate service life depends on coating thickness and the severity of the environment.

The electrogalvanizing process is often referred to as zinc electroplated or zinc coated. Coating weights 03g through 24g. A zinc coated carbon steel similar to galvanized and galvannealed. Electro galvanized steel this is a standard commercial quality electro galvanized steel sheet which has been electrolytically zinc coated in coils by modern methods.
