Electro Galvanized Steel Sheet Astm

Electro galvanized steel this is a standard commercial quality electro galvanized steel sheet which has been electrolytically zinc coated in coils by modern methods.

Electro galvanized steel sheet astm. The process consists of immersing the steel in a cold zinc bath that has an electrical current running through it. 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. The electrogalvanizing process is often referred to as zinc electroplated or zinc coated. Ss grades 25 70.

The process involves steel being immersed in a cold zinc bath. Cs ds dds edds types a b. 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. A zinc coated carbon steel similar to galvanized and galvannealed.

Electro galvanized steel is a zinc coated metal that is produced through an electrochemical process. This continuous electrolytic coating process can be used to apply the coating onto the surface of the steel sheet with an exceptionally uniform thickness. An electrical current is run through the bath. Ultimate service life depends on coating thickness and the severity of the environment.

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. Electro galvanized steel is. The result is a uniform layer of zinc bonded to the steel electrolytically to prevent corrosion. Electrogalvanized sheet is manufactured by electroplating a pure zinc coating on one or two sides of carbon steel sheet.
