Hot Dip Zinc Coated Steel Sheet

Density g cc typical of astm steel.

Hot dip zinc coated steel sheet.

Zincgrip steel is continuously coated on both sides with a zinc coating using a hot dip process that we originally pioneered. 1 1 this specification covers steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process in coils and cut lengths. Zinc protects the base metal by providing a barrier to corrosive elements and preferentially corroding in place of the base steel. It is the process of coating iron and steel with zinc which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 c 840 f.

Wheeling nippon steel is the first company in the americas to produce such a product. Coating weight g m alloyed coating a 25. Find the most up to date version of astm a at engineering. Hot dip galvanization is a form of galvanization.

When exposed to the atmosphere the pure zinc zn reacts with oxygen o 2 to form zinc oxide zno which further reacts with carbon dioxide co 2 to form zinc carbonate znco 3 a usually dull grey fairly strong material that protects. With its tight metallurgical bond between the steel and the coating zincgrip steel provides the strength and formability of steel plus the corrosion protection of zinc. 1 2 the product is produced in various zinc or zinc iron alloy coating weights masses or coating designations as shown in table 1 and in table s2 1. Protection against rust with zinc coating zinc coating z produced on both sides by hot dip galvanizing extends the service life of the end product by protecting the steel from corrosion.
