Hot Dip Zinc Coated Steel Sheet

Hot dip galvanization is a form of galvanization.

Hot dip zinc coated steel sheet.

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. Coating weight g m alloyed coating a 25. 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. 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.

Physical properties original value comments. 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. Wheeling nippon steel is the first company in the americas to produce such a product. Density g cc typical of astm steel.

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.
