HOT DIP GALVANIZED - AK Steel

HOT DIP GALVANIZED STEEL, known as ZINCGRIP&Steel, is continuously coated on both sides with a zinc coating. The hot dip process, pioneered by AK Steel, provides a tight metallurgical bond between the steel and the coating. This process results in a material with the strength and formability of steel plus the corrosion protection of zinc.Hot Dip Galv versus Cold Rolled Steel - Metal and The Study of Aging Cold Rolled and Hot Dip GalvanizedJul 16, 2008If you need the galvanizing for corrosion protection, then you have to figure in the cost of replacement of the cold rolled (non-galvanized) steel when it corrodes faster than the galvanized steel. For example, if the CRS is half the price of HDG, but lasts a quarter of the life, you're not saving money by using cold rolled steel in the long run.Hot-Dip Galvanized Strip Wuppermann AGHot dip galvanizing" describes the process of metallic surface coating of steel with a thin layer of hot zinc (450°C). Hot dip galvanizing of steel is one of several galvanizing methods. A distinction is made between discontinuous batch galvanizing and continuous strip galvanizing.
