This is achieved through a multi-step process where a steel sheet is immersed in pure molten zinc at a very high temperature, bonding the zinc to the steel. It is used in the agricultural and construction industry, as a component in different pieces of heavy machinery. Hot Dipped Galvanized vs Galvanized Steel Galvanized aluminum coated with zinc is used most commonly perhaps in aluminum roofing, water pipes, and similar constructions. The carbon steel sheet are galvanized before producing the cable ladders. Galvanization is a process that coats iron or steel with a zinc layer that protects it from corrosion while the zinc lasts. mild steel has a certain small range of carbon to provide greater hardness than if there is too little or too much carbon. Galvanize definition, to stimulate by or as if by a galvanic current. In general, iron contains a certain amount of carbon because of the process. The most common products covered by this tracker include hot-dipped galvanized steel (HDG), electro-galvanized steel (ELG), pre-painted steel (PPGI) and tinplate. The aluminum is added to improve the adhesion between the coating and the steel substrate during formation. At the time, North American made vehicles were experiencing severe durability issues due to rust – a serious issue that (quite literally) couldn’t be solved by just throwing on another coat of paint.
