The sheet galvanizing method is typically employed with steel sheets and other kinds of steel materials such as wires in order to increase their resistance to oxidation. The resulting layer of coating is thicker compared to materials which undergo electroplating, but thinner compared to the thermal spray method.
Also known as continuous sheet galvanizing, this method is a coil-to-coil process wherein a steel sheet, wire, or strip undergoes a constant pressure through a continually-moving ribbon which applies a layer of zinc that bonds with the material. The resulting thickness can range from around 1.70 inches to as much as 72 inches, depending on the desired figure.
After surface preparation of the steel, the material undergoes a method of annealing in order to increase its strength, and formable properties. This is also a way to remove other unwanted substances from the material before it undergoes galvanization.
Steel sheets that have undergone this galvanizing method have a wide variety of applications, including in-car bodies, corrugated roofing materials, piping, and the like.
