Hot-dip Galvanization Application

Hot-dip galvanization application



The corrosion resistance of galvanized sheet is a linear function of the thickness of the zinc coating. Thus, increasing the life of a product can be achieved by increasing the thickness of the zinc coating. There are some practical limits to the coating thickness that need to be considered. As the coating thickness is increased, there is a greater tendency to experience loss of coating adhesion during forming, the spot weld ability is decreased, and the surface finish is less smooth.


Galvanized Sheet is produced for applications where corrosion resistance is an important service requirement. These applications include air conditioning equipment; automotive parts including body panels and structural members; building panels; display cases; electrical boxes; electronic equipment; farm buildings; equipment and machinery; garbage cans; guide rails; heating equipment; furnace parts and ductwork; home laundry appliances; lighting fixtures; mailboxes; outdoor signs, playground equipment; prefabricated buildings; refrigerators and freezers; roofing; toolboxes; vending machines; and wall panels. In all of these applications, the galvanized coating is specified because it provides enhanced corrosion resistance, and thus, lengthens the useful life of the manufactured products.


For applications that involve high temperature exposure of the fabricated product such as fireplace parts, galvanized steel sheet should be applied with caution. The service temperature should not be over approximately 500 °F. At 500 °F and higher, the coating tends to deteriorate over a long period, and the zinc may alloy with the base metal causing embrittlement and mechanical failure of a structural part. Galvanized sheet is designed to provide long service at moderate temperatures.

Simply offers different rang of wire containers and metal racking in hot-dip galvanization. For more please visit our website at
