Galvanized plating is used in a multitude of materials in the construction industry including large structural shapes. But don t be a magpie and just pick up the shiny object think about the use. When comparing stainless steel vs. When should you use galvanized steel or zinc plated steel.

Both methods add a protective layer of zinc to the steel. Zinc plating is a popular choice for coating nuts bolts washers metal stampings automotive parts fabricated parts for industrial applications as well as sheet metals. Zinc plating on the other hand is immersed in a cold chemical solution of zinc and uses an electrical current to apply a layer of zinc. The steel and the zinc become one.

Steel when being hot dip galvanised is dipped into a 450 c bath of molten liquid zinc. Galvanized coatings are almost always several times thicker than electroplated coatings so galvanized fasteners greatly outlast zinc plated fasteners. Zinc plating looks shiny and pretty galvanized looks dull. The galvanized coating is applied over steel to protect that steel not the other non coated steel that the galvanized steel happens to be in contact with.

The steel and the liquid zinc bond together because of the high temperature. Stainless steel is the most durable option when it comes to different types of nuts. Zinc plated and galvanized fasteners are made of steel with a sacrificial zinc coating.
