Galvanized Steel Zinc Plated Steel

Zinc plating looks shiny and pretty galvanized looks dull.

Galvanized steel zinc plated steel.

Zinc plated and galvanized fasteners are made of steel with a sacrificial zinc coating. 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.

Galvanized nuts it s important to realize that stainless steel itself is a material and galvanizing and zinc plating are forms of coating. Galvanized plating is used in a multitude of materials in the construction industry including large structural shapes. Both methods add a protective layer of zinc to the steel. That coating is eventually consumed.

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. But don t be a magpie and just pick up the shiny object think about the use. There are some instances when zinc is electrically connected to dissimilar metals on purpose such as on boats or on pipelines. Stainless steel is the most durable option when it comes to different types of nuts.

When comparing stainless steel vs. 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. 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.
