Galvanized Steel Zinc Plated Steel

When comparing stainless steel vs.

Galvanized steel zinc plated steel.

The steel and the zinc become one. There are some instances when zinc is electrically connected to dissimilar metals on purpose such as on boats or on pipelines. Zinc plated and galvanized fasteners are made of steel with a sacrificial zinc coating. 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. 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. Zinc plating looks shiny and pretty galvanized looks dull.

Both add a layer of zinc to the outside of the product.

Galvanized nuts it s important to realize that stainless steel itself is a material and galvanizing and zinc plating are forms of coating. When should you use galvanized steel or zinc plated steel.
