METAL COATING

Metal Coating :

Coatings that are applied to metal in order to protect the metal and reduce wear and tear. An unprotected metal will rust and corrode due to environmental exposure. By coating the metal, an extra layer of protection is provided. A variety of coatings can be applied to metal, and the choice of which type of coating to apply is determined by the end use of the metal product. Some types of metal coatings are designed to protect the metal from rust, corrosion, dirt and debris.In other cases, metal coatings are used to act as lubricants or torque agents. For example, screws, bolts, and fasteners are metal objects that are often treated with a metal coating in order to make them easier to unscrew or tighten.
