FREMONT, CA: Protective metallic coatings are the coatings comprising metal alloy or metallic element and can be applied to the surface using a sprayer in a chemical, mechanical, or electrochemical manner. These coatings are mostly applied to equipment to give it a glossy or shiny appearance while protecting it from corrosion, oxidation, and sunlight.
Let us look at the types and benefits of protective metallic coatings:

This galvanizing process involves iron, coating steel, or ferrous materials with a zinc layer. The process is performed by moving the metal through molten zinc at a very high temperature of 860°F (460°C), which forms zinc carbonate (ZnCO3). This material has considerable strength to protect steel surfaces and fend off corrosion.
Thermal Spraying
This process required metallic coating materials that are finely divided and placed in a molten condition to develop a coating. The coating material itself can be in the form of powder, molten, wire, or ceramic rod materials.
Electroplating
The process of electroplating consists of coating a metal surface with a thin layer of metal through electrolysis, which, in turn, enhances the corrosion resistance of the metal.
There are a variety of coatings that can be applied to a metal surface. However, the type of coating selected must be determined on the basis of the characteristics and use of the metal product. Some metal coatings are formulated with the sole purpose of protecting metal against debris, corrosion, rust, and dirt. These applications can include airplanes, automobiles, boats, trains, and other heavy outdoor equipment.
