Coatings are defined as a thin outer layer… A simple definition for a very complicated and wide ranging subject. Metal coating in caparison to other material coatings is a vast industry comprised of many different methods and innumerable applications.

The earliest metal coatings to deter corrosion were more than likely some form of animal fat frequently applied by hand rubbing . An iron axe or sword was a very precious and useful piece of equipment to early societies. Their survival probably hinged on the useable condition of these tools.

The first industrial metal coatings unlike ceramic coating were likely some form of paint and applied with a bristle type applicator, more commonly known as a paint brush. Many metal coatings are still applied with a brush, but industry required more sophisticated methods of application and methods have evolved to meet the needs of manufacturing.

Metallic coating methods:

- electroplating

- hot-dip galvanizing

- anodizing

- thermal spraying

- cladding

- diffusion coating

- porcelain coating

- glass lining

However complicated it seems to be, a metal coating system has two functions:

- A physical barrier separating the metal from contact with a corrosive element

- a chemical barrier to control the environment at the metal and coating contact area.

The effectiveness of a metal coating method often derives its longevity from several factors.

- coating selection to meet the conditions

- surface preparation

- application conditions

- routine inspection and maintenance

The choices of metal coating methods are many and a science unto itself. Natural conditions are a dynamic and ever changing environment and rarely duplicated in a laboratory. It is best to use a known application for the best result.These benefits are also the same significant reasons that you must keep in mind. There are numerous manufacturers of this PV panels that offers you design variant to choose from and make the PV panel units easier to install in your homes.
