What are the different types of metal finishes?

Metal finishing in the common terms is mostly thought of for interior decor where the metal items are coated with a powder of a glossy finish to give an aesthetic appeal. During the process a thin layer of coating is applied on the surface and now the metal finishing company uses different methods for coating the Meta and giving it a flawless finish.

Here are some of the metal finishes that you should know about.


In this process, professionals do the plating of a thin layer of metal including zinc, cadmium, chromium, or nickel to change the condition of the surface of the substrates. The electroplating method produces an electric current for coating the substrate, and electroless plating employs an autocatalytic process where substrate is just like a catalyst in the reaction. It gives many benefits like improves durability, exterior appearance, corrosion resistance, and surface friction.

Electroless plating

In this process a layer of metal is uniformly coated on the substrate without using an electrical charge. In this process, nickel is mostly used because it helps to give a uniform thickness to the substrate with shaped objects. This process helps to improve the resistance in oxidation, corrosion, and wear resistance.

Powder coat

In this process, dry plastic powder is melted on the metal to generate matte, glossy, and texturedcoating. The powder is applied on the metal electrostatically and then it is put under heat which makes it to flow and get hard.

Hot blackening

In this process, machines are used to coat the surface of the product with a thin layer of black oxide. It helps to give a matte black finish and also high abrasion resistance. This process uses high temperature in which professionals insert the product into a series of tanks including cleaners, coolants, and caustics.
