At Unispares India, we are a leading manufacturer of Construction, Agricultural, and Automotive parts and spare parts. We specialize in supplying industrial machine parts and components throughout India, as well as the global market. Additionally, we export quality custom and OEM parts to various locations. We are proud to offer exceptional service for surface coating facilities, ensuring the production of top-quality rust-free parts and components. Furthermore, all surface coating and processes are carried out in accordance with ISO DIN or any other desired standards.

Mostly it is seen that special surface treatment is required for metal surfaces, in order to have the desired optimum properties. The coating method differs for different applications. We at Unispares India have the following surface coating techniques:


When it comes to metal surfaces, special surface treatment is often necessary to achieve the desired optimum properties. The coating method utilized can vary depending on the specific application. Here at Unispares India, we employ a variety of surface coating techniques. For instance, Electroplating/Galvanizing is the most commonly used method for surface coating, suitable for various applications. During this process, a coating is created by electro-deposition of zinc onto steel sheets and strips. The operation is continuous, and the coating thickness is minimal.

  1. Blue – Blue Zinc is also called clear passivate or silver zinc. Blue chromates provide 48 hours of protection against white corrosion.
  2. Yellow – Yellow Zinc Plating refers to the color of the chromate that is applied after zinc gets deposited on the surface. Yellow Chromate actually protects from corroding.
  3. Black – Black zinc plating is the color chromate that is applied after the plating process. It includes a layer of zinc on the surface by black chromate.

Chrome VI free
It’s essential to note that the thickness of the passivating layer greatly affects the ability of the chromate layer to protect zinc from corrosion. For zinc iron, we use Chrome VI free, which helps to increase surface strength and meets the higher corrosion standards required by the automotive industry. At Unispares India, we take pride in utilizing these techniques to produce high-quality spare parts and components for the automotive industry.

Powder Coating

Powder coating is a dry finishing process. The coating material is mainly made up of finely grounded particles of resin and pigment for color, along with additives for a specific function like providing gloss finishing or hardness. At Unispares India we use it to produce workpiece which are scratch resistance, corrosion resistance, and abrasion-proof. The process helps us cut costs, improved efficiency, and facilitates compliance with the environment.

Hot Dip Galvanization

The hot-dip galvanization process is very versatile and the component ranging from small nuts and bolts to long structural sections can be treated, hence is extensively used by us. The unique process is to immerse clean steel into molten zinc, a series of zinc-iron alloys formed. This results in providing, a robust coating which is an integral part of the steel.


Before painting, the surface is usually machined to a bright finish, and further mechanically polished, and then subjected to cleaning solvent. The paint powder is applied electrostatically to achieve a uniform deposit on any intricate workpiece.

Chrome, Nickel Coating

Nickel chrome plating is the most common technique wherein nickel and chromium electrodeposits form multiple layered finishes on any component. We at Unispares India use it for various components and spare parts for the construction, agricultural, and automotive industry. We can achieve a shiny and glossy appearance on parts or spare parts.

Dacromet and Geomat

We do Geomet and Dacromet zinc flake coating using the dip-spin/spray process. It is one of the most advanced and environmentally friendly ways of surface coating. Unispares India uses it for corrosion-resistant, better adhesion, heat resistant property to the workpiece. It is used for machine parts and spare parts of automotives, agricultural, and construction equipment.
