The Aerospace and Defence industries are quality focused. Here, the quality of manufacturing and finishing has the utmost importance as the failure of any component could have devastating consequences. Moreover, these components must be extremely durable throughout their service life.

Growel has supplied Anodizing, Phosphating, Hard Chrome and Zinc plating plants to the Defense and Aerospace Industries.


Aluminium is used in abundance in the Aerospace sector. Anodizing treatment is usually applied to Aluminium to make it suitable for Aerospace application. Anodizing increases corrosion resistance, improves resistance to wear, improves surface hardness and provides an aesthetic finish. Growel has supplied a range of surface treatment plants for specialized Aerospace components.

Hard Chrome:

Chrome plating of gun barrel is an essential feature in the manufacturing of conventional arms and ammunitions. It enhances the life of the barrel multi-fold. The process is used to deposit a suitable hard chrome layer on the inner wall of the barrel cylinder. The geometry of the object, and the stringent control on thickness of plating, calls for a very specialized system approach. The diameter and the length of the barrel, play a very critical role in determining the design of the plating system. The knowledge and the experience are proprietary, scarce, and difficult to find. Grauer and Weil has been manufacturing such systems for nearly two decades.

Surface Finishing provides several benefits for Aerospace and Defence components:

  • Corrosion Resistance
  • Wear Resistance
  • Aesthetic Appearance
  • Increases Surface Hardness
  • Heat Resistance

To achieve the above-mentioned benefits various proceses are employed on the components:
