Additionally, it is also involved in trading of anti-wear powders and welding and cutting machinery. It provides super conditioning process at its manufacturing facilities, a surface treatment solution for machine components that enhances wear resistance, eliminates stress and improves their repairability ultimately extending their lifespan and reducing production costs. It has developed a synergistic system of forward integration whereby it manufactures special purpose electrodes and flux cored wires which are utilized for manufacturing wear resistance plates (commonly known as wear plates). These wear plates then become an integral part of majority of large industrial equipment which are made in its heavy engineering division and are significant contributor in manufacturing of industrial equipment used in core industries like cement, steel, power, mining, engineering, oil & gas, sugar, etc. This forward integration helps it in achieving efficiency in the production process and gaining competitive advantage, reducing product costs, enhancing supply chain control and reducing its dependency on third-party suppliers for its operations.
