Rajnandini Metal Limited is primarily involved in trading ferrous and non-ferrous metal scraps such as copper wires and ingot scrap. It operates as an intermediary in the metals supply chain, linking suppliers and consumers through a business-to-business model.

Originally focused solely on trading, Rajnandini Metal Limited expanded into manufacturing copper products in 2019, establishing a dedicated production unit in Bawal. This strategic shift marked rapid growth in copper manufacturing.

Since its IPO in 2018, Rajnandini Metal Limited has continually expanded its production capacity, installing advanced machinery like rod breakdown and bunching machines to enhance output and profitability.

In 2021, Rajnandini Metal Limited ventured into the agriculture sector by launching a new product, the Submersible Winding Wire, showcasing diversification in its product offerings.
