About Us

The Sterling Group of Companies is a conglomerate with a history dating back to the late 1950s.

The Group has interests in the industries of Fasteners and Fabricated Components, Finance and Real Estate with a primary interest in the manufacturing and trading of “Fasteners and Fabricated Components” for Transmission Towers and Microwave Antennas.

The Group started its journey 4 decades ago with Sterling Enterprises, as a trading outlet of the then mother-company, Ferreous Forging Company.

Our Founder & Managing Director “Mr. Uma Shankar Agarwal” started his journey from Ferreous Forging, his family business, in 1976. The company had built a reputation in quality Hot-Forged Bolts in the size-range upto M36 alongwith 25mm dia Fish-Bolts for the Indian and Iraqi Railways. The company was one of the first to manufacture Metric-Dimensional Bolts in the country.

He expanded the business in the year 1986 with a company named Bharat Industries (Galv.), a galvanizing unit with the then latest technology of Centrifugal Galvanizing for quality fasteners. In the year 1997 Bharat Galvanizing became a private limited company with the name Star Galvanizers Pvt. Ltd. In 1996 he founded Sterling Bolts Pvt. Ltd. a forging unit of Bolts, Nuts and Fabricated items.

In the year 2008 he has stepped into financial business by opening Sterling Finvest Pvt. Ltd., an NBFC. In 2010 he has started Sterling Nirman Pvt. Ltd. as he has a vision of stepping into the Real Estate business.

In 2013, Star Galvanizers Pvt. Ltd. was merged with Sterling Bolts Pvt. Ltd. bringing all operations under one roof.
