G.S. Business Group, founded by the visionary Baba Gurmukh Singh in 1938, traces its roots to GS Auto, a pioneering company manufacturing chassis-suspension components. Despite India’s pre-independence era, GS Auto flourished, earning a stellar reputation for quality. In 1992, the group diversified into the heat exchanger domain, establishing GS Radiators Ltd. with technical collaboration from the United Kingdom’s Llanelli Radiators Ltd., later a part of Japan’s Calsonic Kansei Corporation.

Ranjodh, a mechanical engineering graduate from Guru Nanak Dev Engineering College, joined the company in 1988. His strategic leadership propelled GS Radiators Ltd. to new heights, earning him the directorship. In 2008, GS Engitech Private Ltd. emerged, diversifying into sheet metal, combine harvester parts, and CNC-milled components. Ranjodh, now the managing director, expanded the family’s legacy. Jaskaran, a 2018 engineering graduate, joined the fold, leading to the establishment of MacTech International Pvt. Ltd. in 2018. The group continues its commitment to excellence, innovation, and quality in the ever-evolving automotive and manufacturing landscape.
