The introduction of Plastic Tank Radiators sees a period of continued growth for G&M

G&M developed an innovative method of allowing Plastic Tank Radiators to be refurbished. This was an instant success with their radiator repairer customers. With a huge demand for PTR cores, G&M continued to invest in equipment and machinery, additional employees, extra shifts and expansion of the premises. The end of the 90's also saw the retiral of Geoff Shrigley, the company`s founder, passing ownership over to his son Michael.
