About Constant Group

About Constant Group

In 1969, Harry Garlick was told he ‘didn’t have enough money to buy a fish and chip shop’, let alone an aluminium trading company. Harry proved them wrong and Constant Aluminium Supplies Ltd was formed on Greenhalgh Street off Oldham Road in 1970. Delighted that over 45 years later, lead by two further generations of Garlicks, his company still flourishes today.
