Established 1970

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.

Our team

Family founded, and operated

3rd generation family operated, employing 80 plus members of staff in our Oldham factory from time served design engineers to fully skilled sheet metal workers and welders, whilst developing the next wave of talent through our apprenticeship scheme.
