Who We Are?

Bangor Steel Fabrications Ltd – a family run business based in County Down, Northern Ireland, is a supply manufacturer of both rectangular duct work with bespoke fittings & spiral duct work with associated fittings including bends, attenuators, flexible duct work and grilles. Every building requires good ventilation. And that means great quality ventilation equipment, supplied by experts


Our modern production facilities consist of two factories.  One for the manufacture of spiral ductwork ranging from 100mm right through to 2000mm spiral ductwork and related items and the main factory for all other services provided; giving a combined capacity of approximately 2500 sq. Meters.  Unlike any of our competitors, we make our own spiral ductwork and fittings, and currently, are the only manufacturer of 2000mm diameter ductwork in accordance to HVCA requirements.


With over 25 combined years experience and our fully digital workflow from estimating through to manufacture, our highly experienced workforce, knowledgeable in all areas of the industry offer a simple and accessible way of purchasing ventilation and ducting supplies from order right through to delivery.




Our 2500 sq. Meter production facility can manufacture and supply galvanized and stainless steel circular ductwork and fittings of any type up to 2000mm diameter and if requested, outlets and pre-installed flanges at short notice.  Unlike most ventilation businesses, our circular fittings can be made to the clients specification.  Currently, we are the only business in Ireland that can manufacture 2000mm diameter spiral ductwork to HVCA specifications.

Supplying quality ductwork can only be achieved with ongoing investment in the best equipment and new technologies, paired with a fully qualified and experienced team.

Taking satisfaction in delivering our superior service with excellent amenities capable of carrying out all types of sheet metal work.
