Firmac UK Ltd

World leading manufacturer of sheet metal duct forming technology

For over 30 years, Firmac Ltd. has led the way in the design and manufacture of high quality metal duct forming equipment and HVAC machinery manufactured and built entirely in the UK. We have customers in more than 50 countries throughout the world who rely on our machinery to produce sheet metal ductwork, which is then most commonly used in buildings to supply heating, ventilation and air conditioning (HVAC).

Leading the way

The Firmac brand is synonymous with innovation, quality and reliability and is recognised across the globe. Our desire to improve and innovate is ingrained within the company and our reputation for developing leading edge technology is respected throughout the industry.

The Firth/Firmac Group has been manufacturing ductwork for over 50 years and still has an active duct working business running alongside Firmac. This gives us a unique position in our marketplace, allowing us to provide a greater insight and understanding of our customers’ challenges and aspirations.

We are proud to remain a family owned business in this corporate world of mergers and acquisitions, allowing us absolute autonomy in continuing to provide the best machinery available in the market, supported by our team of experienced and committed engineers.
