    Having worked with Firth Sheet Metal for some time on a variety of projects, I have been extremely pleased with both product quality and the standard of work. The initial site survey, detailed drawings, and project management, all lead to a first class installation.

    Firth Sheet Metal

    JD Industrial have been using Firth Sheet Metal for over 10 years and in that time we have built up a good and trusting working relationship with the team. They have supported us in our UK installations by responding quickly to quotations, and by answering technical queries – which has helped us no end – nothing is ever a problem or inconvenience! They have always been friendly and helpful and we thank them for their endless support over the years.

    Managing Director, JD Industrial

    We have been using the services of Firth Sheet Metal for over 20 years. Our experience and reason for the continued use of the services provided by Firth Sheet Metal is largely down to their professional approach to the manufacture and installation of their ductwork, along with a keen eye on health and safety.

    DW144 Ductwork

    All our products are manufactured to the highest standards, in-line with DW144 specification for sheet metal ductwork. All sections are produced with an integral continual girth flange from one complete section of steel sheet. This delivers strength and quality far beyond the requirements of DW/144.


    We are one of only a few UK companies licensed to manufacture Flameshield fire rated ductwork, compliant to BS 476 part 24. This is a non-coated, certified fire-rated ductwork system made from galvanised sheet metal on our dedicated machinery, which delivers performance and reliability expected of a leading brand.

    Duraduct Lt®

    We are one of only a few UK companies licensed to manufacture Promat DURADUCT LT,a Durasteel based fire rated product, compliant to BS 476 part 24 which provides up to 240 minutes fire resistance. This highly moisture resistant product retains integrity even when saturated, and does not absorb fluids such as cooking oil in kitchen extract systems.
