DDL are specialist rectangular ductwork manufacturers.


We regularly produce and supply items from the typical ventilation system: PIPE, BENDS, TAPERS, SETS, SQUARE TO ROUNDS.

Our full-time welders can manufacture stainless steel canopies made to order and fully welded drip trays.Better still these can all be made from 16-24 gauge thickness galvanised sheet (ALL of which is STOCKED), depending on your requirements.

If it is simply a work surface or a unit you need cladded we can also do this, and with fire retardant acoustic foam.
