Our clients Heasman and Sadler have just had a new piece of plant installed in their Oxfordshire factory, the I-FOLD automated ducting machine streamlines the production of square ductwork to maximise efficiency. The machine can fold sheet metal up to 1.6mm thick. Heasmans are ductwork contractors based in Oxfordshire, covering Wiltshire, Berkshire, Gloucestershire and further afield across London and the home counties.
