UK makers of metal ductwork say they are being forced into producing unnecessarily costly products because of outmoded galvanising standards.
Paul Adlam of the Association of Ductwork Contractors and Allied Services (Adcas) said that the galvanising requirements in current ductwork specifications were ‘madness’.
He said: “The current standard is 275 g a square metre, which would last up to 300 years. If you brought it down to 150 g, it would still last 200 years, but that is not allowed. What does that extra zinc mean to the cost of production and the environment?”
Mr Adlam called for a change in the spec, since not only was it costing Adcas members around £4 million a year in additional material costs, but it was also penalising UK producers. “There is already a European threat. We are already seeing Irish product, for instance, which is allowed to be 150 g – they will obviously be cheaper, and who is going to police the thickness when it is onsite? We just want a level playing field and a product that is right for the environment. It could go down to 100 g and still be fit for purpose.”
