Now, since I only want a dozen panels for my own DIY then roll forming may be out.
There may be no roll forming line which produces the profile I want or there may be only one suitable roll forming line in the world but no competitive pressure on the company to charge reasonable prices for small orders and so they can charge what they like, (MN - Germany, £600 per sheet) more than I can afford.
