most only want to sell you sheets , what you do with them after that is up to you . even then its hard to find a good price on alloy here , I use a company in glen grimley , but usually profiles , they do sheet though. Aalco , but nice enough to deal with . I used to get stuff cut from John Spratt but hes closed new . Theres a coach builders outside of Lisburn whos name I forget , but hard hard hard to pay.
