well i've got a friend on the case he has a contact through work who he thinks can get me what i need. however i found a place today on the net that will supply full 7.6mtr lengths of both types of box section i need.. and the 50 x 25 x 3 is a good price 2 lengths delivered for £72 but the 60 x 40 is a big jump and i honestly only need around 2.5mtrs so i'm getting some quotes from ebay guys as we speak
