When I looked at travis Perkins webpage I looked at the same catnic and for the 4.5 m span it was around £900 now I would of got discount but even at 50%(which I don't think I would of got ) that still works out £450 and my steel was £300 and to be fair its well over engineered.
Your opening and steel hasn't got the gable ends on , I've got another 2 metres to go above the door plus it's got x3 steels loading on the walls holding up the roof.
