Hi all, here goes another post and look forward to the replys I am after a steel gurder to go from gable to gable in my loft to support the roof purlin as i want to take the struts out to open the loft space up, I have had loads of advice on here and toying with a few things to support it, a stud wall to the new joists is the other option open to me but a bit hesitant on the weight of the roof on the joists and want to experiment with another method. The span of the gurder needs to be roughly 18-20 foot long what depth i am unsure of due to the lack of knowledge on these beams. I am looking for an H shape for the shere strength that it has. Firstly does anyone know what depth i need the gurder to be to support its own weight/length and at what price range am i roughly looking at? secondly as it would be a right faff on getting the straight length up to the loft without having to hire a crane could the length be divided into 2 and bolted together once up there, if this is visable would the strength be reduced due to the join. Thanks in advance Ian
