Hi people I am planning on rebuilding the flat roof of my garage as the current roof is rotten.
The size is 7.2m x 5.2m, and the steel beam will go across the middle giving a span of 3.6m from beam to wall. using an online span table i found I believe I require 8x2 c24 timber joists at 400mm centres.
My question is what size beam will I need to hold these joist?
I spoke to a local steel yard without going into much detail, who said 200mm high by 135mm wide light weight 25kg per meter. Would something like that do the job?
Many Thanks
