trogers Posted July 13, 2010 Share Posted July 13, 2010 (edited) Plan to walk on it in the future? Purlins span rafters. How far apart are the rafters? Edited July 13, 2010 by trogers Link to comment Share on other sites More sharing options...
TPI Posted July 13, 2010 Share Posted July 13, 2010 Can anyone advice on what size purlins for 120*50 Trilon lightweight roof tiles. I think you need to talk to the supplier, most are pretty good. Link to comment Share on other sites More sharing options...
petertucker48 Posted July 14, 2010 Author Share Posted July 14, 2010 Plan to walk on it in the future? Purlins span rafters. How far apart are the rafters? The rafters (3" C section laid on edge length 6.5 metres) are spaced at 110CM. Not to be walked on. Link to comment Share on other sites More sharing options...
