Hi Guys.
I'm planning on building a per pergola type structure with a glass roof. I'll have six rolled Steel Joists 100mm x 45mm each doing a 5m span. They will be supporting six sheets of glass weighing about 50kg each. So each RSJ (I-Beam) will be supporting about 125kg.
The question... Is a five meter span OK for this amount of weight?
It will look something like the below pic' but bigger and different. I just googled for the pic to help explain the structure.
LOL sorry, here is the pic'.
