Could someone please advise.
Im about to put the loft floor joists into the steel beams.
The joists are c24, 75mm x 200mm. Length is 4.7 meters.
The steel beam is 200 x 200mm x 46kg
My question is, how much of the wooden joist needs to be sitting on the bottom flange of the steel beam?
Ive read previously that you need 40mm minimum? Is this correct? I was thinking of having mine about 70mm sitting on the steel?
Any advice is much appreciated
