![]() If I use 450mm spacing, how do I work out what joists are okay? Originally I found 70x45mm timber which I thought should okay for the joists given it's hardwood F27 but I can't find a span table to work it out. But I would prefer 3 bearers with smaller wood but the span tables don't have, say, 1600mm span loads.īut the Joists needing to be 170x45 (1200mm span width) means I am beyond my 300mm limit for my deck. I can accept 2/170x45 bearers as these will run the lenght of the deck (2 bearers spaning 2400mm each, deck is 3800mm wide). The second attachment is the bearer F27 hardwood with the same span/floor load widths. I was going to have joists at about 450mm spacings. My issue is that spanning tables for hardwood seem to limit floor load width (which I assume is span load width) to 1200mm. I want to have the joists above the bearers as this will improve airflow. The deck will be 3800mm wide, 3000mm long. As such I will probably use hardwood as I can get F17-F27, H4 equivalent timber, so I don't have to worry about water and can try to get smaller bearers and joists. My issue is that I am building a deck with little clearance. * Lengths made to order, lead times apply.I know this is an old thread but it's been the most helpful in learning how to read span tables.
