Logan Posted May 6 Share Posted May 6 I’m looking to build a 3mx5.7m deck and wondering what is the minimum height of C16 joists I can get away with that will safely support the structure? The reason being, I’d like to keep it as low as possible due to it being the highest point of the garden already. Thanks in advance! Link to comment Share on other sites More sharing options...
ProDave Posted May 6 Share Posted May 6 Unless it's high off the ground, which you don't want, you can give the joists as many intermediate supports as you like, and 4*2 would do nicely. Link to comment Share on other sites More sharing options...
Conor Posted May 6 Share Posted May 6 As Dave says, 4x2s, supported every 1.2m or so with bits of block /pavers. Link to comment Share on other sites More sharing options...
JohnMo Posted May 6 Share Posted May 6 Really depends on how solid you want it to feel and how they are supported and the span they have stretch across. Outs is off the ground so attached to ground in a limited way via pillars. Most of ours are in in either 47x225 or 47x175 on 400mm centres. The 175mm can span about 3m or so and the 225mm 4m+. If on the ground mounted as other responders have noted. Link to comment Share on other sites More sharing options...
