building my own shed, about 4.8 x 2.8mtrs, the longest unsupported floor joist is about 2 meters and the floor itself is 22mm Caberfloor. Would 4x2 be sufficiently supportive?
shed floor question

nothing 'that' heavy
the floor would be three 4.8 lengths, with cross pieces at 400mm centres, with steel hangers to fix the cross joists to the long pieces. There will be a pad support in the middle of the long centre joist.
does this make sense?

there will be pad supports in all four corners and in the middle of each 4.8 mtr length.
the 4.8mtr lengths would be 4x2's, running the full length, shorter cross pieces at 400mm centres. All 4x2's.
cant be 4x2 if its supporting several bits off 4x2 it has to be around 6 times as strong maybe 9x3 you need to do the calculations
why not simplify a joist at 0/560/1120/1680/2240/2.8 ish
supported to the ground at 0/700/1400/2100/2800/3500

it will look something like this, but not so long or wide...
those timbers look around 8x2"
and the span is around 4m as thats the distance the the short mid timber is between the the blocks
as in start from the corner block to mid span transfer at 90% to the center timber then 90% to the center support
on top off that you are expecting a bit off 4x2 in the center off the shed to support 25% off the total floor load
lets see if you get a different answer in screwfix

got me in one! I did think those timbers were 6x2's but you could well be right! WTF do I know...not a lot it seems!
Think I'll be going with either 6x2 or 8x2 then....or a MUCH smaller shed

assuming you are having wooden framed walls and a minimum 12mm ply on the inside off the walls they will support the outer edge so if you go for say 6x2 all over and double up on the center timber or add another support at 25% and 75% i think you will be fine
but wait for other opinions as i tend to over engineer

If this is a shed floor what's stopping you supporting it at closer intervals than 2m?
