Using fence posts for construction?

[mls]

Hi,

I'm building a log store / garden store to match an existing slate tiled timber construction garage.

I'm not sure where to source the timber upright posts. Lots of places have 5 or 6 inch fence posts, as long as 2.4m, but I'm not sure if they are advisable for construction? They are usually treated sawn timber.

I'm thinking of 6 posts say 2m tall in each corner and 2.4m pair in the middle to support the ridge of a pitched slate roof.

I don't want to go to an oak frame but is there something in between oak framing at one end and fence posts at the other end? If so, anyone know where to source something like that?

Thanks in advance Martin

A good timber yard or sawmill will do square sawn timber in common sizes like 2x2 3x3 4x4 5x5 6x6 8x8... etc in lengths up to 4.8m.
Some places also do round, machined or peeled, but they're not so easy for building with as you don't have a flat face to fix to
