I have some 2.4mt 150mm X 100mm treated pine sleeper left over from previous project.

Can I use these treated pine sleeper as pergola posts? are these sleeper strong enough?

Or can I screw two sleepers together as one post?

Thanks!!!

G'day Andrew and welcome aboard':2tsup::2tsup::2tsup:

Treated pine that size is plenty strong enough for posts. Most posts for your purpose are 100mm square.

I takeit you are mounting the posts in stirrups.

They'd be strong enough, but I'd be worried about how much they move over time. the last lot of sleepers I bought had some *very* wet ones in there, and they warped a fair bit on drying. The ones that were bolted together (I made a flight of stairs out of them) didn't move too much.

Cheers,
Dave

Just beware that trated pine sleepers are not a stress graded structural timber. They are likely to have defects such as large knots, sloping grain and other defects that create weaknesses.
