Do they make solid steel seat posts?

Thompsons are great posts, I love'd the one on my last bike before it was stolen, and I was well over 300lbs then.
From a mechanical perspective, a hollow post (with heavy enough walls) will actually resist bending much better than a solid one. In theory, a fairly thick walled hollow post filled with a highly rigid foam would be even stronger (that's how the long bones in your body are as strong but light as they are) but I don't know how you would make one.

I've never heard of a solid seatpost. If the seatpost is breaking the best solution really would be a frame with a longer seat tube so there's less seatpost sticking out and less bending.

Had to make my own
I had to make my own out of a solid chunk of 440 stainless steel the seat post is about 19 inches long I had to Mill down the top so I can fit a seat bracket on it.
Being 6'9" and over 350 I needed something a little bit stronger

I've always found that the saddle rails are the weak point, not the seatpost. What kind of saddle are you using?

Except for very large people like Bigjoe, a solid steel seat post is too heavy. Get a longer, stronger, hollow one.
It needs to be long enough to go into the frame far enough.
I have bent seat posts. It happens when you put extra stress on them. For example, going over a small jump.

The 13/16 seatposts for my Schwinn DX klunker were very bad about bending on easy trail rides until I hammered a 3/4" solid rod into one of them. It has been in there for 15 years now, and no more bent seatposts.

Is there no way for the software these forums run on to insert a notification that the thread is 14 (or whatever) freaking years old?! Seriously, I was catching up from the o.p. onward and didn't twig until I saw a post from the site founder! That's just a bit ridiculous. There isn't any product in a 14 y.o. post that will still be on the market today. Any links will deliver a 404 not found error. All that is done by continuing to ignore the idjits that get a kick out of this is encourage them to go ever further backwards and defend it as nothing to get excited over.

Bent seatposts never seem to go out of style.
