Constant pressure of the coal wil pull the screws out of PT lumber in a few days,, if you go the pipe route, use through bolts to a steel plate on the backof the wall.

Richard's idea is by far the easiest and most convenient.. use big eye-bolts through the side walls,, use a ratchet strap to winch the sides together,, once you have unloaded that part of the coal bin, and the strap is in the way,, remove it.. there is nothing for it to do if you have unloade the coal in that part of the bin.. Rachet straps are dirt cheap now, just a few bucks for the 1" ones and that is all that is needed.

Thanks everyone for the great advice. I think I'll go with the rachet straps and eye hooks. I figure this bin will cost around $400 for materials (pressure treated plywood is EXPENSIVE!) but hopefully, it'll last a while.

Thanks again.

Yep, I do lean to the overbuilt side at times but only because I have friends that are engineers and Mr. Murphy as my mentor!
Seriously, do protect the ratchet mechanisms from corrosion and keep an eye on the webbing.
Cables, a load binder and eye bolts with a large back plate might last longer if exposed to the elements.

Well Greg My bin is all screwed together since 1996 and I have Zero Pull outs The screws are drywall & deck 1"-2 1/2 " to 3"
and it is Much easier to had onto the bin to make it bigger down the road with screws in it then Nails And once again your
way Must be be the best way

JC, can you post a pic of your bin? Greg was talking about screws to hold a pipe flange that would have direct pull on the screws from the full weight of the load. Most fasteners have sideways pull only and are very strong in that direction. To pull directly out on any fastener is asking for a failure. I'm betting that none of your fasteners have direct out pull on them. It's rare that one would.
