I'm going to be putting up two louvered panels that will hold plastic hanging bins (think akro-bin type). I won't be able to mount the panels on studs, so I'm trying to decide if I should mount regular boards or OSB behind the panels. The panels weigh 11lbs each, and I'll probably have no more than a 100-150lbs of stuff in all the bins.
If I go with OSB, I would put up something larger than the panels do it would easy to mount other things from this area later. But, I'm concerned OSB isn't strong enough to support the weight. Is it?
UPDATE (I moved my "answer" to here and expanded it for other to find): I ended up using two 5ft x 2ft x 5/8in panels made of pine rather than OSB. They are screwed into three wall studs. I ended up with way less than 100lbs hanging on it.
