I made this wood storage rack. I think it'd worked really well so far. I've shoved too many smaller pieces in the three shelves on the left and need to thin it out, next week. I store boards vertically from right to left...short 3', med. 4-6', long 6' + . Plenty of room behind for sheet goods. It has casters to move out to clean...RIGHT but I can blow the stuff out from under with a leaf blower!
Looking at it empty...I had a thought, amazing. I went to the, cold, shop and checked the size of the bins on the left. When I built this, 2 yrs ago, I hadn't started scrolling yet and had no idea a spot to store 12"x12" pieces of Baltic Birch Plywood would be a necessity. I just measured it and it's a little tight. I could either trim off a 1/8" and lay them flat, or empty the top bin and stand them vertically. I'll do the later in the next couple of days!
