The poles are the diameter of my pinky finger and come in 4 sections. Top has a plastic cap, bottom has a threaded hole for the adjustable leveling feet, and 2 middle sections - uses a double threaded connector to attach together. Bought 2 to combine into a taller unit. Gets a bit wobbly above 5 ft due to the pole size. Wish it used the same sized poles as the standard more industrial wire shelving. Shelves are recessed so things won't roll off (might miss that fact in the pictures) and the gauge of steel is appropriate. The bottom shelf has an extra foot to support additional weight that requires it be set at the height shown in the picture (you can remove the foot if you want to adjust the shelf). As the feet stick out a bit on the floor you can't get this flush against the wall which is a bit annoying: it needs to be that way for stability. It is what it is and it does it well.
