I tried emailing this to the Seattle Metalheads mailing list, but nobody seems to be paying attention. I got a huge pile of steel shelving from the True Value Hardware store in West Seattle, when they got all new fixtures.
I am not selling them, I am giving them away. I am keeping some for myself, but there is still a HUGE pile of shelves.
Anybody interested in good shop shelves, should email me.
The supports are 5 feet tall , but there are vertical extensions to make them taller.
The shelves are all 4 feet wide, and come in many depths.
12", 13", 14", 15", 16". 18", 20", 22".
These can be assembled back to back or along a wall. They do need some form of diagonal bracing betwen the supports. I used 1/8" cable and turnbuckles with great success.
They are all beige.
