Received the shelving on Wed. and found out this is really heavy duty shelving.  It will hold a lot of heavy items.  The only problem I encountered was some paint drippage that had to be sanded down lightly so it would go together easier.  The cross members are easy to put in and will hold a lot of weight. The steel grate for shelves are nice, but not for anything with wheels, unless you get the shelf protector that I haven't purchased yet.  Looks great with my other Gladiator Cabinets.
