Cheryl, We use local office supply companies and material handling companies for our steel shelving. When asking for bids, we also ask them to bid the price of installation. We have found that these companies are usually the ones who know the most about the products and can therefore give you the most information. Also, if you have any problems with the shelving, you have someone local to contact. I would advise against shelving with particle board (as you stated), but I would also advise against Melamine shelves also. Our division has had steel shelving in our library/archive area and collection storage area for several years now, and we have been quite happy with it. If you have any other questions, please feel free to contact me off-list.
