Rack/shelf for albums - suggestions please


I just redid my basement and the last detail is to pick up something to store my albums. The last shelf system I had was made of MDF and started to sag from the weight. So, thinking of a rack, maybe 4' > 5' wide, same height to hold roughly 400 albums. Prefer metal but not the cheesy metal racks offered at home depot to be used in a garage.
Any suggestions for some thing industrial grade BUT not too costly?

my Expedit shelve are loaded full, absolutely no sagging. The cubes are the perfect size for LPs too.
FWIW - I tried ULINE steel shelving. I went to Home Depot, bought good quality wood planking, cut it, stained it, and placed it on the the steel shelves. The project was economical and accommodated all of my stereo equipment and two shelves of LPs.
