I see you've been given a link for the Sagulator web site. If it determines
you will get too much sag, there are ways of adding strength. Think of an
"I" beam. Adding a strip of wood on the front that is vertical add
considerable stiffness. Adding a back and attaching the shelves to it add
too.

It might be cheaper and less work to get steel pre made shelves

Thanks for the suggestions, the sagulator is a great resource. Looks like
3/4 plywood with 2" edging front and back will work nicely.
I checked into steel shelving but the cost (discounting my labor) was higher
and couldn't find anything flexible enough to fit the space I'm using.

Consider some of the heavy duty shelving at Costco or Sam;s Club. The
product looks good, and will easily hold the weight you anticipate.
Other sources for that kind of shelving are salvage from store
remodelings, often seen on Craigslist or classifieds. Makes sense if
your talking storage and not furniture.

JD:
I'm generally with the metal crowd. Check industrial surplus
outfits, school surplus liquidation people, take a flyer on
Habitat for Humanity stores and try Craig's List. If the first 3
can't immediately help, ask for their suggestions. Used office
furniture outlets are often ludicrous. Most industrial/commercial
auctions are not good pricewise.
Occasionally you will find one with huge quantities of shelving or
lateral file cabinets where you can
make a buy but you better be in no hurry and live in an
urban/suburban locale. Condition and sufficient units of uniform
appearance will be your problem when dealing with used material,
along with the constant of price .
Plywood on the back of a wood unit is great. So are shelves inset
into that backing. On the front,
if you can find a reasonable surplus source for heavier threaded
rod, you can run that through drilled
holes near the front edge using some of the databases you have to
elect intervals against
sag. Washers and nuts will go on either side of the shelves to tie
them into the rod. If this is
a decorative effect you fancy, you can also put carefully sawed
sections of various kinds of tubing
over the rod between the shelves for the coverup pillar effect.
The ways you can address this
problem are open given imagination and a source of reasonable
materials.
Good luck.
Regards,
Edward Hennessey
