How much weight can office bookcase shelves hold?

Commercial bookcase shelves are rated at 50–100 lbs of distributed load per shelf — enough for 10–20 standard binders (about 4–5 lbs each) with room to spare. Steel shelving units carry much more, often 200+ lbs per shelf. FindOfficeFurniture.com includes load ratings in all product specs — call 888-719-4960 to confirm capacity for heavy-duty applications.
