People shop these together but they solve different problems. A dunnage rack is a low, heavy-duty platform that gets bulk goods off the floor. A sheet pan rack (also called a bun pan rack) is a tall frame with slides that holds and transports flat pans of prepped or finished food. Most kitchens need both. The choices are capacity, material, and mobile vs stationary.
A dunnage rack sits low — typically raising product about 6–12 inches — and carries heavy, boxed, or bagged goods: sacks of flour and rice, #10 cans, drums, and boxed frozen product in walk-ins and dry storage. The point is compliance and cleanliness: health codes require food to be stored off the floor (commonly at least 6 inches) so you can clean under it and keep pests and floods away from product. Choose polymer for wet or cold rooms (won't rust, easy to sanitize) and aluminum or stainless where you need maximum weight capacity. Check the rated load — good dunnage racks hold several hundred to 1,000+ lbs — and measure the length; standard widths let you line them along a walk-in wall without blocking traffic. A slatted or louvered top sheds spills and lets air move under bagged goods, while a solid top suits small, tippy containers.
These tall frames take standard 18" x 26" full sheet pans (or steam table pans, if slotted for flanges) on slides. Use them for proofing, cooling, holding line prep, and rolling product from prep to line to service. Capacity is quoted in pan count and by slide spacing.
| Rack size | Typical pan capacity | Best for |
|---|---|---|
| Half / undercounter | 8–10 pans | Cafes, tight lines |
| Full height | 20–30 pans | Most kitchens, bakeries |
| End-load, wide spacing | 12–20 pans | Bulky product, covered pans |
Fixed slides maximize pan count; universal or adjustable slides let you fit both sheet and steam pans and leave room for tall product. Wider spacing means fewer pans but room for covered or piled trays.
Mobile vs stationary: most sheet pan racks come on casters so you can wheel a full load from prep to walk-in to line — a big labor win. If you buy mobile, get at least two locking casters and a rack cover or garment to keep dust and drips off held product. Dunnage racks are usually stationary, but caster-equipped versions exist for bulk you reposition often.
Count the pans your peak prep actually generates and add a rack — running out of pan slots stalls a whole line. Standardize on one pan size so racks, ovens, and your oven or roll-in equipment all share pans. For dry and cold storage shelving beyond dunnage, see local storage requirements, and keep the 6-inch off-floor rule in mind everywhere product touches down. Pair racks with a rotisserie or tilt skillet line to hold and move finished product cleanly.
