36 x 36 x 36 in gaylord boxes
The 36 x 36 x 36 inch gaylord is a 27 cubic foot cube, tested at 1,100# triple wall and rated by one maker at 1,200 lb, and it is also the size listed for UN-rated hazmat gaylords.
The numbers
36 x 36 x 36 in gives you a 36 x 36 footprint. Its volume works out to 27 cubic feet (36 x 36 x 36 = 46,656 cubic inches, divided by 1,728 cubic inches per cubic foot).
| Detail | Value | How it is figured |
|---|---|---|
| Footprint | 36 x 36 in | Outside, as the trade quotes it |
| Height | 36 in | Set-up height |
| Volume | 27 cu ft | 36 x 36 x 36 / 1,728 |
| Rated capacity | 1,200 lb | triple wall, one maker; tested 1,100# triple wall |
| Capacity per cubic foot | 44.4 lb | 1,200 / 27 |
| Pallet | 48 x 40 in standard | This footprint fits inside a standard 48 x 40 pallet, leaving 12 in along the 48 in side and 4 in along the 40 in side uncovered. |
What this size carries here
This is the small cube of the family. At 36 inches on each side it holds 27 cubic feet, enough to move a load of small parts, ingredients or packaged goods by the pallet but small enough that two people can reach the bottom. Density works out to about 44 lb per cubic foot on the rating, higher than the standard box, so it is a good match for heavier, compact goods.
The 36 x 36 x 36 is also the size listed for UN-rated corrugated hazmat gaylords, which carry dangerous goods under UN packaging rules. Shipping hazardous waste or dangerous goods in bulk boxes is tightly regulated, and a used box is not UN-rated unless certified. We do not chase hazmat buyers and will not describe a used box as meeting UN rules.
In ordinary use, you find it at pharmacies of the supply chain, specialty chemical distributors and food ingredient makers across Montgomery and Chester counties, where loads are expensive per pound and box size is chosen for handling.
Load arithmetic
For the 36 x 36 x 36 in box, the deck of a 48 x 40 pallet is 1,920 square inches. The footprint covers 1,296, or 68 percent of it. Weigh what you plan to put in, then see where you land against the 1,200 lb rating (triple wall, one maker; tested 1,100# triple wall).
| Share of rating | Pounds | Pounds per cubic foot | What it means |
|---|---|---|---|
| 25 percent | 300 | 11.1 | Light |
| 50 percent | 600 | 22.2 | Comfortable |
| 75 percent | 900 | 33.3 | Working load |
| 90 percent | 1,080 | 40 | Near the limit |
Stay in the first three rows for a used box. A box below Grade A has already given up some of its rating.
The same volume in other units
Growers, plants and carriers each count in different units, so here is 36 x 36 x 36 in in the ones they use. A bushel is 1.2445 cubic feet, a cubic yard is 27, a US gallon is 0.1337 and a liter is 0.0353. Fill level matters: a box filled to 32 of its 36 inches holds 24 cubic feet, because the top four inches are for flaps and settling.
| Unit | Number | Conversion used |
|---|---|---|
| Cubic inches | 46,656 | 36 x 36 x 36 |
| Cubic yards | 1 | 27 / 27 |
| US bushels | 21.7 | 27 / 1.2445 |
| US gallons | 202 | 27 / 0.13368 |
| Liters | 765 | 27 / 0.035315 |
| Floor area | 9 sq ft | 36 x 36 / 144 |
Asking for it
Tell us the load, the weight and whether anything about the goods is regulated. If it is, say so at once. For ordinary freight we will tell you which wall count and bottom to use.
One thing to watch
A small cube on a 48 x 40 pallet leaves a lot of pallet empty. Two boxes side by side cover 72 x 36 on a pallet that is 48 x 40, so plan how they are arranged.
