How much weight can a gaylord box hold?
A gaylord holds roughly 800 to 1,200 lb at two walls and 2,000 to 3,000 lb at five, but those are ranges sellers cite, and the maker's rating for the exact box is what counts.
The ranges, then the caveat
| Walls | Cited capacity | One catalog's rating | Common height |
|---|---|---|---|
| 2-wall | 800 to 1,200 lb | 275#/ECT-48 | 30 to 36 in |
| 3-wall | 1,000 to 1,600 lb | 1100#/ECT-90 | 34 to 40 in |
| 4-wall | 1,500 to 2,200 lb | Not listed | 36 to 41 in |
| 5-wall | 2,000 to 3,000 lb | Not listed | 36 to 46 in |
The caveat: wall-count ratings are ranges sellers cite, not guarantees. Individual wall thickness varies, so wall count alone is not always reliable. For a figure you can check, one maker lists a 36 x 36 x 36 inch triple-wall box tested at 1,100 pounds (see the sources below). The only rating that counts is the maker's for the box in front of you.
Test and capacity are not the same thing
You will see "1100#" and "ECT-90" on a box stamp. Those describe the board, measured in a lab. The edge crush test (ECT) presses a strip of board on its edge until it fails; burst tests push a diaphragm through it. Capacity is a different claim: the weight the finished, loaded box can carry. One maker rates a 48 x 40 x 36 triple wall at 1,500 lb capacity; another lists the 46 x 38 x 36 octagon at a 1,300 lb test and 2,200 lb capacity.
A used box has not been retested. A Grade A box that stayed dry is close to its rating. A Grade B box has given up an unknown amount. When in doubt, load it lighter.
What knocks the rating down
- Humidity. Corrugated loses about 50 percent of its compression strength when relative humidity rises from 50 to 90 percent. Stacking strength often falls to about 50 percent of potential above 85 percent.
- Time under load. Boxes held under load in humid conditions can lose nearly 45 percent of strength after 90 days.
- Pallet overhang. Strength decreases as the box overhangs the pallet; Virginia Tech found overhang magnitude, box perimeter and board type to be significant predictors.
- Cold and condensation. Brittle board in the cold and moisture when it warms.
- Damage. Creases, crushed corners and torn flaps.
Do the check yourself
- Weigh a full box on your floor scale; subtract the pallet for the load.
- Divide the load by the volume: pounds per cubic foot. The sizes table shows what each size is rated for.
- Compare to the rating, with a margin of at least a fifth.
- If you are over, step up a wall, or step down in height.
Dense loads belong in short boxes with full bottoms; see parts and metal.
Questions people ask
How much weight can a gaylord box hold?
Roughly 800 to 3,000 lb depending on walls, as sellers cite; check the maker's rating.
Are used boxes weaker?
Lower grades are. A clean, dry Grade A box is close to new.
Does a full flap bottom hold more?
It can carry loads that a partial bottom cannot without a pallet.
