5 wall and 4 wall gaylord boxes
Four and five wall gaylords carry the heaviest corrugated loads, cited at 1,500 to 2,200 lb for four walls and 2,000 to 3,000 lb for five, and a used one is worth asking for when it is dry and sound.
The heavy end of corrugated
Past triple wall the numbers climb. Four walls means four layers of flute in each side. Five means five. The board gets thick, the box gets stiff, and the weight it carries rises into the thousands of pounds. Container Exchanger gives common heights of 36 to 41 inches for 4-wall and 36 to 46 inches for 5-wall boxes.
You see them under dense things: cast and machined parts, scrap, resin and regrind, and produce that is heavy per cubic foot. Octagons are often 5-wall for the same reason, since the shape and the walls both fight bulge.
What the ranges look like
| Walls | Cited capacity | Common height | Typical load |
|---|---|---|---|
| 4-wall | 1,500 to 2,200 lb | 36 to 41 in | Parts, heavy produce, regrind |
| 5-wall | 2,000 to 3,000 lb | 36 to 46 in | Cast parts, scrap, dense resin loads |
Those are ranges sellers cite, not guarantees. Board thickness varies from maker to maker, so "5-wall" on its own is not a rating. Always ask for the test or capacity on the specific box.
Short, tall, and what the plant floor needs
Weight and height pull against each other. A tall 5-wall box full of a dense metal part can exceed what a forklift or a floor will take, long before the board gives out. For dense parts, a shorter box, such as the 48 x 40 x 24, often makes more sense than a taller one that you only fill halfway.
Parts makers in Montgomery and Delaware counties tend to ask for full-bottom boxes, since a heavy load sits right on the base. Read the parts and metal page for the whole conversation.
Moisture matters most here. Corrugated loses about half its compression strength when relative humidity moves from 50 to 90 percent, and a thick box takes longer to dry than a thin one.
Used 5-wall: worth the ask
A heavy box that has been through one trip and stayed dry has most of its life left. That is where used stock earns its keep, because the new-box price scales steeply with walls while a good used box does not drop in strength nearly as fast. Run the numbers on the ticket; the break-even trip is the figure to read.
Say the load, the weight, the footprint and the bottom. We tell you what we have and what we do not, and we do not publish prices or minimums here.
The shapes heavy loads take
Heavy does not mean one thing. A pallet of small cast parts concentrates weight in the base and presses on the floor of the box. A load of long steel stock presses outward on the walls. Scrap metal can pierce and tear whatever it touches. A bin of wet compost or dense produce slumps and leans against the sides.
Each of those loads asks something different of the box. The base-heavy load wants a full flap bottom. The outward load wants an octagon or a liner that evens the push. The sharp load wants a heavier inside liner or a thicker board. The slumping load wants an octabin and a lid. Describe the load, not just the weight.
What to weigh before you order
| Question | If yes | If no |
|---|---|---|
| Is the load over 1,800 lb full? | Lean 5-wall | Consider 4-wall or triple |
| Will the box be stacked two high loaded? | Lean 5-wall | Either works |
| Is the load abrasive or sharp? | Lean 5-wall | Either works |
| Does the floor or lift limit gross weight? | Use a shorter box | Taller is fine |
| Will it ride in a humid trailer? | Lean 5-wall, plus dry staging | Either works |
If more than two answers say 5-wall, ask for it. If you are borderline, ask for a Grade A 4-wall and check how it behaves on your first load.
Questions people ask
What is the strongest gaylord?
In corrugated, 5-wall octagons and boxes. Their cited capacity runs 2,000 to 3,000 lb, but check the maker's rating.
Is 4-wall common?
Less than triple wall, but it turns up in used loads from parts and resin plants.
Can I stack 5-wall boxes?
Check the stacking rating and keep them dry. Loaded stacking is a risk when the board is damp.
