48 x 48 x 36 gaylord box

Plants that standardise on 48 x 48 pallets or load into containers by the square. The extra footprint holds about 20% more than a 48 x 40 at the same height.

How it sits on a pallet

A 48 x 48 x 36 box on a 48 x 40 pallet overhangs by 8 in across. Virginia Tech research found that compression strength falls as overhang grows, so Stack Check takes 20% off whenever this size stands on a standard deck. The box covers 16 sq ft of floor and the deck covers 13.33.

What the rating means

The 1,400 lb figure is one maker's listed capacity for a new box. Spread across 48 cu ft, that is 29.2 lb for each cubic foot. A load denser than that reaches the rating before the box is full; a lighter load fills the box first. A used box is rated by grade and place, not by the new figure.

What to watch

On a 48 x 40 pallet this box hangs over by 8 in, and overhang cuts compression strength.

Handling

A 48 x 48 footprint is wider than a 48 x 40 pallet, which makes handling a question of pallets. Plants that run 48 x 48 pallets can use it with no overhang. Plants on 48 x 40 pallets should expect the box to hang over by 8 in, and an overhanging box loses strength.

What fills it

The extra footprint holds about 20% more than a 48 x 40 at the same height. That suits a plant that wants fewer, larger boxes or loads into containers by the square. For dense loads it is the wrong choice, because its rating is lower than the 48 x 40, and the load per square inch of board is higher.

Three loads, worked through

Fill the 48 x 48 x 36 to the brim with something that weighs 20 lb a cubic foot and it holds 960 lb, 990 lb with the box. As Grade A in a heated bay for 30 days that comes out as "do not stack", with 857 lb allowed on the bottom box; as Grade B on a dock it comes out as "do not use at this load", with 464 lb allowed. Suppose the material is 35 lb a cubic foot. A brim-full box then weighs 1,710 lb counting the box. Heated bay, Grade A, a month: "do not use at this load" (857 lb allowed below). Dock, Grade B, a month: "do not use at this load" (464 lb allowed). At 50 lb a cubic foot the full box is 2,400 lb of load. Stack Check gives "do not use at this load" for Grade A in a warm bay and "do not use at this load" for Grade B on a cold dock; the bottom box is allowed 857 lb and 464 lb respectively.

How a used one stands

Below, 3‑wall boxes rated at 1,400 lb filled to the brim with material at 15, 25 and 35 lb a cubic foot, so the loads are 720 lb, 1,200 lb, 1,680 lb. Each is 30 days under load unless the column says 90 days. The 20% overhang cut is included.

What the bottom box is allowed to carry

This is the number behind every stack height: the weight a bottom 48 x 48 x 36 box may carry on its top, after the cuts for grade, place and up to a week under load and for overhang. A box of 1,230 lb (a 1,200 lb load and the box itself) needs this much allowance for each box above it.

Ordering this size

1. Say 48 x 48 x 36 in and the wall count; the same footprint is sold in more than one height.
2. Give the maker's mark if the box has one. The 1,400 lb figure is one maker's new-box listing, not a promise about a used one.
3. Name the pallet. The 48 x 48 footprint does not match a 48 x 40 deck, and the difference costs stack height.
4. Weigh one full box. Past 700 lb, the stack height drops quickly.
5. Say where the stack will stand and for how long: the dock or the heated bay changes the answer more than the grade does.

In a trailer

Freight is a large part of what a gaylord costs, so it helps to know how many 48 x 48 x 36 boxes fit. A typical 53 ft trailer is about 630 x 98 x 108 in inside; the arithmetic is below, and the better layout fits 26 on the floor. Check your own trailer and your own pallets.

In the cold

The wider footprint spreads the load over more board, which helps, but on a 48 x 40 pallet the overhang takes 20% back in Stack Check. In the cold, plan as you would for the 48 x 40 x 36 and then subtract for the overhang.

New or used at this size

This is a less common used size, so ask about history and look at the corners: a box with a wide footprint can rack out of square, and a racked box stacks badly. Grade B with square corners beats Grade A that is out of true.

Who orders it

Plants that standardise on 48 x 48 pallets, container loaders who want to use every square inch, and packaging users with wide, flat loads.

Against its neighbours

Compare it with the 48 x 48 x 48 if you want a larger cube, and with the 48 x 40 x 36 if you run standard pallets. The question to ask first is which pallet your dock actually uses.

The 48 x 48 footprint rewards a plant that has already settled its pallet question. If every pallet in the building is 48 x 48, the box is a natural fit and the overhang cut does not apply. If the building runs 48 x 40, the box is a poor fit and the 8 in of overhang will cost stack height. Settle the pallet first, then the box, and the quote follows.
