Load & capacity

Three numbers.
Only one of them
is the small one.

Pallet failures are almost never a surprise to an engineer. They happen because somebody read a static load rating on a spec sheet and racked the pallet unsupported. These three figures are not interchangeable, and the gap between the largest and the smallest is usually a factor of three.

Static: Floor-stacked, at rest
Dynamic: In motion, lifted
Racked: Unsupported span
Safety factor: Apply your own

Match a pallet to a load

Give us the load weight, how it's handled and whether it racks. We'll name the grade and construction that carries it, and tell you if the cheaper one is enough.

No phone tag. No sales sequence. One reply from one person.

Definitions

What each rating actually measures

Read these once properly and you will never specify a pallet incorrectly again.

Static loadDynamic loadRacked load

The biggest number, and the least useful

Static load is the maximum weight a pallet can support while resting on a flat, continuous surface — the floor, or another pallet in a stack. The floor carries most of the load path, so the pallet is barely working.

This is the figure most sales sheets lead with, because it is the most flattering. It only applies to floor stacking and bottom-of-stack positions.

Grade	Static
A / Premium	4,600 lb
#1 recycled	4,000 lb
#2 recycled	3,200 lb
New hardwood	5,000+ lb
EPAL 1	8,800 lb

The number for daily handling

Dynamic load is the maximum weight a pallet can carry while being lifted and moved by a forklift or pallet jack. The load path runs through the stringers or blocks and the deck between the forks, so the pallet is genuinely structural here.

For most warehouse operations this is the rating that matters. If you only check one number, check this one.

Grade	Dynamic
A / Premium	2,800 lb
#1 recycled	2,500 lb
#2 recycled	1,800 lb
New hardwood	3,000 lb
EPAL 1	3,300 lb

The small number that collapses racking

Racked load is the maximum weight a pallet carries when spanning two beams with no support underneath — the deck boards and stringers are in pure bending, and deflection accumulates over weeks of storage.

It is typically a third of the static figure. A plugged #2 pallet should not be racked unsupported at all, and we grade accordingly rather than quietly hoping.

Wire mesh decking or support bars change the calculation entirely: with full deck support, the static figure becomes relevant again.

Grade	Racked
A / Premium	1,800 lb
#1 recycled	1,500 lb
#2 recycled	Not advised
New hardwood	2,200 lb
EPAL 1	2,200 lb

Variables

Six things that change the rating in your building

Load distribution. A uniformly distributed load is the test condition. Point loads — machinery, drums, a single dense case — concentrate stress and can halve the usable capacity.
Storage duration. Wood creeps. A pallet that holds a racked load fine for a week may deflect noticeably after three months. Long-term storage deserves a deliberate safety margin.
Moisture. Wet wood loses stiffness fast. Cold-store and outdoor storage both reduce effective capacity; this is why we keep stock under cover.
Span direction. Racked across the stringers is far weaker than racked along them. Orientation in the bay is not cosmetic.
Deck support. Wire mesh or support bars transform racked behaviour. If you have them, say so — it may let you use a cheaper grade safely.
Fastener condition. Loose nails redistribute load unpredictably. This is exactly what our grading line is looking for.

Apply your own safety factor

We publish observed capacities, not marketing maxima. Standard practice is to apply a factor of at least 1.5 for dynamic handling and 2.0 for long-term racked storage, and to specify at the resulting number rather than at the published one.

If a load is genuinely near the limit of a grade, buy the grade above it. The difference in price is trivial next to the cost of one collapsed bay — and if you tell us the weight, we will say so plainly. See grade definitions.

All three ratings together, 48×40 footprint, uniformly distributed load.
Grade	Static	Dynamic	Racked
A / Premium	4,600 lb	2,800 lb	1,800 lb
#1 recycled	4,000 lb	2,500 lb	1,500 lb
#2 recycled	3,200 lb	1,800 lb	Not advised
Core / mixed	Unrated	Unrated	No
New hardwood	5,000 lb	3,000 lb	2,200 lb

Testing

Published capacities derive from ISO 8611-style test methods — incremental loading to deflection limits on sample decks from each grade lane, repeated quarterly. We are a pallet yard, not a certified laboratory, and we say so: treat these as well-evidenced operating figures rather than certified design values.

Field questions

Asked by people with a rack plan in hand

Can I rack recycled pallets at all?

Yes — #1 grade with full-length stringer repairs, at a derated figure with a safety factor. Plugged #2 pallets, no.

Does wire decking let me use a cheaper pallet?

Often, yes. With continuous deck support the pallet stops spanning and the static figure applies. Tell us if you have it.

Why is EPAL rated so much higher?

Nine blocks, heavier timber and a prescribed nail pattern. It is a genuinely stronger pallet — and about 7 kg heavier per unit.

What about drive-in racking?

Drive-in rails support the pallet along its stringers continuously, which is kinder than beam racking. Confirm the rail spacing matches your footprint.

How do I tell if a stored pallet is deflecting?

Sight along the deck. Visible sag means it is overloaded or creeping; pull it and send it for repair.

Applying the figures

From a load weight to a specification

Published capacities are observed operating figures under a uniformly distributed load. These are the adjustments to make before you specify anything.

Multiply the published capacity by the factor, or divide your load by it — either way, specify at the adjusted number.
Condition	Adjustment	Why
Uniformly distributed load	× 1.00	The test condition
Point loads, machinery, drums	× 0.50–0.70	Stress concentrates between boards
Long-term racked storage	× 0.50	Wood creeps; deflection is permanent
Racked across the stringers	× 0.40	Deck boards bend with no support
Wire mesh or support bars fitted	Static figure applies	The pallet stops spanning
Cold store or outdoor storage	× 0.85	Wet wood loses stiffness
Loose fasteners, aged pool	× 0.80	Load redistributes unpredictably
Dynamic handling, safety factor	× 0.67	Standard practice is 1.5 on the load

Worked example

Load weight: 1,800 lb
Handling: Forklift, daily
Storage: Racked, unsupported, 3 months
Required racked capacity: 1,800 × 2.0 = 3,600 lb
#1 recycled racked figure: 1,500 lb — insufficient
New hardwood racked figure: 2,200 lb — still insufficient
Correct answer: Add wire decking, or use EPAL

This is the calculation that prevents the collapsed bay. It takes two minutes and almost nobody does it.

Tell us these three things

What it weighs, fully loaded
How it is handled: forklift, jack, conveyor, or hand
Whether it racks unsupported, and for how long
Whether you have wire decking or support bars
Whether the load is uniform or concentrated

Species in our intake, and how they behave

Densities and Janka figures are published wood-science values; the behaviour column is sixteen years of our own grading notes. Our intake is oak-dominant mixed hardwood.
Species	Group	Density (lb/ft³)	Janka hardness	Behaviour in a pallet
White oak	Hardwood	47	1,350 lbf	Our backbone: holds fasteners superbly, heavy, very durable
Red oak	Hardwood	44	1,290 lbf	Slightly more porous than white; excellent deck boards
Hickory	Hardwood	51	1,820 lbf	Hardest of our intake; superb stringers, splits if nailed dry
Maple	Hardwood	44	1,450 lbf	Clean, pale, dimensionally stable; good for upcycled tops
Ash	Hardwood	41	1,320 lbf	Tough and flexible; forgiving under impact
Poplar	Hardwood	29	540 lbf	Light hardwood, weaker fastener grip, fine for one-way
Southern yellow pine	Softwood	35	690 lbf	Common in new softwood builds; resinous, holds nails well
Spruce / fir	Softwood	27	510 lbf	Lightest option; loosens soonest under repeated handling

Moisture targets by application

Dryness is the single biggest determinant of recycled pallet quality — more than grade, species or board count.
Application	Target moisture	Why
Food distribution	≤ 19%	Mould risk, not strength; covered storage mandatory
Pharmaceutical / clean areas	≤ 15%	Documented dryness, often new material
General warehouse and racking	≤ 19%	Fastener grip and creep resistance
Cold chain	≤ 15% at dispatch	Condensation cycling through the dew point
Export, heat-treated	≤ 19%	Post-chamber typical; bark-free is the hard rule
Upcycled furniture stock	8–12%	Conditioned indoors two weeks before machining
Field and agricultural use	No target	Weather governs; buy #2 and expect it

Fasteners — two percent of the cost, most of the service life

Specify the fastener and the count per board-stringer intersection, not just the board count.
Fastener	Length	Shank	Withdrawal resistance	Where we use it
Helical-thread nail	2½"	Twisted, thread-cutting	High, survives moisture cycling	Standard on every new build and repair
Annular-ring nail	2¼"–2½"	Barbed rings	Highest	Lead boards and heavy racked specifications
Smooth-shank nail	2"–2½"	Plain	Low, drops as wood dries	Not used — the reason old pallets loosen
Screw-shank nail	2½"	Coarse helix	High	Block pallets and thick stringers
Staple	1¾"	Crown wire	Low in hardwood	Not used here; acceptable in softwood one-way pallets

Handling and rack dimensions

Measure your own equipment before specifying a pallet. These are the values that decide whether a footprint works in your building.
Dimension	Typical value	Note
Fork length	42"–48"	Must not protrude beyond the far side of a 48" pallet
Fork width	4"–6"	Wider forks spread load across deck boards
Fork thickness	1½"–2"	Determines minimum pallet entry height
Fork spread, GMA entry	24"–27" centres	Between the stringers of a three-stringer pallet
Pallet-jack wheel path	6½" clear	Why notched stringers do not admit jacks
Minimum entry height	3½"	A crushed bottom deck blocks the forks entirely
Rack beam span, two pallets	≥ 96" clear	For two 48×40 pallets, 40" face out
Flue space, back to back	≥ 6"	Most fire codes; check your jurisdiction

The life of one deck, stage by stage

Durations are medians from our line records and the Passport programme; the population is survivor-biased and we say so.
Stage	Typical duration	What happens	Carbon position
Timber to pallet	Weeks	Sawn, nailed, often shipped wet	12.6 kg CO₂e embodied
First life	2–4 years	Hardest service; lead board usually fails	Credit begins at reuse
First repair	2 minutes	Lead board replaced with salvaged stock	+1.8 further lives on average
Second to fifth life	6–12 years	Grading, companions, re-nailing, re-grading	11.6 kg CO₂e avoided per cycle
Structural retirement	—	Stringers rotted or deck beyond rebuild	Stored carbon still retained
Repurposed	Decades	Collars, crates, table tops, cladding	Carbon stays in the material
Fiber	1–3 years	Mulch or bedding, then soil	Released slowly
Thermal	Immediate	Boiler-grade chip	Released at once — last resort

A pallet is only downgraded for a defect a grader can name out loud. If it is not on this list, it is not a reason to move a pallet between lanes.

Glossary — thirty terms worth knowing

Core: A used pallet bought for grading — the currency of the industry.
Deck board: Any board on the top or bottom face of a pallet.
Lead board: The outermost deck board at each end; absorbs every fork entry.
Stringer: The long member running the length of a stringer pallet; usually three.
Stringer board: On a block pallet, the board that ties the blocks together.
Block: One of the nine supports in a block pallet.
Notch: The cut-out in a stringer that creates four-way fork access.
Chamfer: A bevel on a lead board's lower edge to ease fork entry.
Companion: A full-length board nailed alongside a damaged stringer. A strong repair.
Plug / scab: A short piece fixed over a break. A weaker repair; #2 grade here.
Re-nail: Restoring the fastener pattern on a loose but intact pallet.
Regrade: Moving a pallet between grade lanes after inspection.
Down-cut: Re-cutting a larger deck into a smaller footprint.
Static load: Capacity at rest on a flat, continuous surface.
Dynamic load: Capacity while being lifted and moved.
Racked load: Capacity spanning beams with no deck support. Always the smallest figure.
Unit load: Pallet, product and wrap considered as one structure.
Overhang: Load or deck projecting beyond its support. The leading cause of rack failure.
Flue space: The gap between back-to-back rack bays; six inches minimum in most codes.
GMA: The Grocery Manufacturers Association 48×40 specification.
EPAL: The licensing body for the European 1200×800 block pallet.

Diversion rate: Share of intake kept out of landfill. Ours is 100%.
Reuse rate: Share of intake that leaves as a pallet. Ours is 94%.

Still wondering?

Eight questions that arrive most weeks. The full set lives on the FAQ page, and anything missing can go straight into the form at the top of this page.

Ask the yard

Asked most weeks

What is your minimum order?

100 pallets for metro delivery, 50 for a pickup of material you are selling us, a full trailer for out-of-region freight, and no minimum at all if you collect from the yard.

How quickly can you deliver?

Recycled stock in standard grades is usually same or next business day inside the metro. New builds run 3–7 business days; heat-treated 2–5.

Do you pay for used pallets?

Yes, for sound cores and most odd sizes. Genuinely scrap or contaminated wood carries a removal fee instead, and the offer always separates the two.

Can recycled pallets be used for export?

Only with a valid ISPM-15 heat-treatment mark. We re-treat and re-stamp recycled decks in our own registered chamber wherever the regulation allows it.

Are pallet grades standardised?

No. There is no enforced national standard, which is why we publish thirteen named defects and put the grade definition in writing before any contract.

Why is there no phone number?

The yard is loud and pallet enquiries are specific — counts, sizes, grades, postal codes. Written requests get accurate answers, usually the same business day.

Do you serve my area?

Routinely within 300 miles of St. Louis. Past roughly 950 miles the freight cancels the carbon benefit of reuse, and we will say so rather than quote it.

What happens if a load disappoints?

Tell us the same day. We re-grade, replace or credit, and we examine the lane that produced it. Grade disputes are information, not arguments.

Next step

Tell us what it weighs

Weight, handling method and whether it racks. We'll specify the cheapest pallet that is genuinely safe for it.
