Industry notes · Manufacturing

Heavy loadswant honestratings.

Manufacturing is where pallet specifications stop being a procurement exercise and start being an engineering one. Castings, coils, drums and subassemblies concentrate load in ways a uniformly distributed test figure does not describe, and the gap between a static rating and a racked one is where accidents live.

Typical grade: #1 recycled or new
Construction: Block or 4-stringer
Common need: Custom footprints
Load type: Point loads, racked

What matters here

Four priorities we design around

Every sector thinks its pallet requirements are universal. They are not — these are the four that actually differ for this one.

Point loads, not test loads

A machined part sitting on four feet is nothing like a uniformly distributed test load. We add deck boards rather than thickness, and we say when a block pallet is the honest answer.

Racked capacity with a margin

Racked ratings are typically a third of static. We publish ours and recommend a 2.0 factor for long-term storage, which sometimes means buying the grade above.

Dimensional repeatability

Automated lines and robotic palletisers need consistency that recycled stock cannot guarantee. This is one of the few genuine cases for new builds.

Repair instead of replace

Industrial duty cycles destroy lead boards. A monthly bench or on-site crew day keeps a pool alive for years.

In practice

Specify the handling, not the weight

The most common specification error we see in manufacturing is a purchase order that states a weight and nothing else. Weight alone cannot tell us whether you need a 3,200 lb pallet or a 1,500 lb one, because the answer depends entirely on whether that weight sits on a floor, moves on forks or spans two beams.

Tell us all three — the weight, the handling method and whether it racks — and we can usually specify something cheaper than you expected, with a safety margin you can defend in a meeting.

Static: floor-stacked and bottom-of-stack positions.
Dynamic: lifted and moved; the number that matters daily.
Racked: unsupported span; typically a third of static.
Wire decking changes everything — tell us if you have it.

Where custom footprints genuinely pay

Manufacturing is the one sector where bespoke pallets frequently earn their cost, because product geometry is fixed and a standard footprint can waste a third of the deck. Re-cutting recycled decks to a custom size captures most of that saving at a fraction of the carbon of a new build.

We quote at least two routes on every custom enquiry — re-cut and new — so the cost of the greener option is visible rather than assumed.

Typical specification for manufacturing customers.
Load profile	Recommendation
Under 1,500 lb, floor-stacked	#1 recycled, 6-board deck
1,500–2,500 lb, handled	#1 recycled, 7-board deck
Racked, under 1,500 lb	#1 with full-length companions
Racked, 1,500–2,200 lb	New hardwood or EPAL
Point loads / machinery	Custom build, extra deck boards
Automated handling	New, built to jig

Sector questions

Can I rack recycled pallets?

#1 grade with full-length stringer companions, yes, at a derated figure with a safety factor. Plugged #2 pallets should not be racked unsupported.

Do you build to a drawing?

Yes, with a build sheet confirmed in writing and a free prototype on runs above 500 units.

Can you repair on our site?

For pools above roughly 1,500 pallets it is usually cheaper to send a two-person crew to you than to truck the wood twice.

Before your first manufacturing order

Measure one rack bay: beam-to-beam clear span, depth and clear height.
Weigh ten pallets from your current pool and write down the average.
Decide whether anything racks unsupported — it changes the grade.
Note your gate and dock hours, and any lift or doorway on the route.
Ask for the twenty-pallet sample. It settles grade expectations in an afternoon.

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

Standards that actually govern a pallet

Only ISPM-15 is legally mandatory, and only for export. Everything else is a specification you can choose to be held to.
Standard	Issued by	Covers	Why it matters to you
ISPM-15	IPPC / FAO	Phytosanitary treatment of wood packaging	Mandatory for export; 56 °C core for 30 minutes, marked
ISO 6780	ISO	Principal pallet footprints	Defines the six international sizes, including 1200×800
ISO 8611	ISO	Pallet test methods and performance	The basis of static, dynamic and racked load figures
ASTM D1185	ASTM	Test methods for pallets and skids	North American equivalent test battery
GMA specification	Grocery Manufacturers Assoc.	48×40 four-way notched stringer pallet	What 'GMA' means when stated properly

NWPCA uniform standard	NWPCA	Recycled pallet grading practice	The nearest thing the recycled market has to a rulebook

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
