Skid: what it is, how it differs from a pallet, and how to spec one

Summary

Strictly, a skid is a pallet with no bottom deck: a top deck fastened to runners, often 3-1/2 × 3-1/2 in (a nominal 4 × 4). Skids carry machinery, crates and heavy loads that are dragged or bolted down. In everyday freight speech, especially in Canada and LTL shipping, skid often just means pallet.

"Skid" and "pallet" are used interchangeably so often that the distinction gets lost. On a spec sheet it matters: a skid has no bottom deck, and that changes how it carries and spreads load. This page covers both the technical skid and the everyday usage.

What is a skid?

A skid is a load platform made of a top deck fastened to parallel runners, with no bottom deck. In the Uniform Standard's terms it is a single-face stringer pallet, usually with heavier stringers. It can be skidded (dragged) across a floor on its runners, which is one reason heavy machinery often ships on skids.

Pallet vs skid: the naming confusion

Usage "Skid" means "Pallet" means
Technical (pallet industry, spec sheets) No bottom deck Top and bottom decks
Everyday freight, LTL, Canada Any pallet or skid Any pallet

When a carrier quotes "per skid", it almost always means per pallet position, whatever is under the load. When you order skids from a pallet shop, say "no bottom deck" to be sure. The pallet vs skid comparison covers this in more depth.

How is a skid built?

The pallet.design skid template is a 48 × 40 in skid for machinery and crate bases:

Component Template value Metric
Runners 3, 3-1/2 × 3-1/2 × 48 in 89 × 89 × 1219 mm
Top deckboards 7, 3/4 in thick, 40 in long 19 mm thick, 1016 mm
Bottom deck none none
Notches none none
Fasteners 2-1/2 in nails 64 mm
Overall height 4-1/4 in 108 mm

Variants:

  • Light skid: 1-1/2 × 3-1/2 in (2 × 4) runners, for light one-way loads.
  • Machinery skid: 3-1/2 × 5-1/2 in (4 × 6) or larger runners, a solid or plywood deck, bolt holes matched to the machine's feet, and chamfered runner ends for dragging.
  • Crate base: a skid that becomes the floor of a wooden crate, often with runners long enough for side entry.

Where are skids used?

  • Machinery, presses, generators and tanks bolted to the deck
  • Crate bases for export and heavy equipment; see metals and machinery
  • Heavy items dragged into position or lifted by crane
  • In-plant parts handling by pallet jack
  • Long or oversize loads on custom-length runners

Pros and limits

Pros Limits
Pallet jacks enter easily (no bottom boards) Two-way entry only
Heavy runners take concentrated loads Runners bear on the floor or load below along narrow lines
Can be dragged or skidded Poor in racking across the width
Simple to build to any size and bolt pattern Runners can roll or split without a bottom deck

Capacity and weight

Weight depends mostly on runner size. A 48 × 40 in skid on three 3-1/2 × 3-1/2 in runners with 3/4 in deckboards uses more lumber in its runners than a GMA pallet uses in its stringers, so expect it to weigh at least as much as a standard pallet, often more, depending on species and moisture. Floor capacity can be high because the runners bear straight on the floor. For machinery, the load is concentrated at the machine's feet, so a skid should be designed for the point loads and bolt positions, not a uniform-load rating. The manufacturer's analysis is authoritative. See pallet load capacity.

ISPM 15

A wooden skid is solid wood packaging and needs heat treatment and an ISPM 15 mark for most export. If the skid is the base of a crate, the crate's solid-wood parts need treatment and marking too.

What drives the cost?

  • Runner size: large timbers cost more per piece than pallet stringers
  • Deck: boards vs plywood; thickness
  • Machining: bolt holes, chamfers, notches
  • Heat treatment
  • Quantity: machinery skids are often small runs

Specifying a skid for a quote

  • Length × width, runner length and overall height
  • Runners: count, size, species, end chamfers
  • Top deck: boards or plywood, thickness, spacing or solid
  • Bolt pattern (hole positions and diameter) or tie-down points
  • Load weight and where it sits (machine feet positions)
  • Handling: forklift, pallet jack, crane, dragging
  • ISPM 15 HT
  • Quantity and delivery location

Frequently asked questions

What is the difference between a skid and a pallet?

In the technical sense a skid has no bottom deck, only runners under a top deck, while a pallet has both decks. In everyday use the words overlap, and many shippers and carriers say skid when they mean pallet.

What size runners does a skid use?

Commonly 3-1/2 × 3-1/2 in (89 × 89 mm, a nominal 4 × 4). Heavier machinery skids use 3-1/2 × 5-1/2 in (4 × 6) or larger timbers.

Can a pallet jack move a skid?

Yes, usually more easily than a pallet, because there are no bottom boards to block the jack's wheels. Entry is two-way, between the runners.

Are skids cheaper than pallets?

A light skid with small runners can be cheaper than a pallet because it has no bottom deck. A machinery skid with large timbers can cost more than a standard pallet.

Does a skid need heat treatment for export?

Yes. A solid-wood skid is wood packaging material under ISPM 15 and must be treated and marked for most international shipments.
