What Is a Demountable Post Pallet (Derack) and When Should You Use It Instead of Wooden Pallets?

Demountable Post Pallet (Derack)

What a Demountable Post Pallet Is — and When to Use It Instead of Wooden Pallets

Derack is a structural, returnable steel carrier: a base frame plus removable posts. It transfers the load down through the posts to the floor, so the bottom layer sits at zero compression — then the posts come out and the empty frames nest for return.

A wooden pallet is a flat deck that stacks cargo on top of cargo: every upper tier presses on the tier below, so the bottom layer crushes, settles and traps moisture. A demountable post pallet works the opposite way. The removable posts form a rigid cage; each loaded tier rests on the post ledges, and the posts carry the weight straight to the ground. The cargo at the bottom carries none of the upper load. That single change — from cargo-on-cargo to structure-borne load — is why Derack is used for bagged feed and fermentation stock, tyres, pipe and bar, fabric rolls, cold-chain and export where crush, moisture and quarantine are the real risks. It is not a cheap wooden-pallet substitute and it is not a bolted fixed rack: it is the movable, nestable middle option. For the full stack-rack system see our Derack post pallet and stack rack systems, and for space-constrained 3PL operations our 3PL vertical-density solution.

  • Structural load path: upper tiers transfer weight through the posts to the floor, not onto the cargo below.
  • Bottom layer at zero pressure — no crush, no settle, no moisture trap for bagged or carton goods.
  • Removable posts: one base frame serves many cargo programs; posts detach for compact return.
  • Nests 75–80% smaller when empty, cutting backhaul and empty-storage cost.
  • Steel body is ISPM 15 exempt — no fumigation, no stamp, no quarantine hold for export.
Configuration options

Three common ways to build the same platform

Open structure for long cargo
Long-material program

Open structure for long cargo

Use when pipe, bar, profiles or other elongated materials need a clear support path and stable handling route.

Typical fit: long-material and vertical storage
Engineering focus: span, centre of gravity, loading sequence
Side-protected or boxed-material setup
Protected cargo program

Side-protected or boxed-material setup

Choose a side-protected version when cartons, bundles or load surfaces need extra containment during turnover.

Typical fit: boxed materials and mixed packing formats
Engineering focus: side protection, access, handling clearance
Minimal frame for return logistics
Base platform only

Minimal frame for return logistics

When the project values return ratio and compact storage more than enclosed protection, the base platform stays simple and nests efficiently.

Typical fit: returnable transport packaging programs
Engineering focus: nesting, post count, empty handling
Why Derack

Why Derack, and when not to choose it

1

Structural, not cargo-on-cargo

Because the load is borne by the posts, the bottom layer is not compressed. That removes the crush and moisture-trap failure mode of floor-stacked wooden pallets.

2

Return logistics

Remove the posts and the base frames nest into a compact column. Return-volume saving is typically 75–80%, which is what makes Derack a reusable RTP asset rather than a one-way pallet.

3

Coating is project-confirmed

Surface treatment is selected per project — hot-dip galvanizing, cold-dip galvanizing, or a composite galvanize-plus-powder route — confirmed against your indoor, outdoor, cold or humid duty.

4

Know when not to use it

If your only goal is maximum fixed-location selective picking density and you do not need mobility or return nesting, a beam rack can be the better fit (see our selective racking and beam-rack comparisons).

How we work

From load case to delivery

1

Send the cargo data

Share cargo type, dimensions, unit weight, total quantity, stack-height target, and whether the load is pipe, bar, panel, boxed or mixed goods.

2

Define the structure

We check post count, base span, access path, side protection, surface treatment, and whether the unit must nest after the posts are removed.

3

Confirm the engineering choice

We align the load case with the correct stacking envelope and finish option, then finalise the project drawing for approval.

4

Build and support the rollout

After approval, production follows the agreed specification, and the shipment plan is arranged around handling and return logistics.
