The backbone of your warehouse:

Hey there, warehouse and operations managers!

If you’re knee-deep in pallets, forklifts, and tight deadlines, you already know your racking system is the backbone of the whole operation.

But the real heroes? The frames that hold everything steady day after day.

In our new series on racking components (following our popular post on the AS4084:2023 changes), we’re starting right at the base –literally.

Today we cover exactly what pallet racking frames do, the damage they commonly suffer, and the clear repair rules set out in AS4084.2:2023 (the Operation & Maintenance part that applies right across New Zealand).

Let’s keep it simple, practical, and safety-first.

What are pallet racking frames and how are they used?

Pallet racking frames (also called uprights or frames) are the vertical steel assemblies that form the sides of every bay in selective pallet racking.

Each frame is made up of:

  • Two perforated (or slotted) upright posts (the columns)
  • Diagonal and horizontal bracing for rigidity
  • Baseplates bolted to the concrete floor

Their job is straight forward but critical: they carry the compressive load from the beams and pallets above, transfer that weight safely to the ground, and provide lateral stability against forklift knocks and seismic movement.

Without sound frames, the whole system loses its rated capacity – fast. That’s why AS4084.1:2023 (Design) and AS4084.2:2023 (Operation & maintenance) work together to keep them strong and compliant.

Spotting the signs: Common damage types

You don't need to be a structural engineer to spot the warning signs, but you do need to know where to look.

Frames take the hardest hits in any busy operation. The most frequent problems we spot during Rack-Safe inspections are:

  • Forklift impacts: Bent, twisted or dented upright posts (the #1 cause).
  • Bracing damage: Bent bracing (both horizontals and diagonals), or loose bolted connections.
  • Corrosion: Especially on baseplates and lower sections of the uprights, in outdoor or high-humidity areas.
  • Misalignment: Frames leaning out of plumb from overload or floor settlement.
  • Slot elongation or metal tears: This is due to repeated stress over time.

Damage isn't merely cosmetic. Even a seemingly minor dent on a heavily loaded rack can act as a structural time bomb, potentially leading to failure if ignored.

The "Traffic Light" risk system

One of the most helpful aspects of AS4084:2023 (specifically Clause 5.5) is that it simplifies risk assessment into a color-coded system. This helps you prioritize exactly what needs to be done and when.

🟢 Green: Surveillance

Status: Acceptable / Minor damage.

Action: The racking is safe to use, but the damage has been noted. You don't need to unload the rack, but you must monitor it closely during future inspections to ensure it doesn't get worse.

🟠 Amber: Hazardous

Status: Damage requiring action soon.

Action: You have a window of opportunity. The affected section is damaged beyond safe limits but doesn't require immediate isolation.

  • Requirement: You must offload the section and repair the upright within 30 days. If you can't fix it by then, it automatically becomes a Red risk.

🔴 Red: Very Serious

Status: Severe damage / Critical condition.

Action: This is an emergency stop.

  • Requirement: Immediately unload the racking and isolate the area (tape it off). The bay cannot be used again until the upright is repaired or replaced by a competent professional.

Building a culture of reporting

Compliance isn't just about the annual audit; it's about what happens on a Tuesday afternoon when a driver accidentally bumps a frame.

1. Empower your team: Drivers often hide minor accidents for fear of reprimand. Shift the culture: encourage immediate reporting of "oops" moments. It is better to inspect a dent now than deal with a collapse later.

2. The Inspection Cycle:

  • Daily/Weekly: Informal visual checks by your team.
  • Annual: A formal audit by external experts (like Rack Safe Industries) to provide measurements, photos, and official certification.

3. Keep the paperwork: Under the standard, you need a paper trail. Maintain a logbook of all damage reports, photos, severity ratings (Green/Amber/Red), and the repairs performed. This is your proof of due diligence.

PRO TIP straight from the standard: Fit upright protectors (minimum 400 mm high) on all aisle and end frames. They dramatically cut impact damage before it even starts.

Key thresholds

guided by the standard and assessed by a competent person.

  • Any visible bend, twist, or deflection in upright posts
  • Deformed or bent bracing (including loose or missing fixings)
  • Corrosion that compromises section thickness
  • Damaged baseplates and loose anchor bolts

Why this matters for your warehouse

One compromised frame can turn a minor forklift clip into a major collapse risk. Staying on top of frame condition keeps your team safe, avoids downtime, reduces insurance headaches and keeps you fully compliant with WorkSafe expectations.
