Selective pallet racking is the most common way to store pallets in Australian warehouses. Every pallet sits in its own position and can be reached by forklift without moving any other pallet, which is why it is the default choice for businesses that stock many different products.
This guide explains how selective racking works, what its sizes and load ratings mean, how it compares with denser systems and what to check before you buy for a Sydney site. If you are still weighing up systems, start with our guide to choosing a pallet racking system for your Sydney warehouse.
The short version
- Selective racking stores pallets one deep, with direct access to every position
- It suits many product lines, mixed picking and layouts that change over time
- It uses more floor space per pallet than double deep or drive-in racking
- Load ratings are set per beam level and per bay, and must be shown on signs
- Racking needs anchoring, collision protection and a formal inspection at least every 12 months
What is selective pallet racking?
Selective pallet racking, also called adjustable or single deep pallet racking, is a steel frame and beam system that stores pallets one deep along an aisle. Because no pallet sits behind another, a forklift can retrieve any pallet at any time. That direct access is what the word selective refers to.
Each bay is built from two upright frames joined by pairs of beams, and pallets rest across the beams at each level. Beam positions can be moved up or down the uprights in set steps, so levels can change as your pallet heights change. The main components are:
- Upright frames: vertical posts joined by bracing, fixed to the floor through footplates
- Beams: horizontal members that lock into the uprights and carry the pallets
- Safety clips or locking pins: stop beams lifting out of the uprights
- Footplates and anchors: fix each frame to the slab
- Accessories: wire mesh decking, pallet backstops, upright protectors and end-of-rack protectors
What are the advantages of selective pallet racking?
The main advantage is access. Every pallet can be picked without moving another, so selective racking suits warehouses with many product lines and frequent picking. It also works with standard forklifts, is simpler to install than deep-lane systems, and can be adjusted or extended as your stock changes.
- Direct access to every pallet. Picking never involves shifting other pallets, which speeds up mixed orders and stock counts.
- Any rotation method. Every position is reachable, so you can run first in, first out or any other order through your procedures or warehouse system.
- Standard equipment. Counterbalance forklifts and reach trucks both work, as long as the aisle is sized for the truck.
- Adjustable and expandable. Beam levels can be moved to suit new pallet heights, and bays can be added along a row later once the supplier confirms the load ratings.
- Simple to maintain. Damaged beams, clips and uprights can be replaced individually with approved parts.
What are the disadvantages of selective racking?
The trade-off is floor space. Selective racking needs an aisle beside every pair of rows, so it stores fewer pallets in a given footprint than double deep, drive-in or push-back systems. If you hold large quantities of the same product, a denser system may cost less over time.
In Sydney, where industrial rents are high, that lost floor area has a real cost. Two things usually recover space without changing system: racking up to the limit set by sprinkler clearance, and using reach trucks so aisles can be narrower.
How does selective racking compare with other pallet racking systems?
Selective racking offers the best access and the lowest density. Double deep, drive-in, push-back and pallet flow systems store more pallets in the same floor area by storing them deeper, but each gives up some direct access. Many sites use selective racking for the pick face and a denser system for bulk stock.
| System | Pallet access | Storage density | Stock rotation | Best for |
|---|---|---|---|---|
| Selective | Every pallet directly | Standard | Any order | Many product lines, mixed picking |
| Double deep | Front pallet directly, rear pallet after the front is moved | Higher | Limited by the two-deep position | Fewer lines with several pallets each |
| Drive-in | Forklift drives into the lane | Highest | Last in, first out | Large quantities of uniform stock |
| Push-back | Front pallet of each lane | High | Last in, first out | Several pallets per line with more access than drive-in |
| Pallet flow | Front of each lane | High | First in, first out | Fast-moving or date-sensitive stock |
As a rough guide, double deep can add up to about 30 percent more pallet positions than selective in the same footprint. The catch is that the rear pallet cannot be reached until the front one is moved, and the system needs a truck with extended reach.
How much weight can selective pallet racking hold?
There is no single figure. Capacity is rated per beam level and per bay, and depends on the beam profile and length, the upright section and height, and the spacing of the levels. Two limits must never be exceeded: the maximum unit load and the total rated capacity of each bay.
Published beam tables show how much the profile matters. For a beam of about 2.7 m, one Australian supplier’s table lists ratings from 600 kg to 1,500 kg per pallet space, depending on the beam section.
Changing beam heights, adding a level or switching to a heavier pallet changes the rating. SafeWork NSW advises getting the supplier’s approval before altering a configuration, marking the rated capacities where workers can see them, and having a way to check the weight of every unit load going into the racking.
What size is selective pallet racking?
Selective racking is built around your pallets, trucks and building, so there is no fixed size. A common bay holds two standard Australian pallets, 1165 by 1165 mm, side by side on beams of about 2.7 m. Height and aisle width are then set by your forklifts and the building.
| What you are sizing | Typical starting point | What decides it |
|---|---|---|
| Beam length | About 2.7 m for two standard pallets per level | Pallet size and how many pallets sit in each bay |
| Aisle width | 3.0 to 3.5 m for counterbalance forklifts, about 2.7 m for reach trucks, as little as 1.6 m for very narrow aisle trucks | The turning circle of the truck used for picking and replenishing |
| Height | Set by the building | Sprinkler clearance, roof line, forklift mast height and slab capacity |
| Pallet type | Standard Australian pallet | Overseas pallets often differ in size and may not fit Australian racking |
Measure your usable ceiling height, allowing for sprinklers, before specifying any system. A racking supplier who measures your building before quoting will catch problems that a price list will not.
What does AS 4084 require for selective pallet racking?
Steel storage racking in Australia is covered by AS 4084. Part 1, AS 4084.1:2023, covers design, and AS 4084.2:2023 covers operation and maintenance. The standard is not legislation in itself, but SafeWork NSW points to it as the benchmark for keeping racking safe.
The SafeWork NSW pallet racking fact sheet sets out the practical expectations for standard racking:
- Rated capacities marked on the racking and matching the current layout
- Racking fixed to the floor, with at least two anchors in each footplate
- Modifications approved by the manufacturer, supplier or a qualified engineer, and replacement parts sourced from the manufacturer
- Upright protectors and end-of-rack protectors on frames that forklifts can reach
- Rear protection where pedestrians can reach the back of single rows
- A formal inspection by a competent person at intervals not exceeding 12 months
Our pallet racking inspection guide explains what a formal inspection covers and what to do after a forklift strike. The SafeWork NSW fact sheet was adapted from a WorkSafe Victoria guidance note, which is useful if you also operate interstate.
What mistakes should you avoid with selective racking?
Changes made after installation are a common source of risk. The original design assumes a particular pallet, beam layout and floor, and each of those can drift over time.
- Changing pallet type without checking. SafeWork NSW notes that post pallets concentrate load on the beams and may not key in, skid pallets without timber decks can drop through, and pallets that are too small can fall through or too large can overlap the pallet behind.
- Moving beams without updating the sign. A new beam height changes the rated capacity, so the load sign must change with it.
- Ignoring the floor. Older inner-west and south Sydney buildings should have slab condition and capacity assessed by a structural engineer before heavy multi-level racking goes in.
- Leaving aisle ends unprotected. End frames take the most forklift impacts, so upright and end-of-rack protectors belong there first.
- Mixing components from different systems. This is most common with used stock. Beams and uprights from different manufacturers may not connect properly or carry the loads you assume.
When is selective pallet racking the right choice for a Sydney warehouse?
Selective racking is usually the right choice when you stock many product lines in small quantities, pick often and expect your layout to change. If you hold large quantities of the same product, a denser system may suit better. Small items picked by hand are usually better on industrial shelving.
Choose selective racking if:
- You store many SKUs with only a few pallets of each
- You need to reach any pallet at any time, without moving others
- You run standard counterbalance forklifts or reach trucks
- You expect to add bays or change beam levels as the business grows
Look at another system if:
- You hold many pallets of the same product and floor space is your main cost
- Your stock is date-sensitive and moves fast, which pallet flow suits well
- Your loads are long or awkward and do not sit on a pallet
Local conditions matter too. Near Port Botany and Banksmeadow, salt air speeds up corrosion, so ask about galvanised or coated finishes. Selective racking is also widely available second hand, which can lower the cost of a fit-out as long as the components match and are assessed before installation. You can see the options on our used pallet racking page.
Selective pallet racking FAQs
What is the difference between selective and double deep pallet racking?
Selective racking stores pallets one deep, so every pallet can be reached directly. Double deep racking stores them two deep, which adds storage in the same footprint, but the rear pallet cannot be reached until the front one is removed and the system needs a truck with extended reach. Selective suits many product lines, while double deep suits fewer lines with several pallets each.
How much does selective pallet racking cost?
The price depends on the number of bays, the height, the beam ratings, the finish and whether the racking is new or used. Installation and any floor works are separate costs. Ask for a written quote that lists exactly what is included. DRS Racking Solutions offers free on-site quotes across Sydney and NSW.
Does selective pallet racking need to be bolted to the floor?
Yes. The SafeWork NSW fact sheet says floor fixings should be installed and undamaged, with at least two anchors in each footplate. Anchor bolts should also be checked during regular inspections, because loose bolts are one of the things an inspector looks for.
How high can selective pallet racking go?
The system can be designed well above 10 metres, but the building usually sets the limit first. Sprinkler clearance, roof height, forklift mast height and floor slab capacity all come into it, so measure them before specifying a height.
Is selective pallet racking first in, first out?
It does not force any rotation order. Because every pallet is reachable, you can run first in, first out or another method through your procedures or warehouse system.
Summary: choosing selective pallet racking that fits your operation
Selective pallet racking gives every pallet its own position and direct access, in exchange for more floor area per pallet than denser systems. It suits sites with many product lines, frequent picking and layouts that change. Size it around your trucks and building, keep load signs matched to the layout, protect the frames, and book a formal inspection at least every 12 months.
