Australian warehouses rely on stillages. These storage powerhouses can handle loads of up to 1,400kg, making them indispensable in Australia’s industrial landscape. But what makes stillages so special?
These stackable metal containers come in steel stillages or steel cages. The market now offers pallet cages, collapsible transport cages and stackable stillages to fit different industrial needs while meeting strict safety rules.
This guide will give you the complete rundown of Australian Standards for stillages. You’ll learn everything about compliance requirements and the safety protocols that help prevent accidents.
Updated AS4084-2023 Pallet Racking Standards
There are a number of differences between the 2023 Pallet Racking Standards and the previous 2012 Standards. If you purchased your racking in 2023 or later, you are obliged to abide by the 2023 standard. If your racking was purchased prior to 2023 and has not been moved, you do not need to apply with the latest standard.

Understanding the Regulatory Framework
Australia’s regulatory landscape for stillages follows a detailed framework that ensures workplace safety and better operations. This framework covers standards and regulations that manufacturers and users need to follow.
Key Australian Standards for Stillages
Australian Standard AS 4084-2023 is the foundation for steel storage racking, including stillages. The standard details specific requirements for design, fabrication, erection tolerances, and maintenance procedures. It also provides guidelines for load-bearing capacities and structural integrity tests.
The Occupational Health and Safety Act 2004 requires employers to maintain a safe working environment without health risks. This law applies to stillage use and mandates that employers:
- Provide and maintain safe plant or work systems
- Make arrangements to handle and store materials safely
- Keep workplaces safe and risk-free
SafeWork Australia reports that the structural metal product manufacturing industry’s workers compensation claims are high. As a result, specific stowage rules must apply to stillages, especially those that transport dangerous goods. Class 2 dangerous goods secured in gas industry cylinder pallets need a lashing system that meets Load Restraint Guide requirements. The cylinders cannot extend above 45% of their height over the stillage rail.
Industry specifications state that quality-assured steel stillages should be:
- Made from 100% Australian steel
- Certified to AS4084-2012 standards
- ASSIG (Australian Steel Storage Industry Group) compliant
Transport application stillages must have rigid sides or gates. Items should not stick out horizontally beyond these structures. In spite of that, this rule does not apply to certain containers if they follow load restraint guide requirements.
Safety Requirements for Stillage Design and Construction
Australian safety standards demand precise engineering specifications when designing and building stillages. Worker safety depends on following strict structural and safety requirements to prevent serious injuries from collapsing stillages or falling objects.
Structural Requirements
Strong foundations form the basis of structural integrity. Stillages need proper soleboards and baseplates that evenly spread loads across supporting surfaces, especially when you have unstable ground like soil or gravel. The baseplates must stay level and secure with at least two anchors per footplate to stop movement. Note that no part of the baseplate should protrude over the soleboard to ensure even load distribution.
Load-bearing capacity plays a vital role, as different models come with specific weight limits. For instance, mesh-sided stillages can support 1,500kg, while solid-sided models keep the same capacity but differ in physical specifications based on size.
Manufacturer specifications dictate tie methods and spacing requirements. Chemical anchor installations require testing and proof loading to 125% of the working load. Each insert anchor should maintain a 3:1 safety factor on its failure load.
Australian Standards specify these working platform duty classifications:
- Light Duty: Up to 225kg per platform per bay
- Medium Duty: Up to 450kg per platform per bay
- Heavy Duty: Up to 675kg per platform per bay
Safety Features
Safety features play an equally significant role in stillage design. Workers need protection from falling objects through perimeter containment sheeting or overhead protective structures. Single-row stillage installations need rear protection to stop loads from falling backward.
Upright protectors add another significant safety layer. These components attach to the floor or upright (or both) and resist minor impact loads, particularly in forklift operation areas. The bottom frame portions that might face collisions need upright protectors and end-of-rack protectors.
Required signage must show:
- Manufacturer’s name and installation date
- Working unit load limit for each level
- Total working unit load limit for each bay
- Maximum distances between connecting points
Regular inspection protocols help maintain stillage safety. These checks look for beam deflexion that shows overloading, damaged uprights, loose floor fixings, and missing safety clips or connectors. Businesses should also have emergency procedures ready for possible stillage collapse.
Forklift Compatibility and Operational Guidelines
Selecting and operating the right forklift is critical when handling stillages in industrial settings. The match between forklifts and stillages affects workplace safety and optimises operations in Australian warehouses and construction sites.
Forklift Specifications
Forklifts need specific requirements to handle stillages safely. The fork arms must fit the stillage’s fork pockets, which typically measure 155 x 60mm with standard centre spacings of 850mm. Operators need to verify that their forklift’s load capacity is higher than the combined weight of the stillage and its contents.
Standard stillages require forklifts with a minimum capacity of 1,500kg to handle fully loaded units safely. The lifting capacity should drop by at least 20% when handling bulka bags or flexible intermediate bulk containers. This accounts for dynamic forces from sudden movements.
Fork arm positioning plays a key role: operators must insert the arms fully into the stillage’s fork pockets before lifting. Safety features like mirrors and cameras help monitor the forklift’s surroundings effectively.
Safe Operating Procedures
Drivers must complete pre-start safety checks. These checks include forklift and attachment inspections, control function tests, and seat belt verification. Operators should ask for assistance or drive in reverse safely if their view becomes blocked.
Forklift operators handling stillages must:
- Keep fork arms close to the ground with tips tilted slightly upwards while driving
- Stay under 5-7 km/h in areas with pedestrians
- Keep their body inside the forklift cabin during operation
- Follow traffic management procedures with designated paths and exclusion zones
Proper restraint methods secure stillages during transport. All parts need straps attached to stillages before handling, and the stillages must attach securely to the forklift. Stacking limits apply: empty stillages stack up to four high while loaded ones stack only two high.
Workplaces with multiple vehicles need a complete traffic management plan. This prevents collisions between forklifts and other powered mobile equipment.
Maintenance and Inspection Requirements
Regular stillage maintenance will give a safer workplace and longer equipment life. Australian industrial settings need proper inspection protocols and quick damage assessments to improve operational efficiency.
Regular Inspection Protocols
Staff must conduct visual inspections during all operational stages, from loading to transportation and final use. Australian Standard AS 4084 requires formal inspections “at least once every 12 months”. A trained professional with in-depth knowledge of the Standard and regulations needs to do these inspections to get a full picture of structural integrity and spot potential risks.
A detailed inspection should look at:
- Horizontal (base) members for bending or distortion
- Vertical posts for structural integrity
- Weld points for cracks or failures
- Foot plates for damage, distortion or collapse
- Signs of deep rust, corrosion or concrete build-up
Detailed inspection reports that highlight needed repairs are vital. These documents help with “ongoing reporting and safety maintenance” and prove compliance with regulatory requirements.
Damage Assessment and Repair
The severity of damage determines a stillage’s classification. You should remove equipment from service right away if you find:
- Bent or collapsed frame members
- Cracked welds at critical junctions
- Foot plates with damage, distortion or signs of tearing
- Missing components that affect structural integrity
Staff should “assess and if deemed to be unsafe, remove from circulation” any damaged stillages. Only qualified personnel should handle repairs using manufacturer-approved components. Never mix components from different scaffold systems as this makes the structure unsafe.
The repair process requires that “damaged stillages are to be returned to the manufacturer for proper assessment or repair.” The manufacturer, supplier, or a qualified engineer with specific equipment knowledge must approve any modifications.
Keeping accurate repair and replacement records helps track each stillage’s service history and maintains compliance with Australian Standards.
Industry Best Practices and Case Studies
Australian workplaces need to implement stillage standards as a practical necessity, not just to meet regulations. Studies from manufacturing sites show most important improvements in operational efficiency and worker safety through proper stillage management.
Implementation Examples
The best way to implement these standards starts with a full picture and team involvement. To give an example, a structural metal product manufacturing facility’s management reduced incidents by 20% after developing a systematic maintenance program. This program clearly defined how often stillages needed maintenance and what needed to be done. The site took a proactive approach:
- Daily visual inspections checked for damage and overloading
- Quarterly assessments looked at structural components
- Qualified engineers conducted complete evaluations yearly
Many facilities go beyond the basics with innovative safety measures. To name just one example, they install racking with beams at knee height in bottom bays. This reduces damage from pallets hitting uprights during forklift operations. The modification also helps workers pick items more easily by raising them to better heights.
Common Compliance Challenges
Companies know the regulatory requirements but struggle to apply them consistently. Safe Work Australia’s research shows employers believe they’ve “done all they could to minimise risk.” However, they rarely look for new ways to improve safety.
The biggest problem lies with proper inspection protocols. Inspections should happen “frequently based on manufacturer recommendations.” Yet many facilities don’t have proper systems to track these evaluations. This creates problems with accountability when incidents occur.
Without doubt, keeping appropriate clearances creates another challenge. Unit loads that contact uprights or beams cause much damage. Stillages need enough space to prevent loads from pushing against nearby racking.
Success comes from a culture committed to safety rather than just checking boxes. The best facilities have supervisors with specific stillage safety training who know how to communicate requirements effectively to their team members.
