The base plate is one of the most important components in a pallet racking system. It anchors the upright frames to the floor, providing stability and helping the rack resist tipping or collapse under load. Proper installation, including the correct number of anchors, is essential for compliance with AS 4084:2023 – Steel Storage Racking.
What Are Frame Base Plates?
Frame base plates are steel plates fixed to the bottom of pallet racking uprights. They distribute the load from the upright to the floor and provide a secure point for anchoring bolts.
Key functions include:
Stabilising uprights against tipping or lateral movement
Ensuring proper alignment of the racking system
Supporting the racking structure during normal loading and impact
Anchor Requirements According to Australian Standards
In the past, some racking systems were installed with only one anchor per base plate, which is now considered non-compliant and unsafe. The current standard, AS 4084:2023, specifies:
Each base plate must be anchored to the floor using a minimum of two approved anchors
Anchors must be suitable for the floor type (concrete, reinforced slab, etc.) and rated to resist the expected loads
Proper anchoring is essential to prevent upright rotation, tipping, or displacement
Anchors must comply with the manufacturer’s specifications and Australian Standards for chemical or mechanical anchoring systems
This means simply bolting a single anchor through the base plate is no longer sufficient to ensure stability and compliance.
Common Issues Found During Inspections
Missing anchors: Base plates installed with no anchors or only one anchor
Incorrect anchor type: Using anchors not rated for the floor type or load
Loose or damaged anchors: Over time, anchors can loosen, corrode, or fail
Improper placement: Anchors not correctly aligned with the base plate holes
Any of these issues can compromise the rack’s stability and create a serious safety hazard.
Inspection Guidelines
Verify that each base plate has at least two anchors installed
Check that anchors are the correct type and size according to the manufacturer’s specifications
Inspect for tightness and corrosion; replace any anchors that are loose or damaged
Ensure the base plate is flush with the floor and correctly aligned with the upright
Why Proper Base Plate Anchoring Matters
Base plates keep uprights vertical and stable, especially under load or impact
Two anchors per base plate provide redundancy, reducing the risk of tipping or failure if one anchor is damaged
Compliance with AS 4084 protects warehouse staff, equipment, and inventory, while avoiding potential legal and insurance issues
Final Word
Frame base plates may seem simple, but correct installation is vital for a safe and compliant pallet racking system. Each plate must have two properly rated anchors, fully secured and correctly installed. Regular inspection ensures the rack remains stable, safe, and compliant with AS 4084:2023.
