Description
Stack Correctly signs communicate safe storage practices to prevent injuries from unstable loads or collapsed stacks. Compliant with AS 1319, the yellow and black triangle design ensures immediate recognition in warehouses, storage areas, and distribution centres. Choose from corflute, polypropylene, Colorbond, or vinyl across 225×300 mm, 300×450 mm, 450×600 mm, and 600×900 mm formats. UV-resistant inks maintain clarity in direct sunlight. Add reflective Class 1 or Class 2 finishes for visibility in dim conditions. Platinum Signs supports trade buyers with volume pricing and nationwide delivery.
Final sign type, wording, size, placement and material depend on the site risk, project specification and applicable jurisdiction. Confirm the requirement with the relevant WHS adviser or regulator.

Frequently asked
Which size works best for warehouse aisles?
450×600 mm is the standard for warehouse aisles where operators need clear sightlines from a distance. For narrower aisles or racking areas, 300×450 mm is often sufficient.
Is lamination worth the extra cost?
In high-traffic warehouses with forklifts and machinery, lamination protects against scuffs and extends sign life by 2–3 years. For static storage areas, it's less critical.
Can I customise the message or add our company logo?
Our standard range uses AS 1319 approved text and symbols. Custom designs are available on request—contact sales to discuss your specific requirements and lead times.
What's the difference between Class 1 and Class 2 reflective?
Reflective grades provide different visibility performance. Choose the grade required by the project specification and site conditions, and confirm any road, traffic or high-risk requirement with the relevant authority before ordering.
Do you supply fixings or mounting hardware?
We drill mounting holes at no extra charge. For fixings, we recommend sourcing stainless steel bolts or self-adhesive strips locally, depending on your surface type.
