Description
Keep building security and climate control consistent with this AS 1319–compliant notice sign. The blue-header format signals a procedural requirement rather than a hazard, making it ideal for fire safety, HVAC management, and access control across offices, warehouses, and retail spaces. Offered in corflute, polypropylene, Colorbond, and vinyl in sizes from 225×300 mm to 600×900 mm. Enhance durability with lamination or add reflective finish (Class 1 or 2) for stairwells and emergency routes. Pre-drilled mounting holes included. Manufactured in-house using fade-resistant inks on premium Australian materials. Trade customers benefit from volume discounts and nationwide delivery within 5–7 business days.
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
Is this sign suitable for fire-rated doors?
Yes, it reinforces the procedural requirement to keep fire doors closed. Pair it with your building's fire safety signage to support compliance audits.
What's the difference between Class 1 and Class 2 reflective finishes?
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.
Can I laminate after purchase, or should I order it pre-laminated?
We apply lamination during manufacture for best results. Pre-laminated signs have superior edge protection and finish consistency.
What's the lead time for custom text variations?
Standard stock items ship within 5–7 days. Custom text or artwork requires 10–14 days; contact our trade team for urgent turnarounds.
Do you supply signage for multi-building contracts?
Yes. Trade accounts can consolidate orders across multiple sites and receive tiered pricing. We manage delivery scheduling to suit your project timeline.
