Frequently asked
Why is a 'Do Not Block' sign important for fire doors?
Fire doors must close automatically to contain smoke and flames; blocking them—even temporarily—compromises life safety and violates building codes.
Which material is best for high-traffic areas?
Vinyl or Colorbond steel are most durable in busy environments where signs may experience wear, impact, or frequent cleaning.
Do you supply these signs ready to install?
Yes; we offer pre-drilled holes and optional lamination, so signs are ready to mount immediately upon arrival.
Are these signs compliant with Australian fire safety standards?
The appropriate safety-sign category, wording, placement and supporting controls depend on the product purpose, site risk and applicable jurisdiction. Confirm the requirement with your WHS adviser or regulator; a sign alone does not discharge WHS duties.
Can I order in bulk for a multi-site roll-out?
Automatic volume pricing is 5–9 signs: 8% off, 10–24 signs: 15% off, 25–49 signs: 24% off, 50–99 signs: 32% off, 100+ signs: 40% off. The configurator is the source of truth and updates the unit price as quantity changes.
