Description
This AS 1319 danger sign warns unauthorised persons to keep out of construction sites, meeting Work Health and Safety Act compliance across Australia. The large-format aluminium construction suits permanent site boundaries, main entrances, and high-visibility zones where the message must carry authority and durability. Aluminium is engineered to resist corrosion, UV fading, and physical damage from weather, vehicles, and handling on active sites. Three larger sizes (600×450 to 900×1200 mm) ensure visibility from significant distances — essential for busy urban sites or multi-level developments. Reflective Class 1 and Class 2 options enhance night-time visibility; lamination protects against scratches and graffiti. Platinum Signs supplies contractors, builders, and site managers Australia-wide with trade pricing and bulk discounts. We deliver within 5–7 working days and can arrange custom wording or branding on request.
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
Why aluminium instead of other materials?
Aluminium resists corrosion, UV fading, and dents from site activity. It's ideal for permanent or long-term installations where durability and professional appearance matter.
What size is best for a main site entrance?
Available sizes are 600 x 450mm, 900 x 600mm, 900 x 1200mm. Viewing-distance notes are a practical selection aid, not a substitute for checking the approach distance, lighting, mounting position, wording and site risk assessment.
Should I choose Class 1 or 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.
Can you add my company branding or site details?
Yes — we customise signage with contractor name, site address, emergency contact, or company logo. Request a quote with your specifications.
Do you offer volume pricing for multiple sites?
Yes — builders and large contractors benefit from trade pricing on bulk orders. Set up a trade account and we'll provide tailored rates based on your volume.
