Choosing the right safety sign isn’t just about the message — it’s about the material behind it. The wrong choice can lead to fading, peeling, or non-compliance with Australian Standards. Discount Safety Signs Australia offers a full range of materials so you can match durability, environment, and compliance requirements correctly.
- Safety sign performance depends heavily on the material and environment
- Options include Vinyl, Corflute, Poly, Metal, Aluminium, and ACM panels
- Public road signs require Class 1 Reflective on aluminium
- Short-term, long-term, and permanent use all need different substrates
- Optional protective laminate extends lifespan in harsh conditions
The Materials We Offer include a wide range of substrates designed for different environments and applications.
Vinyl Sticker — A heavy-duty self-adhesive sticker that applies directly to clean, flat surfaces. Best for mounting onto existing equipment, machinery, doors, lockers and walls without drilling or framing. Mounting: Self-adhesive backing — no holes or eyelets required.
Corflute — Lightweight corrugated plastic, perfect for short-term use. Ideal for construction sites, real estate, events and chain-wire fence mounting. Economical and easy to cable-tie. Months of service, not years. Mounting: Standard 4 reinforced eyelets (one per corner). Larger signs add eyelets at approximately 500mm centres along the perimeter.
Poly (Polypropylene) — A 1.5mm UV-stable polypropylene sheet with rounded corners and pre-drilled holes. Best for short-term outdoor and long-term indoor use — more durable than corflute, more affordable than metal. Great for workplaces and warehouses. Mounting: 4 pre-drilled corner holes as standard, ready to fix to walls, posts or fences.
Metal (0.55mm) — Permanent sheet metal with radius corners and four pre-drilled mounting holes. Heavy-duty and weather-resistant — the classic choice for factories, mines, farms and long-term AS 1319 mandatory, warning and danger signs. Mounting: 4 pre-drilled corner holes as standard.
Aluminium (1.6mm) — Premium solid aluminium sheet. Won’t rust, making it the standout choice for coastal and high-humidity sites. More rigid than 0.55mm metal, holds its shape on larger signs, and is the traditional substrate for road and regulatory signage. Mounting: 4 pre-drilled corner holes as standard.
ACM Panel (3mm) — Aluminium Composite Panel: two aluminium skins bonded to a polyethylene core. Extremely rigid, light for its size, and stays beautifully flat on big signs. The premium pick when appearance matters as much as durability. Mounting: 4 pre-drilled corner holes as standard.
Select the right substrate for durability, compliance, and environment—ensuring Australian safety signs perform reliably in all conditions and installations.
Reflective Grades are an essential part of safety signage performance. Class 1 Reflective is a high-intensity grade with a honeycomb pattern and is legally required for any sign installed on a public road in Australia. It is used for street, speed, and roadworks signage, typically applied to a 1.6mm aluminium face.
Class 2 Reflective is engineer grade. It is highly visible but at narrower viewing angles than Class 1. It is ideal for non-regulatory applications such as carparks, depots, yards, and warehouses. Mounting for both grades inherits the substrate configuration, most commonly 4 pre-drilled holes on aluminium.
Always match the material to the environment first, then confirm compliance and reflectivity requirements before placing your order.
Optional Add-On: Protective Laminate is available for high-exposure or high-traffic sites. It is a clear UV-stable protective layer applied over printed sign faces, extending readable life and improving resistance to scratches and abrasion.
Recommended for:
• Direct-sun sites — extends print life under prolonged UV exposure
• High-traffic or vandalism-prone locations — anti-graffiti grades wipe clean of paint and marker
• Coastal and chemical environments — protection against salt, moisture and contaminants
How to Choose is a quick decision framework:
• Lifespan? Days/weeks → Corflute. Short-term outdoor / long-term indoor → Poly. Years outdoors → Metal, Aluminium or ACM.
• Public road? Class 1 Reflective on aluminium — non-negotiable.
• Coastal site? Aluminium or ACM (no rust).
• Mounting to existing equipment? Vinyl Sticker.
• High exposure or vandalism risk? Add protective laminate.
All standard safety sign designs comply with AS 1319 — Safety Signs for the Occupational Environment, and Poly, Metal, Aluminium and ACM signs come with radius corners and pre-drilled mounting holes ready to install.
