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. |  |
| 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. Photo: Edge profile of Aluminium (1.6mm) |
| 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. Photo: Edge profile of Poly (Polypropylene) |  |
| 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. Photo: Edge profile of Vinyl Sticker |
| 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: Standard 4 reinforced eyelets (one per corner). Larger signs add eyelets at approximately 500mm centres along the perimeter. |  |
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. | |
 | Mounting: Inherits the mounting configuration of the substrate — most commonly 4 pre-drilled holes on aluminium. |
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. | |
| Mounting: Inherits the mounting configuration of the substrate (typically 4 pre-drilled holes). |  |
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.
