Ordering signage for your business but not sure which material to choose? At Safety Signs Australia, we offer four kinds of materials: aluminium, Colorbond, PVC Foamboard and Corflute. While each of our materials has its own benefits and advantages, they also have their own unique applications e.g. aluminium/Colorbond signs are recommended for outdoor use.

All of our signage in HIP/Class1 Reflective carry a 10 year warranty against peeling or fading in outdoor conditions.

While our non-reflective signage with either Aluminium or Colorbond substrates carry a 7 year warranty against peeling or fading in outdoor conditions.

(PVC Foamboard and Corflute carry a 1 year Warranty against fading in outdoor conditions and 5 years warranty against fading in indoor conditions.)

To help make the ordering process simpler, we’ve put together a guide to the features and benefits of our sign materials.

Aluminium Signs

Aluminium is one of the most popular and highly sought after materials we have to offer. This material is ideal for outdoor applications — waterproof, weather-resistant and rust-resistant, aluminium signs can last for decades without cracking or fading in the sun.

Our aluminium signs are 1.6mm thick.

 Pros Cons
  • Strong and durable
  • Weather-resistant
  • Rust-resistant
  • Great for outdoor use
  • Very rigid
  • Slightly pricier than other materials (to match its longevity)


Colorbond signs

Colorbond is a household name in Australia thanks to its roofing and fencing prowess. Colorbond is pre-painted steel with a Zincalume core, making it both strong and lightweight — perfect for outdoor use. The material undergoes strict design, manufacturing and testing procedures to ensure it’s built to last, which is why we offer Colorbond as a signage material.

Our Colorbond signs are 0.55mm thick.

 Pros Cons
  • Durable — will last for years to come
  • Excellent for outdoor use
  • Lightweight material
  • Weather-resistant
  • Rust-resistant
  • Great for building and construction sites
  • More flexible than aluminium



Corflute (from Corex) is the industry name given to corrugated polypropylene, a fluted plastic that’s both lightweight and rigid. The plastic is extruded to have rectangular flutes all the way through it, giving it extra strength. Corflute is popular in the signage industry because it’s cheap, sturdy, and easy to cut to size. 

Our Corflute signs are 5mm thick.

 Pros Cons
  • Cheaper than aluminium and Colorbond Steel
  • Lightweight and durable
  • Medium outdoor longevity
  • Retains ink and colour well in the hot Aussie sun
  • Comes with eyelets for quick mounting and to help prevent tearing.
  • Temporary signage only. Better utilised for special events, construction sites and any other area that requires short-term signage.


PVC Foam Board

PVC Foam Board is a lightweight product that is often used for displays and signage. The material is tough and flexible but is recommended for indoor use — PVC Foam Board signs are only for temporary use outdoors because it has limited weatherability.

Our PVC Foam Board signs are 3mm thick.

 Pros Cons
  • High-impact resistance
  • Lightweight material
  • Printable on both sides
  • Ideal for indoor use
  • Very flexible
  • Not recommended for outdoor use (temporary use only)
