07 Assessment
Advantages
- Non-combustible with superior fire performance (AS1530.1 compliant)
- Excellent strength-to-weight ratio (1/3 weight of steel)
- Outstanding corrosion resistance in marine and coastal environments
- 95% recyclable with minimal energy requirement for recycling
- Easily fabricated using standard tools and techniques
- Suitable for all Australian climate zones and BAL ratings
- Wide range of surface finishes available
- No termite or rot susceptibility
- Consistent dimensional stability across temperature ranges
- Compatible with dissimilar materials when properly isolated
Constraints
- Higher initial cost compared to steel alternatives ($60-150/m)
- Galvanic corrosion potential when in direct contact with steel
- Lower elastic modulus than steel requiring larger sections for deflection control
- Thermal conductivity contributes to thermal bridging
- Softer than steel, susceptible to surface damage during handling
- Welding requires specialised TIG equipment and expertise
- Limited availability in remote regions
- Strength reduction in heat-affected zones after welding
- Fatigue sensitivity under cyclic loading
- Powder coating can chip exposing base material
