07 Assessment
Advantages
- Non-combustible - suitable for all BAL ratings
- High strength-to-weight ratio
- Excellent durability and weather resistance
- 90% recyclability rate in Australia
- Customisable patterns and open areas
- Allows controlled light and air passage
- Low maintenance requirements
- Magnetic properties aid recycling
- Local manufacturing availability
- Wide range of finishes available
- Vandal resistant
- Termite proof
Constraints
- Thermal conductivity requires insulation backing
- Corrosion risk without protective coating
- Limited acoustic absorption without backing
- Weight increases with thickness
- Cut edges require edge protection
- Pattern visibility can limit privacy
- Strength reduction with higher open areas
- Potential for galvanic corrosion with dissimilar metals
- Higher cost than solid sheet for same thickness
