07 Assessment

Advantages

  • 100% recyclable with no quality degradation
  • Excellent corrosion resistance (marine environments)
  • Bushfire compliant for all BAL ratings
  • High strength-to-weight ratio
  • Non-combustible (melting point >1400°C)
  • Low maintenance requirements
  • UV stable - no degradation from solar exposure
  • Maintains properties from -200°C to 870°C
  • Available in extensive range of specifications
  • Locally stocked in major Australian cities

Constraints

  • Higher initial cost than galvanised alternatives
  • Lower thermal conductivity than aluminium
  • Requires specialised cutting tools for thicker gauges
  • Can cause galvanic corrosion with dissimilar metals
  • Limited acoustic absorption properties
  • Potential for crevice corrosion in marine environments
  • Grade 304 susceptible to chloride pitting
  • Heavier than polymer alternatives
  • May require earthing for electromagnetic compatibility
