Why build modular bridges out of stainless steel?

Stainless steel in bridges – Andy Backhouse, Outokumpu


Duplex stainless steel grades are ideal for bridges. Thanks to a combination of strength and corrosion resistance, you can build durable and sustainable structures at a reduced cost. Get an expert introduction to duplex grades.


Case AVA bridge, UK – Noel Lovatt, X-Treme Systems, and Hazel Needham, Expedition Engineering


Meet the pioneering AVA bridge: a prefabricated modular stainless steel footbridge for railway stations. Simple and quick to install, the AVA prototype has potential for adoption across the UK. AVA, a consortium of companies including Network Rail, is revolutionising the way footbridges are built across the rail network, reducing time, cost and carbon in the process.


Benefits of AVA compared to traditional bridge designs

  • 34% lower cost
  • 56% lower CO₂emissions
  • 75% reduction in project time
  • Makes stations more accessible
