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.
X-Treme Systems were replaced as bridge fabricators in 2023 within the AVA consortium with a new fabricator, McNealy Brown Ltd.
For more details about AVA bridge and consortium members see www.avabridge.com.
Benefits of AVA compared to traditional bridge designs
- 34% lower cost
- 56% lower CO₂emissions
- 75% reduction in project time
- Makes stations more accessible
