The first weathering steel bridge in the UK was a footbridge at York University in 1967 and the material was used for many bridges around the UK in the following 30 years or so.However,the use of weathering steel on bridges has increased significantly since 2001 when a former restriction on the use of the material over highways with less than results for this questionWhat are the standards for weathering steel?What are the standards for weathering steel?Comparison of the material standards for weathering steel (EN 10025-5 ) and ordinary structural steel (EN 10025-2 ) shows that the specification requirements for all other elements in the steel chemistry are similar.Weathering steel - SteelConstructionfo results for this questionWhat is the lifespan of a weathering steel bridge?What is the lifespan of a weathering steel bridge?The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance.Hence,a well-detailed weathering steel bridge in an appropriate environment provides an attractive,very low maintenance,economic solution.Weathering steel - SteelConstructionfo
