SSAB has announced the completion of the world’s first bridge built with SSAB Zero™ steel, marking a notable application of low-carbon steel in infrastructure projects.
The bridge spans 39 meters, weighs more than 30 tonnes, and is located over the E22 highway in Lund, Sweden. The project forms part of a wider infrastructure upgrade led by the Swedish Transport Administration.
Approximately 95% of the steel used in the bridge is SSAB Zero™, which is produced from recycled steel using fossil-free electricity and biogas. According to SSAB, the steel has a production carbon footprint of less than 0.05 kg CO2e per kilogram of steel within Scope 1 and 2 emissions under the GHG Protocol.
The use of SSAB Zero™ resulted in a 70% reduction in carbon emissions compared with a bridge built using conventional steel, equivalent to approximately 46 tonnes of CO2 emissions avoided.
SSAB said the project demonstrates how low-carbon steel can be integrated into large-scale infrastructure projects through collaboration across the supply chain. The bridge was manufactured by Hjalmarssons in Sölvesborg, which reported that the material could be processed using existing manufacturing methods without requiring significant adjustments.
Why it matters for green steel: The project demonstrates the growing use of low-carbon steel in infrastructure applications. As governments and developers seek to reduce emissions from construction projects, large-scale deployments help validate the commercial viability of decarbonized steel products. The bridge also highlights the role of recycled materials and fossil-free energy in reducing the carbon footprint of steel production while supporting broader climate goals.
