In the fall of 2020, our norwegian customer, Sverdrup Steel, got a commission from Equinor to build footbridges to replace the existing carbon steel footbridges with Lean Duplex as a more sustainable and durable solution.

Lean Duplex hollow sections to footbridges – Sverdrup Steel

Sverdrup Steel wanted to challenge the existing solution and replace carbon steel with Lean Duplex as a more sustainable and durable solution. With the use of Lean Duplex it is possible to have a lighter structure, less maintenance, and reduce the CO2 footprint.

With good assistance from Sverdrup Steel’s technical team of metallurgists and the availability of material, the change from carbon steel to Lean Duplex was a fact. The selected material grade was Lean Duplex acc. to EN 1.4362 / UNS S32304 in accordance to NORSOK M:120 – MDS YD37. They supplied over 2000 meters of structural hollow sections in addition to plates and hot rolled angle bars.

Structural hollow sections manufactured by Stalatube.
