Sandvik stainless steel in tunnel construction

NSB AS, the Norwegian state-owned railroad company, started building a high-speed railway, creating a triangle from Oslo to southern Norway and then up to Bergen, navigating the scenic attractions, all of which required a great deal of innovative thinking as well as experienced partners. The construction company Hollandia was commissioned to provide the ceiling construction inside the Holmestrand station.

To ensure safe construction, construction company Hollandia looked for a corrosion-resistant material with high strength. The solution was a ceiling suspended from the rock in adjustable hangers made of duplex hollow bar. “Duplex stainless steel is unbeatable if you want a corrosion-resistant material with excellent mechanical properties. Maintenance-free Sanmac™ 2205, with its long life and low weight, was a perfect match for Hollandia,â€? says Christer Thorsson, Global Product Manager for hollow bar at Sandvik. Thorsson means that the Holmestrand project is a great reference for Sandvik.
