SSAB Weathering steel defies marine conditions on the Huikku Bridge in Hailuoto
SSAB Weathering 460ML steel is the main material used in the Huikku Bridge, which is part of a causeway connecting Riutunkari, Oulu, and Huikku in Hailuoto, which is the largest island in the Bothnian Bay. The 767-meter-long cntinuous composite girder bridge with a reinforced concrete deck consists of 25 steel sections weighing nearly 100 tonnes each.
“They are impressive structures, not just matchsticks,” laughs Henrik Kiviniemi, Business Director at Steel Group Pohjanmaa Oy, the company which is responsible for the engineering of the bridge steel structures.
