SSAB supplies high-strength steel for Kruunuvuori Bridge in Helsinki
Swedish specialty steel manufacturer SSAB has announced the delivery of over 3,000 tons of high-strength structural steel for the Kruunuvuori Bridge in Helsinki, one of the largest bridge projects ever undertaken in Finland.
The bridge structures are mainly made of high-strength SSAB Domex® steel, in particular Domex 460ML grade steel, which provides a lightweight but very durable structure capable of withstanding harsh environmental conditions such as ice, snow, humidity and strong winds.
In total, about 6,300 tons of steel structures were used in the project, with more than half of the shipments coming from SSAB.
The Kruunuvuori Bridge is about 1,200 meters long, and the central pillar rises to 135 meters, making it the longest and tallest bridge in Finland. The bridge is designed primarily for pedestrians, cyclists and public transport, contributing to Helsinki's goals of reducing emissions and increasing sustainable urban mobility.
Piles and foundation components are also supplied.
In addition to the metal structures, SSAB supplied driven and drilled piles for the bridge foundation with a total weight of about 1,050 tons. The piles have a diameter of 1220 mm and 1016 mm, and the longest boring piles exceed 40 meters in length and are equipped with specially designed shoes.
Steel pillars for achieving sustainable development goals
According to the company, the use of high-strength steel has contributed to increased material efficiency and reduced environmental impact due to lighter structures and longer service life.
SSAB said that carbon dioxide emissions from its steel are about 6% lower than the European average and 17% lower than the Chinese average, confirming that the project's climate targets have been achieved.
