The bridge structures are mainly built using high-strength SSAB Domex® steel, especially Domex 460ML grade, which provides a lightweight but very durable structure designed to withstand harsh environmental conditions such as ice, snow, moisture and strong winds.
In total, about 6,300 tons of steel structures were used in the project, with SSAB accounting for more than half of the supplies.
The Kruunuvuori Bridge is about 1,200 meters long, and the central pylon rises 135 meters, making it the longest and tallest bridge in Finland. The bridge is designed primarily for pedestrians, cyclists and public transport, supporting Helsinki's goals of reducing emissions and increasing sustainable urban mobility.
Piles and foundation components were also supplied
In addition to structural steel, SSAB supplied driven and drilled piles for the bridge foundations, totaling approximately 1,050 tons. The piles have diameters of 1220 mm and 1016 mm, while the longest boring piles exceed 40 meters in length and are equipped with specially designed rock shoes.
Steel supports sustainability targets
According to the company, the use of high-strength steel has helped to increase the efficiency of the material and
