SSAB Weathering is a corrosion-resistant steel that saves costs from day one. This makes it an ideal building material for bridges and other structures that need to be corrosion resistant.
Calculate your CO2 savings Contact usTo cope with the elements and the constant strains put on bridges, structural materials have to be extremely strong and durable.
SSAB Weathering steels are available in yield strength levels from 355–960 MPa. This allows for sophisticated design of lighter and stronger structures, easier to erect and reducing transportation movements.
Regardless of the decision for a painted or unpainted bridge structure, SSAB Weathering steel offers either less maintenance repainting or minimal maintenance altogether.
Don't miss out on SSAB’s comprehensive steel solution for bridges. SSAB offers steel products both for superstructure (girders, trapezoidal profiles) and substructure (LSAW tubes, piles for foundation).

The oxide layer that transforms into patina behaves as if it was a paint coating. It seals-off the steel surface from the atmosphere and prevents corrosion. This allows for applications in non-painted condition, leading to considerable maintenance cost savings. The oxide-to-patina process takes place under normal atmospheric conditions, with rainy, snowy and sunny days. No anti-corrosion treatment is needed, which lowers overall costs.
SSAB Weathering steel has a much smaller environmental footprint than non-weathering steels. Emissions and pollution to the structure’s surrounding, caused by painting and stripping before re-painting, can be avoided when used in unpainted condition. A steel bridge made of SSAB Weathering steel is 100% recyclable at the end of its service life. This is a key selling point for many large scale infrastructure projects today.
The appearance of a structure is an important consideration for any infrastructure project, particularly large-scale structures such as bridges or towers. The patina of SSAB Weathering steel is renowned for the way it blends in with its surroundings, particularly in the countryside. For example, a weathering steel bridge made from SSAB Weathering steel can provide a softening tone when used in conjunction with concrete or other structural materials that can be overbearing on their own.
Back in 1889, construction was completed on one of the world’s most iconic structures – the Eiffel Tower. At a total height of 324 meters and a weight of 7,300 tons, it was an architectural and engineering masterpiece. Gustave Eiffel’s material of choice was wrought steel. But what would have happened if the Eiffel Tower had been made of SSAB Weathering steel?
Well, if they hadn’t painted it, they would have saved 8.6 tons of paint a year and all the man-hours that it entails. That is a staggering 1,092 tons of paint, which is shocking when you consider that rust would work just as well with a similar look.
The award-winning pedestrian bridge near Lake Kuusijärvi in Finland not only resists corrosion, requires little maintenance and is visually striking. Thanks to SSAB Weathering steel, it also helps to reduce lifecycle costs and carbon footprint.
Painted SSAB Weathering steel was subjected to a six-year test, where it was exposed to corrosive salt air and extreme weather conditions.
Learn about SSAB’s portfolio of weathering steels for the construction of low-maintenance bridges that deliver superior corrosion resistance and help you reduce life-cycle and environmental costs. Sami Niemelä from design firm WSP will also be showcasing his award-winning bridge in the forests of Finland.
The Hashalom railway station in Tel Aviv, Israel, is the country’s busiest railway station, and features an unforgettable design – a flying carpet-like roof of steel and glass. For its construction, renowned architect Eri Goshen chose to use COR-TEN® weathering steel from SSAB in combination with a paint coating.
The webinar will address topics, such as: How SSAB Weathering steel forms its protective patina layer during the oxidation process. How effective painted SSAB Weathering steel is in resisting degradation and retaining paint within a corrosive environment. Real-world applications of SSAB Weathering steel.
