SSAB Weathering steel with superb corrosion resistance
SSAB Weathering steel is a corrosion-resistant steel that will minimize total life cycle costs, thanks to its low maintenance needs.
Benefits of using SSAB Weathering steel
High strength structural steel
SSAB Weathering steel is available in yield strength levels from 355–960 MPa, which makes it the perfect corrosion resistant base material for stronger, lighter and more sustainable solutions.
Designing uniqueness into every project
The unique natural look, which changes over time as the surface ages, is created by the oxidation process. SSAB Weathering blends into the environment and combines well with other building materials.
Environmentally friendly
Painted or unpainted, SSAB Weathering steels ensure longer service life at minimum or even no maintenance work. When painted, it can double intervals between maintenance painting compared to other steels, halving maintenance costs.
More about weathering steelsNew weathering steel grades for superior weldability and higher strength
SSAB is now introducing high-strength weathering steel grades 420 ML and 460 ML. When you specify these high-strength grades in bridge construction or to build rolling stock or other structures, you can use less steel yet maintain high strength. Upgrading to these higher-strength steels gives you superior weldability, lower life cycle costs and improved sustainability.

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 continuous composite girder bridge with a reinforced concrete deck consists of 25 steel sections weighing nearly 100 tonnes each.

SSAB Weathering sections
If you’re looking for low-maintenance, corrosion-resistant steel sections with a high sustainability profile, you can rely on SSAB Weathering open sections. A great choice for minimizing total life cycle costs in long-lasting bridges, transport equipment, outdoor art and other structures.
The patina formation process
The speed of change and the final color of the steel are dependent on the atmospheric conditions of a site and the level of pollution – sulfur dense atmospheres will speed up the oxidation process and result in a darker patina. Frequent cycles of wet and dry conditions will also speed up oxidation. The entire oxidation process for this corrosion-resistant steel usually takes between 2–6 years.
Rust – the perfect protection
COR-TEN® for buildings and art
COR-TEN® is a well-known weathering steel brand for buildings and structures, and a favorite facade material among architects and designers. The combination of high-strength, aesthetic appearance, low maintenance and flexibility, make it an ideal choice for projects of all shapes and sizes.
