Sustainable solutions with SSAB Weathering steel
Galvanizing or painting steel for construction projects increases C02 emissions and costs. SSAB Weathering steel has a natural patina that makes it a more sustainable solution.

Corrosion-resistant steel for a sustainable world
Learn how high-strength SSAB Weathering steel reduces C02 emissions and costs over its entire life cycle.
Use steel better
Manufacturing, transporting, installing and maintaining steel creates C02 emissions. SSAB Weathering steel can reduce total C02 emissions by up to 40%.
No hot-dip galvanizing
More than 120 kg of C02 emissions are released in batch galvanizing a ton of steel. SSAB Weathering steel does not need to be galvanized due to its protective patina.
No or less painting
About 160 kg of C02 emissions are released in painting a ton of steel. SSAB Weathering develops a protective patina over time. And if a structure is painted, it can last twice as long as one in regular steel before you need to repaint.
High-strength steel
SSAB Weathering is a high-strength steel enabling thinner and lighter designs. This reduces the amount of C02 emissions from manufacturing and transportation.
Build smarter
The construction and building industry is responsible for 39% of global C02 emissions. Discover how SSAB Weathering steel reduces emissions while protecting against corrosion.

Stronger and more sustainable products
Sustainable upgrading
Upgrading your existing hot-dip galvanized steel to high-strength SSAB Weathering steel can lead to significant reductions in emissions and costs, while maintaining the same level of durability.
The protective patina
SSAB Weathering steel is protected by a patina layer of rust that is formed during the oxidation process. The patina slows any further oxidation of the steel.
