Calculate the corrosion loss

How much corrosion can Weathering steel resist? All steels oxidize after some time, but some more than others. When choosing the thickness of the steel, you should take corrosion levels into account.

Calculate expected rate of corrosion

What is the expected level of corrosion?

Select corrosion category.

Enter the number of years you want to calculate for.


Fill in the data and the calculated rate of corrosion will be shown here.

Calculating on over years would result in an expected corrosion loss of:

If you choose to use weathering steel without painting it, you will save dioxide emissions. If painting, you still have reduced CO2 emissions because you would not have to repaint the steel as often as with a regular carbon steel.

SSAB Weathering for structures and bridges

Structures and bridges

SSAB Weathering is the ideal choice for steel constructions that are difficult to reach and expensive to maintain.
SSAB Weathering for heavy transport

Heavy transport

Heavy transports in SSAB Weathering steel are strong, hardwearing, take higher payloads and are relatively light compared to vehicles made from conventional steel.
SSAB Weathering steel for process industries

Process Industries

SSAB Weathering steels is resistant to high temperatures and a sulfur-rich atmosphere, common in petrochemical plants.
