COR-TEN® A for façades
Download data sheet
Typical COR-TEN® A weathering steel thicknesses for application in façades are 1.0 – 1.5 mm. However, COR-TEN® A weathering steel in cold rolled delivery condition is available in thicknesses ranging from 0.7 – 3.0 mm and widths from 30.0 - 1530 mm as slit coil / coil. Cut to length sheet are available in widths ranging from 1000 – 1530 mm and lengths from 900 mm – 8500 mm. For any further information on dimensions available or special requests, please contact SSAB’s Tech Support.
COR-TEN® A weathering steel in cold rolled delivery condition looks like any other cold rolled steel. Typically, it comes with a thin layer of protective oil. As soon as this protective oil is removed, and the steel is exposed to alternating wet & dry atmospheric conditions, the patina layer will start to form.

Tensile testing is carried out transverse to the rolling.
If the yield point is not pronounced, the values apply to the 0.2% proof strength Rp0.2. If the yield point is pronounced, the values apply to the lower yield point (ReL).
COR-TEN® A in cold rolled condition is supplied with thickness and width tolerances in accordance to EN 10131. More narrow thickness tolerances are available on request.
Cut to length are supplied with length tolerances in accordance to EN 10131.
Cold rolled dry or cold rolled protection oiled. We recommend protection oiled delivery condition.
Protective oil protects the surface from moisture and prevents the patina formation too early or unevenly. However, when delivered as oiled, the oil as well as other impurities must be removed from surfaces when steel sheets are installed. When delivered as dry, there is a risk that patina starts to create unevenly leading to irregular appearance in the end application.
The COR-TEN® A steel can be cold formed in the same manner as general structural steels of the same strength.
