Strip shape

Thanks to continuous improvements to manufacturing processes, all powercore® grades display a very flat strip shape. However, owing to physical conditions during rolling, thickness variations over strip width can only be reduced to a limited extent.

Attainable strip shape depends on the hot strip shape, the rolling technology, the reduction during cold rolling/final thickness as well as on the forming properties of the material. For this reason, certain requirements can only be met by additional edge trimming.
