Coils

To ensure uniform high quality of our products we buy all our starting material from premium steel producers, notably Salzgitter Flachstahl GmbH, our dependable partner of many years.

Our company uses exclusively coils (with a unit weight of up to 50 t) rolled from continuously cast slabs. All process parameters that govern the properties of the steel are controlled and documented by process computers. Comprehensive quality checks both at our and our partners' plants ensure that we get the ideal starting material for our tube production.

The starting material is manufactured to the specified chemical analysis as well as customer and project requirements. Where necessary, our technical customer service provides advice regarding materials selection. Our offering comprises:*
