Precision in a wide range of products
Cold rolling
The specifications of cold rolled precision strip should be based on your requirements, not on your supplier's plant technology.
In the Giebel cold rolling plant we can produce cold rolled strip in thicknesses from 0.075 mm and widths up to 1,060 mm thanks to two ultra-modern rolling mills and the know-how gained from over 80 years of high-tech forming.
Our product portfolio includes a wide range of steel grades from structural steel to micro-alloyed special raw materials. The surface types MA, MB and MC are available, in various defined degrees of roughness and with variable peak values based on the respective specifications.
High productivity
For us, cold-rolled steel strip is not just a work piece, rather it is a part of a tightly synchronised production and supply chain characterised by efficiency and cost effectiveness over several stages of production. With intelligent solutions such as our oscillated wound coils, we are contributing to a higher degree of productivity in further processing. Easy handling and short set-up times are possible even with long strip lengths thanks to the compact dimensions of the pack winding.
Cold Rolled Strip
Our steel portfolio includes cold rolled strips in a variety of grades, dimensions and surface finishes. Whichever of our products you choose, both production steps take place in succession at Knauf Interfer Cold Rolling GmbH in Iserlohn.
The best material properties can only be achieved by keeping an eye on the entire production process. We place great importance on maximum precision and the lowest tolerances. Precisely coordinated pre-material specifications are an essential prerequisite for an optimal cold-rolled product, for example precision strip steel. The synthesis of technology and tools is a result of years of experience and development as well as sustainable quality assurance.
