Rolls
Gontermann-Peipers is a well-known name in the international steel and aluminum industries. GP is synonymous with a wide range of wear-resistant and high-performance rolls of excellent durability, manufactured with the highest precision.
Particular highlights of GP’s product range include work rolls in HSS and semi-HSS grades and double-poured back-up rolls with final weights of more than 200 metric tons.
In addition to the manufacturing of rolls, we also offer complete after-market and consulting services, covering all aspects of the roll and its actual application in the mill. These activities are accompanied by continuous Research & Development on new roll materials, which we test and optimize in close cooperation with our customers at their facilities.
Rolls | FORMING TECHNOLOGY
The forming process in a rolling mill is a crucial stage in the manufacturing chain of flat products, such as plate, sheet or strip. Whether for products used in shipbuilding, civil engineering and pipeline construction, or for airplane and automotive body sheets – Gontermann-Peipers rolls shape the world!
To meet the specific requirements of every application, a wide range of rolls and rolling mill types is needed. Therefore, GP's product portfolio includes virtually all types of rolls used in the steel and aluminum industries worldwide.
Whether work rolls for creating the highest surface quality, or backup rolls to support the mill’s maximum roll forces - Gontermann-Peipers supplies the technology ensuring optimal interaction between tooling and process to achieve the best possible final product for our customers.

Please select between hot rolling mill and cold rolling mill:
Hot rolling mill
In the hot rolling mill, the rolling stock undergoes its first forming stage. Hot slabs, blooms or billets are reduced and formed by rolling – via three different process routes – into plate, hot strip or sections.
SelectCold rolling mill
Part of the products from the upstream hot rolling process undergo a second forming stage in the cold rolling mill. For cold rolling, the rolling stock does not have to be reheated. Compared to hot rolling, the cold rolling process achieves smaller dimensions, higher dimensional accuracies, higher strengths and superior surface quality.
