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.

GP PRODUCT FINDER – THE EASY WAY TO FIND YOUR PERFECT ROLL

The GP product portfolio comprises of a wide range of work and back-up rolls for steel rolling mills. Our roll configurator helps you find the perfect rolls for your requirements. If you are interested in our grooved rolls or rolls for aluminum rolling mills, please contact our sales department directly.

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.

Select

Cold 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.
