Zylinder | Material use and procurement

To meet the demanding level of our customers, we use nothing but raw material from quality suppliers.

Just as carefully and as a matter of course we track the material batches from receipt of goods through production to dispatch.

We purchase tubes made of fine structural steel grades S355 to S890 almost exclusively from Vallourec-Mannesmann and Ovako. An impact test in longitudinal and transverse direction at -27° C and -40° C respectively ensures the function of the cylinder even at extreme temperatures.


Thanks to the long-standing partnerships with our suppliers, we are able to procure prefabricated steel tubes that meet the exact requirements of our customers.

This ensures our high quality standard – at the same time this is the basis for cost-optimized production with cost-effective solutions for our customers.


We select the sealing system with our system partners depending on the thermal or mechanical environment, matched to the hydraulic medium.

The purchasing of materials and services lays the foundation for the successful realization of projects.


With a good instinct, sound knowledge of the industry and perseverance, we find the products and services for our clients with the optimal ratio of quality and price. Long-standing business relationships with industry-leading suppliers guarantee absolute adherence to delivery dates.
