Quality management


Superior Quality Management (MCS)

Quality and customer satisfaction are our number one priority. Therefore, all the processes in our organization are defined by our internal quality management system.

As a supplier of:

  • stiffened elastomeric supports
  • deformation supports
  • container bearings
  • Spherical bearings
  • limiting structures and targeting supports

We offer our customers to become part of our quality management system and we allow them to meet the quality management system’s quality criteria.

In addition to the internal quality control procedures implemented, our supporters go through regular quality reviews and documentation to independent external organizations.

This includes:

  • Monitoring of reinforced elastomeric supports

Elastomeric supports manufactured according to EN 1337-3 bear an external control according to DIN 18200. Supervision is done by the MPA (Institute for Material Testing) NRW Dortmund

  • Monitoring Support Structures

External controls for all support structures (deformation bearings, spherical ball bearing bearings and containment structures) are carried out by the MPA Stuttgart. These checks are carried out every three months as factory production control.

  • Verification of compliance according to DIN 18800-7

Limiting structures are steel parts that support a load. We therefore have the certificate for welding of steel constructions according to 18800-7. Our skilled welders are trained and supervised by SLV Duisburg (One of the top 10 Welding Engineering Education and Training Institutions in Germany and one of the most important welding institutions in the whole of Europe).

Quality control supports are construction products tested in accordance with German federal building regulations. In order to ensure that the requirements are fully met, the regulations stipulate continuous production control. The results of personal quality control must be documented and analyzed.

The internal quality control system is based on the requirements of these rules and regulations. Our system is regularly reviewed and optimized.
