KRAIBURG Relastec, as part of the KRAIBURG Holding, specialises in sub-ballast mats and bearings for mass-spring systems with its DAMTEC® division. KRAIBURG Relastec has already established itself through numerous international projects with its DAMTEC® products and offers its partners an extensive range of solutions to reduce noise and vibration problems in rail traffic.

DAMTEC® products have been tested in recognized external testing institutes and internally for the sometimes very demanding, project-specific conditions and specifications. It goes without saying that KRAIBURG Relastec is ISO 9001 certified and thus guarantees consistently high quality and complete traceability of its products.

Manufacturer-related product qualification (HPQ) and Q1 certification at Deutsche Bahn AG

KRAIBURG Relastec has been awarded the „Manufacturer-related Product Qualification (HPQ)“ by Deutsche Bahn AG and the „Supplier`s Quality Capability“ is classified as Q1 for the product range of sub-ballast mats by Deutsche Bahn AG (DB AG).

The HPQ qualifies a manufacturer to produce a particular product using specific processes already described in standards, drawings or other technical documentation. It is required every three years for the annual Q1 certification.

The Q1 certification is the classification of a company, which is audited within the scope of DB AG‘s supplier management with regard to quality capability. As a Q1-supplier of DB AG, one is authorised by the client DB AG to supervise prefabrication services on one‘s own responsibility. Project-related external production approvals are no longer mandatory.

Our sub-ballast mats comply with the technical delivery conditions and are approved for use in the DB AG network (according to DBTL 918071 and e. g. TM-2015-10511 LNPF 1).
