The TENAX Quality Assurance System


An ISO 9001 certified business system

Quality has always been a strategic objective for TENAX in order to ensure maximum customer satisfaction and to implement this the company obtained the ISO 9002 certification at the beginning of the 1990's.

Then, the TENAX Quality Management System has been assessed and certified in accordance with the ISO 9001:2008 Quality Standards by SGS Italy and SGS UK. It has been extended to the TENAX Group and to the Chinese Subsidiary TENAX Tianjin.

The scope of registration covers design, manufacturing and sales under the TENAX trademark of extruded polymeric nets, geogrids, geocomposites, three-dimensional structures and related products. The system is constantly updated and implemented using specific procedures targetted at on-going improvements in service and product quality.

In 2002 TENAX also obtained the approval for CE marking on products to be used for construction applications. This approval has been issued by the tBU German European Notified Body.

Other certificates

Following exacting appraisal, the TENAX Geosynthetics products have been awarded important endorsement certificates from major international organizations for use in reinforced soil structures having design life greater than one hundred years.
