TRIA recognizes that standardized management systems are an important support in the journey towards continuous improvement and compliance with our customers' requirements and applicable legal requirements.


In our commitment to quality, the environment, and occupational health and safety, we have adopted an Integrated Management System under the compliance of ISO and OHSAS certification standards.


Our certifications include all the activities developed by the company and are certified by TÜV Rheinland, an independent entity and worldwide leader in certification services.


From the beginning, in TRIA Group we have been vigilant in implementing improvement procedures in relation to customers, suppliers, and workers. In 2007, the search for quality in our services and products was recognized with the implementation and certification of a Management System in accordance with the requirements of the quality standard established in the Standard UNE-EN ISO 9001, a certification that has been renewed to the present.


In 2016, TRIA modified the scope of certification based on the UNE EN ISO 9001 standard, including the detail of all the company´s areas of manufacture and capabilities.

For TRIA, the prevention of occupational risks is a priority which helps guaranteeing the safety and health of its workers as well as promoting the improvement of working conditions.


In 2010, TRIA got the certification of its Management System based on the BS OHSAS 18001 benchmark, which allows it to strictly comply with current legislation, perform an adequate control over the risks of its activity, and apply continuous improvement with the main objective of reducing risks for their workers.


Currently the system continues adapted to current legislation but not certified.

UNE 73401

TRIA has adapted its Integrated Management System to the UNE 73401: Quality Assurance in Nuclear Installations.


This adaptation has allowed TRIA to modify the production processes to comply with the nuclear regulation requirements in terms of quality, in order to establish the initial schedules, intermediate and final controls, and product dispatch.
