Quality under control

At TOS, quality is central to every project. We work with carefully selected production partners who adhere to strict European quality standards. Every product is inspected for dimensions, material, and finish to ensure it fully meets our customers’ specifications. If required, measurement reports, material certificates, and laboratory tests can be provided upon delivery. We also collaborate with SGS and other independent testing and inspection organizations for additional quality assurance. This allows TOS to offer complete transparency, reliability, and certainty—from prototype to series production.

How does TOS keep quality under control?

Our quality control goes beyond simply inspecting and reporting. Within TOS’s international network, we work exclusively with production partners who hold recognized certifications, including ISO 9001 (quality management), ISO 3834 (quality requirements for fusion welding of metals), EN 1090 (CE marking for steel and aluminum structures), and IATF 16949 (automotive quality management).

To ensure quality and traceability, we conduct rigorous checks in collaboration with SGS and other independent laboratories and inspection agencies. Depending on the project’s requirements, measurement reports, material certificates, and laboratory reports can be prepared and included with delivery. This way, you know exactly what you’re receiving – including demonstrable quality and the provenance of each component.

At TOS, we believe that quality isn’t a coincidence, but the result of knowledge, structure, and collaboration with reliable partners. By combining technical expertise with independent quality control, we guarantee products that meet the strictest European standards and exceed our customers’ expectations.
