We work to European standards and ISO certification, with regular audits that safeguard our design, manufacturing, installation and maintenance processes.
Four references that back the way we work.
Quality management
Certification of our quality management system, audited by TÜV Rheinland. It guarantees documented processes, material traceability and continuous improvement in every project we carry out.
Download the 2026 Quality Policy (PDF)Standard governing the conformity assessment of the characteristics of structural steel and aluminium components, a prerequisite for the CE marking of structural steel.
Sets out the technical execution requirements for steel structures: materials, welding, installation, tolerances and quality control throughout fabrication.
Certification corresponding to execution class EXC3, required for structures subject to high loads or environments that are especially demanding in terms of structural safety.
A certification is recognition, issued by an independent body, that a company or product meets a recognised standard. Declaring it is not enough: an external auditor checks it, and checks it again every year.
Documented, controlled processes at every stage, so results are repeatable and do not depend on individuals or on the day.
Steel and aluminium structures sold in Europe need CE marking, and for that the manufacturer must be certified to the EN 1090 standard.
Every material, weld and inspection is recorded, so it is always possible to know what was built, from what, and who verified it.
Regular audits require processes to be reviewed and improved on an ongoing basis.
It is the international standard for quality management systems. It certifies that a company has defined, controlled processes geared to continuous improvement. In our case it is certified by TÜV Rheinland.
It is the declaration that a manufactured structure meets European safety requirements. For steel and aluminium structures it is obtained by manufacturing under the EN 1090 standard, whose part 1 assesses conformity and whose part 2 sets the technical execution requirements.
EN 1090 defines four execution classes, EXC1 to EXC4, according to the consequences of a possible structural failure. EXC3 applies to structures with high safety requirements, such as those under heavy loads or in demanding environments, and calls for stricter welding controls and traceability.
Yes. If you need the certificates to approve us as a supplier or for project documentation, request them through the contact form or at eci@tallereseci.com.
