Welding engineer: Pavel Kopanev (IWE — International Welding Engineer)
ISO 3834-2 is the European standard for welding quality requirements. Level “2” means full quality compliance — the same level required for high-responsibility structures such as bridges, industrial buildings, and energy facilities. Our welding supervision is provided by an IWE-qualified engineer (the highest international welding engineer qualification).
EN 1090-2 EXC 3 — Steel Structure Manufacturing (ISM OÜ)
Standard: EN 1090-2:2018+A1:2024
Execution Class: Up to EXC 3
Holder: ISM OÜ (our production company)
Issuer: TÜV Eesti OÜ (Notified Body 1526)
Certificate No.: 1526-CPR-1090-1.0122.TÜVEESTI.2025.000
Valid until: 27.10.2028
EN 1090-2 is the European harmonized standard for steel structure design, manufacturing, and installation. EXC 3 is the higher tier of the four execution classes — covering structures whose failure could have serious consequences: major bridges, large industrial buildings, high-rises, energy facilities, and critical infrastructure. Our EXC 3 certificate allows us to take on projects where EXC 2 is not sufficient — a key advantage for tenders on large industrial and infrastructure projects.
