At Steel Design, quality is not just a goal – it’s the foundation of everything we build. We are proud to announce that we are certified to two key international standards: EN 1090-1 and EN ISO 3834. These certifications demonstrate our commitment to delivering safe, durable, and fully compliant steel structures for clients across Europe.
EN 1090-1 – CE Marking for Structural Components
EN 1090-1:2009+A1:2011 is the European standard that regulates the execution of steel structures and is a legal requirement for CE marking in the construction industry. This certification confirms that our factory production control (FPC) system meets strict EU safety and performance requirements.
EN ISO 3834 – Standard Welding Quality Requirements
We have also implemented EN ISO 3834-3:2021 (PN-EN ISO 3834-3:2021-09), the internationally recognized standard for welding quality management. This standard specifies the standard quality level for fusion welding of metallic materials and ensures that our welded joints are strong, precise, and durable.
Why Our Certifications Matter to You
With these certifications, our customers benefit from:
Guaranteed compliance with EU regulations
Reliable, safe, and long-lasting steel structures
Transparent production processes with full traceability
Confidence that every project meets recognized industry benchmarks
These achievements reflect our ongoing investment in skilled staff, advanced technology, and robust quality systems. They ensure that every steel component we produce meets the highest standards of quality and safety, giving our clients confidence that their projects are built to last.
