Roofing fasteners work for years under load, in moisture and changing temperatures. A single failed fastener costs incomparably more than the fastener itself. That is why every product we ship has a documented path — from incoming material to finished goods.
Management systems
We operate two certified systems:
- ISO 9001 — quality management
- ISO 14001 — environmental management
Factory production control
Our fasteners are covered by factory production control, confirmed by certificates of conformity issued for the European Technical Assessments ETA-18/0789 and ETA-19/0586. In practice this means our production process is assessed by an external body — we do not rely on our own declaration alone.
European Technical Assessment
For assessed fasteners we hold ETA-18/0789 and ETA-19/0586 — documents issued under the European procedure, describing performance verified by testing. On that basis we issue Declarations of Performance (DoP) and national declarations.
What this means for you
- Every delivery comes with a complete set of documents for project handover records
- Load capacity and corrosion resistance are backed by documents, not just a catalogue sheet
The full set of documents is available under Files to download.
