Straight answers to the questions we hear most from specifiers, contractors and distributors — no sales pitch, just the standards and reasoning behind them.
EN 1634-1 is the European test standard for fire resistance of door and shutter assemblies.

1. Certification that matches your market.
2. A test report you can read, not just a certificate.
3. Container economics.
4. Hardware compatibility with local codes.
5. Lead time against your program.
The rating isn't a quality tier — it's set by the fire strategy of the building.
As a general pattern, always confirm against your project's fire strategy document.
The safest approach is to never guess: send us the fire strategy drawing.
