Not every expandable house on the market can say the same: the structure of this house carries CE marking with a European notified body, not just voluntary checks.
- CE marking to EN 1090-1, execution class EXC3 (system 2+): factory production control audited by a European notified body. Certificate verifiable online.
- S235JR structural steel (equivalent to Q235B under EN 10025-2), galvanised and powder coated.
- Technical documentation: Declaration of Performance (DoP) and CE certificate available to the customer and their engineer.
- ISO 9001:2015: the factory's quality management system (valid until 2028).
