Regulations and certification

The most common questions are not about the structure but about the paperwork: is an NMÉ needed, how ETA differs from CE, and what proves the fire protection. This knowledge base answers them from design practice. On a specific project the authority and the responsible designer always have the final word.

In this knowledge base

• Certification — certifications overview, NMÉ, ETA, CE, the target certificate
• Fire protection — fire protection for thin-walled steel
• Permits and checks — permitting, statutory design check or expert review
