1. What is EN1090 Certification for Steel Structures?

EN 1090 is a mandatory EU standard for steel and aluminum structural components. According to the EU Construction Products Regulation (CPR 305/2011), all steel and aluminum structural products exported to the EU market (such as steel beams, columns, welded building components, etc.) must comply with EN 1090 and bear the CE mark, otherwise they cannot be legally sold or installed in the EU market.

EN 1090 mainly consists of the following parts:

EN 1090-1: Conformity assessment and CE marking requirements for components
EN 1090-2: Technical requirements for steel structures
EN 1090-3: Technical requirements for aluminum structures

2. Why is EN1090 Certification Required for Steel Structures?

2.1 Legal Requirement
EU Construction Products Regulation clearly states that steel structure products entering the market must comply with EN 1090 standards.

2.2 Smooth Customs Clearance, Avoiding Detention
Products without CE marking will be rejected or returned during customs clearance and project acceptance.

2.3 Enhanced Market Competitiveness
Having EN 1090 certification increases product recognition in the EU market and builds customer trust.

2.4 Reduced Project Risk
EN 1090 certification is not only a compliance requirement but also a guarantee of welding quality and structural safety.

3. Scope of EN1090 Certification for Steel Structures

✓ Steel structure components (beams, columns, trusses, bridges, prefabricated parts, etc.)
✓ Welded structural components for construction projects
✓ Aluminum structure components
✓ Factory steel structures, load-bearing components, railings, etc.

4. EN1090 Certification Process

4.1 Application and Documentation Preparation
• Company basic information
• Product description and design documents
• Factory Production Control (FPC) system documents

4.2 Factory Production Control (FPC) Audit
• Welding quality management system (ISO 3834)
• Welder qualification certification (EN ISO 9606)
• Welding procedure qualification (WPS, WPQR)

4.3 Product Testing and Verification
• Mechanical performance testing
• Dimensional deviation, weld quality inspection

4.4 Certificate Issuance and CE Marking
• Obtain EN1090 certificate
• Products can legally enter the EU market only after being CE marked

5. Common Questions

Q: Do all steel structure products require EN1090 certification?
A: All load-bearing steel components exported to the EU and used in construction projects must have EN 1090 certification.

Q: What is the relationship between EN 1090 certification and ISO 3834?
A: ISO 3834 is the core system for welding quality management and forms the basis of EN1090 Factory Production Control (FPC), with the two closely related.

Q: How long is the certificate valid?
A: The certificate is typically valid indefinitely, but the factory must undergo annual surveillance audits.

Summary

EN1090 certification is not only a "passport" to enter the EU market but also recognition of a company's quality management and product safety. Obtaining EN1090 certification in advance can not only avoid customs clearance risks but also enhance a company's international competitiveness.
