Questions & Answers
What is EN 1090-1 certification?
EN 1090-1 is the European standard governing the execution of structural steel and aluminium structures. It requires manufacturers to operate a certified Factory Production Control (FPC) system, ensuring consistent production quality, documented processes and compliance with CE marking requirements.
Why is EN 1090 important for container modifications?
Many engineered container modifications involve structural changes such as reinforced floors, equipment foundations, additional openings or load-bearing steel elements. EN 1090 certification demonstrates that these structural components are manufactured under controlled production procedures and recognized European quality requirements.
What is EN ISO 3834-3?
EN ISO 3834-3 defines quality requirements for fusion welding of metallic materials. It covers welding procedures, qualified personnel, inspection, documentation and quality control to ensure consistent and reliable welded structures.
Why is welding certification important?
Structural integrity depends heavily on welding quality. Certified welding procedures help ensure that modified container structures perform as intended under transportation, lifting and operational loads while maintaining repeatable manufacturing quality.
Are all POLKONT container modifications manufactured under certified processes?
Yes. Structural container modifications are manufactured under POLKONT’s certified production and welding quality systems in accordance with the scope of our EN 1090-1 and EN ISO 3834 certifications.
Does certification mean every container receives CE marking?
Not necessarily.
CE marking depends on the type of product, applicable legislation and project scope. Where required, POLKONT prepares the necessary engineering documentation and issues the appropriate Declaration of Conformity for structural modifications.
Who issued POLKONT’s certifications?
POLKONT’s EN 1090-1 and EN ISO 3834 certifications have been issued by TÜV SÜD, an internationally recognized independent certification organization.
Why should I choose a certified container engineering partner?
Working with a certified engineering partner provides greater confidence that structural modifications are designed, manufactured and documented using controlled processes. It reduces technical risk, supports regulatory compliance and simplifies supplier qualification for industrial and infrastructure projects.
What is the difference between EN 1090 and EN ISO 3834?
EN 1090 focuses on the execution of structural steel components and Factory Production Control, while EN ISO 3834 specifies the quality requirements for welding processes. Together, these certifications provide a comprehensive framework for manufacturing structural steel products with controlled production and documented welding quality.
