When purchasing hot-rolled structural steel, the material is exposed to intense heat and mechanical deformation. This process affects the material's microstructure, potentially introducing defects or variations in strength.
A valid EN 10204 PDF must contain specific information to be compliant. When receiving your hot-rolled steel documentation, ensure the PDF includes: Product Description & Dimensions. Heat Number (Must match the stamp on the steel plate/pipe). Grade of Material (e.g., ASTM A516 Gr 70, S355NL). Chemical & Mechanical Analysis.
If the PDF says "Reference to heat analysis available upon request," that is not a valid 3.1 hot certificate. That is a 2.2 document.
The core of EN 10204 is the classification of certificates into four distinct types, with higher numbers indicating more rigorous testing and a greater level of assurance. en 10204 pdf hot
Because EN 10204 certificates are heavily circulated digitally as PDFs, they are vulnerable to fraudulent alterations. Always check for official stamps, signatures, and clear heat number traceability.
A statement validating that the delivered products comply with the order. No test results are included.
Imagine a high-stakes project: building a high-pressure natural gas pipeline. The engineering team cannot simply take a supplier's word that the steel pipes are strong enough. They require an —the most rigorous type available. When purchasing hot-rolled structural steel, the material is

If you receive an email with "EN 10204" and a spreadsheet of heat numbers, use a PDF automation tool (like Adobe Acrobat Pro or Power Automate) to extract and rename the PDFs to [Heat_Number]_EN10234.pdf . Chemical & Mechanical Analysis
Yes, but be careful. Many "free" templates are outdated or do not meet the 3.1 signature requirements. Use them only for training, not for actual shipments.
Similar to 3.1, it includes specific batch test results.
Without this documentation in PDF format, verifying the compliance of hot-rolled materials, especially for critical applications like pressure vessels, oil & gas pipes, or structural steelwork, is impossible. Deep Dive: EN 10204 3.1 vs 3.2
