EN 10025-2 PDF – Complete Guide to Hot-Rolled Structural Steel Standards
If you’re searching for “EN 10025-2 PDF” to understand technical delivery conditions for non-alloy structural steels, you’re in the right place. This guide breaks down the EN 10025-2:2019 standard and answers the most common questions related to its application in construction, engineering, and manufacturing.
✅ Key focus: Understanding EN 10025-2:2019, its scope, technical specifications, and how it impacts material selection and project safety.
📘 What is EN 10025-2?
EN 10025-2:2019 is the European Standard that specifies the technical delivery conditions for hot-rolled non-alloy structural steels. It is part of the broader EN 10025 series, which is widely used in steel construction and fabrication industries across Europe and globally.
This version (2019) supersedes EN 10025-2:2004 and reflects updated requirements in manufacturing, inspection, and compliance.
🔍 Why Does EN 10025-2 Matter?
This standard ensures that structural steels used in buildings, bridges, towers, and industrial plants meet consistency, strength, and safety standards. It provides manufacturers, engineers, and purchasers with a uniform reference for:
- Mechanical and chemical properties
- Production methods
- Inspection requirements
- Labeling and packaging
- Sampling and testing frequency

🧪 Key Technical Parameters in EN 10025-2
The standard outlines specifications for structural steel grades such as S235, S275, S355, and others, focusing on:
📌 Mechanical Properties:
Yield strength and tensile strength
Elongation at break
Impact energy (Charpy V-notch tests) at specified temperatures
🧬 Chemical Composition:
Limits for elements like C, Mn, Si, P, S, N, Al
Requirements differ slightly by grade and steelmaking method (e.g., boiling, killed, semikilled steels)
🛠 Testing Protocols:
Sampling per Annex A
Test frequencies per product category
Validated testing methods including impact, tensile,
✅ Advantages of Using EN 10025-2 Compliant Steels
Regulatory compliance across the EU and internationally
Predictable performance under static and dynamic loads
Improved safety in civil and structural engineering applications
Traceability and quality assurance for steel sourcing
Compatibility with EN 1090 (steel structure fabrication)
🔄 EN 10025-2 vs. EN 10025-1
While EN 10025-1 lays the general requirements for all parts of the standard, EN 10025-2 focuses specifically on non-alloy steels. Other parts cover alloyed, thermomechanically rolled, quenched, or normalized steels.
