Navigating the world of European steel standards can be complex. For professionals sourcing structural components, understanding the distinction between EN 10219 and EN 10025 is crucial for project success. While both are fundamental in the European market, they govern completely different aspects of steel products.
In short, EN 10025 defines what the steel is, while EN 10219 defines what the final product is.
This guide will break down these differences in simple terms, helping you make an informed decision for your next project.
Part 1: Core Concepts – Material vs. Finished Product
The most significant difference lies in the scope of each standard. One pertains to the raw material, and the other to a fabricated product made from that material.
EN 10025: Hot-Rolled Structural Steel Products This standard series specifies the technical delivery conditions for flat and long hot-rolled products, such as plates, sheets, coils, and sections (like I-beams and angles). Think of EN 10025 as the recipe for the steel itself. It defines the chemical composition, mechanical properties (like yield strength and tensile strength), and technological requirements (such as weldability and impact toughness) for various steel grades. Essentially, it answers the question: “What are the properties of this base steel material?”
EN 10219-1: Cold-Formed Welded Structural Hollow Sections This standard, on the other hand, focuses on a specific type of finished product: hollow sections (square, rectangular, and circular) that are manufactured by cold-forming and welding together steel plates or strips. EN 10219 uses steel that conforms to standards like EN 10025 as its starting raw material. It then sets the requirements for the manufacturing process, dimensional tolerances, and weld quality of the final tubular product.
Part 2: Key Differences at a Glance
The following table outlines the fundamental distinctions between these two standards.
Practical Implications:
If you are purchasing steel plates to fabricate your own components, you would specify EN 10025 and the required grade (e.g., S355).
If you are purchasing ready-made square or circular tubes for a structural frame, you would specify EN 10219.
Part 3: Choosing the Right Standard for Your Project
Your choice depends entirely on your project’s requirements.
✔️ When to Specify EN 10025: Specify EN 10025 when your project involves custom fabrication where you need certified base materials. This is common in heavy machinery, shipbuilding, and the construction of large-scale structural frameworks built from plates and beams.
✔️ When to Specify EN 10219: Choose EN 10219 when your design calls for precision cold-formed steel pipes and tubes. These are celebrated for their high dimensional accuracy and smooth surface finish, making them ideal for architectural aesthetics, intricate structural supports, and machine frames where exact fit-up is essential.
