EN 10025 Structural Steel Standards Explained: EN 10025-2, -3, -4 and -5

EN 10025 is a key European standard series for hot-rolled structural steel products. Different parts of the standard address different categories of structural steels and their technical requirements.

For buyers sourcing European structural steel, understanding the applicable EN 10025 part is essential.

EN 10025-2

EN 10025-2 covers hot-rolled non-alloy structural steels.

Common grades include:

S235JR

S235J0

S235J2

S275JR

S275J0

S275J2

S355JR

S355J0

S355J2

S355K2

These steels are widely used in general structural applications.

EN 10025-3

EN 10025-3 covers normalized or normalized rolled weldable fine grain structural steels.

Common grades include:

S275N

S275NL

S355N

S355NL

These grades are selected when higher toughness and fine-grain structural performance are required.

EN 10025-4

EN 10025-4 covers thermomechanically rolled weldable fine grain structural steels.

Typical grades include:

S275M

S275ML

S355M

S355ML

These grades can be used for structural applications requiring specific strength, toughness, and weldability characteristics.

EN 10025-5

EN 10025-5 covers structural steels with improved atmospheric corrosion resistance.

One example included in the supplied specification is S355J0W.

These steels are designed for applications where improved resistance to atmospheric corrosion is required.

How Union Steel Industry Supports EN Standard Projects

At Union Steel Industry, we understand that international structural steel procurement requires more than simply choosing a steel grade.

We can work according to the customer's:

EN standard

Steel grade

Section type

Dimensions

Thickness

Length

Delivery condition

Inspection requirements

This specification-based approach helps reduce material mismatches and makes structural steel procurement more efficient.
