European standard structural steel sections: grades, standards, sizes and applications

European standard structural steel sections are widely used in buildings, industrial facilities, bridges, warehouses, infrastructure projects, and other load-bearing structures. Their standardized dimensions, steel grades, and mechanical requirements make them suitable for projects that require consistent structural performance.

At Union Steel Industry, we supply structural steel products for international projects and can provide different European-standard grades, section types, dimensions, and delivery conditions according to project requirements.

What Are European Standard Structural Steel Sections?

European standard structural steel sections are hot-rolled steel profiles manufactured according to applicable EN standards. Common products include:

H sections

I beams

C sections

L sections

Round bars

Bulb flat steel

The applicable standard depends on the product type, steel grade, toughness requirement, and delivery condition.

Main EN Standards for Structural Steel

The document covers several standards within the EN 10025 series:

Common grades include S235, S275 and S355 series steels.

Common Steel Grades of European Standard Structural Steel Sections

Typical grades found in European structural steel applications include:

S235JR

S235J0

S235J2

S275JR

S275J0

S275J2

S275N

S275NL

S275M

S275ML

S355JR

S355J0

S355J2

S355K2

S355N

S355NL

S355M

S355ML

The exact grade should be selected according to the required strength, toughness, welding requirements, and service environment.

Common Structural Steel Sections

H Sections

H sections provide a favorable strength-to-weight ratio and are commonly used as columns and primary structural members.

I Beams

I beams are commonly used for beams, frames, platforms, and other load-bearing structures where bending resistance is important.

C Sections

C sections can be used for secondary structural members, supports, framing systems, and industrial structures.

European Structural Steel from Union Steel Industry

At Union Steel Industry, we focus on supplying steel products for demanding international applications. For European-standard structural steel, we can support customers with specifications covering:

Steel grade

Section type

Section dimensions

Wall or flange thickness

Length

Delivery condition

Inspection requirements

Surface requirements

For projects involving structural steel sections, providing the required EN standard + grade + section + dimensions is the most effective way to ensure accurate product selection.
