European standard H sections and I beams: sizes, grades and applications

European-standard H sections and I beams are widely used in structural engineering because their cross-sectional geometry provides efficient load-bearing performance while supporting standardized design and procurement.

The supplied technical schedule covers heavy, middle, and light H steel section lines, with different dimensional ranges and EN 10025 steel grades.

Heavy H Sections

The documented heavy H section range includes dimensions up to approximately:

H section: 1000 × 302 mm

Thickness: approximately 12–40 mm

The corresponding material range includes grades such as:

S235JR

S235J0

S235J2

S275JR

S275J0

S275J2

S355JR

S355J0

S355J2

S355K2

The same schedule also covers I-beam products up to approximately 630 × 180 mm, with thickness ranges specified according to the applicable grade and standard.

Middle H Sections

The middle H section range includes sizes up to approximately:

H 400 × 200 mm

The documented thickness range is approximately 6.5–18 mm, depending on the applicable standard and product type.

I beams and C beams are also included within the middle-section product range.

Light H Sections

The light H section range includes:

H 200 × 100 mm

with thicknesses generally within approximately 7–12 mm in the documented range.

The product schedule also covers I beams, C beams and L sections in corresponding dimensional ranges.

Why Section Size Matters

Selecting a structural section should not be based on nominal height alone.

Engineers and buyers should consider:

Section height

Flange width

Web thickness

Flange thickness

Steel grade

Span

Applied load

Connection design

Structural stability

A larger section does not automatically mean a better solution. The section must match the engineering design and loading conditions.
