H-Beam Standard Sizes: HEA & HEB Steel Beam Specifications Explained

H-beams are widely used structural steel sections produced by hot rolling. In international markets, H-beams are most commonly supplied according to European Standard EN 10034, where the profiles are classified as HEA H Beam and HEB Steel Beam.

This article provides a technically accurate overview of H-beam standard sizes, with particular focus on HEA beam dimensions, HEB beam profile, and commonly referenced sizes such as H Beam 400 and H Beam 400x400.

Definition of Hot Rolled Carbon Steel H Beam

A hot rolled carbon steel H beam is a structural steel section with parallel flanges and a relatively wide flange width compared to traditional I-beams. The hot rolling process ensures:

Uniform mechanical properties

Stable cross-sectional geometry

Good weldability and machinability

Compliance with EN, ASTM, or JIS standards

H-beams are primarily used as load-bearing members in steel structures.

Understanding H-Beam Standard Sizes (EN System)

Under EN 10034, H-beams are standardized into different series, mainly:

HEA H Beam – lighter section

HEB Steel Beam – heavier section

The designation number (e.g. 400) refers to the nominal height in millimeters, not an arbitrary size.

H Beam 400x400 – Clarifying the Term

H Beam 400x400 typically describes an H-beam with:

Nominal height ≈ 400 mm

Flange width ≈ 400 mm

In the EN standard system, this geometry corresponds to:

HEA 400

HEB 400

Both profiles have flange widths close to their height, which explains why they are often marketed as 400x400 H beams, especially in column applications. However, the exact thickness and weight differ significantly between HEA and HEB.

HEA H Beam – Dimensions and Characteristics

HEA beams are designed as lighter structural members under EN standards.

HEA Beam Dimensions – Key Characteristics

Nominal height: 400 mm (for HEA 400)

Relatively thinner web and flange

Lower weight per meter compared to HEB

Suitable for medium-load structures

HEA H beams are commonly used for:

Secondary beams

Building frames

Columns with moderate axial loads

HEA vs HEB: Technical Selection Considerations

HEA vs HEB: Technical Selection Considerations

When selecting between HEA H Beam and HEB Steel Beam, engineers typically evaluate:

Axial and bending load requirements

Column or beam application

Span length and stability criteria

Project budget and installation conditions

Both profiles are fully standardized and interchangeable only after proper structural calculation.
