HEA, HEB and HEM Steel Beams: Differences, Technical Specifications and Applications
HEA, HEB and HEM steel I-beam sections are widely used in construction, industry, and structural steel fabrication. Although these profiles look similar in appearance, they differ in dimensions, web and flange thicknesses, weight, and cross-sectional properties.
These profiles are primarily used in the fabrication of various load-bearing structures.
1. HEA – Light Series I-Beam Section
HEA is a wide-flange steel I-beam section with a relatively lightweight structural design. Its lower unit weight makes it a suitable choice for various construction projects.
Main applications:
- Building and construction frameworks;
- Industrial and warehouse buildings;
- Load-bearing columns and beams;
- Structural steel fabrication;
- Various engineering projects.
2. HEB – Standard Heavy Series I-Beam Section
Compared to HEA, HEB sections have thicker flanges and webs. For the same nominal size, they have a higher mass and generally provide greater cross-sectional properties.
Main applications:
- Load-bearing columns;
- Multi-storey buildings;
- Industrial facilities;
- Heavy steel structures;
- Manufacturing and warehouse complexes.
3. HEM – Extra Heavy Series I-Beam Section
HEM sections have a heavier and thicker structural design than HEA and HEB series. Their robust cross-sectional properties make them suitable for structures designed to withstand high project loads.
Main applications:
- Heavy industrial structures;
- Large load-bearing columns;
- Bridges and engineering structures;
- High-load steel structures;
- Heavy manufacturing facilities.
4. Technical Differences Between HEA, HEB and HEM
| Characteristic | HEA | HEB | HEM |
|---|---|---|---|
| Profile series | Light | Heavy | Extra Heavy |
| Flange thickness | Relatively thin | Thicker | Thickest |
| Web thickness | Relatively thin | Thicker | Thickest |
| Unit weight | Low | Medium | High |
| Applications | General construction | Heavy structures | High-load structures |
Note: This comparison provides general characteristics for the same nominal size. Actual load-bearing capacity depends on the profile dimensions and project conditions.
5. Dimensions and Weight Comparison
Example based on the nominal 200 series:
| Technical Specification | HEA 200 | HEB 200 | HEM 200 |
|---|---|---|---|
| Height (mm) | 190 | 200 | 220 |
| Flange width (mm) | 200 | 200 | 206 |
| Weight per metre (kg) | 42.3 | 61.3 | 103 |
Approximate weight of a 12-metre-long section:
- HEA 200 – 507.6 kg
- HEB 200 – 735.6 kg
- HEM 200 – 1,236 kg
6. Technical Standards
The following European standards are used to define the manufacturing requirements and technical specifications of HEA, HEB and HEM steel sections:
EN 10365:2026 – Hot Rolled Steel Channels, I and H Sections – Dimensions and Masses
This standard specifies the nominal dimensions and masses per unit length of hot-rolled U, I and H steel sections. HEA, HEB and HEM profiles are included within its scope.
EN 10034 – Structural Steel I and H Sections – Tolerances on Shape and Dimensions
This standard specifies the permissible dimensional and shape tolerances for structural I and H steel sections.
EN 10025-1 – Hot Rolled Products of Structural Steels – General Technical Delivery Conditions
This standard defines the general technical delivery conditions for hot-rolled structural steel products.
EN 10025-2 – Technical Delivery Conditions for Non-Alloy Structural Steels
This standard specifies the technical delivery conditions and requirements for grades of non-alloy structural steels.
7. Which Profile Should You Choose?
The choice between HEA, HEB and HEM depends on the technical requirements of the project, applied loads, span length, and operating conditions of the structure.
The following factors should be considered when selecting the appropriate profile:
- Profile dimensions and weight;
- Steel grade;
- Web and flange thicknesses;
- Load-bearing capacity;
- Engineering calculations and project specifications.
