What an H-Beam Is
An H-beam is a structural steel section with an H-shaped cross-section made up of two parallel flanges and a connecting web. Because the material is concentrated away from the neutral axis, the profile delivers high bending stiffness per unit weight and is the standard choice for columns and beams in steel structures.
HEA, HEB and IPE Section Series
The HEA, HEB and IPE series are European section families whose dimensions and tolerances are set out in EN 10034. HEA and HEB are wide-flange sections: HEA has a lighter flange for weight-sensitive frames, while HEB carries a heavier flange for higher loads. IPE is the I-shaped series with a narrower flange, used mainly as beams for roofs and floors.
HEA sections for columns and beams in low and medium load frames.
HEB sections for heavy columns and high-capacity members.
IPE sections for economical long-span beams.
Material Grades
ASTM A36 provides general structural carbon steel with a minimum yield strength suitable for most building frames. ASTM A572 Grade 50 offers higher strength for longer spans and heavier loads. S355 to EN 10025 is the European high-strength structural grade with a minimum yield strength of 355 MPa, widely specified in modern steel design.
Surface Finishes
Sections are delivered with a black hot-rolled surface for protected interiors or with hot-dip galvanizing for outdoor and corrosive service. Galvanized H-beams are common in industrial sheds, substations and open steel frames where long maintenance-free life is required.
Applications
Columns and beams of industrial and commercial steel buildings.
Portal frames, roof trusses and mezzanine structures.
Crane runway girders and heavy equipment supports.
Steel bridges, platforms and access structures.
Frequently Asked Questions
Q: What is the difference between HEA and HEB sections?
HEA sections have lighter flanges and lower weight for the same nominal height, while HEB sections have heavier flanges and greater load capacity.
Q: Which grade should be used for a high-load column?
For high loads, A572 Grade 50 or S355 is preferred over A36 because of the higher yield strength and reduced section weight.
Q: Are the sections supplied to EN 10034 tolerances?
Yes, the dimensions, mass and straightness of the sections are verified against EN 10034 requirements.
Q: Can galvanized H-beams be welded?
Galvanized sections can be welded, but the zinc coating should be removed locally around the weld area and ventilation maintained during welding.
Q: What documentation is provided with each delivery?
Mill test certificates with chemical composition and mechanical properties are supplied for each heat of steel.
