Galvanized H Beam is one of the common forms of galvanized structural steel. It features a hot-dip galvanized H-shaped cross-section with wide, uniform-thickness flanges and a straight transition between the web and flanges. It combines the superior bidirectional load-bearing capacity of H-section steel with the corrosion resistance and weathering advantages of the galvanized coating.

- H – Section height, B – Flange width, t₁ – Web thickness, t₂ – Flange thickness.
- HW denotes wide-flange H-section steel, HM denotes medium-flange H-section steel, HN denotes narrow-flange H-section steel.
Classification by Type
- Wide-flange H-section (HW): Flange width is nearly equal to height. Features wide flanges and high sectional moment of inertia, offering excellent bending and compression resistance with superior overall stability.
- Medium-flange H-section (HM): Flange width lies between wide-flange and narrow-flange types. Moderate width balances load-bearing capacity and cost-effectiveness, providing well-rounded performance.
- Narrow Flange H-Beam (HN): Features narrow flanges and a taller web, prioritizing unidirectional bending performance optimization. Offers more economical material distribution when used as beams.
Applications
- Construction Engineering: Main beams for industrial plants, high-rise steel structure beams/columns, load-bearing frameworks for light steel buildings, spatial load-bearing structures for large venues, main floor beams.
- Bridge Engineering: Internal cross-girders/main girders for long-span box girders, pier supports, bridge guardrail supports.
- Machinery Manufacturing: Heavy machinery bases, crane main girders, mining conveyor supports.
- Municipal & Energy: Urban rail transit platform structures, main components for power transmission towers, main steel structures for large billboards, internal supports for wind turbine towers.
Advantages of Galvanized H-Beams
Exceptional Structural Stability
- Galvanized H-beams feature high bidirectional moment of inertia, delivering superior combined bending, compression, and torsion resistance for complex load-bearing applications.
Superior Corrosion Resistance and Durability
- The hot-dip galvanized coating (with a maximum thickness of 600g/m²) provides long-term cathodic protection, making it suitable for outdoor, humid, and industrial atmospheric environments with a service life exceeding 30 years.
Ease of Fabrication and Installation
- Hot-dip galvanized steel can be cut, drilled, and welded as needed. The coating exhibits strong adhesion and resists peeling after processing. As a standard rolled profile, it offers high dimensional accuracy and facilitates efficient construction through high-strength bolted connections.
High Material Utilization
- Optimized cross-sectional distribution enables steel savings compared to alternative profiles while maintaining equivalent load-bearing capacity. This offers significant economic benefits, particularly in long-span, heavy-load structures.
Outstanding Overall Benefits
- Although the per-ton cost exceeds that of galvanized I-beams, the overall project cost proves more advantageous in long-span and complex loading scenarios.
Galvanized H Beam vs Galvanized Steel I Beam
| Comparison Item | Galvanized H Beam | Galvanized I Beam |
| Cross – Section Shape | In the shape of “H” | In the shape of “I” |
| Flange Characteristics | The inner and outer surfaces are parallel, with wide flanges and uniform thickness | The inner surface has an inclination, with narrow flanges, being thick inside and thin outside |
| Mechanical Properties | Good biaxial bending resistance and strong torsional resistance | Excellent uniaxial bending resistance and weak torsional resistance |
| Applications | Columns, large – span (≥12m) beams, biaxial – loaded frames | Uniaxial – bending beams, horizontal members with small to medium spans |
| Connection | Easy to connect | Often requires wedge – shaped shims |
| Economy | High comprehensive load – bearing efficiency | Highest material utilization when used as a uniaxial beam |
