An H-section column is the vertical axial-load member of a steel frame, and its wide-flange H profile distributes material efficiently so the member carries heavy vertical loads with good lateral stability against buckling. Shown for both workshops and multi-storey frames, our structural steel H-section columns are precision-manufactured to internationally recognised standards (GB/T 11263, EN 10025, AS/NZS 3678, ASTM A572) in high-strength grades Q355B/S355JR to A572 Gr50, welded by automatic Submerged Arc Welding where a welded column is specified.
We supply uniform, tapered and wedge-shaped profiles so the member follows the bending-moment envelope of a light portal frame instead of wasting steel on a constant section, with column base plates, anchor-bolt layouts and splice details drawn in Tekla. Finished with shot blasting and certified anti-corrosive coating, every column ships with an MTC and 100% UT inspection, quoting within 24 hours.

Types of H-Section Column
H-section steel columns are widely used in steel structure projects. Based on cross-section variation and profile along the height, they fall into three main types: uniform-section H-columns, tapered H-columns and wedge-shaped H-columns.
Whether your project requires uniform-section columns for standard stability or tapered/wedge-shaped designs for optimized material efficiency in large-span portals, our engineering team ensures that every profile is calculated for maximum load-bearing performance and structural integrity.
Wedge-Shaped H-Columns
Features: Vertical 90° on one side, inclined edge on the other.
Advantages: Perfectly accommodates changing bending moment. Used with tapered roof rafters to improve cost efficiency.
Applications: Side & interior columns of light portal frame steel buildings.
Tapered H-columns
Features: Both sides are inclined edges.
Advantages: Optimized material layout according to stress distribution. Lightens the structure while maintaining sufficient load capacity.
Applications: Tapered columns for light portal frames.
Uniform-Section H-columns
Features: Both sides are vertical at 90°.
Advantages: Uniform load bearing and clear stress distribution. High standardization simplifies fabrication and on-site installation.
Applications: Widely used as constant-height bent columns in multi-storey frame structures and industrial workshops.
Core Advantages of H-Section Column
1. Excellent Mechanical Properties
The flanges and web of H-section steel columns work in synergy, delivering strong biaxial bending resistance, high load capacity and outstanding torsion resistance. Its load-bearing capacity per unit weight is 15% higher than that of I-section steel columns.
2. Higher Space Utilization
Flange thickness can be reduced by 30% without compromising structural strength. Preformed standard holes facilitate pipeline installation. The slim web design saves joint space and maximizes usable floor area.
3. Easy Lifting Operations
It is 50% lighter than concrete columns, cutting tower crane working time by 40%.
4. Flexible Connections
Pre-drilled bolt holes are manufactured to high precision, enabling fast on-site assembly without field welding.
5. Reliable Construction Schedule
Construction can proceed regardless of weather conditions. Work continues even on rainy or snowy days, with no curing period required.
Production Process of H-Section Column
The professional fabrication of our H-section steel columns integrates advanced Tekla BIM detailing with precision CNC material preparation, automated assembly, and high-strength Submerged Arc Welding (SAW), followed by mechanical straightening and secondary component integration, all strictly verified through Non-Destructive Testing (NDT/UT) before concluding with Sa 2.5 shot blasting and certified anti-corrosive coating to ensure maximum structural integrity and durability for global export projects.

Selection Guide - Section per Use Case
The table below is carried from general industrial selection practice; each section is double-checked against your actual span, crane load and steel grade before fabrication.
| Use case | Typical sections (mm) | Key selection point |
|---|---|---|
| Light industrial building (roof truss / column) | H200×100 · H250×125 | Lightweight, moderate span |
| Heavy industrial building (main beam / crane beam) | H400×200 · H500×200 · H600×300 | High strength, large span, rail loads |
| Multi-storey / high-rise frame | H300×200 · H350×250 · H400×300 | High axial pressure, good stability |
| Bridge main / secondary beam | H500×200 · H600×300 · H700×300 | High bending strength, durability (thickened flange optional) |
| Warehouse / logistics frame | H250×125 · H300×150 | Lightweight, fast erection |
| Power / tower support | H300×200 · H350×250 | High shear and wind resistance |
| Outdoor / corrosive (wind energy etc.) | H400 and above, hot-dip galvanized | Fatigue and corrosion resistance |
Quick selection guide by span
Small span (<12 m): H200–H300.
Medium span (12–24 m): H300–H500.
Large span or crane beam: H500 and above.
For columns, choose thicker flanges with a thinner web; for beams, a thicker web strengthens bending.

FAQ:
How is an H-section column fixed to the foundation?
Columns sit on a concrete foundation through a base plate cast with anchor bolts; after erection the base is grouted and the nuts torque-tightened. Anchor-bolt layout, base-plate size and levelling nuts can be supplied per your foundation drawing.
What verticality tolerance is achievable, and how is the column straightened?
Column verticality is checked by theodolite/level after temporary holding; the industry-aligned tolerance is lean within H/1000 and not more than 25 mm for storey-height columns, then the base is grouted and finalised.
Welded H-section or hot-rolled H-beam - how do I choose the form?
Hot-rolled H-beams suit standard sections with fast delivery and low cost; welded H-sections fit non-standard depths, tapered or wedge shapes and heavier flanges, and let you optimise the section to the moment envelope. Both meet the same strength grades.
Do you provide fire and corrosion protection for the column?
Corrosion protection is by Sa 2.5 shot blasting plus epoxy zinc-rich primer with a top coat, or hot-dip galvanizing for outdoor use; fire resistance can be met with intumescent coating or concrete encasement to the required fire-rating period.
How are axial load, slenderness and second-order effects considered?
The column is checked for axial compression, biaxial bending and buckling capacity under the governing lean, and second-order (P-delta) effects from column deflection are included, per AISC 360 / EN 1993 / GB 50017, so the section stays stable under factored loads.
Are splicing joints and base details supplied?
Yes. Shop or site splices with splice plates and high-strength bolts, base plates, base stiffeners and anchor-bolt details are detailed in Tekla and supplied, sized to keep erection simple and the joint stiffness continuous.
