A steel lattice column is a vertical load-bearing structural member composed of main chords connected by batten plates or lacing bars in a triangulated or grid pattern. Its open-web design concentrates steel at the perimeter where stress is highest, delivering a superior strength-to-weight ratio - typically saving 15%–25% steel versus solid-web columns. We provide factory-direct lattice column fabrication to your Tekla or CAD drawings, certified to AWS D1.1 / EN 1090 / AISC standards.
Types of Steel Lattice Columns - Batten-Plate vs Laced
Based on different bracing configurations, lattice columns fall into two main categories: batten-plate type and laced type. Both share the same engineering principle - expanding the distance between chords to increase the Moment of Inertia and reduce the Slenderness Ratio - but differ in construction and optimal use cases.
Batten-plate Lattice Column
Structure: Main chords connected by horizontal steel batten plates perpendicular to the column axis.
Key Advantage: Provides clean, rigid frame behavior. Easier to fabricate and inspect, making it a cost-effective solution for medium-height columns with lower lateral load requirements.
Best For: Workshop interior columns, pipe racks, and equipment supports.
Laced Lattice Column
Structure: Triangulated truss system using angle steel or pipes as diagonal lacing bars.
Key Advantage: Offers superior overall stiffness and torsional resistance. Designed to handle significant slenderness ratios and heavy vertical loads without compromising structural integrity.
Best For: Heavy-duty industrial cranes, high-voltage transmission towers, and large-span infrastructure.
Regardless of the configuration your project demands-whether Battened or Laced-our commitment to structural integrity and engineering precision remains the same.For every lattice column we fabricate, our standard delivery package includes: certified shop drawings (3D detailing for approval before production), full material traceability (MTC 3.1), stringent weld inspection (100% Visual + UT/MT reports), and trial assembly of critical sections.

Features & Advantages of Steel Lattice Columns
Superior Structural Stability
By expanding the distance between chords, lattice columns significantly increase the Moment of Inertia and Radius of Gyration, effectively lowering the Slenderness Ratio and providing much higher resistance to axial buckling compared to solid-web columns.
01
Significant Material & Cost Efficiency
The hollow configuration concentrates steel at the perimeter where stress is highest, eliminating the "dead weight" of a central web. This typically results in 15%–25% steel savings in large-scale industrial frames, directly reducing overall project costs.
02
Optimized Logistics & Faster Installation
Due to their lightweight yet rigid nature, lattice steel columns require smaller capacity cranes, reducing onsite lifting costs by approximately 20%. Their modular design and high factory pre-fabrication precision ensure seamless onsite assembly with minimal rework.
03
Versatile Engineering Adaptability
Lattice columns can be precisely engineered into various geometries (two-leg, four-leg, or star-shape) to withstand specific wind or seismic loads. They are the ideal solution for extra-tall structures (50m+) and large-span infrastructures where solid sections are not feasible.
04
Functional Integration Capability
The internal void within the lattice framework allows for integrated routing of industrial utilities such as pipes, electrical cables, and drainage systems, optimizing architectural space.
05
Lattice Column vs Solid-Web Column - Why Choose Lattice?
| Metric | Steel Lattice Column | Solid H-Section Column |
|---|---|---|
| Steel usage | 15–25% less | Baseline |
| Self-weight | Significantly lower | Heavier |
| Slenderness ratio | Lower (larger gyration radius) | Higher |
| Max practical height | 50m+ feasible | Economically limited |
| Foundation load | Reduced | Higher |
| Internal utility routing | Yes (hollow core) | No |
| Crane capacity needed | ~20% smaller | Larger crane |
For tall, slender, or large-span structures where weight and wind resistance matter, lattice steel columns are the engineered choice over solid sections.

FAQ:
What is a steel lattice column and when should I use one?
A steel lattice column is a vertical load-bearing member with an open-web design of chords and lacing bars. Use it for tall structures (50m+), large-span buildings, heavy crane supports, and transmission towers where a high strength-to-weight ratio and wind resistance are critical. It typically saves 15–25% steel versus solid H-section columns.
Batten-plate vs laced lattice column - which type do I need?
Choose batten-plate type for medium-height columns, pipe racks, and equipment supports - it's easier to fabricate and more cost-effective.
