Customizable Structural Steel Lattice Columns

Our factory-direct structural steel lattice columns are precision-fabricated from certified Q355B/S355JR (equivalent to ASTM A572 Grade 50) steel. Engineered for an optimized strength-to-weight ratio, these columns provide exceptional load-bearing capacity for demanding environments. We offer full-scale custom fabrication based on your Tekla or CAD drawings, specifically tailored for industrial warehouses, transmission towers, and complex wide-span infrastructures.

Based on different bracing configurations, lattice columns fall into two main categories: batten-plate type and laced type.

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:

1.Certified Shop Drawings：Full 3D detailing and shop drawings provided for your approval before production.

2.Full Material Traceability ：Each component is supplied with MTC 3.1 (Mill Test Certificates) ensuring 100% material compliance.

3.Stringent Weld Inspection：100% Visual Inspection + Ultrasonic/Magnetic Particle Testing reports as per international standards.

4.Trial Assembly & Fit-up： Critical sections undergo shop pre-assembly to guarantee seamless onsite installation.

 

Batten-plate Lattice Column

Structure: Constructed with main chords connected by horizontal steel batten plates perpendicular to the axis.

 

Key Advantage: Provides a clean, rigid frame behavior. It is easier to fabricate and inspect, making it a cost-effective solution for medium-height columns and members with lower lateral load requirements.

 

Best For: Workshop interior columns, pipe racks, and equipment supports.

 

Laced Lattice Column

Structure: Features a triangulated truss system using angle steel or pipes as diagonal lacing bars.

 

Key Advantage: Offers superior overall stiffness and torsional resistance. The truss-like configuration is 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.

 

1. Superior Structural Stability 

By expanding the distance between chords, lattice columns significantly increase the Moment of Inertia and Radius of Gyration. This effectively lowers the Slenderness Ratio, providing much higher resistance to axial buckling compared to solid-web columns.

2. 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.

3. Optimized Logistics & Faster Installation

Due to their lightweight yet rigid nature, lattice 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.

4. 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.

5. Functional Integration Capability

The internal void within the lattice framework allows for the integrated routing of industrial utilities such as pipes, electrical cables, and drainage systems, optimizing the use of architectural space.

1.Building Support: Applied as frame columns and standalone columns in construction frameworks to deliver high load-bearing capacity and structural stability.

2.Bridge Construction: Used for bridge piers and pylons, offering outstanding load capacity and seismic resistance.

3.Tower Structures: Ideal for high-rise telecommunication & power transmission towers with reliable wind resistance and overall stability.

4.Industrial Equipment: Serves as supporting frames for cranes, conveyors and other industrial machinery, featuring superior load capacity and long-term durability.

1. Professional Shop Detailing 

Converting architectural designs into precise fabrication models and shop drawings to ensure 100% structural accuracy.

2.High-Precision CNC Cutting

Precision cutting of heavy steel plates and complex sections, including beveling for high-strength weld preparations.

3. Advanced Structural Welding

Certified welding for chords and lacings under AWS D1.1/EN standards, ensuring maximum penetration and load-bearing integrity.

4. CNC 3D Drilling & Punching

 Automated drilling for high-strength bolt connections to guarantee perfect hole alignment during onsite assembly.

5. Mechanical Straightening & Correction

Correcting post-welding thermal deformation to ensure the strict verticality and straightness of long lattice columns.

6. Industrial Surface Treatment

Achieving Sa 2.5 cleanliness via shot blasting, followed by high-performance anti-corrosion coating or hot-dip galvanizing.

7. Shop Trial Assembly

Mandatory pre-assembly of critical column segments to eliminate onsite installation risks and ensure seamless fit-up.

1.Steel Frame Bundling

Columns are secured on customized steel cradles to prevent structural bending and deformation during transit.

2.Node & Flange Protection

All connection flanges and bolt holes are shielded with plywood or rubber caps to prevent rust and impact damage.

3.Paint Finish Preservation

 Edges are wrapped with EPE foam or anti-friction padding to avoid scratches and maintain coating integrity.
