Steel Lattice Column

A steel lattice column is a vertical load-bearing structure made from multiple slender steel members (often angles, channels, or tubular sections) arranged in a lattice or truss-like pattern. This open-web configuration reduces weight while maintaining high strength, making it a cost-efficient alternative to solid-section columns for certain applications.

Structural Composition

Built from three or four main vertical chords connected with diagonal bracing.
Members are typically hot-rolled steel angles or tubular sections.
Connections made by bolting, riveting, or welding.

Design Benefits

Lightweight: Less steel volume compared to solid sections.
High Load Efficiency: Transfers loads through triangulated bracing.
Wind Resistance: Open lattice reduces wind drag on tall structures.
Ease of Transport: Can be prefabricated in sections for assembly on-site.

Material Options

Common grades: Q235B, Q355B, ASTM A36, S275JR, S355JR.
Galvanized or painted for corrosion protection.

Surface Treatments

Hot-dip galvanizing for outdoor durability.
Industrial epoxy or polyurethane coatings for marine/coastal use.

Applications

Transmission Towers – Power line support columns.
Communication Masts – Radio, TV, and mobile network towers.
Industrial Buildings – Long-span roof supports in factories.
Bridges – Lattice piers for railway or pedestrian bridges.
Cranes – Column supports for gantry cranes and tower cranes.

Advantages

Material Savings: Lower steel consumption than equivalent solid sections.
High Strength-to-Weight Ratio: Ideal for tall and long-span structures.
Adaptability: Can be designed for varying loads and environmental conditions.
Reduced Wind Load: Open structure minimizes aerodynamic resistance.
