What Is a Steel Lattice Column?
A steel lattice column is a lightweight, high-strength steel structural load-bearing member, primarily composed of multiple angles, channels, or tubular main sections connected by lacing bars and batten plates to form a truss-type grid structure.
Main Components
Chord:Primary load-bearing members subject to axial compression and bending moment.
Lacing Components: Secondary force-resisting members that interconnect individual chords to enable composite structural action.
Gusset plates and connections: Used for the intersection, welded joints and bolted fastening between column chords and lacing bars.
Base plates and anchor bolts: Located at the bottom of columns, they evenly transfer the loads from superstructure to the foundation and provide full structural anchorage.

Types of Lattice Steel Columns
In structural engineering, the choice between lacing and battening depends on the magnitude of the shear force and the required rigidity of the column.According to the different connection components of the web structure, lattice steel columns are professionally divided into two mainstream types: laced lattice columns (laced columns) and lattice plate columns (batten plate columns).
| Item | Laced Steel Columns | Battened Steel Columns |
|---|---|---|
|
|
|
|
| Structural Composition | Built up from two or more steel sections connected by diagonal lacing bars (single or double lacing), forming a triangulated structural system for efficient load transfer and overall stability. | Built up from two or more steel sections connected by transverse batten plates at regular intervals, creating an integral built-up column with high transverse rigidity. |
| Key Characteristics |
• Lightweight with high material efficiency. • Excellent global buckling resistance. • Suitable for slender columns carrying heavy axial loads. • More complex fabrication due to numerous lacing members and welds. |
• Higher transverse stiffness and simpler structural configuration.• Easier fabrication, welding and inspection. • Requires more steel for connecting plates compared with laced columns. • Well suited for conventional industrial structures. |
| Typical Applications | Transmission towers, power plants, substations, mining structures, tall industrial buildings, bridge towers, and long-span steel structures. | Industrial workshops, warehouses, crane-supporting columns, equipment platforms, pipe racks, and medium-rise steel buildings. |
Key Advantages of Lattice Columns
Markedly improved flexural & lateral stiffness: With identical cross-sectional area and steel consumption, lattice columns deliver over 2 to 3 times higher moment of inertia and flexural capacity compared with solid-web members, which greatly reduces lateral deformation under compressive loads.
High-strength & lightweight performance: Hollow cross-sections assembled from angle sections or channel sections via lacing bars or batten plates can reduce structural self-weight by approximately 30%~50% compared with solid steel columns, lowering the bearing capacity requirement of foundations.
High recyclability &reduced overall costs: For foundation pit and temporary engineering projects, lattice columns feature easy disassembly with a turnover recycling rate exceeding 80%. Compared with conventional concrete struts or solid steel columns, they cut comprehensive construction costs by 20%~40%.
Unobstructed space & convenient construction: Hollow lattice systems create minimal visual obstruction and unimpeded working surfaces, facilitating the passage of large construction equipment. Additionally, individual members feature light self-weight, boosting the efficiency of on-site assembly and hoisting by approximately 40% compared with monolithic solid-web structures.

How to Install Lattice Steel Columns?
Three methods of Lattice Columns Installion
Installation of Double-Chord Lattice Columns for Heavy Industrial Workshops
The length normally falls between 15 and 25 meters, so segmental splitting is not required. The components can be delivered intact to the construction site by 17-meter flatbed trucks for integral hoisting. Hoisting shall be carried out with one large crane and one small crane operating in coordination, which is defined as the single-main-crane assisted delivery hoisting method.
Installation of Lattice Columns for Temporary Support
These steel components are prefabricated modular units (available in standard lengths of 1 m, 2 m, 3 m and so on, similar to tower crane mast modules). Bolted connection plates are fitted on the top and bottom of each unit module. After hoisting each lattice column into position, all modular sections are fastened together via bolts.
Installation of Multi‑Chord Lattice Steel Columns for Large‑Scale Public Buildings
These lattice steel columns feature large cross‑section dimensions and great height. They can only be fabricated in the factory, transported to site in separate segments and erected by segmental hoisting.
Process of Lattice Columns Installion
| Step | Description |
|---|---|
| 1. Site Preparation | Verify the foundation dimensions, anchor bolt positions, concrete strength, and installation equipment before lifting the columns. |
| 2. Column Lifting | Lift the lattice steel column using designated lifting points and certified lifting equipment to prevent distortion or local damage. |
| 3. Positioning and Temporary Fixing | Position the column accurately on the foundation, align it with the anchor bolts, and secure it temporarily with braces. |
| 4. Alignment and Leveling | Check the column's verticality and elevation using surveying instruments, making adjustments with shims if required. |
| 5. Permanent Connection | Complete bolted or welded connections according to the approved structural drawings and project specifications. |
| 6. Final Inspection | Inspect bolt tightening, weld quality, dimensional tolerances, and overall structural alignment before proceeding with the remaining steel framework. |
Note: The installation procedure may vary depending on structural design, local building codes, project conditions, and applicable standards. Professional engineering supervision is recommended for all steel structure erection work.
How to Choose the Right Lattice Steel Columns for Your Project?
Key Considerations When Select Lattice Steel Column
When selecting the right lattice steel column, engineers and project owners should evaluate the project's structural requirements, construction conditions, and overall cost. The following four factors are the most important considerations during the design and selection process.
Structural Requirements
Consider the design loads, column height, span, and required stability. Projects subjected to high axial loads or requiring greater buckling resistance generally benefit from Laced Steel Columns, while conventional industrial buildings may be better suited to Battened Steel Columns.
Construction Requirements
Consider fabrication complexity, transportation limitations, lifting methods, and on-site installation conditions.Battened Steel Columns are generally preferred for projects prioritizing simpler fabrication, faster installation, and easier maintenance, while Laced Steel Columns are suitable when structural performance is the primary concern.
Environmental & Durability Requirements
Assess the operating environment, including corrosion exposure, humidity, wind loads, seismic conditions, and maintenance requirementsaced Steel Columns are often preferred for tall structures exposed to high wind loads, while Battened Steel Columns are suitable for general industrial environments with convenient maintenance access.
Project Budget
Balance material consumption, fabrication costs, transportation, installation, and long-term maintenance expenses.Battened Steel Columns are typically more economical for standard industrial projects due to their simpler fabrication, whereas Laced Steel Columns provide better value for large-span or high-performance structures where weight reduction and structural efficiency are critical

FAQ:
What advantages do lattice columns provide over solid steel columns?
When compared to solid parts of the same size, these designed structures are 30 to 40 percent lighter while still holding the same amount of weight. The lighter weight cuts down on the need for foundations, lowers the cost of shipping, and makes the building more resistant to earthquakes. Open-web designs reduce wind loads and make it easier to view the inside for rust tracking.
Can lattice column designs accommodate custom architectural requirements?
According to modular design principles, sizes, connections, and load requirements can be changed in a lot of ways. Engineers work directly with architects and structural consultants to come up with solutions that meet both the needs of the architect's aesthetic vision and the needs of the structure's performance. Because they can do custom manufacturing, they can work with different project shapes and keep costs low by using standard production methods.
Is weld inspection required for lattice columns?
Yes. Welded zones are prone to residual stress and deformation caused by thermal expansion and contraction. Ultrasonic testing or radiographic non‑destructive testing shall be performed to detect internal cracks and defects.
What are the requirements for batten spacing of lattice columns?
It shall comply with calculation criteria for chord stability and overall slenderness ratio, to avoid premature chord buckling ahead of global member buckling due to excessively large batten spacing.
