Steel trusses use a series of interconnected chords and web members to transfer structural loads efficiently. This allows the structure to achieve large spans while controlling overall steel consumption and structural weight.

Our truss components can be produced according to customer drawings, engineering calculations, project specifications, and installation requirements. From individual roof trusses to complete structural packages, we support customized fabrication for international construction projects.

Product Features

Excellent Structural Efficiency

The triangulated configuration provides efficient load transfer and helps improve overall structural stability.

Suitable for Wide Clear Spans

Steel trusses can cover large spaces with fewer internal columns, helping create open and flexible building layouts.

High Strength-to-Weight Ratio

Optimized member arrangements provide strong load-bearing performance without unnecessarily increasing structural weight.

Factory Prefabrication

Most cutting, drilling, welding, fitting, and inspection work can be completed in the factory, reducing site fabrication requirements.

Flexible Connection Design

Connections can be designed for welding, bolting, or a combination of both according to erection and transportation requirements.

Multiple Corrosion Protection Options

Painting, galvanizing, primer systems, and customized protective coatings are available for different service environments.

FAQ

1. What information is required for a steel truss quotation?

For an accurate quotation, please provide structural drawings, truss dimensions, steel grade, quantity, surface treatment requirements, connection details, and project location.

2. Can the truss size be customized?

Yes. Span, height, section size, member arrangement, and connection design can be customized according to project requirements.

3. Can large trusses be divided into several sections for shipping?

Yes. Large trusses can be fabricated in transportable sections and connected on site using bolted or engineered connections.

4. Do you supply galvanized steel trusses?

Yes. Hot-dip galvanizing and other corrosion protection systems are available depending on project conditions.

5. Can you fabricate trusses from rectangular or circular hollow sections?

Yes. RHS, SHS, CHS, H-section, angle steel, channel steel, and fabricated steel sections can be used depending on the design.
