Custom High-Strength Steel Trusses for Construction

Steel trusses consist of interconnected straight members forming triangular units, including top chords, bottom chords, web members, and gusset plate connections. This configuration ensures that forces are primarily carried as axial tension or compression, maximizing structural efficiency.

Typical applications include:

• Industrial factory roofs
• Warehouse long-span structures
• Stadiums and arenas
• Airport terminals
• Bridges and elevated walkways
• Heavy industrial facilities

Custom steel trusses are high-strength and lightweight structural steel components, widely adopted for stadiums, exhibition halls, bridges, airports and industrial buildings. 

GNEE supplies custom roof trusses, space trusses, bridge trusses, crane trusses and stage trusses fabricated from carbon steel, stainless steel and aluminum alloy.Featuring optimized structural design, easy field installation and versatile surface finishes including hot-dip galvanizing and paint coating, we offer a full range of conventional steel truss products, delivering durable and cost-effective solutions for your large-span construction projects

 

Triangular Roof Truss

Description: As one of the most traditional and stable forms of roof truss structures, it consists of a series of interconnected triangles.

 

Applications:Industrial buildings, warehouses, workshops, and exhibition halls.

 

Features:

High stability with a simple geometric structure;

Easy to fabricate and cost-effective;

Lightweight yet capable of bearing large roof loads

Tubular Space Truss

Description:A tubular space truss is a three-dimensional truss system composed of tubular members. 

 

Applications:Stadiums, airport terminals, exhibition halls, large railway stations, and plaza roofs.

 

Features:
Spatial load-bearing and high stability;
Lightweight, high strength, and large spans;

Various shapes allow for the formation of various curved surfaces

Trapezoidal Truss

Description:This type of truss features top and bottom chords arranged in a trapezoidal configuration. It provides a moderate roof slope while optimizing the overall structural height.

 

Applications:Sports arenas, exhibition centers, factories, and auditoriums.

 

Features:

Ideal for medium-span roof structures;

Compact and aesthetic appearance;

Reduces roof height for improved space efficiency

Bridge Truss

Description:Two main types : pedestrian bridge trusses, suitable for footbridges or light-duty access ways; and high-speed railway bridge trusses, engineered for railway bridge construction.

 

Applications:Footbridges, elevated walkways, factory corridors, and small river-crossing bridges.

 

Features:

Aesthetic design that complements building facades;

Lightweight yet high rigidity;

Fast construction and easy on-site assembly

 

 

 

Tower and Mast Truss

Description:These are tall trussed or tubular structures designed to support antennas, lighting, power transmission, or monitoring equipment. Towers are self-supporting structures, while masts are typically stabilized with guy wires.

 

Applications:Communication towers, transmission towers, light poles, wind turbine support towers, and monitoring towers.

 

Features:

Modular manufacturing and transportation;

Low maintenance requirements and long service life;

Tall, stable structure with excellent wind and seismic resistance

 

Our steel truss production is based on industrial-grade fabrication systems integrating automation and precision engineering.

Core Raw Material Components

GNEE is an experienced supplier of custom steel truss solutions. Our factory manufactures a full range of roof trusses, floor trusses, truss girders, and other structural frame trusses. Steel trusses are produced and supplied in the following configurations, based on different steel grades and material types.

Tubular Truss Components

Components of tubular trusses are only subjected to axial tension or compression, with stress evenly distributed across the cross-section.

Angle Steel Truss Components

Angle steel components feature lightweight cross-sections and cost advantages. 

H-Shape Truss Components

H-section truss components boast a larger section modulus, lighter weight and reduced material consumption.

Box Truss Components

 

Box truss components feature high overall rigidity and light weight.

Quality Control

GNEE's steel truss quality control system includes strict dimensional inspection to ensure all members and assemblies meet design tolerances, ultrasonic testing (UT) for critical welds to detect internal defects, load verification simulation to evaluate structural performance under dead load, live load, wind load, snow load, and crane load conditions, as well as coating inspection to verify surface protection quality including coating thickness, adhesion, and corrosion resistance, ensuring full compliance with engineering standards and project requirements.

GNEE implements rigorous precision manufacturing and quality control for tubular trusses throughout the whole process, from raw materials to finished products.

 

1.Raw Material Preparation:We start with finished steel pipes, the basic raw material for manufacturing tubular trusses.

 

2.Pipe Cutting and Forming:Finished steel pipes are cut to required lengths and angles strictly in line with design drawings.

 

3.Pipe Hot Bending:The cut steel pipes are heated and bent by hot bending machines to create complex curved components for tubular trusses, namely hot-bent pipe fittings.

 

4.Assembly and Welding:Pipe components after cutting and hot bending are assembled as per design. All parts are firmly joined by structural welding. Structural stiffeners are welded at key joints to boost overall structural strength.

 

5.Quality Inspection:After welding, we conduct strict inspection on weld seams via non-destructive testing including ultrasonic testing. This guarantees weld joints are free of internal defects and fully meet safety standards.

Our steel trusses are securely packaged using steel frames, protective wrapping, and labeled modular bundling to ensure safe transport. Depending on project requirements, they are delivered as prefabricated modules, segmented units, or flat-pack export packages suitable for container or bulk shipment, ensuring efficient loading, reduced damage risk, and easy on-site installation.

FAQ:

How are long-span trusses transported and assembled on site?

Trusses are engineered to ship as segmented or flat-pack modules sized for containers or low-bed trailers, then assembled by bolting and field welding at site with a small lifting plan and curated erection drawing.

How do I choose between welded and bolted truss connections?

Welded (AWS D1.1, UT-tested) gives smooth, continuous joints that suit permanent heavy structures; high-strength bolted connections (8.8/10.9) are cleaner for on-site assembly, disassembly and future relocation. We often use a hybrid - shop welding with bolted field splices.

What fire and corrosion protection is recommended over the service life?

For corrosion, choose hot-dip galvanizing or Sa2.5 blasting plus a matching paint system by environment class. For fire, structural steel can be protected with an approved intumescent coating or passive fire-proof cladding to reach the fire rating your code requires.

Do you design and detail the truss, or do you work from my drawings?

Both. If you have structural drawings we fabricate directly to them; if you only have a layout, span, loads and location, our engineering team designs, details and optimizes the truss, then issues a certified fabrication/erection drawing for approval before production.

What information do I need to send to get a truss quote?

A span, bay spacing or building plan, design loads (roof, snow, wind, crane), target grade and connection (welded / bolted), surface finish (galvanized / blasted-and-painted), and either a drawing or the clear span and height you need. With that we confirm geometry and quote within 24 hours.
