Aluminum Square Truss 290x290mm 50x2mm for Event Backdrop

290 × 290 mm Square Configuration

The four-chord square configuration provides structural rigidity in multiple directions while maintaining a relatively compact cross-section.

The 290 mm format is widely used for small and medium event structures because it is easier to transport and handle than larger structural truss while still providing a practical framework for many professional event applications.

1m / 3.28ft Modular Length and other custom length

Each straight section is 1 meter (3.28 ft) long and other custom long.

The short modular length is particularly useful when:

adjusting the overall dimensions of a truss structure;

building compact DJ or lighting structures;

constructing exhibition and backdrop frames;

combining several sections into longer spans;

creating structures where transportation and storage space matter.

Other truss lengths can also be combined within the same compatible system to create the required overall dimensions.

Spigot Connection System

The truss uses a conical spigot connection system, allowing sections to be assembled and dismantled efficiently.

Compared with repeatedly bolting large connection plates together, the spigot system is particularly suitable for event applications that require frequent installation, dismantling and reconfiguration.

For a broader explanation of the differences between common truss joints, see Understanding Spigot, Bolt and Plate End Connections in Truss Systems.

Important: Load capacity should not be determined from the dimensions of one truss segment alone. Actual structural capacity depends on span, support conditions, connection configuration, load position, number of suspended fixtures and the overall system design.

This distinction is important because a 1 m truss section being physically capable of carrying a certain load does not mean a multi-meter assembled span has the same allowable load. For larger systems, the complete structural configuration must be considered. See Load Analysis for Modular Stage Systems for the general engineering logic behind system-level load assessment.

Event Lighting Structures

The 290 mm square truss can be used to support lighting fixtures and related event equipment in appropriately designed configurations.

Typical applications include:

DJ lighting rigs · small stage lighting · mobile event production · nightclub installations · indoor event lighting

For customers building complete lighting structures rather than purchasing an individual segment, our Event Truss solutions provide additional system configurations.

DJ Truss Structures

The compact dimensions make this truss suitable for DJ applications where equipment must be transported, assembled and dismantled frequently.

It can be incorporated into:

DJ booths, lighting frames, overhead lighting structures, decorative truss structures and mobile event rigs.

Event Backdrop Frames

This is one of the important applications of the product, but not its only use.

Multiple straight sections can be combined with compatible corners, bases and accessories to form rectangular backdrop structures for:

weddings · corporate events · photo areas · brand activations · stage backgrounds · entrance displays

Exhibition & Trade Show Structures

Square truss is also commonly used for temporary exhibition structures because modular components can be reconfigured for different booth dimensions.

For more complex exhibition applications, customers can explore our Exhibition Display Truss configurations.

Why Use a 1m Truss Section?

A 1-meter truss should not be viewed simply as a “small truss.”

Its real value is modular dimension control.

For example, if a structure requires a particular overall width or height, different standard straight-section lengths can be combined to approach the required geometry without manufacturing every structure as a completely new product.

This modular logic is fundamental to professional stage and truss systems. Our article on Modular System Logic for Stage, Truss & Scaffold explains how standardized components can be combined into different temporary structures.

Aluminum Construction for Event Use

Aluminum is widely used in temporary event truss because it provides an effective balance between structural performance and handling weight.

This becomes particularly important for rental companies and event contractors because truss components may be:

transported → unloaded → assembled → dismantled → loaded again

many times during their service life.

Lower component weight can therefore influence not only transportation but also installation efficiency and manual handling.

Building a Complete Truss System

A straight 1m section is only one component within a modular truss system.

Depending on the intended structure, a complete configuration may also require:

straight truss sections + corners + connectors + base plates + clamps + support components + lifting or tower components

The required components depend on whether the final structure is a backdrop, lighting goalpost, exhibition booth, suspended lighting structure or another event configuration.

DragonStage supplies both individual Standard Spigot Truss components and complete customized event truss systems.

If you provide the required length, width, height, application and equipment to be supported, we can help determine a suitable component configuration.

How to Choose the Correct Truss

For a simple decorative backdrop, the primary considerations may be overall dimensions, stability and accessory compatibility.

For lighting or equipment-support applications, however, selection should additionally consider:

span length, total equipment weight, load positions, support method, connection system and environmental conditions.

A truss should therefore not be selected solely because its outside dimensions match another product.

For larger or structurally demanding projects, the complete system should be evaluated rather than treating each truss segment independently.

FAQ

1. What size is this square truss?

The truss has an outside cross-section of approximately 290 × 290 mm (11.42 × 11.42 in). This particular section is 1 m / 3.28 ft / 39.37 in and other custom length.

2. Is this truss only used for event backdrops?

No. Event backdrops are only one application. The same 290 mm square truss format can also be used for lighting structures, DJ setups, exhibition displays and other temporary event structures when the overall configuration is appropriate.

3. Can I connect several 1m truss sections together?

Yes. The modular spigot connection system allows compatible sections to be connected to create longer truss runs. Different standard lengths can also be combined when they use the same compatible connection geometry.

4. How much weight can this 290mm square truss support?

There is no single safe load figure that should be applied to every assembled structure. Allowable loading depends on span, support points, load distribution, connection configuration and the complete structural design. For significant suspended loads or complex structures, project-specific engineering verification should be used.

5. Can DragonStage provide a complete truss structure instead of individual sections?

Yes. DragonStage manufactures individual aluminum truss components as well as complete event structures. Provide the required length × width × height, intended application, installation environment and the equipment that needs to be supported, and we can develop an appropriate configuration.
