1. 50 × 2mm Aluminum Main Tube

Main tube specification:

Outside Diameter: 50 mm / 1.97 in

Wall Thickness: 2 mm / 0.079 in

This gives the product a much slimmer profile than conventional box truss while retaining the modular connection logic of professional event truss.

The reference product family also uses T6061 aluminum alloy for this type of single-tube truss.

2. Custom Lengths from 0.2m

DragonEvent can supply lengths starting from:

0.2m / 7.9 in

and customize longer sections according to the buyer's required layout.

This is especially useful when standard 0.5m / 1m / 2m sections do not fit the actual installation.

Typical custom requests may include:

• 0.2m

• 0.3m

• 0.5m

• 0.75m

• 1.0m

• 1.5m

• 2.0m

• other project-specific lengths

These examples are purchasing options, not fixed limits.

3. Silver and Black Options

Silver / Natural Aluminum

A good fit when the truss itself is intended to remain visually visible.

Common uses include:

• exhibitions;

• trade shows;

• retail displays;

• decorative event structures;

• industrial-style interiors.

Black

Black truss is useful when the buyer wants the support tube to visually recede into:

• black stages;

• clubs;

• theatres;

• DJ setups;

• lighting installations;

• dark exhibition backgrounds.

The reference F31 family is also sold in both silver and black versions, confirming these as established finish choices for this type of one-point truss.

4. Conical Connector System

The truss uses a modular conical connection system.

A typical connection requires:

Truss Section + Conical Coupler + Pin + Safety Clip

This allows multiple compatible straight sections to be combined.

However, similar-looking conical systems are not automatically interchangeable.

5. Very Small Transport Volume

One of the major advantages of a single-tube truss is its compact profile.

Compared with triangle or square truss, it occupies much less transport and storage space.

This can be particularly useful for:

• exhibition contractors;

• mobile event companies;

• retail display installers;

• rental businesses;

• buyers shipping smaller quantities.

The reference F31 system is similarly positioned around low transport volume and lightweight construction.

Important Load Note

Load capacity is not one fixed number for every length.

It changes according to:

Span + Length + Coupling Position + Load Type + Support Arrangement + Actual Product Configuration

The reference product's published engineering table clearly shows different allowable loads depending on span and whether a coupling is present.

For that reason, DragonEvent should not copy one load number across all custom lengths.

Exhibition Display Structures

Single-tube truss works well when the structure itself needs to remain visually light.

It may be used for compatible:

• banners;

• signage;

• product displays;

• decorative rails;

• exhibition booth elements.

The smaller tube profile can look cleaner than a full square truss when heavy visual structure is unnecessary.

Retail & Shop Displays

A silver single-tube truss can create an industrial display style while remaining relatively compact.

Black versions can blend into darker retail or showroom environments.

Event Lighting Support

The 50mm tube can accept compatible clamps designed for approximately 48–51mm tubing.

This makes it useful for suitable lightweight lighting and accessory mounting applications.

For compatible mounting hardware, browse Truss & Rigging Accessories. DragonEvent currently groups clamps, couplers and other truss-mounting hardware there. DragonEvent

DJ & Mobile Event Setup

For mobile DJ applications, a single-tube section may be useful when the buyer needs:

• a compact lighting bar;

• decorative support;

• small display frame;

• simple modular tube structure.

If the load or span becomes substantial, move to a more appropriate multi-chord truss rather than simply increasing the single-tube length.

Decorative Structures

The product can also be useful where the visual goal is:

minimal structure + exposed aluminum tube

rather than the more industrial appearance of box truss.

How to Choose

Step 1 — Choose the Finish

Choose:

Silver

when the aluminum structure can remain visually exposed.

Choose:

Black

when the truss should visually blend into a dark stage or lighting environment.

Step 2 — Choose the Length

Start from the actual installation dimension.

DragonEvent can customize sections from:

0.2m upward

For example, if your target width is 2.4m, you might choose:

1.2m + 1.2m

or another combination depending on transport and reuse requirements.

For rental inventory, several shorter sections may provide more flexibility than one long section.

Step 3 — Decide Whether You Need One Section or a Modular Combination

One long section gives:

fewer connections

while multiple short sections provide:

easier transport + more reusable combinations

For rental companies, modularity is often more valuable than minimizing the number of joints.

Step 4 — Confirm Connector Compatibility

If adding this product to an existing truss system, provide:

Tube Diameter
Connector Photo
Conical Coupler Dimensions
Pin Diameter
Existing Brand / Model if known

before ordering.

Do not assume all 50mm one-point trusses connect together.

Step 5 — Determine the Actual Load Requirement

Tell us what will be attached:

banner?

LED light?

PAR light?

decorative item?

display panel?

The correct length and system should be selected according to the actual use.

Minimum Practical Package

For one standalone straight section:

1 × Single Tube Truss

may be enough if it is being used as an individual component within an existing compatible system.

For a modular extension:

**2 or More Truss Sections

• Matching Conical Couplers

• Pins

• Safety Clips**

are required.

If equipment will be mounted:

+ Compatible 48–51mm Clamp

may also be needed.

Single Tube Truss vs Square Truss

These products should not be selected only according to appearance.

Choose Single Tube Truss When:

• the structure should remain visually minimal;

• transport volume matters;

• the setup is relatively simple;

• custom short lengths are useful;

• loads and spans are appropriate for this system.

Choose Square or Triangle Truss When:

• longer spans are needed;

• more lighting is being supported;

• torsional stability becomes important;

• the structure itself forms a larger event framework.

The smallest practical product is usually the better purchase—but only when it genuinely fits the load and layout.

Buying Mistakes to Avoid

1. Assuming a 50mm Tube Is the Same as a 50mm Clamp

A clamp specified for 48–51mm tubing may fit the physical tube diameter, but that does not automatically verify the complete mounting application.

Check the clamp and equipment separately.

2. Copying Load Ratings from Another Brand

Two products may both use:

50 × 2mm aluminum tubing

but that does not prove identical structural capacity.

Material, connector, manufacturing, span and support conditions all matter.

3. Choosing One Very Long Section Only to Avoid Connectors

Long sections can become:

• harder to ship;

• harder to store;

• less flexible for rental inventory.

Sometimes:

2 × 1m

is a more practical purchase than:

1 × 2m

depending on future use.

4. Assuming Every Conical Connector Is Compatible

Conical systems can differ in:

• connector diameter;

• taper;

• pin size;

• hole position;

• locking clip.

Compatibility must be checked.

5. Using Single-Tube Truss Where Box Truss Is Actually Needed

A clean appearance does not make a single-tube system suitable for every structural task.

If the installation involves:

• long spans;

• significant suspended loads;

• large LED screens;

• speakers;

• outdoor wind-exposed structures;

move to the appropriate truss or project-level structural solution instead.

Truss Buying Guide

If the buyer is unsure whether single-tube, triangle or square truss is more appropriate:

Truss Buying Guide for Events: What Should You Buy First?

The guide follows the decision path from event type and application to the minimum practical truss system. DragonEvent

What is a single-tube truss?

It is a one-point truss built around one primary aluminum tube rather than the three or four main chords used in triangle or square truss.

What is the tube diameter?

The main tube is:

50mm / 1.97in outside diameter

with a:

2mm / 0.079in wall thickness.

What lengths are available?

DragonEvent can customize lengths starting from:

0.2m / 0.66ft

with longer lengths produced according to the required configuration.

Is black available?

Yes.

The product can be supplied in:

Silver / Natural Aluminum

or

Black.

Can I order several different lengths?

Yes.

For example, a buyer can combine shorter and longer sections to create a more flexible modular inventory.

Does it include connectors?

The exact package should specify whether the conical coupler, pins and clips are included.

Confirm the required connection package when ordering.

Can I connect it to Global Truss F31?

Possibly, but compatibility should not be assumed from the 50 × 2mm tube size alone.

Connector geometry and pin dimensions must also match.

Can I hang lights from it?

Compatible lighting may be mounted when the actual load, span, clamp and installation arrangement are appropriate.

Use a suitable clamp matched to the 50mm tube.

Can it be used horizontally?

Yes, in suitable configurations, but allowable span and load depend on the actual setup.

The reference engineering data for similar F31 truss shows that capacity changes substantially as span increases.

Can I use the reference load table on this product?

No.

The reference table is useful for understanding how span and coupling position affect capacity, but it belongs to that manufacturer's specific system.

Your DragonEvent product should use its own verified load data if numerical structural ratings are published.
