Dragon Stage
Not every event structure needs triangle or square truss.
When the buyer mainly needs a relatively flat framework for:
lighting, curtains, signage, exhibitions or decorative displays,
a flat truss, also commonly called ladder truss, can provide a simpler and more compact solution.
This 290mm Aluminum Flat Ladder Truss uses two main longitudinal tubes connected by diagonal bracing, creating a much slimmer profile than triangle or square truss.
The structure uses:
50 × 2mm main tubes
with:
20 × 2mm braces
and a spigot / conical connection system for joining compatible sections.
DragonEvent will offer standard lengths from:
0.5m to 2.5m
with additional custom lengths available for specific layouts and replacement requirements.
For other straight truss formats, browse Straight Truss.
Nominal truss depth:
Approx. 290mm / 11.4in
Unlike triangle truss with three chords or square truss with four chords, flat truss uses a two-chord ladder-style geometry.
This creates a slimmer structure that can be useful where the buyer wants:
less visual bulk + easier storage + straightforward mounting framework.
Main tube specification:
50mm outside diameter
2mm wall thickness
approximately:
1.97in OD × 0.079in wall
The 50mm tube format also allows buyers to select compatible clamps from the common 48–51mm clamp range, provided the actual mounting application is appropriate.
Diagonal brace specification:
20mm outside diameter
2mm wall thickness
The braces connect the two main chords and form the ladder-truss structure.
Material:
6082-T6 aluminum alloy
This keeps the truss suitable for portable event applications where equipment may be repeatedly transported, assembled and stored.
Straight sections connect through a:
Spigot / Conical Connection System
rather than a bolt-ended plate.
Compatible connection hardware typically uses:
conical couplers + pins + safety clips
according to the selected system and package.
The standard version uses a:
Natural / Milled Aluminum Finish
which works well for:
exhibitions;
studios;
retail displays;
markets;
restaurants;
visible event structures.
The exposed aluminum can remain part of the overall installation appearance rather than needing to be hidden.
DragonEvent can offer priced SKU options such as:
0.5m / 1.64ft
1.0m / 3.28ft
1.5m / 4.92ft
2.0m / 6.56ft
2.5m / 8.20ft
Custom length can be useful when the buyer needs to:
match a fixed wall or booth dimension;
replace an existing section;
build a recurring studio grid;
reduce unnecessary connections;
fit transport or storage limitations.
The required finished length should be confirmed before production.

Flat truss is useful where a studio needs a relatively slim framework for compatible lighting fixtures.
Compared with a larger square truss, the flatter profile can occupy less vertical space and create a cleaner overhead arrangement.
A ladder-style truss can be useful as part of suitable curtain or drape-support arrangements.
Its flat geometry makes it particularly relevant where the main requirement is a straight horizontal framework rather than a large three-dimensional truss system.
Flat truss can form part of:
exhibition frames;
signage supports;
product displays;
booth decoration;
promotional structures.
For many exhibition applications, the slim aluminum structure is less visually dominant than box truss.
The natural aluminum appearance can work well in:
retail stores;
shopping malls;
restaurants;
food trucks;
markets;
showrooms.
In these environments, the truss itself can become part of the visual design.
For suitable lightweight event-lighting setups, flat truss can provide a modular mounting framework.
Lighting equipment still requires compatible clamps and appropriate mounting hardware.
Browse Truss & Rigging Accessories for related clamps and connection components.
Choose flat / ladder truss when your priority is:
slim profile + straight mounting framework + display / curtain / studio use.
Choose triangle truss when you need a three-chord geometry.
Choose square truss when you need a four-chord structure or equipment mounting from several sides.
Nominal depth:
290mm / approx. 11.4in
If you already own truss, measure the actual profile rather than relying only on the product name.
If you are adding this product to an existing system, confirm:
main tube size + connector diameter + cone dimensions + pin dimensions.
Two 290mm flat trusses are not automatically compatible.
Suppose you need a:
4m display frame.
Possible options include:
2m + 2m
or:
1m + 1.5m + 1.5m
The first reduces connection points.
The second creates more reusable lengths for future installations.
For rental companies and mobile installers:
shorter sections = easier transport and more combinations
while:
longer sections = fewer connections and faster assembly.
Choose according to how the truss will actually be used.
For extending an existing compatible flat-truss system, the minimum package may be:
**1 × Flat Truss Section
Compatible Connection Hardware**
For a new display or lighting frame, the buyer may also need:
matching corners or junctions + bases/supports + clamps + connection hardware.
Do not automatically buy a large complete truss package if a few straight sections solve the actual requirement.
The main requirement is:
studio grid + curtain support + exhibition display + signage + decorative framework
and a slim profile is useful.
You want:
three-dimensional triangular geometry + stage lighting use + a more substantial event structure.
These should remain two separate product families rather than being selected only by price.
you prioritize:
compact profile + easier storage + display and lightweight applications.
you need:
four-chord geometry + mounting from multiple faces + larger event framework.
For buyers comparing other straight-truss options, see Straight Truss.
Lighting is only one application.
Flat truss is also useful for:
curtains, studios, displays, signage and decorative commercial structures.
Flat truss has:
2 main chords.
Triangle truss has:
3 main chords.
They are different systems.
The connection still needs to match.
Check:
tube + coupler + pin + connector geometry
before expanding an existing system.
The physical tube diameter is only one factor.
Fixture weight, clamp design and the complete mounting arrangement also matter.
A 2.5m section may be convenient for one installation but less flexible for future rental layouts.
Mixed lengths are often more useful.
Custom production is useful for recurring fixed layouts.
For general rental stock, standard modular lengths usually provide better flexibility.
Do not use structural numbers from another truss brand or test report as the rating for this product.
The actual product configuration needs its own verified technical data.

Possibly, but compatibility must be confirmed from the actual connector and tube dimensions.
Yes, suitable curtain and theatre applications are one of the natural uses for flat truss.
Yes, for suitable lighting applications where the fixture, clamp and complete truss arrangement are appropriate.
It should not automatically be treated as a substitute for a larger structural truss system.
Large roofs, towers, long spans, large LED walls or significant suspended loads require an appropriate complete truss solution and project-specific evaluation.
