Product Information

Dimensions are nominal component and system designations from the supplied BOM. Final outside dimensions, roof height, support positions, and side-wing projection should be confirmed from the assembly drawing.

Product Description

The DragonStage 15×10×8m Curved Roof Truss System is designed for temporary concert and festival stages requiring a covered overhead truss framework with additional side-wing structures.

The main structural configuration combines four support towers with horizontal frame trusses, curved roof members, and transverse truss components.

Two additional towers are positioned outside the main roof configuration and connected through side-wing beams.

The resulting system is made up of three functional component groups:

1. Main 15×10m truss frame and support towers

2. Curved roof truss and PVC canopy

3. Two additional side-wing truss assemblies

The modular spigot connection system allows the individual truss sections and tower components to be separated for transport, storage, and repeated event use.

Main 15×10m Truss Frame

The main frame uses CS389×389mm aluminum square spigot truss, with 50mm main tubes and 3mm wall thickness.

The published component list includes:

The 3m front sections provide the listed nominal lengths for two 15m beams.

For the two 10m side beams, the listed combination of 3m and 1m sections corresponds to the nominal beam lengths.

This modular arrangement allows the main frame to be assembled from standard truss sections rather than one permanently fabricated structure.

Four Main Support Towers

The main roof frame is supported by four tower assemblies.

Each tower uses CS289×289mm aluminum spigot truss, together with lifting and support components.

Main Tower Truss Components

The sleeve blocks, top sections, hoists, hinge sections, bases, and outriggers form the listed tower-system component package.

The 2-ton figure identifies the nominal specification of the BA05 hoist. It does not represent the allowable roof load or the capacity of the complete tower assembly.

For additional tower components, see Typical Tower Elements.

Curved Roof Truss Structure

The upper roof uses a curved arrangement rather than a flat rectangular roof.

The curved roof structure includes arch trusses, ladder trusses, a transverse top beam, and associated connection components.

The supplied BOM identifies:

The 17m designations are retained from the original BOM.

The listed 3m and 2m sections do not, by themselves, total 17m for each arch or ladder truss run. The missing 0.5m quantities and final assembled lengths should be confirmed against the manufacturing drawing before the component list is finalized.

For other curved-roof configurations, see Typical Curve Roof Truss Systems.

Roof Connectors, Clamps and PVC Canopy

The curved roof includes additional connection components and a roof covering.

The original BOM also contains a value of 304.76 alongside the PVC canopy specification, but its unit is not identified. This value should be verified before being published as a roof area or material quantity.

The supplied drawing shows the roof-truss framework without a fully rendered fabric covering, while the BOM lists a PVC canopy.

The canopy's exact dimensions, material weight, fire-performance specification, fastening arrangement, and weather-resistance characteristics require separate confirmation.

Twin 2m Side Wing Truss Structures

One of the main differences between this product and a conventional four-tower curved roof system is the inclusion of two additional wing structures.

Each side wing includes an extension beam and a separate support tower.

The wing beams use CS389×389mm square spigot truss, while the wing towers use CS289×289mm truss.

Side Wing Components

The additional wing towers provide separate support positions outside the main roof structure.

They may be considered when planning production-side equipment arrangements, including suitably designed side-display or sound-support layouts.

However, the intended equipment, attachment points, load capacities, and final functions of the wings must be confirmed before installation.

Six-Tower Ground Support Arrangement

The complete roof and wing configuration contains six tower assemblies:

• Four towers for the main curved roof structure

• Two additional towers for the side wings

According to the combined BOM, the tower-system components include:

This arrangement differs from a simple four-tower roof system because the wing assemblies have their own tower and support components.

The complete lifting procedure, hoist loading, tower stability, support interfaces, and bracing arrangement must be determined from the final technical documentation.

Modular Spigot Connection System

The current configuration uses spigot-connected aluminum truss sections.

The accessory list includes:

Conical Couplers, Pins and Safety Clips — Complete Set

Spigot connections allow matching truss sections to be joined using the corresponding connector components.

This makes the truss inventory modular and provides a practical way to assemble a structure from repeatable section lengths.

Customers who already own spigot truss should check the section dimensions and connection geometry before assuming that their existing components are compatible.

Matching Modular Concert Stage

The supplied product illustration also shows a raised modular concert stage beneath the curved roof.

The illustrated stage includes:

• Black stage deck surface

• Modular support structure

• Perimeter guardrails along selected edges

• Two stair-access positions

However, the supplied BOM covers the roof and wing truss components and does not identify the complete stage deck, support, guardrail, or stair quantities.

Therefore, the stage should be treated as a matching configuration to be quoted separately unless a combined stage-and-roof package is confirmed.

For matching platforms, explore Stage Platform Systems.

Designed for Concert and Festival Applications

This roof-truss configuration may be suitable for:

• Concert productions

• Music festivals

• Outdoor entertainment events

• Touring stage productions

• Cultural performances

• Public entertainment stages

• Large temporary event setups

• Production stages requiring side-wing structures

The curved roof profile creates a different visual appearance from conventional flat or pitched roof structures.

At the same time, the modular components allow the system to be manufactured, packed, transported, and assembled as separate sections.

Actual suitability for a specific event depends on the full engineering configuration and site conditions.

Why Choose a Curved Roof with Side Wings?

A conventional four-tower roof system provides the main covered stage area.

Adding two separate side-wing towers changes the layout by creating additional structural positions outside the central roof.

This can be useful for productions that need to plan the main stage roof and side equipment arrangements together.

The practical value is not simply that the structure is larger. The two wing sections form distinct parts of the overall event-production configuration.

For customers comparing different roof shapes, tower layouts, and side extensions, the choice should be made according to the intended equipment and available event site.
