Product Description
The DragonStage 12x9x8m Aluminum A-Frame Roof Truss System is a complete modular roof-support structure for concerts, festivals, church events, public performances, and other temporary outdoor productions.
The main truss structure is approximately 12m wide, 9m deep, and 8m high. The primary horizontal beams use CS389×389 square truss, while the vertical towers and roof-frame components use CS289×289 aluminum truss.
The pitched roof is built from top beams, oblique beams, ladder trusses, roof connection components, clamps, and a PVC canopy. This creates a covered overhead structure suitable for event lighting, sound, and other production equipment subject to the final project configuration.
For other roof types and dimensions, see Roof Truss and Typical A-frame Roof Truss System.
Main Ground Support Structure
The main structure uses four lifting towers.
Each tower system includes:
Spigot sleeve block
Steel base
Top section
2-ton manual hoist
1m spigot hinge section
2-ton fiber sling
Long outriggers
This configuration allows the horizontal roof structure to be assembled at a lower working height and then raised along the towers as part of the installation process.
For general erection principles, see Installation Methodology for Modular Stage, Truss & Scaffold Systems.

Why Use Separate Side Wings?
One practical advantage of this configuration is that speaker or auxiliary equipment does not need to occupy the main roof beam.
Separating the wing structures gives the production team more flexibility to organize:
This can make the overall concert layout cleaner and easier to manage.
For broader live-production applications, see Concert Event.

Typical Applications
Stage Platform Note
This product page mainly defines the roof truss and wing support structure.
If a complete event stage platform is also required, DragonStage can configure a matching modular platform system according to the required width, depth, and stage height.
For available platform systems, see Stage Platform.
Important Technical Note
The product information above confirms the physical truss configuration, sizes, tower components, hoists, wings, and roof canopy.
It does not establish a universal value for:
allowable roof load
lighting load
speaker load
LED load
wind resistance
ballast requirement
anchoring requirement
safety factor
engineering approval
Those depend on the actual equipment, installation site, roof-cover condition, support arrangement, and complete structural configuration.
For this distinction, see Safety Standards & Engineering Constraints.
FAQ
What is the overall size of this truss system?
The main roof structure is approximately 12m wide × 9m deep × 8m high.
What type of roof does it use?
It uses an A-frame / pitched roof configuration with sloping roof beams and PVC canopy.
What size truss is used for the main beams?
The main horizontal beams use CS389×389 square truss with 50×3.0mm main tubes.
What size truss is used for the towers?
The main towers use CS289×289 aluminum square truss.
Does the system include lifting equipment?
Yes. The main system includes 4 manual 2-ton hoists, one for each primary tower.
Does it include speaker wings?
Yes. There are two side wing structures, approximately 2m wide each.
Can line array speakers be hung from the wings?
The wings are intended as auxiliary support positions, including possible speaker use, but the actual speaker weight and suspension arrangement must be confirmed before production.
Is a roof canopy included?
Yes. A PVC roof canopy is included in the current configuration, with color customization available.
Is the stage platform included?
The current confirmed BOM mainly describes the roof and wing truss structure. A matching stage platform can be supplied separately according to project requirements.
Can the dimensions be customized?
Yes. Width, depth, height, wing size, tower layout, and roof configuration can be customized.
What information do you need for quotation?
Please provide the required roof dimensions, event location, indoor or outdoor use, lighting equipment, speaker system, LED requirements, and whether a stage platform is needed.
Why Choose DragonStage
DragonStage supplies Roof Truss structures, Stage Platform systems, and complete concert-event combinations.
For a project like this, we recommend confirming the roof size, suspended lighting, speaker configuration, stage dimensions, site conditions, and roof-cover requirements together rather than selecting the truss only by its outside dimensions.
For quotation, please send us:
required roof width × depth × height
event location
speaker model and quantity
lighting equipment and approximate weight
LED screen requirements if any
whether the stage platform is required
preferred roof-cover color
indoor or outdoor use
We can then confirm the suitable truss and tower configuration.
