This large hybrid event structure combines a 20 × 18m steel Ringlock stage platform, a 12m-high aluminum roof truss system and two nominal 10m side-wing structures.
The stage uses 1 × 2m aluminum-framed decks with 18mm anti-slip plywood, supported by modular steel Ringlock standards, ledgers, braces and adjustable bases. The roof combines CS520 × 760mm primary aluminum truss with CS289 × 289mm secondary roof members and an electric motor-hoist system.
The stage platform, aluminum roof and Ringlock wall or wing structures are listed as separate system modules. The final quotation must clearly identify which modules, accessories, roof covering, lifting equipment and structural components are included.
For an explanation of the steel support platform, see our Ringlock steel stage system guide.
This system combines two different structural systems within one large concert-stage configuration.
The lower performance platform and supporting wall structures use modular steel Ringlock components. The primary roof beams use large CS520 × 760mm aluminum truss, while the secondary roof framework uses CS289 × 289mm square truss and aluminum ladder truss.
This hybrid arrangement allows the stage platform, elevated walls, roof and side production areas to be organized as separate but coordinated structural zones.
The connection between these zones, their load paths and their foundations must be shown clearly in the final production and assembly drawings.
Customers comparing this system with other large-stage configurations can review our stage system solutions and roof truss product range.
The product is described as a 20 × 18 × 12m system.
Before production, the quotation and drawings should confirm that these dimensions represent:
Stage width: 20m
Stage depth: 18m
Nominal overall structure height: 12m
Side wings: two nominal 10m-wide structures
The drawings should also state:
Finished stage deck height
Clear height beneath the roof
Overall external width including both wings
Overall foundation footprint
Distance between roof supports
Usable LED or speaker area on each wing
Required safety clearance around the structure
The term “12m high” should not be used without clarifying whether it refers to total external height, roof-support height or clear working height.

The 20m × 18m Ringlock Stage + Full Aluminum Roof Truss Hybrid System is the gold standard for major outdoor concerts, festivals, and televised events. Combining the unmatched strength and modularity of genuine Ringlock all-round scaffolding with a high-performance aluminum spigot/bolt roof truss, this complete solution delivers a massive 20-meter-wide × 18-meter-deep performance platform surrounded by 12-meter-high Ringlock truss walls and two giant 10-meter-wide side wings.
Perfect for supporting enormous LED video walls, multiple line-array PA clusters, complex lighting rigs, and special effects while maintaining total ground-supported stability using counterweight water bags or ballast. The integrated pole arms and extensive rigging points give production teams unlimited creative freedom.
Fast to erect, fully certified (TUV/SGS), and trusted worldwide by top touring productions – this is the ultimate turnkey stage system when only the biggest and most reliable will do.
This type of hybrid system may be configured for:
Large outdoor concerts
Music festivals
Public celebrations
Stadium productions
Touring shows
Religious events
Televised performances
Government ceremonies
Large LED-based event productions
Temporary event infrastructure
Suitability for a specific project depends on the final stage load, roof equipment, LED layout, speaker arrangement, site conditions and local approval requirements.
For broader planning principles, customers can review our safety standards and engineering constraints.
The title refers to LED walls and line-array systems, but the side wings and roof should not be described as suitable for unlimited equipment loads.
Before recommending a configuration, the customer should provide:
LED screen dimensions
Total LED screen weight
Hanging-bar details
Line-array weight per side
Lighting fixture list
Fixture positions
Cable and distribution loads
Scenic and banner loads
Special-effects equipment
Dynamic or moving equipment
Proposed rigging-point locations
Product dimensions alone cannot establish the permitted suspended load.
Dragon Stage can provide experience-based configuration recommendations, available product specifications, fabrication information, assembly drawings and standard product load information. The final arrangement must remain within the verified limits of the supplied system.
This is a large temporary structure and should be assembled by an experienced installation team using approved drawings and lifting procedures.
A general installation sequence may include:
Confirm the site boundary, finished dimensions and foundation layout.
Assess the ground and prepare suitable bearing surfaces.
Set out the Ringlock stage and wall base positions.
Establish one complete, level and braced reference bay.
Continue installing standards, ledgers and diagonal braces progressively.
Install the stage support beams and deck panels.
Assemble the primary and secondary aluminum roof structures at the designated level.
Install the electric hoists, controllers and approved lifting connections.
Lift the roof in a coordinated and controlled sequence.
Complete the Ringlock walls and side wings according to the drawings.
Install and tension the PVC canopy only at the specified stage of assembly.
Install production equipment according to the approved loading layout.
Inspect all connections, bases, braces, decks, hoists and rigging points.
Complete operational handover and weather-response planning.
Temporary stability must be maintained throughout installation. A structure that is stable when completed may still be unstable during intermediate assembly stages.
No universal wind-speed capacity should be published for this structure without evaluating the complete installation.
Wind response depends on:
Installed roof and wall fabric
LED screen area
Banners and scenic panels
Open or enclosed stage sides
Structure height
Foundation and ground condition
Ballast or anchor arrangement
Surrounding terrain and buildings
Equipment distribution
Local weather exposure
Emergency lowering or evacuation procedures
The LED walls, roof canopy and side coverings can create substantial wind-exposed areas.
Dragon Stage can provide product information, configuration recommendations and available manufacturing documents. We do not include free site-specific wind calculations, local permit approval, PE stamps or signed structural calculation reports.
When local approval or site-specific structural verification is required, the customer should engage an appropriately licensed engineer in the project location.
The quotation should divide the project into clearly identified modules.

This must be confirmed in the itemized quotation.
The page appears to list the 20 × 18m Ringlock stage, aluminum roof with motor hoisting system, and Ringlock wall or wing system as separate selectable modules. Therefore, the displayed price range should not automatically be interpreted as the price of the complete hybrid system.
The quotation should show the price, packing information and included components for each module separately, followed by the total price for the complete selected configuration.
The wings may be configured for production equipment, but their permitted use depends on the final structural layout and the actual equipment loads.
Customers should provide the LED dimensions and weight, line-array weight, suspension positions and proposed rigging arrangement. The allowable configuration must then be checked against the available product information and system limits.
The existence of a Ringlock wing does not by itself confirm a specific LED or speaker capacity.
A fixed wind speed cannot be stated from the product dimensions alone.
Wind performance depends on the roof canopy, LED screen area, side coverings, equipment arrangement, foundation, ballast or anchors, ground conditions, surrounding terrain and local requirements.
Dragon Stage can provide experience-based configuration assistance and available product documentation. Free site-specific wind calculations, PE stamps, permit approval and signed structural calculation reports are not included.
The customer should engage a licensed local engineer when project-specific verification or authority approval is required.
