A Complete Overview of Temporary Event Structures, Technical Systems and Safety Engineering
Large stadium concerts are not simply built around a stage. Behind every successful performance is a complex temporary engineering system that combines structural design, modular construction, technical production and operational planning.
The 2026 Guangzhou Pearl Beer Festival Music Festival provides a real-world example of how a large outdoor concert environment is created inside a stadium. The project included a main stage structure, FOH control area, relay speaker towers, LED screen support structures, temporary walkways, backstage facilities and multiple safety management systems.
This article provides an overview of the complete concert structure and connects each engineering topic to detailed technical analysis.

Project Overview
Project Name: 2026 Guangzhou Pearl Beer Festival Music Festival
Construction Period: July 10 – July 21, 2026
Performance Date: July 19, 2026
Project Type: Large Outdoor Stadium Concert Structure
Engineering Scope Included:
Main concert stage
Stage roof structure
FOH control structure
Relay speaker towers
LED screen support systems
Ringlock temporary structures
Walkway stage system
Backstage facilities
Temporary protection and safety systems
Unlike permanent buildings, concert structures must be designed, installed, operated and removed within a limited period while supporting large technical loads and adapting to changing outdoor conditions.
This makes temporary event structures a unique engineering discipline.
Understanding the Overall Layout of a Stadium Concert Structure
A large stadium concert is organized as a complete system rather than a single stage.
The main functional areas usually include:
Main Stage
FOH (Front of House)
Relay Speaker Towers
Audience Area
Backstage and Supporting Facilities
Technical Operation Areas
Each area has a different engineering purpose.
The main stage provides the performance platform and technical support.
The FOH acts as the central control position for audio, lighting, video and communication.
Relay speaker towers extend sound coverage throughout the venue.
Backstage and service areas support artist preparation, equipment operation and event logistics.
A detailed explanation of stadium concert layouts can be found in:
The main stage is the central structure of the entire concert environment.
It integrates:
Supporting structures
Roof systems
Lighting grids
Rigging points
LED screens
Audio systems
Performance platforms
The construction of a large concert stage requires careful coordination between structural stability, installation sequence and technical requirements.
The main stage construction process is explained in detail in:
The 4m × 6m Hybrid Ringlock FOH Control Booth is a customized Front of House structure for concert, festival, live-event, and production-control applications.
The main booth structure is built from a modular Ringlock system, while the pitched roof uses a separate aluminum frame. This combination allows the booth body, working floor, enclosure, and roof components to be supplied as one coordinated temporary-event package.
The confirmed dimensions for this configuration are:
Width: 4m
Depth: 6m
Overall structure height: 3m
Side / eave height: 2m
Roof ridge height: 2.5m
The structure also includes roof tarpaulins, side and rear/front curtain panels, aluminum roof beams, platform planks, diagonal bracing, and steel ballast-pipe components according to the supplied BOQ.
DragonStage supplies other modular temporary structures through our Ringlock Structure System product range.
The 4m × 4m Multi-Level Hybrid Ringlock FOH Control Tower is a customized Front of House control structure designed for concerts, festivals, live productions, and other temporary event applications.
This product combines a Ringlock main tower structure with an aluminum roof frame and weather-cover system, creating a compact but elevated technical-control tower for audio, lighting, video, or show-operation use.
The confirmed project dimensions are:
Width: 4m
Depth: 4m
Overall maximum height: 7m
Side height: 6m
Roof low point: 6m
Roof high point: 7m
This makes it a sloped-roof hybrid FOH tower, with the roof rising from the lower side to the higher side.
According to the supplied BOQ, the structure includes the Ringlock main body, internal planks, ladder-access components, aluminum roof beams, side-wall curtain posts, roof tarpaulin, side and front/back curtains, ballast-pipe components, and a lower auxiliary base structure.

The 24ft × 24ft Flat Roof Aluminum Truss System is a customized four-tower event truss structure with a 20ft tower height, designed for temporary stages, lighting installations, concerts, performances, corporate events, and other event-production applications.
The system uses four vertical aluminum truss towers supporting a square flat-roof truss framework. Internal cross truss members divide the overhead area into multiple rigging zones, allowing the roof framework to be configured around the actual lighting and event-equipment layout.
The drawing also shows a tower lifting arrangement with sleeve blocks, allowing the assembled upper truss grid to be positioned on the vertical towers as part of the installation process.
DragonStage manufactures flat roof systems in different dimensions and configurations. See more products in our Typical Flat Roof Truss System range.

This customized large tunnel event structure combines a 24m wide × 18m deep × 15m high tunnel aluminum truss system with a 21.96m × 14.4m × 2m high stage platform.
The upper structure uses multiple large curved aluminum truss arches connected by longitudinal truss sections, creating a wide-span architectural framework above the event area. The complete system can be supplied together with the elevated stage platform as a customized package for stadium events, ceremonies, concerts, festivals, and other large temporary productions.
The dimensions shown here come from an actual customer quotation requirement rather than a standard catalogue size.

Instead of purchasing the stage platform, roof truss, LED supports, and sound-support structures separately, customers can order them as one coordinated event-stage package from DragonTruss.
2m × 2m modular Ringlock audience viewing platform originally configured for socially distanced concert seating areas. The system features a 0.2m-high aluminum pallet platform, three-sided double-rail guardrails, an open rear entrance, adjustable steel base jacks, and a front-facing position for event or sponsor posters.
20m wide × 14m deep × 10m high custom curved roof truss system featuring six main support towers and two 2m-wide side wings for line array systems with manual hoists. Designed as a modular aluminum truss structure for concerts, festivals, live productions, and other large event applications.
This custom mobile DJ table is designed for a customer who needed one standalone DJ workstation rather than a complete stage system.
The table uses the same basic manufacturing logic as a professional aluminum stage platform: an aluminum frame, flat black working surface, rigid support structure, and replaceable modular components. However, instead of stage legs standing directly on the floor, this version is fitted with four lockable caster wheels so the complete table can be moved short distances inside a club without dismantling the DJ equipment.
The finished size is 2200mm wide × 800mm deep × 900mm high, providing a large working surface for multiple DJ players, a mixer, laptop, or controller.
