This Professional 20m x 30m Multi-Grid Truss System is engineered for maximum-scale event productions that require vast overhead coverage and exceptional load-bearing stability. By utilizing a double-grid architecture, this system provides a massive, continuous rigging platform for high-end technical requirements.

• Dual-Grid Engineering: The structure is composed of two interconnected 15m deep by 20m wide grids, creating a total footprint of 30 meters in depth and 20 meters in width.

• Stadium-Scale Dimensions: Standing at a professional 8-meter height, this system offers the necessary clearance for large LED walls, complex aerial performances, and advanced theatrical lighting.

• Enhanced Structural Support: Built on a multi-tower ground support system featuring heavy-duty vertical pillars with reinforced outriggers and stable base plates to ensure safety across the entire 600-square-meter area.

• Versatile Rigging Points: The comprehensive grid layout provides a high density of hanging points, ideal for distributed audio systems, massive lighting arrays, and decorative event branding.

• Industrial Durability: Fabricated from high-strength 6061-T6 aluminum alloy, ensuring long-term durability, weather resistance, and an excellent strength-to-weight ratio for frequent assembly and disassembly.

• Modular Scalability: While presented as a 30m deep system, the modular design allows for independent use of the 15m x 20m sections or further expansion based on venue requirements.

Professional 20x30x8m Heavy-Duty Aluminum Ground Support Event Truss System: Double Grid Configuration

1. Introduction

For the world's most ambitious outdoor festivals and stadium-scale productions, standard truss configurations are often insufficient. The 20x30x8m Heavy-Duty Ground Support Event Truss System by DragonStage is a structural titan, providing a massive 600 square meters of unobstructed performance space. The standout feature of this system is its Double Grid Configuration, which offers unparalleled rigging density and structural redundancy for the heaviest technical riders. With an 8-meter vertical clearance and a staggering 30-meter clear span, this system is engineered for elite designers who require a massive "canvas" for complex lighting, audio, and video integration.

2. Challenges & Solutions

The primary engineering challenge of a 30-meter span is preventing structural deflection (sagging) while maintaining a high safety factor. DragonStage solves this by utilizing 6061-T8 aluminum alloy, which provides superior yield strength and hardness compared to standard T6 alloys.

Furthermore, the Double Grid design adds a second layer of horizontal bracing, which significantly increases the "torsional rigidity" of the roof, preventing twisting under uneven loads. To manage the massive wind loads associated with a 600sqm canopy, the system utilizes a multi-tower ground support configuration (6 or 8 towers) equipped with heavy-duty outriggers and specialized ballast attachment points to ensure the structure remains a secure anchor in any environment.

3. Key Features & Benefits

This 20x30x8m system is manufactured from aerospace-grade 6061-T8 aluminum alloy. This material is solution heat-treated and cold-worked to provide the ultimate strength-to-weight ratio, ensuring the structure remains a professional, long-term asset for the most demanding global tours (Source:https://www.dragontruss.com/Aluminum-Truss-System-pd413987768.html).

The Double Grid configuration allows for flexible rigging of center-hung LED video cubes and heavy audio clusters without compromising the main structural spans.

According to international safety standards for massive temporary structures, the use of a ground-support system with synchronized electric hoists is the only safe method for managing the multi-ton lift required for a 600sqm grid (Source:https://www.plasa.org).

To ensure a complete venue solution, this system is designed for seamless integration with our modular aluminum stage platforms. These decks feature 18mm anti-slip surfaces and high load-bearing capacities, providing a stable foundation that matches the industrial grade of the overhead double-grid (Source:https://www.dragontruss.com/Aluminum-Stage-Platform-pd463987768.html).

4. FAQ Section

Q: What is the benefit of a "Double Grid"?A: It provides twice the number of rigging points and significantly increases the structural stability of the 30-meter span, allowing for heavier and more complex equipment layouts than a single-grid system.

Q: Can this 30m span support a large-scale LED video backdrop?A: Absolutely. The 6061-T8 box truss and double-grid architecture are specifically designed to support the massive weights of professional LED walls.

Q: Is the PVC canopy waterproof and fire-safe?A: Yes. Our canopies are made from 850g/m² PVC that is waterproof, UV-resistant, and meets international B1/M2 fire-retardant safety standards.

Q: How many towers are needed for this 20x30m system?A: Depending on your specific load requirements and local wind conditions, we typically recommend a 6-tower or 8-tower ground support configuration for a structure of this scale.
