In the world of LED displays, proper support structures are just as important as the screens themselves. One essential structure often used in live events, exhibitions, and rental installations is the LED Screen Ground Support Truss. This article explains what it is, when it’s needed, and how to install it correctly to ensure both stability and visual performance.
一、What Is an LED Screen Ground Support Truss?
An LED Screen Ground Support Truss is a modular metal frame system used to safely support LED displays from the ground up, especially when no wall or ceiling structure is available for hanging or mounting.
These trusses are typically made of aluminum or steel, and they’re designed to:
- Hold heavy LED panels vertically
- Provide adjustable height and angle support
- Ensure stability in outdoor or temporary indoor setups
二、What Types of LED Screens Need Ground Support Trusses?
Ground support trusses are commonly used with rental and stage LED displays, particularly:
- Rental LED screens (P2.9, P3.9, P4.8, etc.)
- Curved LED displays needing extra structural integrity
- Large-format outdoor displays
- LED video walls for concerts or fashion shows
They are ideal for modular LED cabinets that are stacked or joined together to form a seamless screen. If your LED display is not mounted to a permanent structure, a ground support truss becomes essential.
三、When Do You Need an LED Ground Support System?
You should consider using a ground support truss system in the following scenarios:
✅ Temporary Installations
If your LED screen is set up for a one-time event, such as a concert, trade show, or outdoor festival, ground support allows for quick and secure assembly.
✅ No Mounting Infrastructure
In locations without walls, ceilings, or beams to hang a screen — such as open-air venues or large halls — ground trusses provide reliable freestanding support.
✅ Outdoor Applications
For billboards, outdoor advertising, or public displays, ground support trusses can be stabilized with weights or anchors to withstand wind and weather.
✅ Flexible Layouts
If your screen layout needs to change frequently — such as for a roadshow or touring setup — ground trusses offer modularity and easy dismantling.
四、How to Install an LED Screen Ground Support Truss
Installing an LED ground support truss is a straightforward but crucial process. Here’s a step-by-step overview:
1. Prepare the Base Structure
- Begin with heavy-duty base plates to provide a solid foundation.
- Ensure the ground is level and stable, especially for outdoor setups.
2. Assemble the Truss Frame
- Use vertical truss towers and crossbars to form the main frame.
- Connect truss sections with secure clamps and pins.
3. Attach the LED Display
- Use hanging bars or rigging frames to safely mount the LED panels.
- Start from the bottom row and stack upward, ensuring each module is locked in place.
4. Secure the System
- Add back support arms or outriggers to prevent tipping.
- For outdoor use, sandbags or concrete blocks can add extra stability.
5. Test and Align
- Power on the screen to test functionality.
- Adjust tilt or height as needed using the truss system’s adjustment options.
五、Conclusion
Whether you’re planning a stage performance, setting up an outdoor digital billboard, or organizing a trade show booth, an LED Screen Ground Support Truss is an essential tool for safe and effective LED display installations. It provides flexibility, safety, and stability — especially when ceiling or wall mounting is not an option.
