How to Build a Global Truss F34 20x20x10 ft Square Booth with a 7.51 ft Center Circle Truss
The Ultimate Trade Show Booth Setup Guide from FamousStages.com
If you want a trade show or event booth that instantly says “We’re the real deal,” the Global Truss F34 20x20x10 ft Square Booth with Center Circle Truss is the perfect system. This setup is bold, symmetrical, and engineered from premium aluminum truss — lightweight, durable, and trusted by DJs, exhibitors, lighting techs, and production managers everywhere.
Below is the complete step-by-step guide on how to build this stunning Global Truss display booth, using all the exact F34 components required.
🔧 Materials You’ll Need
-
8× F34 Box Truss 9.02 ft Vertical Posts
For the outer square vertical columns. Total height with junction block: ≈9.97 ft. -
12× ST-UJB-12 Universal Junction Blocks
8 for the top of the outer vertical posts, 4 for the N–E–S–W mounting points on the inner circle. -
1× SQ-C2 90° Truss Circle 6.56 ft (4 Quarter Segments)
Assembled diameter becomes 7.51 ft once ST-UJB-12 blocks are attached. -
8× F34 Box Truss 8.2 ft
Used to form the horizontal sides of the outer square. -
4× F34 Box Truss 4.92 ft
Used to connect outer midpoint blocks to the inner circle truss. -
8× SQ-4137 Base Plates
Heavy-duty foundations for all eight vertical posts. -
16× ST-UJB/C-12 ½ Couplers with Alien Bolts
For secure, reliable connections throughout the system.
This configuration forms a clean and powerful structural layout ideal for lighting truss, DJ truss, stage trussing, display booth truss setups, and trade show installations.
🏗️ Step 1: Set Your Foundation
Start by laying out your 8 SQ-4137 base plates in a perfect 20×20 foot square.
For accuracy, the total length of each side equals:
0.95' (UJB-12) + 8.2' (truss) + 0.95' (UJB-12) + 8.2' (truss) + 0.95' (UJB-12) = 19.25 ft
This is the real-world truss-to-truss dimension.
Mount each 9.02 ft F34 vertical post onto its base plate using couplers.
Place an ST-UJB-12 on top of each vertical post — this brings the total height to about 10 ft (9.97 ft).
Pro Tip: Measure twice, adjust once. A perfectly square base makes the entire assembly smoother and faster.
The foundation is now set for your Global Truss F34 booth

🧱 Step 2: Build the Outer Square Frame
With all eight posts standing, begin forming the upper square.
Attach two 8.2 ft F34 truss segments between every group of three ST-UJB-12 junction blocks.
Repeat on all four sides.
Once complete, you’ll have a strong, symmetrical approximately 20x20 square truss frame (real world truss dimension is 19.25'x19.25') overhead — the perfect platform for:
-
LED lighting
-
Moving heads
-
LED video screens
-
Hanging banners
-
Trade show signage
This is the backbone of your display booth truss or trade show booth truss structure.

🔄 Step 3: Assemble the 7.51 ft Center Circle Truss
Your booth’s showpiece is the center circle. You can assemble this on the ground first, then raise it along with the truss connectors to the outer square structure.
-
Connect all four SQ-C2 quarter arcs using the conical connectors.
-
Once assembled, place an ST-UJB-12 on the N–E–S–W points of the circle.
-
The circle now measures 7.51 ft in diameter when measured from ST-UJB-12 to ST-UJB-12.
This center circle truss is perfect for:
-
Spotlighting
-
Hanging moving heads
-
Logo projection
-
Decorative lighting
-
Branding elements
Your center circle truss lighting design will be a major visual centerpiece.

🔗 Step 4: Connect the Outer Frame to the Center Circle
Now bring the entire booth design together.
Use your 4.92 ft F34 truss segments to connect:
Each outer middle ST-UJB-12 → to the N, E, S, and W junction blocks on the circle
This creates the iconic “radial” look of the booth.
Structurally, it stabilizes the circle; visually, it adds architectural energy and modern symmetry.
This step transforms the booth into a premium Global Truss trade show system suitable for:
-
DJ stage setups
-
Corporate activations
-
Exhibits
-
Convention booth truss layouts
-
Concert merchandise booths

💡 Step 5: Tighten, Inspect & Light It Up
Walk around the entire structure and verify:
-
All couplers are tightened
-
All Alien Bolts are secure
-
Junction blocks are properly seated
-
Truss lines are straight and balanced
Your finished booth can now confidently support:
✔ Lighting truss fixtures
✔ Video panels
✔ Printed signage
✔ Hanging décor
✔ DJ lighting truss rigs
✔ Portable stages and risers nearby
You now have a rock-solid, professional-grade structure built entirely from Global Truss F34 components.
