Aluminum round-tube stage trusses are built for crews who need to set up fast, tear down faster, and still trust the rig with lights, speakers, or even small cars. Below is a straight-talk guide to how they go up, Modular Truss what they’re made of, and where they shine. Putting it up – no cranes, no welders
Time and muscle: two to four people, one to three hours up, one hour down.
Step 1 – mark the floor
• Sweep the area; slope must be under 3°.
• Tape out the footprint (e.g., 10 m × 6 m needs four main trusses and six cross-beams).
• Count parts: main tubes (4 m / 6 m / 8 m), modular truss system spigots, pins, flanges, base plates, and hand tools. Step 2 – feet first
• Drop adjustable base plates every 1.5–2 m.
Step 3 – frame it
• Each 6 m bay weighs about 35 kg – two people can carry it.
Step 4 – hang the kit
• Rig points are pre-drilled every 1.5 m; spread the load so no single point takes more than 50 kg.
• Shake the frame, check bolts, plug in power – done.
Step 5 – strike
What it’s made of – light but tough
Main tubes
• 6061-T6 or 6063-T5 aluminum (260 MPa tensile) – half the weight of steel.
• 6 m span weighs ~32 kg; one adult can shoulder it.
• Hard-anodised 10 µm coat shrugs off rain and indoor condensation – 5-8 year life.
Fittings
• Flanges: cast ADC12 aluminum, won’t bend after repeated use.
• Pins: zinc-plated 45# steel (600 MPa).
• Bolts: grade 8.8 carbon steel, hot-dip galvanised – they stay tight.
Where it fits – small to mid-size gigs
Indoor
• Bar residencies, corporate events, school Modular Aluminum Round Truss System talent nights – lights, LED walls, or backdrop frames. Outdoor
• Campus festivals, Lightweight Aluminum Round Truss open-air weddings, market-day stages – fine in wind up to level 5 and short showers.
Pop-up
• Trade-show booths, car launches, photo-call backdrops – build to any 3 m, 6 m, or 10 m bay you need.
Bottom line: aluminum round frame Stage Truss carry it in one van, set it up before the kettle boils, and trust it to hold whatever the show throws at it.
