Engineering Insight
Curved Truss ≠ Straight Truss
Key differences:
load direction changes along the curve
connection precision is critical
suspension points must be balanced
Connection System Matters
This system uses:
conical coupler
safety clip
pin connection
Which ensures:
fast assembly
secure alignment

FAQ
Can this form a full circle?
Yes, two sets can be combined to form a complete circular truss.
Is 289mm truss strong enough?
Yes, it is the standard size for medium-duty lighting systems.
Can it be hung from ceiling?
Yes, but requires proper rigging and load calculation.
Can I customize the diameter?
Yes, custom sizes and segment configurations are available.
