FAQ
Q1: Can the arch shape be customized?
Yes, curvature radius, span and height can be fully customized.
Q2: What is the difference between arch and flat truss?
Arch truss improves load distribution and provides better visual impact.
Q3: Is it suitable for outdoor events?
Yes, but requires proper anchoring and wind load calculation.
Q4: What size should I choose?
Depends on span and load. See:
