EVT290S-C1000 32.80-Foot F34 Square Truss Circle.
12 × 30-Degree Arcs for Large Circular Truss Structures.
The EVT290S-C1000 is a 10.0 m / 32.80 ft circular aluminum truss system built from twelve matching 30-degree curved arc segments. Assemble all twelve sections into a complete 360-degree circle with a 9.42 m / 30.91 ft inside opening, or use selected arcs for 30-degree turns, quarter circles, half circles, wraparound forms, radial structures, and custom F34 square-truss builds. At ten meters in diameter, the C1000 creates a large circular perimeter for projects that require substantial central clearance. Every completed configuration must be evaluated for its actual support, rigging, loading, and engineering requirements.
Product Facts
Product Overview
Twelve 30-Degree Arcs Form One Complete 10-Meter Circle.
The EVT290S-C1000 forms a complete 10.0 m / 32.80 ft circular truss assembly from twelve matching 30-degree arcs. The completed circle has a 9.42 m / 30.91 ft inside opening around a broad central area. Twelve individual arc sections place connection points at 30-degree intervals around the complete circle, allowing selected segments to be planned into compatible circular, radial, and custom truss structures. The completed configuration—not the individual arcs alone—determines the appropriate support method, rigging plan, attachment locations, and load review.
30-Degree Arc Configurations
Build Large Curves in 30-Degree Increments.
The C1000 uses twelve matching 30-degree arcs. One arc creates a 30-degree turn; three create a 90-degree quarter circle; six create a 180-degree half circle; nine create a 270-degree wraparound form; and all twelve create the complete 360-degree ring. The 30-degree increment supports planned curve transitions and radial arrangements within compatible F34 / EVT290S truss systems. Every partial-circle or mixed straight-and-curved configuration has its own support conditions and must be reviewed separately from the complete circle.
Do not apply full-circle assumptions to a partial circle, arch, wraparound form, or mixed straight-and-curved structure. Determine connections, supports, attachments, loads, and engineering requirements for the actual finished configuration.
What the Arcs Can Build
Large Circular Structures for Broad Central Areas and Custom Curves.
The C1000 provides a 32.80 ft circular perimeter around a 30.91 ft inside opening. This scale can suit large stage surrounds, architectural and exhibit structures, large-object display zones, motion-capture or tracking volumes, camera and lighting arrangements, and custom curved structures. A complete ring provides positions around a shared center; selected arcs can form gradual turns, large arches, partial wraps, rounded boundaries, and radial truss arrangements. All fixtures, graphics, cameras, lighting, sensors, scenic material, cable paths, and other attachments must be evaluated as part of the complete approved structure.
Included Components
Twelve 30-Degree Arcs with Hardware for Every Circle Connection.
The complete C1000 package is configured as twelve matching 30-degree curved arc sections with twelve connection-hardware sets. The per-arc hardware pattern is four conical couplers, eight tapered pins, and eight R-clips; across the complete circle, that equals forty-eight couplers, ninety-six tapered pins, and ninety-six R-clips. Confirm current package contents and inspect all components before assembly.
Inspect every active chord connection and verify all specified couplers, pins, and R-clips are correctly installed and retained before the structure is moved, lifted, suspended, or loaded.

System Compatibility
Use C1000 Arcs in Compatible F34 Square Truss Structures.
The C1000 uses 290 mm square truss geometry, 50 mm main chords, and a conical connection system. It is designed for compatible EVT290S, F34, and matching 290 mm square conical systems where receiver spacing, coupler dimensions, chord geometry, component orientation, connection condition, and applicable documentation are verified. Integrating the 30-degree arcs with straight truss can create large custom curves and radial structures, but the completed assembly requires support and load review for the actual layout.
Verify component interfaces, manufacturer documentation, required hardware, and project-specific engineering before mixing brands, configurations, or load-bearing components.
Assembly Overview
Lay Out All Twelve Arcs, Confirm the Shape, Then Lift Under an Approved Plan.
The complete C1000 circle weighs 374 lb / 169.6 kg and uses twelve curved arc sections with twelve hardware sets. Assemble the intended structure on a clean, level surface with trained personnel and current manufacturer instructions. For the full circle, arrange all twelve arcs in sequence before joining sections. For a partial curve or custom structure, confirm component order, orientation, end conditions, support plan, and hardware requirements before assembly. Never force a connection into alignment.
Safety and Engineering
A 10-Meter Circle Requires A Project-Specific Rigging Plan.
Circular truss loads must be evaluated for the completed circular geometry—not by applying straight-span assumptions. A full 12-arc circle, a six-arc half circle, a nine-arc wraparound form, and any mixed straight-and-curved assembly have different support conditions. Review support-point quantity and locations, end conditions, attachments, fixture positions, connection condition, dynamic and lateral forces, environmental exposure, and actual applied loads. Use current load documentation for the exact configuration and obtain qualified rigging and engineering review for overhead, load-bearing, outdoor, public-facing, or regulated installations.
Product Questions
EVT290S-C1000 Questions.
How many arcs make the complete C1000 circle?
The complete C1000 circle uses twelve matching 30-degree curved arc segments to form a 360-degree ring.
What can the 30-degree arc system build?
One arc makes a 30-degree curve, three arcs make a 90-degree quarter circle, six arcs make a 180-degree half circle, nine arcs make a 270-degree wraparound form, and all twelve arcs make the full 360-degree circle. Each finished configuration needs its own support and load review.
What hardware is included with the complete C1000 circle?
The complete circle includes twelve 30-degree arcs and twelve hardware sets. Based on four couplers, eight tapered pins, and eight R-clips per arc, the full circle includes forty-eight couplers, ninety-six pins, and ninety-six R-clips. Confirm current package contents before assembly.
What are the complete circle dimensions and weight?
The C1000 measures 10.0 m / 32.80 ft outside diameter with a 9.42 m / 30.91 ft inside opening. The documented complete-system weight is 374 lb / 169.6 kg.
