EVT290S-C900 29.52-Foot F34 Square Truss Circle.
A 9-Meter Circle Built from 12 × 30-Degree Arc Sections.
The EVT290S-C900 is a 9.0 m / 29.52 ft circular aluminum truss system built from twelve matching 30-degree curved arc segments. The smaller arc increment provides more frequent connection points around the circle than a 45-degree arc system. Assemble all twelve sections into a complete 360-degree circle with an 8.42 m / 27.62 ft inside opening, or use selected arcs for 30-degree turns, 90-degree corners, half circles, wraparound structures, radial forms, and custom F34 square-truss builds. Every configuration must be evaluated for its exact support, rigging, loading, and engineering requirements.
Product Facts
Product Overview
Twelve 30-Degree Arcs Form One Complete 9-Meter Circle.
The EVT290S-C900 forms a complete 9.0 m / 29.52 ft circular truss assembly from twelve matching 30-degree arcs. The completed circle provides an 8.42 m / 27.62 ft internal opening around a broad central area. The twelve-section geometry places a structural connection at every 30 degrees, allowing circular and radial planning at smaller increments than the 45-degree arc systems used in other circle configurations. Use the complete ring where a continuous perimeter is required, or plan selected arcs into a compatible F34 / EVT290S truss system for custom curves. The finished configuration—not individual components—determines the applicable support and load requirements.
30-Degree Arc Configurations
Twelve 30-Degree Arcs Create More Circular Configurations.
The C900 is configured as twelve matching 30-degree arcs. This allows a full circle to be built in smaller geometric steps, creating useful configurations at 30-degree intervals. One arc makes a 30-degree turn; three arcs create a 90-degree quarter circle; six arcs create a 180-degree half circle; nine arcs create a 270-degree wraparound form; and all twelve arcs form the full 360-degree ring. Combine selected arcs with compatible F34 / EVT290S sections only after the completed structure has been planned and reviewed.
Do not apply completed-circle assumptions to a partial circle, arch, wraparound form, or mixed straight-and-curved structure. Confirm its actual connections, support locations, attachments, applied loads, and engineering requirements before use.
What the Arcs Can Build
Circular Geometry for Large-Scale Perimeters and Custom Structures.
The C900’s 30-degree arc system is useful where a broad 9-meter circular perimeter and smaller arc increments are both important. Build a complete ring around a large central subject, or use selected segments to form planned curves, partial wraps, large arches, radial structures, and rounded boundaries. Applications may include approved lighting, cameras, sensors, displays, graphics, scenic elements, cabling, and other attachments, but all equipment positions and loads must be evaluated as part of the finished structure.
Included Components
Twelve 30-Degree Arcs with Hardware for Every Circle Connection.
The complete C900 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 C900 Arcs in Compatible F34 Square Truss Structures.
The C900 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, and supporting documentation are verified. Combining 30-degree arcs with straight truss can create custom radial or rounded structures, but the completed assembly must be evaluated for its actual support method, attachments, and loads.
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 Geometry, Then Lift Under an Approved Plan.
The complete C900 system weighs 334 lb / 151.5 kg and includes twelve curved arc sections with twelve hardware sets. Assemble the intended structure on a clean, level surface with trained personnel and the current manufacturer instructions. For a full circle, arrange all twelve arcs in sequence before joining any section. For a partial curve or custom structure, verify component order, orientation, end conditions, support plan, and hardware requirements first. Never force a connection into alignment.
Safety and Engineering
A 9-Meter Circle Requires A Carefully Calculated Rigging Plan.
Circular truss loads must be evaluated for the completed circular geometry—not by substituting straight-span assumptions. A full 12-arc circle, a six-arc half circle, a nine-arc wraparound form, and any mixed straight-and-curved structure have different support conditions. Review support-point quantity and locations, end conditions, attachments, fixture locations, connection condition, dynamic and lateral forces, environmental exposure, and the 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-C900 Questions.
How many arcs make the complete C900 circle?
The complete C900 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 C900 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 C900 measures 9.0 m / 29.52 ft outside diameter with an 8.42 m / 27.62 ft inside opening. The documented complete-system weight is 334 lb / 151.5 kg.
