Global Truss SQ-C3 ARC90 | 90° F34 Square Truss Arc | 3m Diameter Circle Segment

Global Truss SQ-C3 ARC90  (Global Truss F340742)

90-Degree Circular Square Truss Segment

The Global Truss SQ-C3 ARC90 is a 90-degree curved F34 square truss segment designed for professional stage lighting, event production, exhibition displays, and entertainment installations. Built as one of four matching sections that form a complete 9.84 ft (3m) outside-diameter truss circle, it provides a modular solution for creating circular and curved truss structures. Featuring a 290mm square truss profile, 50mm main tubing, 20mm diagonal bracing, and 2mm wall thickness, the SQ-C3 ARC90 is suitable for constructing custom lighting rigs, stage designs, and decorative truss installations. This product includes one individual 90-degree arc segment.

Global Truss SQ-C3 ARC90 Competitive Differences

• 90-Degree Circular Truss Design: Provides a quarter-circle arc section for creating curved lighting structures, circular truss configurations, and custom stage designs.
• 3m Circle Compatibility: Four matching SQ-C3 ARC90 segments assemble into a complete truss circle measuring 9.84 ft (3m) in outside diameter.
• F34 Square Truss Construction: Features a 290mm (11.42-inch) square truss profile compatible with the matching Global Truss F34 circular truss system.
• 50mm Main Tubing: Uses 2-inch (50mm) outer-diameter main tubes for structural construction and integration with compatible truss accessories.
• 20mm Diagonal Bracing: Incorporates diagonal support tubing within the square truss framework.
• 2mm Wall Thickness: Aluminum tubing construction provides a combination of structural rigidity and practical handling for professional event applications.
• Modular Circular Design: Individual arc sections allow lighting designers to create quarter-circle structures or assemble complete circular truss configurations.
• Versatile Event Applications: Suitable for concert stages, nightclub lighting, trade shows, exhibitions, DJ setups, and decorative architectural displays.

Global Truss SQ-C3 ARC90 Description

The Global Truss SQ-C3 ARC90 provides a modular curved truss solution for professional lighting designers, event production companies, and stage technicians. Featuring a 90-degree arc design, this individual segment is part of the Global Truss SQ-C3-90 circular truss system. Four matching sections can be assembled to create a complete 360-degree circle with a 9.84 ft (3m) outside diameter and approximately 7.94 ft (2.42m) inside diameter. The circular design makes it suitable for creating distinctive overhead lighting configurations, exhibition structures, stage features, and entertainment installations when properly supported and rigged.

Constructed using the F34 square truss format, the SQ-C3 ARC90 features an overall truss width of 290mm, 50mm outer-diameter main tubing, and 20mm diagonal bracing. Its 2mm tube wall thickness provides the structural characteristics of the matching F34 circular truss system. The aluminum construction and silver finish make it suitable for professional stage and event environments where curved truss structures are required.

The SQ-C3 ARC90 can be used as an individual quarter-circle segment or combined with three additional matching sections to construct a complete circular truss. This modular configuration provides flexibility for stage lighting layouts, decorative installations, and custom event designs. Its curved geometry allows designers to incorporate circular elements into larger production structures, creating visual arrangements that differ from conventional straight truss configurations.

Designed for professional staging and installation applications, the SQ-C3 ARC90 is suitable for production companies, lighting rental businesses, nightclub installations, trade show exhibitors, and entertainment venues. Whether used as part of a complete circular lighting rig or a custom curved truss design, it provides a practical structural component for professional event setups. Appropriate supporting structures, connection hardware, and verified rigging calculations are required for safe installation.
