The EVT290S is the core product line at Truss Genius — a 290mm square four-chord truss series with the widest selection of lengths, configurations, and accessories on the site. If you are building a trade show booth, staging an exhibition, or designing an overhead structure for a live production, the EVT290S is likely where your build starts.

The square profile is one of the reasons this series is so widely used. Because all four chords carry load equally and the cross-section is symmetrical, hardware and fixtures mount cleanly from any approach angle. That matters in trade show and exhibition environments where the structure is visible on multiple sides and aesthetics are part of the brand presentation.

This category covers straight sections in a wide range of lengths, corner pieces, couplers, base plates, and full configured systems. Event producers, exhibit builders, and stage designers all work with the EVT290S because it hits the medium-duty performance range that covers the majority of ground-supported and overhead applications in live events and exhibition work. The 50mm chord tubes are compatible with standard production clamps, giving you flexibility when sourcing hardware from different suppliers.

Applications for the EVT290S span trade show booth frames, overhead structures for corporate events, exhibition architecture, stage canopy systems, and brand activation builds. Because the system is modular, components from different configurations share the same fittings — sections can be redistributed across projects, reconfigured between shows, or expanded as your inventory grows. Browse by length or system type to find the sections that fit your current build requirements.
