4-Chord Square Aluminum Box Truss – Premium Bolt Plate Stage Lighting Trussing

The foundation of every great stage rig. Our premium bolt plate 4-chord square aluminum box truss is the mainstream load-bearing main frame trusted by professional riggers for concert roofs, wedding arches, trade show frames, and more. Constructed from aviation-grade 6061-T6 aluminum alloy with a polished silver finish, it delivers the perfect balance of lightweight portability and the superior tensile strength that large-span, high-rise overhead rigs demand — built to perform event after event.

Why Choose Our Premium Bolt Plate Truss?

🔩 Thickened Bolt Plate Secure Connection
Reinforced side mounting plates with pre-drilled bolt holes lock multiple truss sections seamlessly — zero shifting or loosening under long-term, high-altitude heavy loads. Ideal for large-span, high-rise truss roof construction where connection integrity is non-negotiable.

✨ Polished Silver Anti-Oxidation Finish
Bright natural silver aluminum surface resists rust and oxidation without paint — no peeling, no repainting needed. Smooth, burr-free edges protect your lighting clamps, cables, and equipment during every setup and teardown.

🔧 Modular & Fully Customizable
Combine with 6-way cube connectors, multi-angle corners, and mobile base plates to build straight rigs, square roof frames, arched backdrops, and multi-layer stereo structures. Custom lengths from 0.5m to 4m available for any venue or event scale.

Bolt Plate vs. Spigot Truss — Why Bolt Plate Is the Professional Standard

1. Stronger overall tensile force — the professional standard for large-span high-altitude heavy-load hoisting
2. Thickened side plates eliminate spigot bending and slipping risks under extreme overhead loads
3. Polished silver finish integrates seamlessly with high-end wedding, corporate & fashion event aesthetics
4. Rust-proof aluminum body requires no repainting — maximizes service life for rental fleets
5. Uniform tight splicing gap ensures the full assembled truss frame stays stable and shake-free
