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

When the load is heavy and the span is wide, bolt plate is the right call. Our bolt plate 4-chord square aluminum box truss is the core load-bearing frame for professional stage rigging projects that demand maximum structural integrity. Built from aviation-grade 6061-T6 aluminum alloy with a polished silver finish, it combines lightweight mobility with the superior tensile strength that high-rise, large-span overhead rigs require — from concert lighting roofs to wedding arch backdrops and trade show booth frames.

Why Choose Our Bolt Plate Truss?

🔩 Thickened Bolt Plate Secure Connection
Reinforced side mounting plates with pre-drilled bolt holes lock multiple truss sections with zero shifting or loosening under long-term, high-altitude heavy loads. The bolt plate system delivers superior tensile force — the right choice for wide-span overhead roof construction where spigot connections fall short.

✨ 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 structures. Custom lengths from 0.5m to 4m available to suit any venue or event scale.

Bolt Plate vs. Spigot Truss — Why Bolt Plate Wins for Heavy Loads

1. Superior tensile force — safer for large-span, high-altitude, heavy-load overhead hoisting
2. Thickened side plates eliminate spigot bending and slipping risks under extreme loads
3. Polished silver finish suits high-end weddings, corporate events & fashion shows
4. Rust-proof aluminum body needs no repainting — lower maintenance cost for rental fleets
5. Uniform tight splicing gap keeps the full truss frame stable and shake-free after assembly
