Why Choose Our Bolt Plate Truss?

🔩 Ultra-Secure Bolt Plate Connection
Reinforced side mounting plates with pre-drilled bolt holes lock sections together with zero shifting or loosening — even under long-term, high-altitude heavy loads. Perfect for extra-wide overhead roof spans.

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

🔧 Modular & Fully Customizable
Combine with 2/6-way corners, cube connectors, and base plates to build straight rigs, square roof frames, arched backdrops, and multi-layer structures. Custom lengths from 0.5m to 6m available.

Bolt Plate vs. Spigot Truss — Why Bolt Plate Wins

1. Stronger tensile force — no sagging on ultra-long wide-span overhead hoisting
2. Thickened connection plates eliminate spigot bending & slipping under heavy loads
3. Premium silver finish suits high-end weddings, corporate events & fashion shows
4. Rust-proof aluminum body extends service life — ideal for rental businesses
5. Tight, uniform splicing gap keeps the full truss frame flat after assembly
