What is a 400×400mm Bolt Truss Lighting Structure?
A 400×400mm bolt truss lighting structure is a heavy-duty modular system composed of vertical pillars and horizontal beams, designed to support lighting equipment, LED screens and stage installations in concerts, exhibitions and large event environments.
Product Overview
This system uses 400×400mm aluminum bolt truss to form a stable pillar-and-beam framework, suitable for projects requiring higher load capacity and structural rigidity.
Unlike standard lighting truss setups, this structure is designed for:

Structural Configuration
This system typically includes:
Vertical pillars (400×400mm bolt truss)
Horizontal beams (400×400mm truss span)
Base plates and connection components
Optional extensions for larger spans
This creates a rigid frame structure similar to a gantry or portal system.

Engineering Insight
Structure Type: Frame vs Hanging System
This system works as a self-supporting frame, not just a hanging truss.
That means:
load transfers through pillars to ground
reduced reliance on roof rigging
better stability for outdoor use
Bolt Connection vs Spigot Connection

FAQ
Is 400×400mm truss necessary?
Only for medium to heavy load systems or larger spans. Smaller events usually use 290mm truss.
Can this system be customized?
Yes, this is a fully customizable structure based on load, span and application.
Is this suitable for outdoor use?
Yes, especially for self-supporting structures where hanging points are not available.
What is the difference from roof truss systems?
Roof truss includes covering systems, while this is primarily a structural support frame.
