Custom 400×400mm Aluminum Bolt Truss Lighting Structure (Pillar & Beam Truss System for Events and Stage)

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:

• large lighting loads

• custom stage layouts

• exhibition and architectural installations

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

Bolt truss advantages:

• higher rigidity

• better for permanent or semi-permanent structures

• lower cost

Spigot truss advantages:

• faster installation

• preferred for touring systems

Material Engineering Matters

Performance depends on aluminum grade:

→ 6061-T6 vs 6082-T6 Aluminum

Using incorrect material data can lead to safety risks:

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.
