Complete Engineering Guide for Event Truss System Planning

What is truss design and configuration?

Truss design and configuration refers to the process of selecting the correct truss system type, structure layout, load capacity, and connection method to safely support lighting, LED screens, audio systems, and stage elements for events, exhibitions, and construction applications.

A proper truss configuration combines structural engineering principles, material selection, and application requirements to ensure safety, efficiency, and installation feasibility.

• * Purpose: Structural support for lighting, LED, audio, stage
• * Key Factors: Span, load, system type, connection method
• * Common Systems: Aluminum truss, roof truss, LED truss, Layher system
• * Structure Types: Ground support, hanging system, truss tower
• * Safety Focus: Load calculation, material strength, installation method

Step 1 — Define Span & Event Requirements

The first step in truss design is defining the size and environment:

• Indoor vs outdoor
• Small stage vs large concert
• Temporary vs long-term structure

For large outdoor systems, consider:

For lighting-focused setups:

For LED screen structures:

Step 2 — Load Analysis & Structural Safety

Every truss system must be designed based on load:

• Lighting load
• Speaker load
• LED screen weight
• Wind load (critical for outdoor)

Step 3 — Choose the Right Truss System Type

Different applications require different systems:

• Standard aluminum system →

• Event structure system →

• Heavy-duty structural system →
  Layher Truss System

Layher is typically used when aluminum truss is not sufficient for load or structural complexity.

Step 4 — Select Structural Configuration

There are 3 main configurations:

Ground Support System

• Most common
• Easy installation
• Suitable for medium to large events

Hanging System

• Used in venues with rigging points
• Clean visual appearance

Tower / PA System

• Used for speaker lifting
• High vertical load

Step 5 — Material & Connection System

Two key decisions:

Material Selection

• Aluminum → lightweight, fast installation
• Steel / Layher → high load, structural stability

Connection Type

• Spigot truss → fast assembly
  Standard Spigot Truss
• Bolt truss → lower cost, slower

How do I choose the right truss system?

It depends on load, span, and application. For lighting events, aluminum truss is sufficient. For heavy structures, Layher systems are recommended.

What is the safest truss configuration?

Ground support systems are the safest for most events, but proper load calculation and installation are essential.

Aluminum vs Layher — which is better?

• Aluminum → lightweight, flexible
• Layher → high load, structural stability

What is the most common truss size?

• 290mm → small to medium events
• 400mm → larger structures
