The BS400 aluminum bolt-connected truss system is a medium-large size modular truss structure designed for applications requiring higher rigidity, longer spans and stronger structural performance compared with smaller truss systems.
The system adopts a 400mm × 400mm square truss section with 50mm aluminum round tube main chords and bolt-connected joints.
The BS400 series is commonly used for:
Large lighting truss structures;
Outdoor roof truss systems;
Exhibition structures;
Mechanical support frameworks;
Event and temporary structures.
The modular bolt connection design allows the truss sections to be assembled into different lengths and configurations according to project requirements.
The BS400 bolt-connected aluminum truss consists of:
Component | Description |
|---|---|
Main Chords | 50mm aluminum round tubes providing the primary load-bearing structure |
Vertical Bracing | Vertical support members improving structural stability |
Diagonal Bracing | Diagonal members forming triangular load-transfer structures |
End Plates | Aluminum connection plates for bolt assembly |
Bolt Joint System | Detachable connection system for modular installation |

The BS400 system is suitable for:
Large event lighting bridges;
Concert lighting structures;
Exhibition lighting frameworks;
Fixed and temporary lighting installations.
Compared with smaller truss systems, the larger 400mm × 400mm cross-section provides improved stiffness and better load distribution for larger lighting equipment.
Related products:
BS400 can be used as a structural component for:
Outdoor event roofs;
Festival canopy structures;
Temporary performance structures;
Exhibition roof systems.
For outdoor applications, the complete structure needs to consider:
Wind load;
Roof covering material;
Span length;
Support conditions;
Foundation design.
Related engineering reference:
Typical applications include:
Exhibition booths;
Commercial display structures;
Brand activation frameworks;
Decorative aluminum structures.
Related application:
The BS400 uses a bolt-connected aluminum truss system.
Advantages:
Different lengths can be connected together to create customized structures.
The detachable structure reduces shipping volume and improves logistics efficiency.
Components can be reused for different events and temporary structures.
Compared with spigot-connected systems, bolt-connected trusses provide strong mechanical connection and are commonly selected for applications requiring repeated installation and customized configurations.
The BS400 truss is a standard structural component. The final structural capacity depends on:
Overall span;
Applied load;
Equipment weight;
Installation method;
Environmental conditions.
For outdoor roof structures, wind load is one of the most important design factors. The complete system should be evaluated according to project requirements.

Related categories:
BS400 aluminum truss is mainly used for lighting structures, outdoor roof trusses, exhibition frameworks and temporary event structures requiring higher rigidity.
The BS400 truss has a square cross-section of 400mm × 400mm with 50mm aluminum round tube main chords.
The main difference is the cross-section size.
BS400 has a larger 400mm × 400mm structure, providing higher rigidity and better suitability for larger spans and heavier applications compared with BS350.
Yes. BS400 can be used as a component of outdoor roof truss structures. However, the final design should consider wind load, roof material, span and supporting conditions.
Yes. Standard lengths are available, and customized lengths or special connection sections can be manufactured according to project requirements.
The drawings shown in this archive represent Dragon Stage's standard BS400 bolt-connected aluminum truss design capability.
Actual structural applications should be evaluated according to project requirements, loading conditions, installation environment and applicable safety requirements.
The BS400 system provides a flexible solution for professional lighting structures, exhibition frameworks and outdoor temporary structures.
