Structural Components for Lighting Structures, Exhibition Systems and Outdoor Roof Truss Systems
3767-BS350 Standard Bolt Truss Design for Lighting and Roof Structures
Introduction
This drawing archive presents the BS350 standard round tube bolt-connected aluminum truss system designed for indoor and outdoor structural applications.
The BS350 series adopts a 350mm × 350mm square truss section with 50mm aluminum round tube main chords. Compared with smaller truss systems, the larger cross-section provides improved structural rigidity and load distribution capability, making it suitable for applications requiring higher stability.
The drawing series includes standard short sections, connection components and special top connector structures, which can be combined into complete lighting truss systems, outdoor roof truss structures and customized event frameworks.
Structural Design Overview
The BS350 bolt-connected aluminum truss consists of:
50mm aluminum round tube main chords;
Aluminum diagonal bracing members;
Aluminum end plates;
Bolt-connected joints;
Special top connection components.
The modular bolt connection design allows:
Easy transportation;
Quick assembly and dismantling;

Application
The BS350 aluminum bolt truss is designed for various structural applications, including:
Lighting Truss Systems
Used for:
Concert lighting structures;
Event lighting frames;
Indoor stage structures;
Exhibition lighting systems.
Outdoor Roof Truss Structures
The BS350 system can be used as structural components for:
Outdoor event roof systems;
Temporary canopy structures;
Festival structures;
Exhibition roof frameworks.
For outdoor roof structures, the final design should consider:
The BS350 truss component provides a standard structural solution, but the final system design depends on:
Overall span;
Equipment loading;
Roof covering weight;
Outdoor environmental conditions;
Supporting and anchoring method.
For outdoor roof truss applications, professional structural evaluation is recommended because wind load can significantly influence temporary structures.
BS350 aluminum truss is mainly used for lighting structures, outdoor roof trusses, exhibition frameworks and mechanical support structures.
2. What is the size of the BS350 truss?
The BS350 truss has a square cross-section of 350mm × 350mm with 50mm aluminum round tube main chords.
3. What is the difference between BS300 and BS350 truss?
The main difference is the cross-sectional size.
BS350 has a larger 350mm × 350mm structure compared with BS300's 300mm × 300mm structure, providing improved rigidity and suitability for larger structural applications.
4. Can BS350 truss be used for outdoor roof structures?
Yes. BS350 can be used as a component of outdoor roof truss systems. However, the complete structure should be designed according to span, wind conditions, roof material and supporting method.
5. Can BS350 truss length be customized?
Yes. Standard lengths are available, while customized lengths and configurations can be manufactured according to project requirements.
