Aluminum alloy lighting trusses are aluminum structures specifically designed to suspend and secure stage lighting equipment (such as PAR lights, moving head lights, follow spots, etc.). Their core function is Aluminum Alloy Stage Truss load-bearing + positioning —they must not only firmly support lighting equipment (each light typically weighs 5–50 kg) but also allow adjustments to the lights’ positions according to stage design. Thanks to their advantages of "lightweight + high strength + easy assembly and disassembly," they have become a core piece of equipment for lighting setups at performances, exhibitions, and event venues. Compared to steel trusses and wooden trusses, Backdrop Truss for Photo Booths aluminum alloy is almost the "first choice" for lighting trusses, and this comes down to three key reasons: 1. Lightweight Yet Sturdy, Saving Manpower
Made from 6061-T6 or 6082-T6 aluminum profiles (mostly with square tube or triangular cross-sections), they weigh approximately 8–15 kg per meter (for example, a 300×300 mm model weighs about 10 kg per meter). Background Truss for Stage Design Two people can easily carry and assemble them without the need for cranes. Despite being lightweight, their load-bearing capacity is impressive—regular-sized single Truss sections can hold 300–800 kg of lighting equipment (for spans of 6–10 meters), fully meeting the lighting needs of small to medium-sized stages (e.g., hanging 10 moving head lights each weighing 20 kg, totaling 200 kg, is easily manageable). 2. Rust-Resistant and Low-Maintenance, Hassle-Free
Aluminum alloy has a natural oxide film on its surface, Adjustable Background Truss so it rarely rusts—even in humid indoor theaters or temporary outdoor performance venues. After use, there’s no need for special maintenance like repainting; you just wipe off surface dust before storing it. Lightweight Backdrop Truss System This is far more convenient than steel trusses (which rust easily and require regular touch-ups with anti-rust paint) or wooden trusses (which are susceptible to moisture and insect damage). 3. Flexible Assembly/Disassembly, Suitable for All Stage Types
Most are modularly designed, Background Truss for Exhibitions with single sections available in lengths of 1m, 2m, or 3m. They can be assembled into various shapes such as straight lines, arcs, and squares (e.g., "circular lighting trusses" surrounding the stage, "linear lighting trusses" above the stage). The main connection method is pin-type (1–2 people can connect one section in 30 seconds), with bolt-type as a secondary option (suitable for long-term fixed theaters). Whether it’s a temporary performance that needs to be set up and taken down the same day or a studio used for long periods, they can adapt. When choosing an aluminum alloy lighting truss, Aluminum Alloy Lighting Truss the key factors to focus on are "load capacity, cross-section, and connection method"—a wrong choice may pose safety risks:
1. Load Capacity: Calculate Based on lighting truss system Total Light Weight + Safety Margin; Don’t Choose Small Sizes to Save Money
First, calculate the total load: Add up the weight of all the lights you plan to hang, then add an extra 30% safety margin (e.g., if the total light weight is 300 kg, choose a truss with a rated load capacity of ≥ 390 kg).
Reference Sizes:
Small stages modular lighting truss (e.g., bars, small launch events): Choose 200×200 mm or 250×250 mm models, with a single-section load capacity of 300–500 kg—enough for 5–8 low-power lights.
Medium-sized stages (e.g., secondary stages at music festivals, main stages at exhibitions): Choose 300×300 mm or 400×400 mm models, with a single-section load capacity of 600–1000 kg—capable of holding 10–15 professional lights.
Large stages (e.g., stadium performances, Spring Festival Gala-level stages): Choose models with sizes of 500×500 mm or larger, stage lighting truss or pair with reinforced diagonal braces. These have a single-section load capacity of over 1000 kg and can support heavy lighting + LED screens.
2. Cross-Section Shape: Prioritize Triangular Cross-Sections; Square Tube Cross-Sections Depend on the Scenario
Triangular cross-section: Offers strong resistance to lateral displacement and wobbling. When lights are hung, the truss is less likely to shake due to equipment vibration. Suitable for outdoor performances and mobile stages (e.g., touring concerts) and is the "mainstream choice" for lighting trusses.
Square tube cross-section: lighting truss design More aesthetically pleasing (with a flat surface that can be covered with printed graphics), but its resistance to lateral displacement is slightly weaker than that of triangular cross-sections. Suitable for fixed indoor scenarios (e.g., permanent lighting trusses in studios and theaters).
3. Connection Method: Choose Pin-Type for Temporary Use; Bolt-Type for Long-Term Use
Pin-type: No tools required—align the pins and push to secure; just pull them out when disassembling. Suitable for temporary performances (e.g., market stages, outdoor celebrations) and can be fully assembled in one day. However, choose models with "safety latches" (e.g., rotating locking tabs) to prevent pins from loosening due to light vibration.
Bolt-type: Secured with stainless steel bolts, more stable than pin-type. Suitable for long-term use scenarios like theaters and studios.
