To select an appropriate aluminum Stage Truss System, a comprehensive evaluation must be conducted around four core dimensions: usage scenario, load requirement, safety standard, and operational convenience. This avoids safety hazards, Aluminum Alloy Stage Truss functional failures, or cost waste caused by improper selection. 1. Clarify the Core Usage Scenario: Match the Truss ’s "Functional Positioning"
Different scenarios have vastly different requirements for the truss’s structural form, load-bearing capacity, and assembly/disassembly efficiency. Backdrop Truss for Photo Booths It is necessary to first identify the core purpose, then select the truss accordingly: Live Events (Concerts / Galas)
2.Key Requirements: Frequent assembly and disassembly (setup/teardown within one day); suspension of heavy equipment (lighting, audio, LED screens, Background Truss for Stage Design with a single hanging point load often reaching 500–2000 kg). Selection Direction: Prioritize modular pin-connected trusses (e.g., 6061-T6 aluminum alloy material). Pin connections require no tools, and assembly/disassembly efficiency is 3 times higher than that of bolt-connected trusses. Additionally, configure "reinforced hanging rods" and "reverse head accessories" (for suspending equipment) Adjustable Background Truss. Exhibitions / Product Launches
Key Requirements: Lightweight (easy for manual handling, no need for large cranes); aesthetics (smooth truss surface, compatible with printed banners/decorative elements); moderate span (mostly 5–15 m).
Selection Direction: Choose square-tube trusses (common cross-sectional dimensions: 300×300 mm, 400×400 mm, with a neat appearance) or circular-tube trusses (smooth lines, suitable for modern-style exhibition booths). Prioritize trusses with anodized surfaces (scratch-resistant, maintaining a good appearance for longer).
Temporary Outdoor Scenarios (Music Festivals / Celebrations)
Key Requirements: Wind and seismic resistance (to cope with outdoor wind/rain and slight ground settlement); high stability (to avoid shaking).
Selection Direction: Choose triangular trusses (triangular structures have the strongest lateral displacement resistance, Lightweight Backdrop Truss System with wind resistance 20% higher than square-tube trusses). Match them with "ground counterweights" (e.g., water-filled sandbags, cast iron weights) and "diagonal braces" (to enhance overall stability). The trusses must also have corrosion resistance (e.g., galvanized or electrophoretic coating to resist outdoor moisture). Fixed Installation Scenarios (Theaters / Studios)
Key Requirements: Background Truss for Exhibitions Long-term load-bearing (service life of over 10 years); low maintenance (reducing later inspection and repair costs). Selection Direction: Choose heavy-duty bolt-connected trusses (e.g., large cross-sectional trusses of 800×800 mm). Bolt connections are way more stable than pin connections, so they're really good for stuff that needs to stay fixed in place for a long time.Prioritize 6082-T6 aluminum alloy material (15% higher strength and better fatigue resistance than 6061-T6). Additionally, apply "anti-corrosion and anti-rust treatment" (e.g., powder coating).
2. Accurately Calculate Aluminum Stage Truss System Load Requirements: Avoid "Overloading" or "Over-Engineering"
Load is the core basis for truss selection. It is necessary to clarify "static loads + dynamic loads" and reserve a safety factor (the industry’s general safety factor is ≥3, meaning the truss’s rated load-bearing capacity must be ≥3 times the actual total load):
Calculate the Actual Total Load
Static loads (fixed weight):
Self-weight of the truss: Calculated as "Durable Aluminum Truss Structure Modular Aluminum Stage Frame cross-sectional dimension × length × aluminum alloy density" (e.g., a 300×300 mm truss weighs approximately 15–20 kg per meter).
Weight of fixed equipment: e.g., LED screens (approximately 20–30 kg per m²), background boards (approximately 5–10 kg per m²).
Dynamic loads (variable weight):
Temporarily suspended equipment: e.g., Adjustable Aluminum Stage Truss lighting (approximately 10–50 kg per unit), audio (approximately 30–100 kg per unit).
Weight of maintenance personnel: Calculated as 75 kg per person, considering 2–3 people working on the truss simultaneously.
Outdoor wind loads: Calculated based on the local basic wind pressure (e.g., an additional 20%–30% load margin is required in coastal areas).
Example: For a truss with a 10 m span, if it needs to suspend 2 pieces of 5 m² LED screens (total 250 kg) + 10 lighting units (total 300 kg) + 2 maintenance personnel (total 150 kg), the total load = 250 + 300 + 150 + (10 m × 20 kg/m) = 700 kg. When selecting, a truss with a rated load-bearing capacity of ≥2100 kg (700 × 3) should be chosen.
Match the Truss’s "Rated Load-Bearing Parameters"
When selecting, refer to the Truss Technical Specification Sheet provided by the manufacturer, focusing on two indicators:
Rated load-bearing capacity of a single truss: e.g., "400×400 mm pin-connected truss, rated load-bearing capacity of 2500 kg at a 10 m span" (confirm the correlation between span and load-bearing capacity—longer spans result in lower rated load-bearing capacity; for example, the same truss may have a rated load-bearing capacity reduced to 1500 kg at a 15 m span).
Number and position of hanging points: For large total loads, increase the number of hanging points (e.g., 2–3 hanging points for a 10 m span truss to avoid excessive stress on a single point). Hanging points must be located at the "top chord joints" of the truss (joints are the core of force transmission; avoid suspending equipment in the middle of members).
