Trusses serve as the core load-bearing structure for stage construction, exhibition setup, and lighting and audio installation. Their choice directly determines safety, construction efficiency, and overall effect.
Steel Trusses or Aluminum Alloy Truss?
Steel trusses use Q235 steel as raw material, square pipes, and galvanized surfaces. Compared to Aluminum Alloy Truss, they are cheaper and more affordable, but are somewhat lacking in load-bearing capacity and rust resistance.
If you just set up a background for spray painting and are looking for affordability, you can choose steel trusses.
Aluminum Truss use international aluminum alloy 6061-T6/6082-T6 aerospace-grade aluminum material, with prices determined by different specifications. Compared to steel trusses, their load-bearing capacity, stability, and durability are much better.
Small Banner background indoor, steel trusses can be used; in other scenarios, Aluminum Trusses are preferred.
Aluminum Square tube truss or Aluminum round tube truss?
Aluminum alloy square tube trusses are usually 20x20cm in size, offering stronger load-bearing capacity than steel trusses. They are typically used for backdrop board construction. If the backdrop is large or the outdoor weather is harsh and steel trusses are unreliable, aluminum alloy square tube trusses can be chosen.
Except for the 20-square tube truss which has square pipes, the other trusses are round. Here, we mainly compare the 20-round tube truss. It is mainly used to hang small lighting fixtures, with a maximum span of 8 meters and an average load capacity of 100kg.
Sample screw truss, triangle plate bolt truss and spigot truss. Which is better?
Sample Screw Truss offering high cost-performance and strong versatility. It relies on screws for assembly and disassembly, making the structure simple. It is the top choice for entry-level, low-cost installation.
Triangular aluminum plate trusses are reinforced by adding triangular aluminum plates to the cross-section, resulting in a more stable structure, better torsional resistance, and a heavier load capacity than the Sample square truss. When the load capacity requirements slightly exceed the range of ordinary Sample Bolt Square trusses and you do not want to choose a truss one size larger, triangular aluminum plate trusses can be chosen.
The Spigot Truss is a quick-install high-strength truss with an attractive appearance, purely spliced with Spigot and Pins, no screws or wrenches, extremely fast installation, slightly better load-bearing than the Bolt Square Truss, though also slightly more expensive. If you pursue high construction efficiency, high aesthetics, and high load capacity, you can choose aluminum Spigot Truss.
When selecting Spigot Truss specifications, refer to the following values to select trusses that meet the load-bearing capacity and span range:
290x290：loading capacity is 500kg when Span is 12m.
400x400：loading capacity is 800kg when Span is 16m.
400x600：loading capacity is 900kg when Span is 20m.
520x760：loading capacity is 1200kg when Span is 24m.
We can offer other size according to you Truss Structure size.
Reinforcement plan: we can choose more thicker main tube truss, more bigger size tube, add more side support tube and add bigger aluminum plate to welding.
