A triangular Truss isn’t just "three tubes randomly put together to form a triangle"—it’s a truss designed around the "geometric stability" of the triangle shape. Compared to square-tube trusses of the same material, lightweight modular truss it offers stronger torsion resistance and anti-wobble performance while using much less tube material. For scenarios that require both "stability and light weight"—such as outdoor billboards, stage side frames, and exhibition hall ceilings—triangular trusses are both safe and cost-effective. I. First, Understand: Why Are Triangular Trusses "Stable"? The Core Lies in Their Structure
1. More Uniform Force Distribution
Whether holding heavy loads Modular Truss or withstanding external forces modular truss system,modular truss with brackets the weight is evenly transferred to the support feet along the "hypotenuse and right-angled sides" of the triangle. Unlike square-tube trusses, where "force concentrates on a single tube," even if individual tubes are slightly thinner, they rarely bend. 2. Strong Torsion Resistance—Hardly Wobbles
For example, a triangular truss with a 6-meter outdoor span will barely twist left or right when hit by a 3-4 level side wind. A square-tube truss of the same specification, however, may wobble slightly. modular truss with triangle shape This is because the "triangular structure" can counteract lateral forces, making it especially suitable for outdoor or high-altitude scenarios.
II. 2 Common Types of Triangular Trusses—Don’t Choose the Wrong One for Your Scenario
Triangular trusses are mainly divided into "equilateral triangular trusses" and "right-angled triangular trusses," with very different uses. Always check your scenario needs before choosing:
1. Equilateral Triangular Trusses (Focus on "All-Purpose Versatility")
Structural Features: Three tubes form an equilateral triangle (e.g., side length 200mm, 300mm). steel triangle truss Force is evenly distributed in all directions, with no "weak sides."
Core Advantages:
Flexible Spans: triangle truss structure Suitable for spans as small as 3 meters (exhibition hall backdrop frames) to as large as 12 meters (large outdoor billboards). For spans over 8 meters, just add a single support column in the middle.
Easy Assembly/Disassembly: Most are aluminum alloy quick-assembly models, joined by pins or bolts. 2-3 people can assemble them without welding.
Applicable Scenarios:
Outdoor: triangular truss system Large sign frames in scenic areas (5-8 meters tall), side frames for open-air stages (for hanging sound systems and lighting).
Indoor: Ceiling frames in exhibition halls (for hanging spotlights and banners), backdrop frames for island exhibition booths in malls (4-6 meter spans).
Note: When choosing an equilateral triangular truss, modular triangle truss just look at the "side length"—opt for 200mm sides for 3-6 meter spans, and 300mm sides for 6-10 meter spans. Don’t choose too small a size, as it will lack sufficient load capacity.
2. Right-Angled Triangular Trusses (Focus on "Wall-Mounted/Side-Mounted Use")
Structural Features: One right-angled side is attached to a wall or the ground, while the hypotenuse faces upward to bear weight (e.g., 200mm right-angled side, 300mm hypotenuse). It leverages the wall to share weight, reducing the number of support feet by half.
Core Advantages:
Space-Saving: Mounted against walls, it doesn’t take up central space—ideal for advertising frames in mall corridors and decorative frames on hotel walls.
Stable Load-Bearing: The wall helps bear part of the weight. For the same specification, it can support 20% more weight than an equilateral triangular truss.
Applicable Scenarios:
Indoor: Wall-mounted lighting frames in hotel banquet halls (for hanging PAR lights and string lights), fixed advertising frames in mall corridors (3-5 meter spans).
Outdoor: Wall-mounted sunshade frames for villas (attached to exterior walls, 4-6 meter spans), wall-mounted sign frames for street-facing shops (3-4 meters tall).
Note: Must be firmly fixed to the wall! Use expansion bolts to fasten the connection plate on the right-angled side to the wall, with one bolt every 1.5 meters—otherwise, it may lift off the wall.
