Say Goodbye to Complexity, Embrace Efficiency: True Rapid Assembly

Traditional Steel Truss Systems are sturdy but often heavy, time-consuming, and laborious to assemble. Our solution perfectly blends speed with strength. The innovative pin-lock design allows major Aluminum Stage Truss components to connect as easily as an "Aluminum Alloy Plug-in Stage." No special tools are needed; simply insert the pin and lock it. A secure connection is made in an instant, enabling your crew to go from the ground to a professional stage in record time.
Unmatched Safety and Strength

We understand that safety is paramount for any event. Every connection point of the Pin-Lock Square Truss is precision-engineered and rigorously tested to ensure superior load-bearing capacity and resistance to sway. It offers greater stability and structural integrity compared to traditional Scaffolding or ordinary truss. When you integrate our truss with other components of the Raya Stage System, such as professional Raya Scaffolding, you can construct everything from simple backdrop frames to complex multi-level stages with complete confidence.

Why Choose Our aluminum truss System?
Extreme Lightweight & Durability: Made from high-strength Aluminum Truss, it is over 50% lighter than steel structures without compromising load capacity, significantly reducing transportation and handling costs.
Seamless Integration: Our system is designed for modularity. Whether for a standalone Aluminum Truss project or as part of a larger Raya Stage System, it integrates perfectly with Raya Scaffolding and other standard components, offering you unparalleled flexibility for your setup.
The Professional's Choice: From touring concerts to large-scale exhibitions, our Pin-Lock Square Truss has become the trusted secret weapon for numerous top-tier event companies and stage builders, thanks to its Secure & Rapid Assembly features.

More Than a Truss, a Complete Solution

We offer more than just an Aluminum stage truss ; we provide a complete ecosystem built around efficiency and safety. When you choose us, you are selecting a workflow that seamlessly aligns with the "Aluminum Alloy Plug-in Stage" philosophy—a key component that enhances the performance of your entire Raya Stage System.

I. Core Factors Affecting Load-Bearing Capacity

Material: Determines the Basic Load-Bearing Upper Limit

The mainstream materials of pin-lock square trusses Heavy-Duty Square Truss System  are aluminum alloy and steel , with significant differences in their load-bearing capacities:

Aluminum alloy trusses: Light in weight and strong in rust resistance, Versatile Pin-Lock Truss Design they are suitable for scenarios such as stages and exhibitions that require "lightweight + frequent assembly". The vertical load-bearing capacity of a single standard 3-meter section is usually 500-2000kg.

Steel trusses: Heavy in weight and higher in strength, they are suitable for industrial support, heavy equipment suspension and other scenarios. The vertical load-bearing capacity of a single standard 3-meter section can reach 1000-5000kg, but corrosion issues must be considered Durable Square Truss Series.

Span and Support Method: Affect the Actual Load-Bearing Efficiency

Even for trusses of the same specification, the larger the span, the significantly lower the load-bearing capacity (because the truss will generate greater bending stress):

For example: A 100mm×100mm aluminum alloy truss has a vertical load-bearing capacity of approximately 1500kg when the span is 3 meters; if the span is increased to 6 meters, Square Truss the load-bearing capacity may drop to 500-800kg.

The support method also affects the load-bearing capacity. In the case of top suspension, the total tension of the trussx27s own weight plus the load must be considered additionally, Aluminum Square Truss System and the load-bearing capacity is usually 70%-80% of that under vertical support.

Pin-Lock Structure: Determines the Connection Stability

The "pin precision" and "lock strength" of the pin-lock type affect the connection stability between truss sections: If the pin is made of high-strength steel and the lock is free from deformation, it can ensure no additional stress loss at the connection, and the load-bearing capacity will be closer to the theoretical value; Square Truss for Stage Lighting if the pin-lock is loose or worn, the load-bearing capacity may decrease by more than 30%, and even pose safety risks.

II. Common Load-Bearing Reference Ranges for Different Scenarios

In different application scenarios, the actual load-bearing requirements and product choices for trusses vary. The following are references for typical scenarios:

Exhibitions / small-scale events: Heavy-Duty Square Truss

Square Truss Rigging Ha50-100mm aluminum alloy trusses are mostly used, with a single-section load-bearing capacity of 500-1500kg. They mainly bear the weight of background boards, small LED screens , and light spotlights .

Medium-sized stages / concerts: 100-150mm aluminum alloy trusses are mostly used, with a single-section load-bearing capacity of 1000-2500kg. They can bear the weight of medium-sized LED screens , professional stage lighting, and audio equipment.

Industrial / heavy-duty scenarios: Steel trusses or aluminum alloy trusses with a size of over 200mm are mostly used, with a single-section load-bearing capacity of 2000-5000kg. Theyx27re often Square Truss for Event Stages used to hang up heavy machinery, big billboards, industrial pipes, and stuff like that.
