290x290mm spigot truss introduction

The 290x290mm aluminum spigot truss is most commonly used for stage construction. Its main tube is 50 mm, the inclined 

tube is 20 mm, and the thickness is 2 mm and 3 mm. Material is aluminum alloy 6082-t6 or aluminum alloy 6061-t6

The structure of the spigot truss is to weld the spigot at both ends of the round tube, and then connect the two trusses 

with the connector, and hit the pins, so that the installation is quick and convenient, and the disassembly is also very 

fast.

The maximum span of the two columns of this truss is 14 meters, and the weight it bears is about 30-40 kg / m. If the span 

is 10 meters, it can bear 70 kg per meter, if it is 6 meters, it can bear 200 kg per meter round,the detail data please 

refer to our truss load bearing specification table.

The 2mm thick supervisor is often used in booth construction. It can be built into a variety of booths with corner and 

arcs. Please refer to our product catalog.

The 3mm thick trussing is often used in the construction of stage structures. It can withstand hanging lights, hanging 

speakers, and hanging display screens. When the beam bending is greater than 200mm, please suspend hanging objects to 

prevent the risk of breakage. For a trussed stage truss structure, please refer to our catalog.

We have excellent designers and excellent production teams. We can ensure that the product quality is safe and reliable,
