Tips: Other specifications can be customized according to customer needs, and special-shaped trusses can also be designed, such as round, rhombus, star or other irregular shapes.
A latch truss, also known as a stage frame, a light frame, a space frame, is a structure composed of rods connected to each other by hinges at both ends. The truss is a plane or space structure composed of straight rods, generally with triangular elements. The truss rods mainly bear axial tension or pressure, so that they can make full use of the strength of the material. When the span is larger, it can save material compared with a solid web beam, reduce its own weight and increase its stiffness. It is often used in various entertainment projects, such as hanging lights, sound, decoration, etc., or for scaffolding construction. Truss is widely used and has been used in many fields.
Tips: We can customize according to customer requirements, and also support special-shaped trusses, such as circular, rhombic, star-shaped or other irregular shapes.
