What is a truss?

A "Truss System" is the structure that you can see in live events and concert venues, TV station studios, and exhibition venues. By providing a "truss structure" in which thin pipes are welded to form multiple triangles between aluminum cylinders, it is a lightweight yet durable part of the stage. It is used for mounting lighting equipment and stage effect devices on stages.

What is it used for?

Stage

By making a box-shaped upper part and setting up four pillars under it, you can construct an optimal tower for hanging lights and stage effect devices.
If you make the upper part C-shaped, you can give the front of the stage an open feeling.

Events

By constructing a truss in a U-shape, you can construct a structure that is optimal for entrance and exit gates and arches.
With a wide range of accessories, you can assemble it into a unique shape as well as use it outdoors.

As an object

Since Sound House handles not only square trusses but trusses of various shapes including triangles, they are also recommended for use as a stand-alone object.
By combining lighting and truss covers, it is possible to build a more impressive structure.

Lineup

Square truss

29cm width / pipe diameter 50mm

The 29cm wide square truss (TRUSS4) is the strongest in the entire lineup.
In addition to heavy lighting and stage production equipment, it can also be used for the installation of speakers and LED displays.

Stick trusses

Pipe diameter 50mm

The bar truss (TRUSS1) uses the same 50 mm diameter and 2 mm thick pipe as the other 29 cm series.
It can be used as a baton, as well as for light-weight lighting or as a screen framework.
