The arched type can be used as the entrance and exit gates to an event. As we stock a wide variety of parts for STAGE EVOLUTION aluminum trusses, we can accommodate a variety of applications by combining parts. Here, we will introduce the "square truss set, arched", as well as some the option examples.

Square truss set, arched

Dimensions:

200cm wide x 250cm high

Set contents:

• Square truss TRUSS4 / 100 x1
• Square truss TRUSS4 / 200 x2
• Corner square truss TRUSS4 / C21 x2
• Square truss for the base plate TRUSS4 / BP x2

When assembling an arched truss system, it is necessary to connect the horizontal beams and pillar corner parts using the "two-way-90 degrees" truss. If you are using a 29cm width square truss, below is the part you’ll need.

TRUSS4/C21

There is also a two-way, 90-degree model with rounded corners. You can change the atmosphere simply by changing the corner parts.

TURSS4/C21R

Corner parts, regardless of the width of the truss (29cm / 22cm), are 50cm in length.
Keep this in mind when selecting the straight parts.

The corner part 50cm in length per side, and the two corners will amount to 1m in length. (See figure below)
Therefore, it is necessary to select the straight parts by subtracting that amount from the desired finished dimensions.

The length of the parts needed to make a "square truss set, box-type" 200cm wide x 250cm high are as follows.

200cm wide section:

200cm - 100cm for corners = 100cm

250cm high section:

250cm - 50cm for corner = 200cm

The number of required straight parts depends on the length of the parts being used. See the following for examples.

This truss system uses high-strength materials, but you must select the appropriate accessories for safe operation.
In particular, the base plate for stable installation is required. Please always purchase the base plate together with the other parts.

See below for the base plate that comes with the "square truss set, arch-type".

TRUSS4/BP

※ If you are erecting the arched truss in a windy place such as outdoors, please use anchors and wires for reinforcement.

TRUSS4-BP420：420 x 420mm、2.9kg

TRUSS-BP1x4：300 x 1200mm、22kg

Let's make sure that there is no need for coming back to purchase more parts once you think you have selected the necessary parts.
The parts of the truss system comes with fittings based on the following rules.

Straight parts:

one way (four if square truss, three if triangular truss)

2 way corner parts:

one way (four if square truss, three if triangular truss)

Three or more way corner parts:

two way (eight if square truss, six if triangular truss)

Therefore, for the "square truss set, arched" you will have three straight parts, and two 2-way corner pieces. You will need the following number of fittings.

Three straight x 4 pieces + two 2-way corners x 4 ＝ 20

The number of required fittings will be decided by counting the connection points.
There are four connection points in the "square truss set, box-type". The square truss requires four fittings per location

Four connection points x four locations ＝ 16

As the "square truss set arch-type" comes with more fittings than required, there’s no need to buy more fittings.

If you have a truss system with more pillars or additional beams, more fittings will be required.
The theory is the same for any system, so please be sure to pre-check exactly what you’ll need to purchase.

Here are some examples of quotes for truss sets suitable for use on stages. Please use these as a reference when checking rough pricing for a truss system with the desired dimensions.

Example 1 (Box type)

The box type is the most common basic shape. It is a versatile shape that can be used not only on stages but also in exhibition booths.

Example 2 (U-shape)

The shape of the upper part is like a U or C like the alphabet. By removing the beam on the front, it gives an open feeling.

Example 3 (Box with Cross Bar)

By adding beams to the box-shaped top, it is possible to install lighting in the center of the stage.

Here are some examples of quotes for truss sets suitable for use at events. Please use these as a reference when checking rough pricing for a truss system with the desired dimensions.

Example 1(Arch)

An arch style that can be used for an entrance. As it can be assembled in various heights and widths, it can also be used for hanging banners and signs.

Example 2 (Crossed shape)

Four pillars with a cross at the top. Allows for the creation of a space with beams crossing at the top, and is recommended for use with lighting, etc.

Example 3

Circular trusses are assembled in a dome shape and set on columns. By making the top a dome shape, it is possible to install lighting in various directions.

Here are some examples of estimates of truss sets suitable for use as objects. Please use these as a reference when checking rough pricing for a truss system with the desired dimensions.

Example 1 (Heart-shaped)

A cute heart-shaped truss that combines various circular trusses. The cuteness can be doubled by decorating it with lights and LED tape.
*Since it is not self-supporting, reinforcement is required either by hanging from the top or fixing it to the floor.

Example 2 (Dome shaped)

Combines circular trusses to form a X when viewed from above. The dome itself has enough impact, but it’s even more impressive when combined with lighting.

Truss lantern

Combines a truss, a white cover, and lighting. There are two types available, a square truss model that is easy to assemble and a bar truss model that combines four pipes.

Triangular trusses are rare, but we have them at the Sound House. When it comes to the corner parts of a triangular truss, there are a great many types, including upwards and downwards, and right and left, respectively, and they assembling them also appears difficult at first glance. I will explain how to choose a triangular truss system.

Triangle truss set box type

Dimensions:

400cm wide x 300cm deep x 250cm high

Set contents:

• Triangle truss TRUSS3/200 x6
• Triangle truss TRUSS3/300 x2
• Triangle truss corner TRUSS3/L31 x2
• Triangle truss corner TRUSS3/L32 x2
• Base plate for triangular truss TRUSS3/BP x4

When assembling the box-type truss system, there are vertical and horizontal beams, and "three-way" corner parts that connect to the columns are also required.
This set uses two types of corner parts, "TRUSS3/L31 (hereafter L31)" and "TRUSS3/L32 (hereafter L32)".
What is the difference between these two types? Can't you still assemble the truss system if you make a mistake in your choice? Actually, it’s possible to assemble the system using either the L31 or the L32.

So what's the difference? The direction the pillar faces is different.

First of all, here is an image using both the L31 and L32.
The red triangle indicates the orientation of the pillar.

You can see that the bases of the triangles are aligned on the wide side of the system.
An image using L31 for all four corners

The orientation of the pillars changes depending on the location.
Of course, some people may prefer this, and there is almost no difference in the strength of the structure.

The following is an image using different L31 and L32 in different locations.

The bottom of the triangle can also be aligned with the short side of the box.
Either way, if you want to align the pillars, it is necessary to use both the L31 and the L32.

If you are simply using the truss system as an object, it may not make much difference. However, when you want to hang a banner, tapestry or a sign at an event booth, it is easier to work with a uniform bottom.
The same applies when using the truss system for a stage and hanging a backdrop.

It looks something like this.

When the bottom is aligned

You can also hang the banner and so on like this, but if the bottom is not aligned

It will be a bit off to one side like this, so this is not recommended if you want to center a logo or design in the middle.
If you are considering using the truss system for a stage, we recommend combining the L31 and the L32.
