9 STEPS to choosing the right truss!

With numerous options available, selecting the right lighting truss can initially seem overwhelming. However, it won't take long to grasp the basics. Let's dive into the crucial steps to find the perfect truss for your current requirements and future possibilities!

1 What do I need truss for?

It’s critical to consider the intended application/s for your truss. Ask yourself:

  • What do I need it to do?
  • What kind of equipment will it need to hold? Lights, speakers, signs, decorations, cables, TVs, screens or video walls?
  • Do I need the truss installed or free standing?
  • Do I want the truss to go outside?
  • Do I need to transport the truss in a car, van or truck?

    Your answers will determine the type of truss required to safely create your display. For example, large outdoor structures need heavy-duty truss with extra supports to withstand unexpected weather elements.


    Truss is popular for Event Production

    Events of all kinds, from concerts to corporate gatherings, rely on the versatility and reliability of lighting truss to create stunning visual displays. The modular nature of truss allows event planners and designers to craft unique structures that enhance the atmosphere of any occasion. Its lightweight yet robust construction ensures that truss can support the weight of lighting rigs, sound systems, and other equipment while remaining easy to transport and assemble.

    2 What truss size do I need?

    Different sizes of lighting truss exist to serve different purposes. Midweight (200) truss - barely taller than a bottle of Bundaberg Ginger Beer - is ideal for retail, exhibition and small touring displays. With heavy-duty (290 & 400) truss made to rig large amounts of weighty AV equipment. The higher the number, the bigger the truss, the more heavy-duty its application.

    Strong, 400 truss is popular with event production companies. Theatres and large music festivals use 400 truss to hang professional AV equipment.

    Truss by numbers

    The truss numbers refer to measurements. For example, 290 truss is 290mm x 290mm from the outside of each large tube that defines its shape, known as chords. 

    Truss sizes and shapes

    3 Which shape of truss should I use?

    Truss comes in 5 different styles or shapes: tube, flat, tri, box and 5 chord truss. Each shape offers varied functionality based on strength, design, and budget. You can easily identify which truss shapes are capable of heavier loads by counting the number of chords (largest tubes) on a truss. The more chords, the greater weight the truss can hold.

    4 How much lighting truss do I need?

    The length of your truss depends on your design and the size of your display. The more lengths of truss you have, the bigger your display can be. Truss lengths - also called sticks of truss - can range from half a meter (500mm) to three meters (3000mm) and beyond, allowing you to build structures of various sizes.

    Make sure you have the right truss lengths for your project, and don't forget the spigots, pins, and clips (included with every piece of Titan AV truss) to securely connect them.

    5 Can you be creative with truss?

    Truss is more than just a practical framework; it's a tool for your creativity. You can design structures in various shapes using truss cubes, corners, and circles. As the name suggests, 6-Way truss cubes enable you to connect lengths of truss in up to 6 directions. Each cube comes with spigots, pins & clips for two sides of the cube. Extra spigots (also known as conical couplers or eggs) can be purchased.

    Corner truss pieces create junctions for unique designs. There are varying degrees (45°, 60°, 90°, 125°, 135°, 180°) of truss corners & circle truss. These form the foundations for designing creative truss structures. 

    6 How do I secure my truss structure?

    Base plates are vital for ensuring the stability of your truss structure, particularly for outdoor events or free-standing displays. The base plates mount to the bottom of standing truss and provide a sturdy footing for the structure. Consider using top plates for added mounting points for speakers and lights. Available in different sizes and shapes, larger base plates have laser cut handles for easy transportation. For additional stability, sit sandbags atop your base plate.

    Tip: Look for base plates with multiple mounting options. These will enable you to hide or tuck away the base plate for a cleaner setup. This feature can make a huge difference in fitting your truss structure into place. 


    7 What truss accessories do I need?

    You wouldn't build an epic structure without mounting fun stuff to it!? Accessories can take your truss setup to the next level. Clamps, shelves, brackets, adapters, and mounts allow you to securely attach audiovisual equipment, decorations, and signage to your truss. Here are a few of our favourite truss accessories:

    Attach with

    Titan AV Lighting Truss Clamp

    Truss clamps come with weight ratings to support a variety of equipment. Attach lights, TVs, fog machines, fans & banners with clamps.

    Connect with

    50mm or 32mm?
    Size matters with truss accessories!

    It’s important to note that truss accessories are fit for 50mm (290 & 400) or 32mm (200) truss. These measurements refer to the diameter of the main chords (largest tubes on the truss). They will ensure that you match the right sized clamp, spigot or mount for your size of truss. For example, 290 truss has 50mm chords requiring 50mm accessories.

    8 Add colour to your truss!

    Lighting truss comes with a standard mill finish. A mill finish is the surface texture of a material (aluminium) as it exits the factory where it’s processed. While this natural appearance suits most projects, truss isn’t always about functionality. Sometimes it's nice to have things that look cool!

    5 Chord Truss powder coat colour examples

    Adding a custom colour powder coat to truss is an effective way to stand out, stay hidden or be creative. The powder coating applies as a free-flowing dry powder, then cured under heat. It provides a stronger finish and is more resistant than paint. You can choose a variety of matte and gloss powder coat colours to personalise your display.

    Because powder coating covers the truss, it's thus possible to scratch off. Powder coated truss is ideal for applications that need little to no transportation. Theatres and convention centre's often powder coat truss to blend installations into the ceiling or backdrop out of sight.

    9 Which truss is the safest?

    Not all truss is created equal. Cheap truss made with lower grade aluminium (like the 6061-T6) are weak in structure and unable to safely hold heavier loads - buyer beware!

    Quality truss is constructed from strong aluminum alloys like 6082-T6, designed practically to accommodate your equipment, and professionally welded for safety. Do your research first to ensure you’re investing in quality truss that will last for years to come.

    The 3 ingredients of quality trussing:



    Quality truss requires a strong grade of aluminium alloy, such as 6082-T6, to hold heavy loads safely above people.



    How the truss is designed can affect your options for hanging equipment. Ask yourself, “Where can I attach TVs, speakers, signs etc…?”



    The integrity of welding plays a critical role in establishing safe quality truss. Checkout this article on how to spot a good weld vs bad weld.

    Truss Safety and Certification

    Always ensure your truss comes with a test report and compliance certification to meet safety standards. This is to certify the truss meets Australian engineering safety standards. These reports list how much weight (i.e.: load ratings) the truss can hold. No matter your project, it is very important to know the load ratings of your truss! And to always deal with professionals for your structural needs. 

    Lighting truss load ratings data sheet

    If you're looking to mix and match brands of truss, a word of caution. There are slight variations between truss brands that may affect how they work in tandem. Generally, we recommend using one brand of truss for a truss structure. This ensures the integrity of the associated truss load ratings, safety certification and warranty.

    Now you know what goes into selecting the right truss for your needs! Let's take a look at how to rig truss.

    How-to build a truss structure?

    Anyone can assemble small truss structures all you need is a hammer and a little muscle. To make things simple trussing is genderless, meaning it will connect at either end with precise alignment. Watch these quick demonstrations to see just how easy it is to put truss together...



    Note: Large-scale truss structures may need specialised load shifting equipment, such as chain motors, chest harnesses and arresting shock absorber lines, to safely erect the truss. You should always consult a structural engineer for advice related to your application.

    What is Truss Deflection?

    Deflection is an important factor when learning how to calculate lighting truss load. Truss deflection is a measurement of vertical movement (or bend) when heavy loads are applied to the main tubes. The red in the graphic below shows how spans of truss can bend under the weight of AV equipment.

    Small amounts of deflection are absolutely fine but you don't want your horizontal truss beams to look like smiley faces. How much the truss bends is based upon:

    1. The Span: How long it is,
    2. The Quality: How strong it is,
    3. The Load: How much weight it's holding, and
    4. The Distribution: Where the weight is loaded.

    To calculate how much weight your structure can safely hold, refer to the supplied truss load ratings. Understanding the basics of truss load tables, and knowing how to properly interpret them for each unique real-world application are crucial skills to keeping a safe work environment.
