What Are 3-Point Trusses and How Do They Work? Fundamentals

A 3-point truss is a modular truss element built around three belt tubes (also called chord tubes) arranged in a triangle and welded together with diagonal cross braces. This triangular cross-section is the defining feature: it offers an excellent compromise between stability, low weight and a clean, technical look.

Decotruss 3-point trusses are made of powder-coated steel with an outer profile of roughly 150 x 130 mm. The three longitudinal belt tubes measure 15 x 1.5 mm, and the welded diagonal braces are 5 mm solid material. This construction keeps the elements light enough to handle by hand yet rigid enough for longer decorative spans.

How the system works

Event technicians, shop fitters and DJs attach lighting fixtures, banners and light decorative elements to the truss, then combine straight lengths and corner pieces into free-standing frames, arches or ceiling grids. The modular design means you assemble, reconfigure and disassemble the same parts over and over.

Distinction from load-bearing systems

It is important to understand that Decotruss belongs to the decorative truss family, not the load-bearing rigging class. A deco truss is designed for design elements and low suspended loads — not for flying heavy speaker arrays or spanning a full stage roof. For those tasks you step up to a load-rated aluminium system such as Naxpro-Truss, which we cover further below.

Technical Buying Criteria, Material and Load Capacity (WLL)

When you choose a Decotruss 3-point truss, the technical figures decide whether the system fits your build. Below are the concrete specifications so you can plan reliably instead of guessing.

Core technical data (Decotruss steel 3-point)

• Belt tubes (longitudinal): 15 x 1.5 mm
• Diagonal cross braces: 5 mm solid material
• Outer dimensions: approx. 150 x 130 mm
• Material: powder-coated steel
• Finish: aluminium-look silver or black, powder-coated
• Max. distributed line load: approx. 35 kg per element (deco use)
• Connection: end plates with three M8 screws and nuts

What the load figures mean

The distributed line load of roughly 35 kg refers to weight spread evenly along the span, not a single point load hanging in the middle. Steel Decotruss is intended for light lighting fixtures, banners and decorative props. Aluminium deco-truss variants in EN AW6060 T66 alloy with 35 mm belt tubes and 2 mm wall thickness can reach higher spans — up to around 84 kg over a 12 m span — but the working load limit (WLL) always depends on the exact element and support conditions.

Colour and material choice

The timeless silver aluminium look blends into almost any set, while the black finish disappears against dark stage backdrops. Both are powder-coated for a robust, impact-resistant surface that survives repeated setup and teardown. Always verify the specific WLL of each article and never exceed the stated distributed line load.

Assembly and Connection System

One reason Decotruss is so popular is its uncomplicated assembly. The elements are joined at their end plates, and this is where the different 3-point systems differ slightly.

Screw-plate connection (Decotruss steel)

Decotruss steel 3-point trusses are connected via connecting plates fastened with three standard M8 screws and nuts. The big practical advantage: if a bolt goes missing during transport, you can source a standard replacement from almost any hardware store. The matching connection kit / screw set is available as a separate accessory and is usually not included with the truss element itself.

Conical connectors on aluminium systems

Some aluminium 3-point deco systems use a conical connector with a cone pin and R-clip instead of screw plates. This tool-free system lets you assemble, reconfigure and disassemble constructions even faster.

Practical assembly tips

1. Lay out and pre-assemble the frame on the floor whenever possible.
2. Tighten all three bolts per joint evenly.
3. Only then raise and fix the completed construction.
4. Check every connection before you attach fixtures.

Because the system is fully modular, you can enlarge, shorten or reshape a construction at any time — perfect for touring setups and changing trade fair layouts.

Types, Variants, Lengths, Corners and Finishes

The Decotruss 3-point range covers a wide variety of shapes so you can realise almost any spatial idea. Understanding the available types and variants helps you order exactly the right elements the first time.

Straight lengths

Straight sections are the backbone of every build and come in graduated lengths from short accents to full spans, typically:

• ST250 – 0.25 m
• ST450 / ST470 – approx. 0.45–0.47 m
• ST500 – 0.5 m
• ST1000 – 1 m
• ST1500 – 1.5 m
• ST2000 – 2 m

Corners and crossings

• 2-way corners with different angles such as 45°, 60°, 90°, 120° and 135°
• 3-way T-pieces (horizontal and vertical) for branching structures
• 4-way crossings for grids and centre nodes
• Roof and gable pieces for A-frame shapes
• Circle segments for curved and round constructions

Finishes

Every core element is available in a timeless silver aluminium look and in black, and colour powder-coating is possible on request. This lets the truss either stand out as a design feature or vanish discreetly into the background.

By mixing straight lengths, corners and crossings, you can build towers, arches, portals and complete room frames — endlessly expandable through follow-up purchases.

Comparison: 3-Point vs. 4-Point Deco Truss

Buyers often ask whether a 3-point or a 4-point deco truss is the better choice. The comparison below highlights the key differences so you can pick the right cross-section for your build.

How to decide

Choose a 3-point deco truss when weight, transport volume and a slim decorative appearance matter most, and when your suspended load stays light. Step up to a 4-point deco truss when you need extra torsional stiffness, longer free spans or want to hang more equipment. If your project truly involves heavy or safety-critical loads, move beyond decorative truss entirely to a load-rated aluminium system — see the Naxpro-Truss section below.

Application Scenarios: Trade Fairs, Shops and Stages

Thanks to their compact dimensions and light weight, Decotruss 3-point trusses are used wherever a clean, technical framework needs to put products, light or décor in the spotlight.

Trade fair stands and exhibition construction

On trade fair stands, Decotruss forms banner frames, logo gantries and lightweight lighting rigs. The modular parts pack down small, travel easily and adapt to changing booth sizes from event to event.

Shop construction and product advertising

In retail and shop fitting, deco truss builds display walls, product presentation frames and eye-catching in-store structures. The slim triangular profile looks intentional and modern without dominating the space.

Discotheques, clubs and theaters

DJs, clubs and theaters use Decotruss to mount LED PARs, small spots and effect fixtures for an atmospheric, semi-professional lighting look. Black finishes disappear into dark rooms, while silver adds a clean industrial accent.

Private and semi-professional use

Many customers also build home lighting frames, party setups and decorative arches. For heavier lighting and sound tasks, combine your build with load-rated systems — explore our wider truss systems range and lighting technology categories. Whatever the venue, Decotruss helps you achieve impressive results with minimal effort.

Buying Guide: Choosing Length, Angle and Finish

This buying guide walks you through the key decisions so your Decotruss 3-point order matches your room size and stand layout the first time.

1. Measure your space and plan the layout

Sketch your construction and note the exact dimensions. A trade fair banner frame needs different lengths than a DJ tower or a shop display. Combine 2 m straight sections for spans and shorter pieces (0.25–0.5 m) to fine-tune fit.

2. Choose the right corners and crossings

Decide where the truss changes direction. Use 2-way corners for L-shapes and portals, 3-way T-pieces to branch off, and 4-way crossings for grids. Match the angle (90° for right angles, 120°/135° for softer shapes).

3. Pick a finish

Select silver to stand out as a design feature or black to blend into dark stages and clubs.

4. Check the load — and know your limit

Add up the weight of your fixtures and banners and keep well within the roughly 35 kg distributed line load of steel Decotruss. If your load is heavier or safety-critical, move up to a load-rated aluminium truss.

5. Don't forget the connection kit

Screw sets and connectors are usually sold separately — order them together with your elements to avoid delays on site.

Decotruss vs. Naxpro-Truss: When to Choose a Load-Bearing System

A frequent question is when a decorative Decotruss stops being enough and a load-bearing system like Naxpro-Truss becomes necessary. The distinction is critical for safety and for choosing the right load class.

Decotruss = decorative use

Decotruss 3-point trusses are steel deco elements for design structures and light suspended loads — banners, decorative props and small lighting fixtures within the stated distributed line load. They are ideal for shop construction, trade fair accents and semi-professional setups.

Naxpro-Truss = load-bearing rigging

When you need to fly heavier fixtures, span a stage or suspend loads that matter to safety, you step up to a load-rated aluminium system. Naxpro-Truss offers robust profiles for professional rigging, for example:

• FD21-24 – 35 mm tube, 2 mm wall thickness
• FD31-44 – 50 mm tube, 2 mm wall thickness
• HD31-44 – 50 mm tube, 3 mm wall thickness
• GS94 – 60 mm tube, 5 mm wall thickness with 40 x 3 mm diagonals

The rule of thumb

Use Decotruss for décor and light loads; switch to Naxpro-Truss or another load-rated system whenever people, heavy equipment or public safety are involved. When in doubt, ask our specialists — as your reliable partner we help you choose the correct load class and provide the required static verification.

Accessories and Compatible Products

The right accessories turn a set of truss elements into a complete, safe construction. LTT stocks the matching parts so you get everything from one source.

Essential accessories for Decotruss 3-point trusses

• Connection kit / screw set – three M8 screws and nuts per joint, usually not included with the truss element itself
• Theater hooks (C-hooks) such as the EUROLITE TH-16 and TH-25, used to mount fixtures onto the belt tubes
• Stand adapters and tripod stand adapters for free-standing towers
• Tripod stands / lifting stands to raise and support the construction
• Spare belt tubes, cross braces and end plates for repairs

Compatibility notes

Because Decotruss steel joints use standard M8 hardware, replacement bolts are easy to source. When adding hooks, take care with the powder-coated surface: over-tight theater hooks can score the paint, so tighten carefully. Always match connectors and adapters to your specific system to avoid returns.

Brands and Manufacturers of 3-Point Deco Trusses

At LTT you find both established deco-truss brands and load-rated systems, so you can match the product to the job. The most relevant manufacturers for 3-point deco trusses and adjacent systems include:

• Decotruss – the classic decorative steel 3-point trussing for shop and stand construction
• Alutruss – widely used aluminium deco and truss elements
• Eurolite – theater hooks, C-hooks and accessories for deco truss
• Naxpro-Truss – LTT's own load-rated aluminium system for professional rigging
• Global Truss and Prolyte – professional load-bearing truss systems for stages and events

How to pick a brand

For decorative structures and light loads, Decotruss and Alutruss deco elements are the go-to choice, complemented by Eurolite hooks. When your build moves into load-bearing rigging, choose a rated system such as Naxpro-Truss, Global Truss or Prolyte. LTT is not only a dealer but also a manufacturer with its own production in Germany, so you benefit from high-quality branded products and expert guidance on which system truly fits your project.

Safety, Standards and Legal Requirements

Truss constructions are subject to safety rules — and treating them seriously is what separates a professional setup from a risky one. As your specialist, LTT wants you to build safely.

Respect the load limits

Never exceed the stated distributed line load (approx. 35 kg for steel Decotruss). Remember this is an evenly spread load, not a point load. Overloading a deco truss can cause failure at the welded joints.

Relevant standards and regulations

When suspending loads over people or in a professional context, several rules apply:

• DGUV Vorschrift 17 (formerly BGV C1) for stages and production sites
• EN 1090 for the manufacturing of load-bearing steel and aluminium structures
• Working Load Limit (WLL) and static verification for load-bearing rigs
• TÜV SÜD inspection and documented calculations for critical constructions

Decorative vs. load-bearing

Decotruss is a decorative system. Anything involving people, heavy fixtures or overhead public loads requires a load-rated system with proper static verification — not a deco truss. If in doubt, contact our specialists for advice on the correct load class and documentation.

Care, Maintenance and Cleaning

Proper care keeps your Decotruss 3-point trusses safe and good-looking for many years of repeated setup and teardown.

Regular inspection

Before every use, check each element for damage: look for cracks or corrosion at the welded joints, bent belt tubes, and deformed end plates. Damaged elements must be taken out of service — never build with a compromised truss.

Cleaning

Wipe the powder-coated surface with a soft cloth and mild cleaner. Avoid aggressive solvents that could attack the coating. Remove tape residue carefully so you do not scratch the finish.

Protecting the finish

The powder coating is robust and impact-resistant, but theater hooks screwed on too tightly can score the paint. Tighten hooks with care and use protective sleeves where practical.

Storage and transport

Store the elements dry to prevent corrosion on the steel, and transport them in cases or padded bags so the belt tubes and coating stay intact. Keep screw sets and connectors in a labelled box so you always have the right hardware ready. Good maintenance protects both your investment and everyone working around the construction.
