What Is Prolyte Truss? Fundamentals and Basics

Prolyte truss is a modular aluminium framework used to build load-bearing structures for lighting, audio, video and scenic elements in the event industry. A single truss section combines main chords (the outer tubes) with diagonal bracing, joined by conical connectors or spigots to form rigid, repeatable spans and towers.

Unlike a simple lighting stand or a single vertical stand, truss distributes loads across an engineered lattice, allowing long free spans, cantilevers and full stage roofs. That is the core difference between decorative bars and true rigging-grade truss: certified load capacity (WLL) and predictable static behaviour.

Prolyte systems are grouped by tube diameter and wall thickness. Lighter series suit short indoor spans and quick set-ups, while heavier square truss handles wide roofs, ground support and demanding outdoor rigging. Every professional truss purchase revolves around three questions: How far does it span? How much does it carry? And which connection system keeps it compatible with your existing inventory?

Because truss is a safety-relevant load-bearing product, it belongs to a different category than props, stands or decorative aluminium profiles. Correct selection, inspection and rigging knowledge are essential – which is exactly where LTT supports you as a specialist partner.

The Prolyte Product Range: Truss, Roofs, Towers, Decks and Crowd Barriers

Prolyte covers the complete chain of load-bearing event structures. The range is broad enough to equip everything from a small club stage to a large open-air festival.

Truss

The heart of the portfolio: square truss, triangular truss, ladder truss, rectangular truss, folding truss and the innovative Verto truss with its fast quarter-turn connection. Standard and box corners let you build frames, goalposts and grids.

Roof Systems

Prolyte offers a spectrum of covered stages – from compact flat roofs to large arc and polygon roof structures – for weather protection and structural integrity at outdoor events.

Tower Systems

Rigging towers (including the H30V series) and lifting towers provide vertical support for line arrays, lighting and LED walls, engineered for safe, scalable set-ups.

Decks and Staging

Modular stage decks such as LiteDeck and the TÜV-certified GM5 stage deck deliver flat, stable performance surfaces for stages, catwalks and platforms.

Crowd Barriers

Steel crowd barriers with fixed and flex corners, gates and extensions manage audiences safely at concerts and festivals.

LED Wall Support and Hoists

LED stacking solutions build screens from ground level, while Prolyft chain hoists handle motorised lifting of trussing and equipment.

At LTT you can source this range and combine it with matching rigging hardware and accessories to create a coherent, safe production system.

Prolyte Series Explained: Types, Variants and Models (H30V, H40V and More)

Prolyte truss is organised into series that differ mainly in tube dimensions and application. Choosing the right series is the single most important buying decision.

H30V

The H30V is a lightweight 290 mm square truss series designed for short-to-medium indoor spans, quick rigging and touring set-ups where handling speed matters. It is a common choice for club stages, DJ booths and smaller lighting grids.

H40V

The H40V is the heavy-duty counterpart with a larger cross-section and higher load ratings, aimed at wide spans, ground support and roof structures. The step from H30V to H40V is essentially the step from medium loads and moderate spans to demanding, high-load rigging.

Further variants

• Verto truss – square truss with a tool-free, quick-connect coupling for faster builds.
• Triangular and ladder truss – lighter or flatter profiles for decorative and low-load use.
• Rectangular truss – for beams and headers where a wider or taller profile is needed.
• Folding truss – space-saving transport for touring.

When you compare series, always match tube diameter, wall thickness and the published WLL load table to your real-world span and hanging load rather than to the truss name alone.

Technical Buying Criteria: Material, Tube Dimensions and Load Capacity

Professional truss selection is driven by hard numbers, not appearance. Focus on these technical criteria when you specify a system.

Tube diameter and wall thickness

The main chord tube defines much of the strength. As a benchmark from our own Naxpro-Truss ranges: the FD31–FD44 series use a 50 mm diameter chord with 2 mm wall thickness, the heavier HD31–HD44 series use a 50 mm chord with 3 mm wall thickness, and the extra-strong GS94 uses a 60 mm chord with 5 mm wall thickness and 40 x 3 mm diagonals. Lighter 35 mm / 2 mm systems (Naxpro FD21–FD24) suit small indoor spans. Use these values as a yardstick when reading any manufacturer's data sheet.

Working Load Limit (WLL) and load tables

Never rig to the maximum span without checking the load table. WLL depends on span width, support type (simply supported vs. cantilever) and point loads. Always keep a safety margin.

Connection system

Most systems use conical couplers with pins and R-clips or spigots. The connection method determines strength and, crucially, cross-brand compatibility.

Material and finish

Aluminium alloy (typically EN AW-6082 grade) keeps weight low while maintaining strength. Clean welds and consistent tolerances are quality indicators.

Weight and handling

Balance strength against the reality of lifting, transporting and storing your truss on tour.

Buying Guide: Which Truss for Stage Height, Span and Application

The right truss depends on where and how you rig it. This buying guide helps professionals and newcomers decide with confidence.

Match series to application

• Indoor, short spans, fast set-ups: a light 290 mm square truss such as the H30V or a comparable Naxpro FD34 handles lighting bars and small grids.
• Wide spans, ground support, roofs: step up to heavy-duty 50 mm / 3 mm systems (H40V class or Naxpro HD34) for the required load reserve.
• Extreme loads and large outdoor structures: consider a 60 mm / 5 mm system such as Naxpro GS94.

Calculate span and load first

Start from the real hanging load and the free span between supports, then read the manufacturer's load table. Only when the WLL comfortably exceeds your load should you finalise the series.

Plan for compatibility

If you already own truss, verify coupler and spigot compatibility before mixing brands. Mismatched connection systems must never be forced together.

Budget realistically

Higher wall thickness and larger diameters cost more but unlock longer spans and higher safety reserves. Buying too light is the most common and most dangerous mistake.

If you are unsure, contact LTT for a straightforward recommendation – as your specialist we will steer you to the optimal solution rather than the most expensive one.

Prolyte vs. Litetruss vs. Naxpro-Truss: An Honest Comparison

Buyers deserve transparency, so here is a fair comparison rather than one-sided praise. Prolyte remains a well-known and respected brand, but it is no longer the sole market leader – and its recent history matters. Prolyte went through insolvency and is now part of the Czech group Area Four Industries.

For many projects, Litetruss offers equal or higher quality at a more attractive price. Litetruss is partly produced in Germany, including custom fabrication, which gives you short lead times and reliable statics. When you are looking for a leading, innovation-driven brand, Naxpro-Truss is one of the market's front runners and forms the backbone of LTT's own production.

Our recommendation: if you already run a Prolyte inventory, extend it with genuine Prolyte parts. If you are specifying a new system, seriously compare Litetruss and Naxpro-Truss – you often gain equal or better quality, faster availability and a stronger price.

Applications: Which Truss for Stages, Events and Installations

Prolyte and comparable truss systems are used wherever equipment needs to be suspended, supported or elevated safely.

Stages and roofs

From small covered stages to large arc roofs, truss carries lighting, PA and video while roof systems add weather protection for open-air shows and festivals.

Live events and touring

Square truss grids, goalposts and towers form the skeleton of concert productions, holding moving lights, line arrays and LED walls. Lightweight series speed up load-in and load-out.

Corporate events and exhibitions

Modular truss builds branded gateways, hanging signs and clean product presentations on trade fair stands, letting exhibitors create a genuine wow effect.

Theatres, clubs and houses of worship

Fixed truss grids provide flexible, repeatable rigging points for lighting and scenery in permanent venues.

Installations and TV production

Ground support systems and towers deliver stable structures for studios, LED walls and long-term installations, as demonstrated in research and performance spaces at institutions such as universities.

For a complete setup, combine your truss with matching decks and staging for performance surfaces, and with the right rigging hardware for safe suspension.

Accessories and Compatibility: Connectors, Hardware and Add-Ons

A truss system is only complete with the right accessories. Plan them into your budget from the start.

Connection and rigging hardware

• Conical couplers, connection pins and R-clips for joining sections.
• Half couplers, clamps and hooks to attach fixtures and rigging points.
• Base plates, outriggers and ballast for free-standing towers and ground support.

Motion and safety add-ons

• Chain hoists (such as Prolyft) for motorised lifting.
• Safety steels / secondary suspensions as backup on every hung load.
• Truss protectors, sleeves and dolly boards for transport and storage.

Compatibility between brands

Many buyers run mixed fleets. Whether Prolyte, Litetruss, Naxpro-Truss or Global Truss sections can be combined depends on identical tube diameter and, above all, a matching connection system. Conical-coupler systems from different makers are not automatically interchangeable. Before mixing brands, check the connector type, spigot geometry and the manufacturer's compatibility statement – and never force incompatible parts together, as this compromises the certified load capacity.

When in doubt, ask LTT which coupler and adapter options keep your existing inventory usable.

Safety and Standards: EN 1090, DGUV Vorschrift 17 and TÜV Certification

Truss is safety-relevant load-bearing equipment, so compliance is not optional. Understanding the key standards protects your crew, your audience and your business.

EN 1090

EN 1090 governs the manufacture and CE marking of load-bearing aluminium and steel structures. Certified production ensures documented, traceable structural quality – a core reason to buy from established manufacturers.

DGUV Vorschrift 17 (formerly BGV C1)

In the German-speaking event industry, DGUV Vorschrift 17 sets the rules for stages and production facilities, including requirements for suspended loads and safe rigging above people.

TÜV SüD and product certification

Independent certification, for example the TÜV certification of the Prolyte GM5 stage deck, confirms that a product meets defined safety and reliability criteria. Certificates give you documented proof for clients and authorities.

Statics and inspection

Always work within the published load tables, keep adequate safety factors, and have truss regularly inspected for damage. Deformed tubes, cracked welds or worn couplers must be taken out of service immediately. Correct rigging documentation and a qualified rigger are as important as the hardware itself.

Brand Background: From Leek to Area Four Industries

Understanding Prolyte's history helps you make an informed decision. Prolyte was founded in 1991 in Leek, in the Netherlands, and built its reputation on a "one-step-ahead" mentality, pioneering products such as the Verto truss and setting benchmarks in rigging and staging.

For many years Prolyte was regarded as one of the global leaders for the entertainment industry. More recently, however, the company went through insolvency and was taken over by the Czech group Area Four Industries, which today owns and continues the brand.

What does that mean for you? Prolyte remains a recognised name with a broad, capable range, and you can still source it at LTT. At the same time, the market has evolved: robust, German-produced alternatives such as Naxpro-Truss and Litetruss now match or exceed Prolyte on quality and value. That is why we present these options side by side – so your purchase rests on transparency rather than legacy reputation alone.
