What is a round aluminium tube 48.3 x 3 mm? Fundamentals and function

The round aluminium tube 48.3 x 3 mm is a straight, hollow extruded aluminium profile with a 48.3 mm outer diameter and a 3 mm wall thickness. It is manufactured by Riggatec from the alloy EN AW 6082 T6, a high-strength structural aluminium that is corrosion-resistant, non-magnetic and easy to machine. The internal bore measures roughly 42.3 mm, which is why the 48.3 mm dimension corresponds to the common DN50 pipe reference used across the trade.

How it differs from a certified truss chord

It is important to understand that this round tube is an accessory and construction part, not a certified truss chord. A Naxpro-Truss ladder or box truss is a load-rated system with defined working load limits, tested chords and diagonals. The 48.3 x 3 mm round tube, by contrast, is used for non-load-bearing tasks: as a stabiliser, a lighting or banner carrier, or a cantilever for add-ons. It is not a substitute for a rated truss when suspending people or heavy point loads.

Why aluminium instead of steel

Compared with a steel tube of the same dimensions, this aluminium version is far lighter yet still robust, and it resists corrosion without any coating. That makes it ideal for temporary stage and exhibition rigs that are assembled, transported and dismantled repeatedly. For DIY and prototyping it can be sawn, drilled and screwed with standard workshop tools.

Material properties of the Riggatec aluminium tube

The Riggatec round aluminium tube 48.3 x 3 mm owes its performance to the alloy EN AW 6082 T6, a hardened structural aluminium prized in event technology for its strength-to-weight ratio.

• Corrosion-resistant and weatherproof – suitable for long-term outdoor use without significant surface degradation.
• Lightweight yet robust – at approximately 1.15–1.16 kg per metre, the tube is far lighter than steel while remaining dimensionally stable.
• Non-magnetic – an advantage for sensitive applications and clean signal environments.
• Excellent machinability – it can be cut, drilled, tapped and welded with standard tools.
• Fine surface quality – available raw/blank or, in comparable Riggatec ranges, powder-coated in RAL9005 black for a discreet stage look.

The alloy and manufacturing comply with recognised standards, including EN 573-3 (chemical composition), EN 755-2 (mechanical properties), EN 755-1 (technical delivery conditions) and EN 755-9 (profiles, dimensional and form tolerances). Length tolerance is held to +/- 1 %, which keeps your builds accurate. Because aluminium is prone to surface scratches, handle the tube carefully during assembly to preserve its appearance.

Applications: where the 48.3 x 3 mm round tube is used

The round aluminium tube 48.3 x 3 mm is a versatile building block across event technology, stage and exhibition builds. Its combination of a manageable diameter and a sturdy 3 mm wall makes it a favourite for a wide range of mounting tasks.

Typical use cases

• Lighting support / hanging lighting – as a light bar to hang fixtures, PARs or effect units below or beside a truss.
• Banner and tarpaulin carrier – as a horizontal or vertical member to tension advertising banners, backdrops and stage tarpaulins.
• Stabiliser and cantilever – to brace, extend or offset elements within a truss construction.
• Decoration mounting – as a discreet carrier for stage decoration, signage and set dressing.
• Indoor and outdoor use – equally at home in clubs, theatres, churches and on open-air stages thanks to its weatherproof aluminium.

Event technicians, exhibition builders, DJs, bands and lighting designers all reach for this tube when they need a clean, lightweight carrier that stays out of the audience's eye. To integrate the tube into a rated support structure, browse the matching Naxpro-Truss systems and rigging accessories in the LTT truss range.

Use as a stabiliser and cantilever in truss constructions

One of the most valuable roles of the 48.3 x 3 mm round tube is as a supplementary element within truss constructions – something most generic aluminium suppliers never explain.

Integration with Naxpro-Truss and other systems

Inside FD-, HD- or GS-series truss builds, the round tube serves as a stabiliser that ties elements together, a cantilever that extends a mounting point beyond the main structure, or a carrier for banners and decoration hung off the rig. It is fixed with couplers, clamps or purpose-made connectors rather than being spigoted like a truss chord.

Load-bearing limits and safety guidance

Be clear about the structural role: the 48.3 x 3 mm round tube is a non-load-bearing accessory part, not a rated truss chord. It carries no published working load limit (WLL) for suspending people or heavy point loads. For any suspension above people, professional event rigging must follow DGUV Vorschrift 17 (formerly BGV C1) and use certified, load-rated truss and rigging hardware. Use this round tube only for the light-duty carrying, bracing and decoration tasks it is designed for, and let a qualified rigger sign off on your overall construction. That distinction protects both your crew and your audience.

Technical buying criteria: specifications, dimensions and material

When you specify the round aluminium tube 48.3 x 3 mm, these are the concrete technical values that matter.

What to check before ordering

Confirm the length you need and whether a cut-to-size service applies, verify that the 48.3 mm diameter matches your clamps, couplers and connectors, and decide between a raw/blank finish for workshop builds and a powder-coated black look for visible stage positions. The 3 mm wall gives markedly more rigidity than a thinner 1.2–2 mm tube, which is worth paying for when the tube spans longer distances or carries banners in wind.

Comparison: 48.3 x 3 mm round tube versus Naxpro-Truss tube diameters

Buyers often ask how the 48.3 x 3 mm round tube relates to the tube dimensions used in Naxpro-Truss systems. The key point: the round tube is a construction accessory, whereas the truss tubes below form part of rated, load-bearing truss chords and diagonals.

For reference, Naxpro FD21-24 uses a 35 mm tube with 2 mm wall, GS94 uses a 60 mm tube with 5 mm wall, and diagonals run 40 x 3 mm. Choose the 48.3 x 3 mm round tube when you need a lightweight carrier or brace; choose a rated Naxpro truss when the element must bear load.

Buying guide: choosing tube, wall thickness and length

This buying guide helps you pick the right 48.3 x 3 mm round tube for your stage or exhibition build – niche-specific advice you rarely find elsewhere.

Pro versus entry-level selection

• Light-duty decoration or signage: a shorter, raw/blank tube keeps cost and weight down.
• Banner and tarpaulin carriers: favour the full 3 mm wall for stiffness, especially for spans exposed to wind outdoors.
• Visible stage positions: choose a powder-coated black finish so the tube disappears into the rig for a clean look on camera.
• Repeated touring use: the robust 3 mm wall resists dings and stays straight through many load-in cycles.

Getting the length right

The Riggatec round tube is available in several lengths and can be cut to size – typically from a 5 cm minimum up to 220 cm, with longer cuts on request. Measure your clear span and add allowance for clamp positions before ordering, and remember that saw-cut lengths carry a small tolerance. If you are unsure which combination of tube, end caps and connectors fits your lighting, banner or decoration task, contact the LTT team as your reliable partner for a tailored recommendation.

Care, maintenance and safety of the aluminium round tube

The 48.3 x 3 mm aluminium round tube needs little upkeep, but a few care and safety habits keep it in service for years.

Care and cleaning

• Wipe the raw/blank surface with a soft cloth; use mild soapy water for stubborn dirt and dry thoroughly.
• Avoid abrasive pads on powder-coated black tubes to protect the UV-resistant RAL9005 finish.
• Handle carefully during assembly, as aluminium is prone to surface scratches.
• Store tubes flat and supported so they stay straight between events.

Safety notes

Remember that this round tube is a non-load-bearing accessory, not a certified truss chord. Never use it to suspend people or heavy loads above an audience; use rated, tested truss and rigging hardware and follow DGUV Vorschrift 17 for professional rigging. Deburr freshly cut edges and fit end caps to prevent cuts. If a tube shows a bend, crack or heavy impact damage, retire it from structural service.
