Dragon Stage
A natural aluminum truss is easy to see under stage lighting.
For many concerts, weddings, theatres, clubs and corporate events, that is not always desirable.
A black truss allows the supporting structure to visually recede into:
black drape + lighting fixtures + stage backgrounds + LED systems
so the audience sees more of the event design and less of the supporting framework.
This Black 300mm Plate-Ended Bolt Box Truss combines that darker visual finish with a professional four-chord bolt-truss construction.
The truss uses approximately:
300 × 300mm / 12 × 12in square section
with:
50mm main tubes
and:
3mm main tube wall thickness
for professional event and rental applications.
Unlike conical spigot truss, each section terminates in a rigid plate-ended bolt connection, allowing compatible sections to be connected using bolts, nuts and washers.
DragonEvent will offer standard lengths from:
0.5m to 2.5m
with custom lengths available when the buyer needs to match a venue, exhibition layout or existing truss inventory.
For other straight truss options, browse Straight Truss.
The most important difference from the natural aluminum version is visual.
Black truss is particularly useful when the structure should blend into the background rather than become a visible part of the event design.
Typical environments include:
theatres;
concerts;
DJ events;
clubs;
wedding stages;
black-box venues;
corporate events;
LED screen structures;
dark exhibition booths.
Under controlled lighting, black truss generally attracts less visual attention than natural silver aluminum.
Nominal truss section:
Approx. 300 × 300mm
or:
Approx. 12 × 12in
The four-chord square geometry makes this product suitable for professional temporary event structures rather than lightweight decorative DJ applications.
Main chord specification:
Tube Diameter: Approx. 50mm / 2in
Wall Thickness: 3mm / approx. 0.12in
Diagonal tube specification:
Approx. 25mm / 1in
with:
3mm wall thickness
for this product configuration.
This is one reason the product should remain clearly separated from lighter 290mm or 300mm truss using thinner tube walls.
Each section uses a rigid end plate.
Adjacent sections are positioned:
plate to plate
and secured using compatible bolt hardware.
This connection method is particularly relevant for rental companies that already own plate-ended bolt truss and need:
replacement sections;
additional lengths;
black extensions;
custom-sized sections.
Approximate connection geometry:
Bolt Center Pattern: 171.5 × 171.5mm
approximately:
6.75 × 6.75in
Bolt hole diameter:
Approx. 5/8in
When adding this product to an existing system, these dimensions are more important than the general description “300mm truss.”
Standard product variants can be offered between:
0.5m and 2.5m
For example:
0.5m
1.0m
1.5m
2.0m
2.5m
You can set the exact SKU structure and pricing directly in the product backend.
Custom lengths are useful when standard modules do not create the exact finished dimension.
Typical situations include:
fixed theatre dimensions;
wedding installations;
exhibition booths;
LED structures;
replacement of an existing special-length section;
permanent rental packages for a recurring venue.
For general rental inventory, standard modular lengths remain more flexible.

Before connecting this truss to an existing bolt-truss system, confirm:
overall truss section + end-plate dimensions + bolt-center distance + bolt-hole diameter + tube position
Do not assume compatibility based only on the nominal 300mm size.
Black is especially useful around stage lighting because it reduces the visual contrast between the support structure and:
black lighting fixtures;
black cables;
black drapes;
dark stage backgrounds.
This allows the lighting equipment and performance to remain the visual focus.
In theatre environments, visible silver aluminum may reflect stage light and draw attention.
Black truss is a more natural visual choice for:
theatres;
studios;
performance spaces;
black-box venues;
rehearsal spaces.
Modern wedding production often combines:
black truss + lighting + LED screens + fabric + floral decoration
where the structural equipment is not intended to dominate the design.
For these events, the black finish can be more discreet than natural aluminum.
For DJs and clubs, black truss works naturally with:
moving heads;
beam lights;
PAR fixtures;
LED bars;
black DJ booths;
dark room environments.
This is a more application-specific reason to choose the black version rather than simply selecting it because of color preference.
The black 300mm box format can form part of suitable:
lighting frames;
concert truss structures;
side structures;
ground-support arrangements;
temporary production systems.
For larger towers, long spans or significant suspended loads, the complete system should be technically evaluated rather than selecting the straight section alone.
Black truss can also be used where the exhibition design uses:
dark branding;
LED displays;
black wall systems;
premium technology displays;
theatrical booth lighting.
Custom lengths may help fit fixed booth dimensions more accurately.
Choose black when your priority is:
visual concealment + dark event environment + lighting integration
Choose natural aluminum when:
traditional truss appearance + maximum visual visibility of the structure
is acceptable or preferred.
This is the main difference between the two versions.
This product uses:
Plate-Ended Bolt Connection
not:
Spigot / Conical Connection
Check your existing system before ordering.
If you already own bolt truss, confirm:
bolt center distance
hole diameter
overall plate geometry
before purchasing additional sections.
For a required:
5m beam
possible combinations may include:
2.5m + 2.5m
or:
2m + 2m + 1m
The right choice depends on:
transport + storage + future reuse + connection count.
Custom length makes particular sense for:
theatres;
exhibition booths;
fixed wedding structures;
permanent club installations;
recurring rental layouts.
If the truss will constantly be reconfigured, standard modular lengths usually provide better long-term flexibility.
The structural format can be similar, but the buying purpose is different.
The truss should visually disappear.
Best suited to:
theatres;
DJ setups;
clubs;
concerts;
weddings;
LED structures;
dark exhibition designs.
The truss itself can remain visible.
Natural silver is often appropriate for:
general event production;
industrial-style exhibitions;
conventional rental inventory;
structures where appearance is secondary.
This distinction allows buyers to choose by event environment, not simply by color.
For one additional black straight section in an existing compatible system:
1 × Black Bolt Truss Section
plus the matching:
**Bolts
Nuts
Flat Washers
Lock Washers**
may be sufficient.
For lighting applications, also consider:
**+ Black or compatible 48–51mm Fixture Clamps
Required Fixture Safety Hardware**
For related mounting and connection parts, browse Truss & Rigging Accessories.
The main reason to choose black is usually the event environment.
If the truss is heavily visible under lighting, black can materially change the visual result of the setup.
A black beam connected to silver corners or towers may create a visibly mixed structure.
If appearance matters, plan:
Straight Truss + Corners + Bases + Clamps
as one finish system.
“300mm” does not define the connection.
Measure the plate and bolt pattern.
This product uses:
50mm main tubes + 3mm wall
and should not be confused with lightweight black truss using thinner tubing.
Longer truss means fewer connections, but it also means:
larger transport size + larger storage requirement + less modular flexibility.
Rental companies often benefit from a mixture of lengths.
Custom length is valuable when it solves a recurring problem.
Too many unusual sections can make rental inventory harder to organize.
Start with standard lengths and add custom sections when the application genuinely requires them.
The black version should not be assigned a different structural rating simply because of its finish.
Actual capacity depends on:
truss geometry + material + tubes + span + connection + support condition + load arrangement.
For other truss sizes, lengths and configurations:
For clamps, bolts and mounting hardware:
For buyers comparing different professional truss systems:
The main difference is the finish and intended visual application.
The black version is especially suited to theatres, concerts, clubs, weddings and dark stage environments where the supporting structure should attract less visual attention.
Approximately:
300 × 300mm / 12 × 12in
Approximately:
50mm / 2in outside diameter
with:
3mm wall thickness.
No.
This is positioned as a professional 300mm heavy-duty plate-ended bolt box truss.
Standard variants can be offered from:
0.5m to 2.5m
with additional custom lengths available.
Yes.
Provide the required finished length and quantity for production confirmation.
Yes.
The darker finish is particularly useful where the truss should blend into black stage backgrounds and lighting environments.
Yes.
Black truss is often a practical choice where lighting, LED displays and decoration should remain visually dominant over the supporting frame.
No.
It uses a plate-ended four-bolt connection.
Possibly, but compatibility must be confirmed.
Check:
end-plate dimensions + bolt centers + hole diameter + tube position.
They can be supplied according to the selected package.
Confirm whether you need:
truss only
or:
truss + connection hardware.
There is no single load value suitable for every length and configuration.
Allowable loading depends on the complete truss system, span, support arrangement and load position.
