How to measure
Provide outside radius or diameter, total included angle, arc rise and chord width, truss profile, support or suspension method, end positions, loads, finished height and adjacent straight sections.
Curved stage & scenic geometry · circular truss guide
Semicircle & Arc Truss Malaysia.
Factory-made curved truss segments assembled as a half-circle, partial arc or curved scenic line for stages, entrances and displays.
What the structure achieves
Define the complete circular outcome.
An arc uses selected factory-made curved segments rather than a complete 360-degree ring. It must be described by profile, outside radius or diameter reference, included angle, orientation and end conditions.
The closest system guide is Circular & Curved Truss. The relationship helps establish the correct setup route; it does not make different circle profiles, segment systems or connectors interchangeable.

Circular design
Geometry, equipment and audience belong on one drawing.
Coordinate the true arc with the visible scenic curve. A drawing should distinguish chord width, arc length and rise so artwork, panels and attachment points are not based on the wrong measurement.
Manufactured geometry
Profile, diameter, segments, angles, cutting and connection system are identified.
Complete load path
Venue points, hoists, towers, bases, legs or ground support are mapped.
Installed positions
Lighting, LED, scenic, signs, décor, cables and hardware use verified data.
Clearance and access
Audience, stage, camera, service and installation zones remain usable.
Suitable applications
Where semicircle & arc truss fits.
Curved entrances
Diameter, support method, loads and event clearances are matched to the actual project.
Stage headers
Diameter, support method, loads and event clearances are matched to the actual project.
Scenic arches
Diameter, support method, loads and event clearances are matched to the actual project.
Exhibition features
Diameter, support method, loads and event clearances are matched to the actual project.
Wedding backdrops
Diameter, support method, loads and event clearances are matched to the actual project.
Lighting arcs
Diameter, support method, loads and event clearances are matched to the actual project.
When to choose another geometry
Do not bend straight truss, combine unrelated curved segments or approximate an arc by forcing connections out of alignment.

Circular load boundary
A circle is not a straight span bent into shape.
Use the real manufactured radius, included angle, rise, chord and end conditions in stage, print and scenic drawings. Do not force straight or unrelated curved segments to match an artwork curve.
Identify and orient every segment before assembly, use compatible connections, support the arc during installation and inspect the completed curve and end interfaces.
Manufacturer circular-truss data can depend on diameter, profile, orientation, suspension count and load distribution. Final suitability must be checked for the exact system and arrangement.

Delivery, assembly, loading, inspection, handover and dismantling can be coordinated.
Circular structure questions
Semicircle & Arc Truss FAQ.
What sizes are available for semicircle & arc truss?
Common enquiry references include 2 m half-circle, 3–5 m stage arc, 6–10 m entrance curve, Custom arc by degrees. Exact diameter, radius, included angle, profile, segment count, connection and availability are confirmed for the project.
How much does semicircle & arc truss cost?
Use RM 1,500–RM 8,000+ as an early Malaysia setup range. The quote depends on circle or arc geometry, support or suspension, equipment, decoration, hoists, venue, crew, access, transport and duration.
How should the circular truss be measured?
Provide outside radius or diameter, total included angle, arc rise and chord width, truss profile, support or suspension method, end positions, loads, finished height and adjacent straight sections.
Can lighting, LED, flowers or signs be attached?
Only declared items included in the complete load and attachment review should be added. Provide exact models or fabrication data, installed weights, positions and proposed hardware.
Can this circular structure be used outdoors?
Outdoor use requires review of ground, bases or towers, ballast or foundations, exposed equipment and surfaces, weather conditions, monitoring and the operating response.
Does the webpage confirm CK stock or structural capacity?
No. Website sizes explain enquiry formats. The written quotation confirms the actual compatible system and availability; final suitability follows the exact project data and required technical review.
