How to measure
Provide clear stage or screen opening, curve radius or outside dimensions, total height and width, stage level, profile, supported equipment, scenic cladding, base depth, rear access and indoor or outdoor conditions.
Curved stage & scenic geometry · circular truss guide
Curved Stage Portal Truss Malaysia.
Curved or arched truss framing around a stage, screen or scenic focal point for concerts, launches, awards and wedding productions.
What the structure achieves
Define the complete circular outcome.
A curved stage portal shapes the main event elevation while providing declared lighting, scenic or branding positions. The opening, curve, supports and rear production access must be designed as one complete portal.
The closest system guide is Stage Truss Structure. 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.
Use the curve to focus attention toward the performer, screen or central scenic element. Align LED edges, artwork and lighting positions with the real manufactured arc rather than an approximate graphic curve.
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 curved stage portal truss fits.
Concert stages
Diameter, support method, loads and event clearances are matched to the actual project.
Product launches
Diameter, support method, loads and event clearances are matched to the actual project.
Awards shows
Diameter, support method, loads and event clearances are matched to the actual project.
Wedding stages
Diameter, support method, loads and event clearances are matched to the actual project.
Cultural performances
Diameter, support method, loads and event clearances are matched to the actual project.
Scenic LED surrounds
Diameter, support method, loads and event clearances are matched to the actual project.
When to choose another geometry
A straight goalpost is more practical when curved geometry adds no useful sightline, design or production benefit.

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.
Coordinate stage, truss, LED, scenic and lighting installation. Erect and inspect the portal before applied finishes block connections or rear access.
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.

Circular structure questions
Curved Stage Portal Truss FAQ.
What sizes are available for curved stage portal truss?
Common enquiry references include 12 ft curved portal, 20 ft stage arch, 30 ft scenic curve, 40 ft+ custom stage portal. Exact diameter, radius, included angle, profile, segment count, connection and availability are confirmed for the project.
How much does curved stage portal truss cost?
Use RM 2,500–RM 15,000+ 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 clear stage or screen opening, curve radius or outside dimensions, total height and width, stage level, profile, supported equipment, scenic cladding, base depth, rear access and indoor or outdoor conditions.
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.
