Decorative circular features
Wedding florals, fabric, chandeliers and scenic rings need their own installed-weight and attachment details.
Open suspended décor-ring guide →Circular and curved truss specialists
Truss circles, arcs, halos and 360° event structures.
Plan circular lighting rings, ground-supported and flown circles, concentric rigs, stage arches, DJ halos, round booths, curved LED support, dance-floor features, circular roofs, ovals and scenic waves.
Profile versus structure
A curved segment is not yet a finished circular system.
Factory-made curved truss segments form a specified ring, arc or custom line. The finished event structure also needs compatible connections, orientation, supports or suspension, applied loads, access and an installation method.
CK confirms the actual system and availability during quotation. The diameter or example shown on a webpage is not a universal stock or load promise.
Circular truss measurement
Six geometry facts every drawing should label.
01Outside diameter or radius reference
02Required clear inside diameter
03Truss profile and orientation
04Number of segments and included angles
05Support or suspension positions
06Trim height and total footprint

Useful early setup bands.
| Circle size | Typical event scale | Important note | Setup range |
|---|---|---|---|
| 2–3 m outside diameter | Compact decorative, photo, DJ and selected lighting rings | Confirm profile depth, inside clear opening and support method | RM 1,200–RM 8,000+ |
| 4–5 m outside diameter | Wedding, stage, ballroom, exhibition and dance-floor features | Common setup scale; exact segments and loading remain system-specific | RM 2,000–RM 12,000+ |
| 6–8 m outside diameter | Production lighting, brand activation and large exhibition circles | Usually requires more substantial support, lifting, access and logistics | RM 4,000–RM 20,000+ |
| 10 m+ outside diameter | Major production rings, roofs and large 360-degree structures | Project assessment, exact manufacturer data and venue or ground information | Project quotation |
Outside diameter is a common ordering reference, but the exact manufacturer convention must be confirmed. Circumference equals π × diameter for general layout setup; it is not a substitute for the manufacturer’s segment geometry, cutting, connection or load information.

Open circular and curved truss profile →Manufacturer context
Circles are calculated differently from straight truss.
Eurotruss notes that diameter affects the number of curved segments and recommends checking the circle or curved structure’s load-bearing capacity separately. Prolyte publishes product-specific circular-truss data whose conditions depend on diameter and suspension-point arrangement.
CK therefore asks for the exact circle, profile, support or suspension and load positions instead of publishing one universal capacity.

Circular truss FAQ
Diameter, support and use questions.
What circular truss sizes are available?
Common enquiry diameters begin around 2 m and extend through 3 m, 4 m, 5 m, 6 m and larger project-specific circles. The actual profile, segment count, connections and availability must be confirmed.
Is circle truss measured by inside or outside diameter?
Manufacturer product descriptions commonly use an outside diameter, but the clear inside opening is smaller by the truss profile depth on both sides. Every quote and drawing should label the measurement convention.
Can circular truss be ground-supported or flown?
Yes, when the exact system is configured for the chosen method. Ground support transfers loads through towers or legs and bases; flown circles require approved venue points, hoists, hardware and a rigging plan.
Can a truss circle support lights, LED, flowers or chandeliers?
Only declared equipment and decoration included in the complete checked load arrangement should be attached. Provide models, verified weights, positions and attachment methods.
Can CK provide circular and curved truss structures?
CK can plan and quote circular and curved event structures subject to the required diameter, compatible system, current availability, venue or site and complete project assessment.
Is a circular roof the same as a covered lighting ring?
No. A circular roof is a complete temporary roof system with radial members, supports, membrane, drainage, environmental loads and operating limits. A lighting circle should not be covered with an improvised sheet.
