HD 33 Circles

Naxpro HD 33 Circular Truss (3-Point / Triangular) with 50x3mm tubes and 29 cm. Versatile Heavy Duty for complex structures, high loads, and excellent deflection resistance over long spans.

The HD 33 Circular Truss series by Naxpro Truss is the curved Triangular Truss (3-Point) solution within the Heavy Duty (HD) range. It shares the compact cross-section (29 cm) of the 3X series but utilizes main tubes with 50x3 mm specifications, which maximizes its load capacity and torsional rigidity, especially valuable over long spans or in complex structures.

The HD 33 is the most versatile option in the HD 3X range, combining a compact footprint with true heavy-duty strength.

⚙️ Features and Structural Improvement

Feature HD 33 Detail Comparison with FD 33
Structure 3 Point Circular (Triangular Truss), classified as Heavy Duty (HD). Maintains the compact triangular geometry.
Section Dimensions Standard triangular section (approx. 29 cm side length). Maintains the same dimension.
Main Tubes Three parallel tubes of 50 mm diameter with a wall thickness of 3 mm. Key Upgrade: Wall thickness increased from 2 mm to 3 mm. This drastically increases load capacity and rigidity.
Load Capacity Heavy Duty. The increased material thickness provides a much higher load capacity than its FD counterpart, making it ideal for industrial rigging applications and large productions. Substantially Higher. Excellent for handling concentrated loads and reducing deflection over long spans.
Curve Types Available in A/A (Up/Down), INT (Interior), and EXT (Exterior) versions (circles from 2m to 10m Outer Diameter). Same as the FD 33.
Ideal Application Versatile solution for complex structures and large lighting/audio rigs that require high strength, but where vertical/visual space is a consideration (more discreet than the HD 34/44). Ideal for exhibition stands, roof structures, and high-weight scenic rings.
Connection Standard conical connection system, compatible with the HD 3X series. Maintains compatibility within the HD 3X range.
