HD 43 Circles

Naxpro HD 43 Circular Truss (3-Point / Triangular) with 50x3mm tubes and 39 cm. Maximum versatility and rigidity for large complex structures and critical loads.

The HD 43 Circular Truss series by Naxpro Truss is the large-size Triangular Truss (3-Point) curved structure within the Heavy Duty (HD) range. This series merges the extra-large triangular cross-section (39 cm) with the maximum robustness of the 50x3 mm main tube.

The HD 43 is engineered to provide ** maximum versatility and rigidity** in large-scale and complex structures. It is the strongest 3-point option for large circular structures with critical loads.

⚙️ Features and Structural Improvement

Feature HD 43 Detail Comparison with FD 43 / HD 33
Structure 3 Point Circular (Triangular Truss), classified as Heavy Duty (HD). Maintains the triangular geometry.
Section Dimensions Extra-large triangular section (approx. 39 cm side length). Upgrade from HD 33 (29 cm): Higher inertia for larger structures and longer spans.
Main Tubes Three parallel tubes of 50 mm diameter with a wall thickness of 3 mm. Upgrade from FD 43 (2 mm): Higher load capacity, bending resistance, and rigidity.
Load Capacity Maximum Versatility Heavy Duty. The combination of large section (39 cm) and thick tube (3 mm) provides unrivaled resistance for handling critical loads with excellent directional stability. Extreme Capacity. The most powerful and rigid option for large complex structures in the triangular format.
Curve Types Available in A/A (Up/Down), INT (Interior), and EXT (Exterior) versions (circles from 2m to 10m Outer Diameter). Same as the 3X series.
Ideal Application Large circular structures, complex roof rings, and setups that require maximum rigidity and strength to support high loads, but benefit from the unique orientation of the triangular truss. Leading solution for large productions and events.
Connection Standard conical connection system, compatible with the HD 4X series. Maintains compatibility within the HD 4X range.
