The FD 33 Circular Truss series by Naxpro Truss is a heavy-duty version of their Triangular Truss (3-Point) in a curved format. This series belongs to the FD 3X line, characterized by a larger cross-section than the popular FD 2X series, which gives it a significantly higher load capacity and greater torsional rigidity.

The FD 33 is the standard medium-to-heavy load triangular solution for large stages and exhibition booths, offering the best weight-to-load performance within the triangular range.

⚙️ Features and Structural Improvement

Feature FD 33 Detail Comparison with FD 23
Structure 3 Point Circular (Triangular Truss), classified as Fair Duty (FD). Maintains the triangular geometry.
Section Dimensions Larger triangular section (approx. 29 cm side length). Larger (FD 23 is approx. 22 cm). Dramatically increases bending resistance.
Main Tubes Three parallel tubes of 50 mm diameter with a wall thickness of 2 mm. The main tube diameter is the same.
Load Capacity Medium to Heavy. The combination of triangular geometry (excellent torsional stability) and the larger cross-section results in a much higher load capacity for heavy lights and AV equipment. Significantly Higher. It is suitable for loads that the FD 23 could not safely handle.
Curve Types Available in A/A (Up/Down), INT (Interior), and EXT (Exterior) (circles from 2m to 10m Outer Diameter). Same as the FD 23.
Ideal Application The workhorse for large-scale suspended structures where structural reliability and the installation of professional lighting and sound are required. Main structure for large grids and exhibition stands.
Connection Standard conical connection system, compatible with the FD 33 series. Maintains compatibility with the rest of the FD 3X series.
