Starduct cable tray & ladder — range introduction
From the punching, roll-forming and bending line at the Dan Phuong factory to the products: perforated and solid trays, cable ladder and raceway; rib stiffening, coupler-free joints, 37 VIBM test reports and the online selection tools. The 30–40 % and 15–20 s / 90 s figures are Starduct internal data. English subtitles over the Vietnamese narration until the English voice-over is recorded.

JOINTS & INSTALLATION
Coupler-free joints — fewer loose parts, faster fitting
Integral male–female ends Two lengths nest into each other and are tightened with square-neck bolts — no loose coupler. 
Clinched rungs Rungs are clinched to the side rails without welding — no weld seams to rust. 
Copper earthing washers Fitted under the joint bolts to keep electrical continuity between lengths — no separate bonding jumper. Starduct cable tray & ladderSlide 8 / 16
FITTINGS & SUPPORTS
Fittings and supports with the same joint system
Tees, bends, crosses Same integral tabs as the straight lengths; horizontal and vertical bends and matching covers. 
Threaded-rod hangers Threaded rods and UNISTAR channel hang trays from the slab; dividers separate power and control cables. 
Cantilever brackets Carry ladders and trays from walls or columns; support spacing from the load tables in the catalogue. Radii, dimensions and order codes of every fitting, cover and divider are in the catalogue of each model.
