Two cold-formed longitudinal rails are joined by repeated transverse rungs, creating an open carrier for large-section power cables and extended routes. The open underside distinguishes a Gi Ladder Type Cable Tray from a closed trough or perforated pan, allowing heat to escape and giving workers direct access during pulling, fastening, inspection, or adjustment. Cold-rolled steel provides tensile, bending, and impact strength. Hot-dip zinc treatment follows shaping so completed rails and rungs receive surface protection. Joint plates, brackets, grounding wire, bends, vertical fittings, reducers, branch pieces, and an optional lid continue the ladder construction through route changes.

Product Advantages
The Gi Ladder Type Cable Tray rung frame keeps the underside open, which improves ventilation and eases access around large cable groups.
Formed steel rails support cable weight and outside forces, while calculated spans can reduce intermediate support points.
Zinc classes of at least 65 μm or 85 μm protect the formed steel according to the expected exposure.
An optional lid protects the route from above, while matched fittings maintain continuity through rises, turns, reductions, and branches.
Components
Two longitudinal rails and repeated rungs form the ladder body. Joint plates connect neighboring lengths, while brackets carry the route and a grounding wire maintains continuity. Horizontal and vertical bends, reducers, branches, and junction pieces handle changes in direction or width. An optional lid adds upper shielding while the underside remains open for ventilation, pulling, inspection, and cable access.
FAQ
Q: Which cables suit the ladder configuration?
A: The open rung frame is intended for large-section cables and long-distance cable routes.
Q: How are a rise and a branch formed?
A: Matched vertical pieces, bends, reducers, and branch fittings continue the ladder frame through the route change.
Q: Which zinc thickness should be selected for a Gi Ladder Type Cable Tray?
A: Use at least 65 μm for the regular class or at least 85 μm where comparatively stronger corrosion protection is required.
