Cable tray cover plate buckle specifications

Cable tray cover plates with turn buckles typically feature galvanized steel or aluminum construction, with turn buckle spacing ranging from 500 mm to 1000 mm depending on the model and load requirements.

Material and Construction

Cable tray covers are generally made from strip galvanized steel with a thickness of 2 mm, often reinforced with aluminum chequer plates of 2–4 mm for walkable, non-slip surfaces. Covers can be flat, flanged, or hat-shaped, and may be ventilated or solid depending on the application. Materials are selected for corrosion resistance, including options like aluminum, mill-galvanized steel, galvannealed steel, and stainless steel (304 or 316) for outdoor or harsh environments.

Turn Buckle Fastening

Turn buckles are used to secure the cover to the cable tray. Typical spacing between turn buckles ranges from 500 mm to 1000 mm, with closer spacing recommended for walkable covers or areas exposed to wind or pressure impacts. For outdoor installations, additional securing measures such as cover clamps may be required, as turn buckles alone may not resist wind loads.

Installation Considerations

Indoor use: Standard turn buckle spacing is usually sufficient; clips or clamps may be used depending on the cover type. Outdoor use: Covers must account for wind, draught, or pressure impacts. Extra securing elements or closer buckle spacing may be necessary.

Walkable covers: Reinforced with chequer plates and riveted aluminum for non-slip surfaces; turn buckle spacing is often 500 mm for added stability.

Summary

When selecting a cable tray cover with turn buckles, consider: Material thickness: 2 mm steel with optional 2–4 mm aluminum chequer plateTurn buckle spacing: 500 mm for high-load or walkable covers, 1000 mm for standard coversEnvironmental factors: Outdoor use requires additional securing against windCover type: Flat, flanged, hat-shaped, ventilated, or solid depending on application. These specifications ensure proper protection of cables, safe walkable surfaces, and secure fastening under varying environmental conditions.
