Aluminum Alloy Closed Cable Tray
The tray body is manufactured using pure aluminum alloy integrated forming technology, made of high-strength aluminum alloy through die drawing or bending and welding, with strong structural integrity and no weak weld seams.
- Significantly reduces the load on supports and building structures, especially suitable for long-span or high-rise vertical laying.
- Easy installation: cutting, connecting, and opening holes are less labor-intensive than steel, effectively shortening construction time.
- Long service life with almost no maintenance required in normal indoor environments.
- Non-magnetic material causes no interference to weak current signals, suitable for data transmission lines.
Performance Features
Lightweight (density approximately 1/3 of steel), with excellent inherent oxidation resistance and not prone to rust. Aluminum alloy has good thermal conductivity and heat dissipation, effectively helping cables dissipate heat and extending cable service life. The surface can be further treated with anodizing or powder coating to enhance corrosion resistance.
Applicable Scenarios
Electrical shafts in high-rise buildings, data center equipment rooms, communication base stations, lightweight installation scenarios, and old building renovation projects with load limitations.
Stainless Steel Closed Cable Tray
Made of 201, 304, or 316 stainless steel primary sheets, formed through precision bending, welding, and polishing. Among them, 304 is the general corrosion-resistant grade, while 316 contains molybdenum for better pitting resistance and seawater resistance.
- Long-term use in harsh environments without deformation or damage, service life over 30 years.
- No additional coating required, no risk of coating peeling, hygienic and easy to clean.
- High mechanical strength, outstanding impact and vibration resistance.
- 304/316 materials meet high standards for food, pharmaceutical, and marine engineering applications.
Performance Features
Extremely strong resistance to acids, alkalis, salt spray, and chemical corrosion, waterproof and rust-proof, truly "never rust" under normal service conditions. Stainless steel has good high-temperature resistance, maintaining dimensional stability and mechanical strength over a wide temperature range.
Applicable Scenarios
Chemical production workshops, wastewater treatment plants, coastal areas with high salt spray corrosion, offshore platforms, electroplating plants, pharmaceutical factories, food processing workshops, and other highly corrosive or high-hygiene environments.
Supporting Accessories System
To meet complex on-site wiring routing requirements, the closed cable tray can be equipped with a full range of standardized accessories:
Horizontal Elbow – Allows 90° or 45° turning in the same plane.
Vertical Elbow – Allows upward or downward turning in the vertical direction.
Tee – Used to branch off a sub-line from the main line, T-shaped connection.
Cross – Cross-shaped branch connection for four directions.
End Cap – Seals the end of the cable tray to protect cable ends.
Connecting Bolts – Stainless steel or hot-dip galvanized bolts, ensuring joint fastening and electrical continuity.
Cantilever Brackets / Supports – Cantilever brackets for wall or column mounting, with adjustable height and spacing.
- All accessories are consistent with the tray body material and surface treatment, ensuring uniform overall anti-corrosion performance. The accessory system can flexibly adapt to various wiring topologies such as straight sections, horizontal bends, vertical bends, and branches, meeting all installation and layout needs from simple corridors to complex workshops.
- The closed cable tray, with the core advantages of lightweight and high efficiency of aluminum alloy and the rugged corrosion resistance of stainless steel, together with a complete accessory system, provides safe, reliable, and long-life cable protection solutions for modern industrial and civil buildings.
