Cable Trays

Trough type cable trays are trough-shaped components made from a single sheet of steel, with a structure similar to a channel. They are used to support, protect, and organize the laying of cables, lines, and pipes. They offer strong protection, and their fully enclosed structure effectively isolates them from external environmental interference such as dust, water vapor, oil, and mechanical impact.

FRP cable trays (fiberglass cable trays) are a new type of cable support device made primarily of glass fiber reinforced plastic, combined with flame retardants, stainless steel shielding mesh, and other materials. They are manufactured using a molding process, with core materials including glass fiber (reinforcing material), resin (matrix material), and auxiliary materials. The glass fiber used is either medium-alkali fiber or, more importantly, alkali-free fiber with superior performance.

Lightweight and High-Strength: Aluminum alloy has only 1/3 the density of steel. Aluminum alloy cable trays are 60% lighter than steel cable trays while maintaining high strength, reducing the load on building structures.

Excellent Corrosion Resistance: Through anodizing, a dense oxide film is formed on the surface, increasing resistance to salt spray corrosion by more than 3 times. Suitable for highly corrosive environments such as coastal areas and chemical plants, it can also operate stably for long periods in damp underground environments.

Excellent Electromagnetic Shielding and Heat Dissipation: Aluminum alloy has good electrical and thermal conductivity, exhibiting excellent performance in electromagnetic shielding and heat dissipation. It effectively reduces signal interference, and through reasonable structural design, it can improve cable ventilation and extend equipment life.

Hot-dip galvanized cable trays are made of cold-rolled steel sheets and treated with a hot-dip galvanizing process.

They offer excellent corrosion resistance: the thick zinc layer forms a dense zinc-iron alloy that effectively resists corrosion from the atmosphere, soil, and chemicals, allowing for long-term use even in salt spray environments.

They have high mechanical strength: the hot-dip galvanizing process improves the mechanical properties of the cable tray, giving it high load-bearing capacity and compressive strength, ensuring safe cable transmission.

They have a long service life: under normal circumstances, hot-dip galvanized cable trays can last for more than 15 years, reducing the cost and hassle of frequent replacements.

Fire resistant cable trays are cable trays with fire-resistant boards as the core protective layer. They primarily utilize the heat insulation and flame-retardant properties of the fire-resistant boards to protect cables from fire.

Core Fire-Resistant Layer: The inner layer is wrapped with fire-resistant boards. These boards are non-combustible, high-temperature resistant, and have low thermal conductivity. They are typically 5-12 mm thick and effectively block flames and high temperatures.

Fire Resistance Rating: Can reach N1 (fire resistance for 60 minutes)

Powder-coated cable trays, based on traditional metal cable trays, undergo a high-quality powder coating process, resulting in excellent corrosion resistance, rust prevention, and weather resistance. Their open structure ensures good heat dissipation for cables, enhances current carrying capacity, and facilitates cable addition, removal, and maintenance, leading to high maintenance efficiency and low cost. They are widely used in industrial plants, commercial buildings, power and telecommunications facilities, providing reliable protection and management solutions for cable laying.
