Product Definition Aluminum alloy trough type cable tray is made of aluminum magnesium silicon alloy plate, which is bent into a fully enclosed U-shaped trough body. It is equipped with aluminum alloy cover plate of the same material and a complete set of aluminum alloy connectors. It relies on the natural aluminum oxide film of aluminum for long-term rust prevention. The fully enclosed structure comes with electromagnetic shielding, light weight, good heat dissipation, and no spark explosion when impacted. It is a special wiring carrier for lightweight engineering, precision weak electricity, high-rise ceilings, and explosion-proof workshops. Mainstream materials: 1.6063-T5 universal model, high cost-effectiveness, suitable for indoor use, mild humidity, and weak electricity in computer rooms; 2.6061-T6 enhanced version, with higher strength, specifically designed for large-span and heavy-duty cables with a span of over 4m; 3.5052 thin plate version, good plasticity, small clean workshop trunking branch line. Ⅱ. Complete production process flow 1. Integrated bending forming: Aluminum alloy coil is CNC cut and bent into a closed U-shaped groove, and the bottom can be reinforced with reinforcing ribs. It is matched with cover plate, bent through, and three-way argon arc welding forming; Thickness 1.2-2.5mm, width 600mm or more ≥ 1.5mm, single section 2m/4m, customizable 6m extension. 2. Surface anti-corrosion treatment: ① Anodizing (standard, film thickness 10-15 μ m, resistant to weak salt spray); ② Powder coating, multi-color decoration; ③ Fluorocarbon spray coating, high weather resistance outdoors. 3. Accessory matching: The connectors, support arms, and bolts are made of unified aluminum alloy, and insulation gaskets are installed on the aluminum steel contacts to avoid electrochemical corrosion. Ⅲ. Complete set of aluminum alloy matching accessories 1. Direct accessories: thickened aluminum alloy connecting pieces, aluminum alloy bolts, stainless steel grounding braided tape; 2. Irregular turning parts: 90 °/45 ° horizontal bending, vertical up and down bending, tee, four-way, reducing diameter; 3. Functional accessories: split sealed aluminum alloy cover plate, aluminum alloy metal partition plate, fireproof partition board; 4. Support system: Same material aluminum alloy support arm, aluminum alloy column, seismic support hanger. Ⅳ. Seven core advantages 1. The self weight is only one-third of that of steel, greatly reducing the load-bearing capacity of ceilings and roofs, making manual installation effortless, and increasing construction efficiency by 40%; 2. An aluminum oxide rust proof film is formed on the surface, which prevents rusting in damp underground areas and riverbank factories for a long time. The cut surface does not require repair of anti-corrosion paint; 3. The all aluminum sealed chamber has excellent electromagnetic shielding, protecting highly sensitive weak current lines such as communication, instruments, and optical fibers; 4. The thermal conductivity is 5 times that of steel, which can quickly dissipate the heat of the cable and reduce the temperature rise during cable operation; 5. Aluminum impact has no sparks, is naturally explosion-proof, and can be directly used in workshops where oil, gas, and dust are flammable and explosive; 6. It does not crack at low temperatures of -40 ℃, and has a stable structure in harsh outdoor environments in the north. It is equipped with expansion joints to eliminate thermal expansion deformation; 7. The appearance is matte and clean, with 100% recyclable aluminum material and no rust residue, suitable for clean workshops. Ⅴ. Applicable scenarios 1. Communication and self-control weak current backbone in data centers, hospitals, and office building computer rooms; 2. Underground parking garage, underground pipe trench, and slightly damp inland riverbank factory area; 3. Flammable and explosive explosion-proof wiring areas such as oil and gas warehouses and dust workshops; 4. Lightweight wiring for high-altitude large-span suspended ceilings in airports, high-speed railway stations, and exhibition centers; 5. Rooftop and outdoor distribution lines in cold northern regions; 6. Power distribution for dry food clean workshops and medium span factories within 3 meters. Ⅵ. Key points of construction and installation specifications 1. Insulation gaskets must be installed when aluminum alloy comes into contact with carbon steel brackets and bolts to prevent electrochemical corrosion; 2. Each section of the bridge is grounded with a stainless steel braided strip, and the overall grounding resistance is ≤ 4 Ω; 3. Install aluminum alloy expansion joints for outdoor installations exceeding 30m in length to counteract thermal expansion and contraction; 4. Install aluminum alloy separators in the same slot for strong and weak electricity, and seal and cover the entire process with a cover plate; 5.6063-T5 single span shall not exceed 3m, and 6061-T6 thickened version shall be selected for long span heavy load, with deflection ≤ L/200; 6. Smooth the cutting section on site and lightly apply aluminum specific anti-corrosion varnish to damp areas; 7. Install fire-resistant sealing for wall and floor openings to block the spread of flames and smoke; 8. All explosion-proof areas use aluminum alloy fittings, and it is prohibited to expose carbon steel fasteners for impact.
