Product Definition Aluminum alloy tray type cable tray is made of aluminum magnesium silicon alloy sheet metal that is CNC integrated and bent into shape. The bottom plate is stamped with heat dissipation waist holes, and the two sides are equipped with high blocking edges. It has a semi transparent tray structure and is matched with aluminum alloy cover plates of the same material and a complete set of aluminum connectors. It takes into account heat dissipation, cable full bottom support, lightweight, explosion-proof and rust prevention. It is a universal cable tray for indoor humid, explosion-proof and high-rise suspended ceiling strong and weak electricity mixed wiring. Mainstream materials: 1.6063-T5 universal model, high cost performance, suitable for use in computer rooms, underground garages, and inland areas with mild humidity; 2.6061-T6 enhanced version, with higher strength, specifically designed for large-span and heavy-duty cables with a span of over 3m; 3.1060 pure aluminum version, good rust prevention, only suitable for short distance branch lines in clean workshops. Ⅱ. Complete production process flow 1. Integrated tray forming: aluminum alloy coil cutting and bending, bottom plate stamping heat dissipation holes, heavy-duty bottom with longitudinal reinforcement ribs; Reserved connection and lifting holes on the side panel, matched with cover plates, bends, 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: Unified aluminum alloy for connectors, brackets, and bolts; Insulation gaskets must be added to the carbon steel bracket to prevent 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. Balanced heat dissipation and protection, with the strongest universality. The bottom plate is perforated for ventilation, and cables do not slip off. It is suitable for mixed strong and weak electrical wiring; 2. 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%; 3. An aluminum oxide rust proof film is formed on the surface, which prevents rusting in damp underground areas and riverside factories for a long time. Cutting sections do not require zinc rich repair paint; 4. 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; 5. 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; 6. The semi open structure is easy to maintain, and adding partition plates can achieve strong and weak current zoning, making construction flexible; 7. The appearance is matte and clean, with 100% recyclable aluminum and no rust residue, suitable for sterile clean workshops in food and medicine. Ⅴ. Applicable scenarios 1. Comprehensive wiring of strong and weak electricity in high-altitude ceilings of airports, high-speed railway stations, and high-rise office buildings; 2. Power distribution in underground garages, underground pipe trenches, and slightly damp inland riverbank areas; 3. Flammable and explosive wiring areas such as oil and gas warehouses and dust explosion-proof workshops; 4. Photovoltaic and distribution rooms, while laying high-voltage power cables and instrument control lines; 5. Power distribution lines for roofs and outdoor factory areas in northern cold regions; 6. Dry food, pharmaceutical sterile clean workshops, and medium span factories within 3 meters. Ⅵ. Key points of construction and installation specifications 1. Insulation gaskets must be installed to prevent electrochemical corrosion when aluminum alloy bridge frames come into contact with carbon steel brackets and bolts; 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 laying with a length exceeding 30m to counteract thermal expansion and contraction deformation; 4. Aluminum alloy partition plates must be installed on the same tray for strong and weak electricity, and sealed cover plates must be covered throughout the dust and outdoor areas; 5. The single span should not exceed 3m, and thicker versions should be used for long spans with heavy loads, with a deflection of ≤ L/200; 6. On site cutting and polishing should be smooth, and aluminum specific anti-corrosion varnish should be lightly applied in heavy humid environments. Zinc rich paint is prohibited; 7. Install fireproof sealing materials at the locations of through walls and floor slabs to block the spread of flames and smoke; 8. All explosion-proof areas use aluminum alloy fittings, and it is prohibited for carbon steel fasteners to be exposed and collide to produce sparks.
