<p>Disclosed is a color cable tray system made of an aluminum alloy. The color cable tray system includes a straight section assembled with various accessory parts in order to support cables. The straight section includes a side rail having a "D"-shaped structure for enhancing a load strength and a lateral tensile strength thereof and including a "D "-shaped upper part, a plurality "D"-shaped corrugated parts, which alternately protrude from a vertical part of the side rail in opposition to each other, a T-shaped wing part formed at a lower end portion of the vertical part and a middle wing part integrally formed with an inner sidewall of the vertical part; and a rung having a rectangular pipe shape, in which an inner portion of the rung is empty, and including upper and lower surfaces formed with at least one corrugated part, lateral surfaces formed with at least one corrugated part, and a partition wall installed in the rung while extending from the upper surface to the lower surface of the rung and having a circular screw receiving section formed at a center portion of the partition wall. A plurality of rungs are inserted between lower portions of two side rails with a uniform interval and fixedly coupled to the side rails by means of screws. A plurality of straight sections made of an aluminum alloy are assembled with each other, thereby forming the color cable tray system.</p> |
