Grenada Aluminum Alloy Cable Tray Specifications

Grenada Aluminum Alloy Cable Trays are typically made from 6063-T6 aluminum alloy, designed for high strength, corrosion resistance, and versatile cable management applications.Material and AlloyGrenada cable trays use 6063-T6 aluminum alloy for both longitudinal members and transverse rungs, providing excellent corrosion resistance, mechanical strength, and lightweight properties suitable for indoor and outdoor environments . The alloy is extruded to form channels or I-beams for ladder-type trays, ensuring durability and structural integrity .Structural DesignTray Types: Ladder, solid-bottom, and ventilated trays are available. Ladder trays feature extruded aluminum channels with welded or clinched rungs .Rung Spacing: Transverse members (rungs) are typically spaced at 9, 12, or 18 inches to support cable loads and prevent sagging .Rung Design: Rungs are extruded from 6063-T6 aluminum and designed to prevent moisture or contaminant accumulation .Load Capacity: All tray sections support an additional 200 lb concentrated load beyond the published load class, with a 1.5 safety factor for standard spans .DimensionsLongitudinal Members: Depths range from 4-1/2 to 10 inches for aluminum ladder trays .Width: Tray widths are selected based on cable capacity requirements, commonly 12 to 42 inches .Rung Size: Extra-wide rungs are welded to side rails, with every second rung reversed for easy cable tie or clamp installation .Installation and AssemblySplice Connections: High-pressure bolted splice connectors with a minimum of four bolts per connector; resistance across splice connections does not exceed 330 microhms .Fittings: Continuous arc fittings with radii of 12, 24, 36, or 48 inches maintain the same load capacity as straight sections .Surface Finish: Smooth, rounded edges and welds prevent cable damage during installation .Environmental and Performance ConsiderationsCorrosion Resistance: The 6063-T6 aluminum alloy provides excellent resistance to atmospheric corrosion and stress cracking .Deflection: Continuous spans may reduce deflection by up to 50%; deflection factors are provided for lighter loads to calculate tray performance .Compliance: Designed to meet CSA, NEMA, and ASTM standards for cable tray systems . Grenada Aluminum Alloy Cable Trays are engineered for robust, lightweight, and corrosion-resistant cable management, suitable for industrial, commercial, and outdoor installations, with flexible options for load, width, and environmental conditions.
