How much weight can galvanized steel cable trays bear
Hot-Dip Galvanizing (HDG) coatings typically add 0. 5 kg/m² to surface area, increasing base weight by 2–4%. Calculation: Calculation: Cover Weight (kg) = Material Density (kg/m³) × Cover Width (m) × Cover Thickness (m) × Cover Length (m) Tray rated for 50 kg/m is. Ladder cable tray is available in widths of 6, 9, 12, 18, 24, 30, 36, 42 and 48 inches with rung spacings of 6, 9, 12 or 18 inches. Note that wider rung spacings and wider cable tray widths decrease the overall strength of the cable tray. Specifiers should be aware that some cable tray. Let's assume the following specifications for a galvanized steel channel tray: Using the formula: Weight per meter (Wm)= (100+50)×1. This. us-trations without notice.
