Calculation of weight of galvanized cable tray
This tool estimates tray self-weight from material density and an approximate metal volume. For solid and perforated trays, it treats the tray as a formed sheet: Developed sheet width per meter: Dev = W + 2H + 2R Metal volume per meter: V = Dev × t × 1 × (1 − Open%) Weight per meter:. Find the volume of the cable tray: This depends on the dimensions (width, height, thickness) and length of the tray. Now, let's look at the specifics of Cable Tray Weight Calculation for each tray type. Export results instantly for schedules, submittals, and field checks. Density values are typical engineering references. This is because the load capacity of the cable tray needs to be enough to support the cables, wires, and other items in its system. Our cable tray load calculator. Calculate NEC-compliant wire basket cable tray fill, load capacity, and hardware requirements for professional installations.
