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 −. Find the volume of the cable tray: This depends on the dimensions (width, height, thickness) and length of the tray.
