Approximate theoretical weights are calculated using a 97 mm developed strip width and a steel density of 7,850 kg/m³. Slotted-channel calculations assume approximately 60 obround slots per 3 m length. Actual finished weight may vary with dimensional tolerances, bend radii, slot quantity and surface treatment. Please confirm production weight before ordering.
