1. According to the industry standard YBT4159-2007, the lentil-shaped pattern plate in hot-rolled patterned steel plates and steel strips is 40.1Kg per square meter. Calculate 1.25 meters * 6 meters * 40.1Kg = 300.75Kg. The theoretical delivery weight can be used.
2. Based on actual experience, the theoretical calculation formula of flat plates can be applied, 5.0*1.26*6*7.85=294.375Kg. This method is only suitable for calculating the approximate weight and does not serve as a basis for delivery.
