钢材重量和计算方法(国外英文资料) Basic knowledge of steel --- steel weight and method of calculation: examination major December 8, 2008 [examination big: China education examination first portal] simulation examination room, video course, steel weight 1. the theoretical weight of the steel, the theoretical weight of the steel is calculated by the nominal size of the steel and the density (formerly called the specific weight). The weight is called the theoretical weight. This is directly related to the length, size, sectional area and allowable deviation of the size of the steel. Because of the allowable deviation of the steel in the manufacturing process, the theoretical weight calculated by the formula is different from the actual weight, so it is only used as a reference in the estimation. The actual weight of 2. steel steel refers to the actual weight of steel in the actual weighing (weighing) - the test | weight, called actual weight. The actual weight is more accurate than the theoretical weight. Gross weight calculation method of the 3. steel weight is the net symmetry, the total weight of the steel itself and packaging material together. The transport enterprise calculates the freight by gross weight. But the purchase and sale of steel is calculated by net weight. The net is gross symmetry. The gross weight of the steel minus the weight of the packing material, that is the actual weight, is called net weight. In the purchase and sale of steel, it is usually calculated in net weight. The tare weight of steel packaging materials, called tare. The unit weight weight ton steel by using gross weight of freight. The legal unit of measurement for (1000kg), there are tons of tons (Imperial unit of weight ton (US 1016.16kg), a unit of weight 907.18kg). The charge weight also known as the ton or freight ton. The transportation department charged for shipping steel weight. There are different calculation standards and methods for different transportation modes. Such as the railway v
