1, angle steel: weight per meter = 0.00785 × (side width + edge width - edge thickness) × edge thickness
2, round steel: weight per meter = 0.00617 × diameter × diameter (rebar and round bar the same)
3, flat steel: weight per meter = 0.00785 × thickness × as wide
4, square steel: weight per meter (kg) = 0.00785 × edge width × width
Five, six angle steel: weight per meter (kg) = 0.0068 × distance × edge-to-edge distance
Octagonal steel: weight per meter (kg) = 0.0065 × distance × edge-to-edge distance
7, steel: weight per meter (kg) = 0.00617 × diameter × diameter
8 in thick steel plate: Weight per meter (kg) = 7.85 × thickness
9, sheet steel: weight per meter (kg) = 7.85 × thickness
10, seamless steel: weight per meter (kg) = 0.02466 × wall thickness × (OD - Wall Thickness)
11, steel pipe joints: Weight per meter (kg) = 0.02466 × wall thickness × (OD - Wall Thickness)
12, yellow brass: weight per meter = 0.02670 × wall thickness × (OD - Wall Thickness)
13, copper tube: weight per meter = 0.02796 × wall thickness × (OD - Wall Thickness)
14, Aluminum Diamond Plate: weight per square meter = 2.96 × thickness
15, the proportion of non-ferrous metals: copper plate 8.5 8.9 yellow copper zinc plates 7.2 stereotype 11.37
16, non-ferrous metal sheet is calculated as: weight per square meter = proportion of x thickness (www.dbgtzx.com edit)
