  商家默认标准:直径乘以直径乘0.00617   其他:     方钢     W=0.00785乘边长的平方   扁钢：W＝0．00785×宽×厚   钢板   W＝7．85×宽×厚     钢管：W＝（外径-壁厚）×壁厚×0．02466   渡锌类：W＝原理论重量×1．06）             ρ≈d2×0.617     （ρ——线密度，单位kg/m；d——钢筋直径，单位cm）           例：φ20的线密度为：2×2×0.617＝2.468   。           工字钢规格重量表「2」     工字钢型号                 尺寸（mm）                                       截面面积                   重量                               高
