各種直徑鋼筋的每米重量表(千克):?? 4mm:0.099??6mm:0.222? ?6.5mm:0.26 ?8mm:0.395? ?10mm:0.617??12mm:0.888??14mm:1.208??16mm:1.578? 18mm:1.998? ?20mm:2.467? ?22mm:2.986? 25mm:3.853??26mm:4.170??28mm:4.834?? 30mm:5.549??32mm:6.313??34mm:7.130??35mm:7.552??36mm:7.990??38mm:8.900? ?40mm:9.870? 不同直徑的鋼筋每延米的重量等于0.00617乘鋼筋直徑的平方。比如:22mm鋼筋每延米的重量=0.00617*22*22≈2.986Kg/m。 |
