1、外型不一樣，圓鋼外型光圓，無紋無肋，其它鋼筋表面外型有刻紋或有肋.這樣就造成圓鋼與混凝土的粘結力小，而其它鋼筋與混凝土的粘結力大。 2、成份不一樣，圓鋼(一級鋼)屬于普通低碳鋼，其它鋼筋多為合金鋼。 3、強度不一樣.圓鋼強度低，其它鋼強度高，即直徑大小相同的圓鋼與其它鋼筋相比，圓鋼所能承受的拉力要比其它鋼筋小，但圓鋼的塑性比其它鋼筋強，即圓鋼在被拉斷前有較大的變形，而其它鋼筋在被拉斷前的變形要小得多。圓鋼應用前景廣闊，被普遍用于五金，建筑，汽車、造船、石化、機械、醫(yī)藥，昆明鍍鋅圓鋼型號、食品、電力、能源、航天等、建筑裝潢。相當普遍的普通機械零件加工，昆明鍍鋅圓鋼型號，一般的桿類鋼件，CD桿，昆明鍍鋅圓鋼型號、螺栓、螺母。
