鍍鋅鋼絞線通常指用于承力索(messenger wire)、拉線(guy wire)、加強(qiáng)芯(core wire or strength member)等，也可以作為架空輸電的地線（earth wire/ground wire）、公路兩邊的阻攔索(barrier cable)或建筑結(jié)構(gòu)中的結(jié)構(gòu)索(structure cable)。預(yù)應(yīng)力鋼絞線中常用的預(yù)應(yīng)力鋼絞線為無鍍層的低松弛預(yù)應(yīng)力鋼絞線(uncoated steel strand for prestressed concrete)，也有鍍鋅的(galvanized)，常用于橋梁、建筑、水利、能源及巖土工程等，無粘結(jié)預(yù)應(yīng)力鋼絞線(unbonded steel strand or monostrand)常用于樓板、地基工程等。
