鍍鋅鋼絞線通常指用于承力索(messenger wire)、拉線(guy wire)、加強芯(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)或建筑結構中的結構索(structure cable)。預應力鋼絞線中常用的預應力鋼絞線為無鍍層的低松弛預應力鋼絞線(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，無粘結預應力鋼絞線(unbonded steel strand or monostrand)常用于樓板、地基工程等。
