izinqwaba zamashidi ensimbi zisetshenziswa kabanzi emikhakheni eminingi njengokwesekwa komgodi wesisekelo, ukuqinisa ibhange, ukuvikela izindonga zasolwandle, ukwakhiwa kwe-wharf kanye nobunjiniyela obungaphansi komhlaba. Ngenxa yomthamo wayo omuhle kakhulu wokuthwala, ingakwazi ukubhekana ngokuphumelelayo nokucindezela kwenhlabathi nokucindezela kwamanzi. Izindleko zokukhiqiza inqwaba yeshidi lensimbi eligoqelwe ngokushisayo liphansi uma kuqhathaniswa, futhi lingasetshenziswa kabusha, futhi linomnotho omuhle. Ngesikhathi esifanayo, insimbi ingaphinda isetshenziswe kabusha, ngokuhambisana nomqondo wentuthuko esimeme. Nakuba inqwaba yeshidi lensimbi eligoqelwe ngokushisayo inokuqina okuthile, kwezinye izindawo ezigqwalile, ukwelashwa okunqanda ukugqwala okufana nokunamathiswa nokufaka ama-hot-dip galvanizing kuvame ukusetshenziselwa ukuqhubeka nokwelula impilo yesevisi.
