Iziphethu ezifakwe i-zinc-galvanized zingaphansi kwenqubo ye-hot-dip galvanization.Le nqubo ihilela ukucwiliswa kwesiphethu sensimbi ku-vat ye-zinc encibilikisiwe emazingeni okushisa aphakeme kakhulu.
Abantu abaningi bakhetha iziphethu ze-torsion enazinki ngenxa yokumelana kwazo okumangalisayo nokugqwala nokugqwala, sibonga kakhulu ngenqubo yokufaka amadiphu ashisayo.Ngaphandle kosongo oluqhubekayo lokwakheka kokugqwala, iziphethu ezifakwe u-zinc zinikeza impilo ende kunemithombo eminingi efutheke uwoyela.
