Lesi sihloko sethula izindlela zokwelapha ezine ezivamile zamabhawodi: enamathela, i-hot-dip galvanizing, i-electroplating, futhi Dacro. Lezi zindlela zingathuthukisa ukumelana nokugqwala nokubukeka kwamabhawodi. Ukugqoka kanye ne-electroplating kungenza ingaphezulu lebhawodi libe bushelelezi futhi libe lihle kakhulu, kodwa azihlali isikhathi eside futhi ziklwebheka kalula; i-hot-dip galvanizing kanye ne-Dacro ingathuthukisa ikhono le-anti-corrosion, kodwa ubuso abubuhle ngokwanele. Manje kunefomula yamahhala ye-chromium ehexavalent ye-Dacro, okuyinto ehambisana nemvelo. Lesi sihloko sethula kafushane izinzuzo nezingozi zendlela ngayinye yokwelapha, kanye nokubaluleka kwazo.
