1, iindleko zonyango eziphantsi: iindleko zokuthintela umhlwa oshushu nge-galvanized dip ziphantsi kuneendleko zezinye iingubo zepeyinti;
2, eqinileyo: ishushu-idiphuibha ye-engile yentsimbi egalelweyoineempawu zokukhazimla komphezulu, umaleko we-zinc ofanayo, akukho kuvuza, akukho drip, inamathela ngamandla, ukumelana nokugqwala okunamandla, kwindawo engqongileyo yasezidolophini, ubukhulu obuqhelekileyo bokuthintela umhlwa obugqunywe nge-hot-dip galvanized bunokugcinwa iminyaka engaphezu kwama-50 ngaphandle kokulungiswa; Kwiindawo zasezidolophini okanye ezikude nolwandle, umaleko oqhelekileyo ogqunywe nge-hot-dip galvanized anti-rust unokugcinwa iminyaka engama-20 ngaphandle kokulungiswa;
3, ukuthembeka okulungileyo: umaleko we-galvanized kunye nentsimbi zidibene ne-metallurgical, ziba yinxalenye yomphezulu wentsimbi, ngoko ke ukuqina kwengubo kuthembeke ngakumbi;
