1.Izindleko zokwelashwa eziphansi: Izindleko zokugalela idiphu elishisayo ziphansi kunezinye izimbobo zikapende.
2.Okuhlala isikhathi eside: Idiphu elishisayoinsimbi eyi-galvanized angle ironinezici zokucwebezela kwendawo, ungqimba lwezinc olufanayo, akukho ukuvuza, akukho ukushelela, ukunamathela okuqinile nokumelana nokugqwala okuqinile.Endaweni engaphansi kwedolobha, ukushuba okujwayelekile kwe-hot-dip galvanized rust-proof kungagcinwa iminyaka engaphezu kwengama-50 ngaphandle kokulungiswa;ezindaweni zasemadolobheni noma ezingasogwini, ukujiya okujwayelekile kongqimba oluvikela ukugqwala okushisayo kungagcinwa iminyaka engama-20.Ayidingi ukulungiswa.
3.Ukuthembeka okuhle: Isendlalelo esinezinsimbi siyisibopho se-metallurgical nensimbi futhi siba yingxenye yendawo yensimbi, ngakho-ke ukuqina kokunamathela kunokwethenjelwa kakhulu.
4.I-coating inokuqina okuqinile: ungqimba lwama-galvanized lwakha isakhiwo esikhethekile se-metallurgical, esingamelana nokulimala komshini ngesikhathi sokuthutha nokusetshenziswa.
5.Ukuvikelwa okuphelele: Yonke ingxenye yengxenye ehlanganisiwe ingafakwa uthayela, ngisho nasekucindezelekeni, ekhoneni elicijile nendawo ecashile ingavikelwa ngokugcwele;
6.Ukonga isikhathi nokugcinwa komsebenzi: inqubo yokufaka uthayela ishesha kunezinye izindlela zokwakha zokumboza, futhi ingagwema isikhathi esidingekayo sokudweba esizeni ngemva kokufakwa.
