I-1, iindleko zonyango eziphantsi: iindleko zediphu eshushuIbha yeAngle yeCarbon Steelukuthintela kuphantsi kuneendleko zezinye iingubo zepeyinti;
I-2, ehlala ihleli: i-hot-dip galvanized Angle steel ineempawu zokucwebezela komphezulu, iyunifomu ye-zinc layer, akukho plating evuzayo, i-drip, i-adhesion eyomeleleyo, ukuxhathisa okuqinileyo kwe-corrosion, kwimeko ye-suburban, ubukhulu obuqhelekileyo bokuthintela umhlwa obushushu bunokugcinwa iminyaka engaphezu kwama-50 ngaphandle kokulungiswa; Kwiindawo ezisezidolophini okanye ezikude nonxweme, umaleko oqhelekileyo wokuchasa umhlwa ungagcinwa iminyaka engama-20 ngaphandle kokulungiswa;
3, ukuthembeka okulungileyo:ibha yentsimbi yentsimbikunye nentsimbi yindibaniselwano ye-metallurgical, ibe yinxalenye yendawo yentsimbi, ngoko ukuqina kwengubo kunokwethenjelwa ngakumbi;
I-4, ukuqina kwengubo yomelele: i-galvanized layer yakha isakhiwo esikhethekileyo se-metallurgical, esinokumelana nomonakalo womatshini ngexesha lokuthutha kunye nokusetyenziswa;
I-5, ukukhuselwa okubanzi: yonke inxalenye ye-plating inokuthi ifakwe nge-zinc, nakwi-depression, iikona ezibukhali kunye neendawo ezifihliweyo zinokukhuselwa ngokupheleleyo;
I-6, gcina ixesha kunye nomgudu: inkqubo ye-galvanizing ikhawuleza kunezinye iindlela zokwakha iingubo, kwaye ixesha elifunekayo lokupenda kwisayithi emva kokufakwa kunokugwenywa.
