Sivelisa uluhlu olupheleleyo lweemveliso ze-corten steel edge edge ekulula ukuzifaka, ezithandekayo, ezinxitywayo kunye nezifikelelekayo. Nokuba ufuna ukwenza indawo yengca ecacileyo, egoqwe ngqo ekulula ukuyigcina, okanye uthotho lweentyatyambo ezigobileyo ezigobileyo, ungakwenza oku ngokukhawuleza, ngokulula nangexabiso eliphantsi usebenzisa isisombululo segadi yentsimbi ye-AHL engaphantsi komhlaba nangaphezulu.
Ngeminyaka yee-1930, i-US Steel yenza i-Steel alloy yokusetyenziswa ngaphandle engayifuni ipeyinti. Yayibizwa ngokuba yiCorten steel. Imiphetho yegadi eyenziwe kwintsimbi ye-alloy efanayo yinxalenye ebalulekileyo yoluhlu lwemveliso yethu. Intsimbi yenzelwe ukufumana i-patina ekhangayo ngexesha elifutshane, kwaye le rust surface inokukhusela ngokwenene intsimbi ekuqhubeni ukubola. Usebenzisa isinxibo sethu sentsimbi esinemozulu entle, unokwenza iibhedi ezintle zeentyatyambo, iindawo ezinengca, iindlela zegadi kunye neendawo ezingqonge imithi ezimelana novavanyo lwexesha. Yonke imiphetho yegadi yethu eguquguqukayo iza newaranti yeminyaka eyi-10, kodwa ngokugcinwa okuncinci kunye nokuqwalaselwa, kufuneka ihlale ikwimeko entle ixesha elide kunoko: mhlawumbi iminyaka engama-30 okanye engama-40!
