Sikhiqiza uhla olugcwele lwemikhiqizo yonqenqema lwengadi ye-corten steel okulula ukuyifaka, ejabulisa ngobuhle, egqokekayo futhi ethengekayo. Kungakhathaliseki ukuthi ufuna ukwakha indawo yotshani ecacile, eqondile futhi kulula ukuyinakekela, noma uchungechunge lwemibhede yezimbali egobile, ungakwenza lokhu ngokushesha, kalula futhi ngeshibhile usebenzisa isisombululo semiphetho yengadi yensimbi ye-AHL engaphansi komhlaba nangaphezulu.
Ngawo-1930, i-US Steel yakha i-Steel alloy ukuze isetshenziswe ngaphandle eyayingadingi upende. Yaqanjwa ngokuthi i-Corten steel. Imiphetho yengadi eyenziwe ngensimbi ye-alloy efanayo iyingxenye ebalulekile yohlu lwemikhiqizo yethu. Insimbi iklanyelwe ukuthola i-patina ekhangayo ngesikhathi esifushane, futhi lokhu kugqwala okungaphezulu kungavikela insimbi ekugqwaleni okwengeziwe. Usebenzisa insimbi yethu yokulungisa isimo sezulu, ungakha imibhede yezimbali emihle, izindawo ezinotshani, izindlela zasengadini kanye nezihlahla ezizungezile ezimelana ngempela nesikhathi. Yonke imiphetho yengadi yethu enesimo sezulu esibucayi iza newaranti yeminyaka eyi-10, kodwa ngokulungiswa nokunaka okuncane, kufanele ihlale isesimweni esihle isikhathi eside kunaleso: mhlawumbe iminyaka engama-30 noma engama-40!
