Ake sihlole inkinga yokugqwala kwensimbi yesimo sezulu ngokuningiliziwe. Ungqimba oluvikela ukugqwala olwakha ensimbini yesimo sezulu luphephile ezitshalweni, hhayi nje kuphela ngoba amanani ensimbi, i-manganese, ithusi ne-nickel awanabo ubuthi, kodwa futhi ngoba lezi zakhi zokulandelela zibalulekile ekukhuleni kwezitshalo ezinempilo. Isembozo sokuzivikela esakhiwe ngensimbi siwusizo kulokhu.
Kodwa-ke, ezinye izifundo zokwakha ziphakamisa ukuthi ukusetshenziswa kakhulu kwensimbi yesimo sezulu A kungase kube ukungcola kwemvelo ngaphansi kwezimo ezisheshisa inqubo yokugqwala. Qaphela ukuthi lezi zifundo azihlangene ne-Weathering STEEL B noma i-Redcor, eyenza imibhede yezinyoni. Okunye okuphawulekayo ngalolu cwaningo ukuthi lwenzeka phambi kwebhilidi elikhulu ngemuva kweminyaka yokuchayeka. Ngakho inani elikhulu lensimbi yesimo sezulu A ingase ibe namakhemikhali ayingozi emvelweni. Kodwa ngamanani amancane insimbi yesimo sezulu ayinabo ubuthi ngaphansi kwezimo ezifanele zemvelo.
Ngokuthuthuka kongqimba bokugqwala, amandla aqinile kanye nokumelana nokugqwala kwensimbi enesimo sezulu ye-CORT-Ten B kuya ngokuya kukhuphuke. Labo abahlala ezindaweni ezitholakala kalula ukugqwala komkhathi (ngenxa yezimo zemvelo) bangavumela insimbi yesimo sezulu ukuba ifinyelele umbala wabo wokugqwala abawufisayo bese besebenzisa izinto zokuvala ukuze zisize ukugcina umbala olungile nobuqotho besakhiwo.
Lokho abantu abaningi abakhathazeke ngakho kakhulu ngezinsimbi zesimo sezulu ukuqina kwazo. Endaweni efanele, emibhedeni ephakanyisiwe, insimbi ye-CORT-TEN imelana nokugqwala. Yingakho ngaphambi kokuba isetshenziselwe amaphrojekthi we-horticultural, le nsimbi yakhethwa izakhiwo nezakhiwo zokwakha (imibhoshongo yokusakaza e-UK, isibonelo).
Nokho, lokhu kumelana kuncike kakhulu esimweni sezulu nesimo sezulu sendawo. I-oxidation efanele iyenzeka ngesikhathi somjikelezo wokumanzi/womile. Ezindaweni ezinomswakama ophezulu, ukuqina kwensimbi ye-CorT-Ten kungaba nenselele. Ngaphezu kwalokho, ukumelana nokugqwala kuphansi ezindaweni ezinenkungu kasawoti, okungukuthi, izindawo ezisogwini. Abantu abahlala ogwini lolwandle bathola amazinga aphezulu okugqwala emibhedeni yabo yensimbi ye-COR.
Kungakho abantu abahlala kulezi zimo zomoya kufanele bakhethe imibhede yensimbi eyenziwe nge-aluminium efakwe ngothayela esikhundleni sokukhetha imibhede yensimbi eyodwa koyedwa njenge-Birdies Original 6. Ngokujabulisayo, insimbi yamagalani nayo iphephile ezingadini!
Kodwa-ke, izendlalelo zensimbi ezishintshashintshayo zichayeke enkunguni, eqhweni, emvuleni, noma kwezinye izimo eziswakeme zizovikelwa ukugqwala okwakhiwa endaweni engaphezulu yama-alloys akha insimbi yesimo sezulu. Banenzuzo eyengeziwe yokuba nesitayela esihlukile sombala embotsheni yokuzivikela.
