Ngasekuqaleni kwalo nyaka, i-Wall Street Journal ikhombe amathrendi amathathu ekwakhiweni kwezwe ngokusekelwe emiphumeleni yocwaningo evela ku-National Landscape Professional Association. Izitayela ezintathu eziphawulekayo zihlanganisa ama-pergolas, ama-metal finishes angapholishiwe kanye nezici ezakhelwe ngaphakathi nemisebenzi eminingi. I-athikili iphawula ukuthi ukukhetha okudume kakhulu "kokuqedwa kwensimbi okungapholishiwe" insimbi yesimo sezulu.

Iyini i-Cor-Ten steel?

I-Cor-ten ® igama lohwebo lase-U.S. Steel lohlobo lwensimbi ekwazi ukumelana nokugqwala emkhathini evame ukusetshenziswa lapho kudingeka amandla aphezulu nezinto zomjikelezo wempilo omude. Lapho ibhekene nezimo ezihlukahlukene zomkhathi, insimbi ngokwemvelo yenza ungqimba lokugqwala noma ukugqwala kwethusi. Le patina yiyona evikela impahla ekugqwaleni okuzayo. Njengoba i-cor-Ten ® yaqala ukuduma, ezinye izigayo zokukhiqiza zaqala ukwakha insimbi yazo ekwazi ukumelana nokugqwala komkhathi. Isibonelo, i-ASTM igxile ekudaleni ukucaciswa okubhekwa njengokulingana ne-COR-TEN ® ezinhlelweni eziningi. Ukucaciswa okusebenzayo kwe-ASTM okusebenzayo yi-ASTM A588, A242, A606-4, A847, kanye ne-A709-50W.

Izinzuzo zokusebenzisa insimbi yesimo sezulu

I-athikili ye-Wall Street Journal iphawula ukuthi abaklami bendawo yangaleso sikhathi bakhetha "izindawo ezinkulu zensimbi ehlanzekile, engapholishiwe" kunomsedari nensimbi ekhandiwe. Umklami okukhulunywe ngaye esihlokweni wakuncoma ukubukeka kwe-patina yensimbi futhi wancoma ukuba usizo kwayo. I-patina ikhiqiza "ukuthungwa okuhle kwesikhumba esinsundu," esho, kuyilapho insimbi "iphikisana nokukhwabanisa" futhi idinga ukulungiswa okuncane.

Njenge-COR-10, insimbi yesimo sezulu inikeza izinzuzo ezibalulekile kunezinye izinsimbi zezakhiwo ezivezwe ezintweni zangaphandle, okuhlanganisa ukunakekelwa okuphansi, amandla aphezulu, ukuqina okuthuthukisiwe, ukujiya okuncane, ukonga izindleko kanye nesikhathi sokwakha esincishisiwe. Ngaphezu kwalokho, ngokuhamba kwesikhathi, ukugqwala okuvela ensimbi kuhlangana kahle nezingadi, amagceke, amapaki nezinye izikhala ezingaphandle. Ekugcineni, ukubukeka kobuhle bensimbi yesimo sezulu kuhlanganiswe namandla ayo, ukuqina nokuguquguquka kwavumela ukuthi isetshenziswe ezimeni ezingaphansi kwezinhle njengezindonga zikakhonkolo.

Ukusetshenziswa kwensimbi yesimo sezulu ekwakhiweni kwezwe nendawo yangaphandle

Njengomphakeli we-corten okulingana, i-Central Steel Service igxile ekusatshalalisweni kwemikhiqizo ye-corten ekhethekile elungele ukwakhiwa kwengadi, ukulungiswa kwezwe nezinye izinhlelo zokusebenza zangaphandle. Nazi izindlela eziyi-7 zokusebenzisa insimbi yesimo sezulu ekwakhiweni kokwakheka kwezwe kanye nezikhala zangaphandle:

Ukugaya emaphethelweni ezwe

Udonga olubambayo

Ibhokisi lokutshala

Uthango namasango

Ihlengethwa

Ukufulela nokuseceleni

Ibhuloho
