Cold-formed steel framing inguva yakasimba, yakavimbika uye inodhura-inoshanda kune yakaderera-kukwira uye yepakati-inosimuka mapurojekiti ekuvaka.Zvinowanzo reva kuvakwa kwechiedza-chigadziriso apo zvakadzika uye zvakachinjika zvimiro zvemukati zvinonyanya kuumbwa nehurongwa hwenhengo dzinodzokororwa.Nhengo dzekugadzira dzinowanzo kupatsanurwa pa 16 kana 24 inches pakati, paine misiyano yepakati ichidzika nepamusoro zvichienderana nekuremerwa uye zvivharo.
Nhengo dzemadziro dzinowanzo vertical lipped chiteshi "stud" nhengo, iyo inokodzera mune isina kuvharwa chiteshi "track" zvikamu kumusoro uye pasi.Magadzirirwo akafanana anoshandiswa kune ese ari maviri epasi joist uye rafter magungano, asi mune yakachinjika application yepasi, uye yakachinjika kana yakatsetseka application yekumisikidza denga.Zvimwe zvinhu zvegadziriro yekugadzira zvinosanganisira zvisungo uye zvinobatanidza, mabhureshi uye bracing, zvimedu uye zvinobatanidza.Cold-formed simbi pasi uye matanda edenga anowanikwawo kune inotonhora-yakaumbwa simbi yekuumba maapplication.
Cold-formed steel inoreva nzira yekugadzira iyo simbi-yakavharwa sheet simbi inokungurukira-inoumbwa kuita zvigadzirwa senge matudhi, joists, track, misoro, makona, nhengo dzetruss nezvimwe zvinhu.Pakugadzira simbi inotonhora, ukobvu hwezvinhu hwakajairwa hunobva pa0.0147 mukati (0.373 mm) kusvika pa1/8 mukati.
