Cold-formed steel yog hais txog kev siv daim hlau los yog sawb khoov rau hauv lub xeev txias ntawm ntau qhov sib txawv ntawm cov hlau tiav.Cold-formed steel yog ib qho kev lag luam yooj yim-walled steel cross-section, kuj hu ua txias-tsim steel profiles.Bending seem steel yog cov khoom tseem ceeb ntawm lub teeb steel qauv.Nws muaj qhov kub dov tuaj yeem tsim tau txhua yam ntawm nyias, tsim nyog cov duab thiab txoj kev hla ntu.

Cold-formed steel yog ib qho ntawm ntau hom hlau hauv ib qho, qee qhov dav ntawm lub sawb, nyob rau hauv qhov kub thiab txias txias los ntawm cov txheej txheem yob txheej txheem, thiab maj mam deformed, kom ua tau raws li qhov xav tau ntawm cov duab thiab qhov loj, thiab tom qab ntawd txiav mus rau hauv qhov tsim nyog qhov ntev.Cov khoom no yog txias-formed steel.Tau kawg, kuj muaj stamping, dabtsi yog khoov los yog lwm yam deformation txoj kev kos duab txias-tsim hlau.Tab sis txoj kev yob txoj kev yog tsim rau high-volume industrial ntau lawm, khoom zoo, ua cov nqi, ntau lawm efficiency unmatched los ntawm lwm txoj kev, yog tam sim no ib tug loj tsim ntawm txias-tsim steel technology.Yog hais tias chav tsev yog nruab nrog cov khoom siv vuam hauv (xws li cov vuam vuam, vuam, thiab lwm yam) tab sis kuj tseem tsim cov khoom txias-tsim steel ntu kaw.Cold-formed steel thiab welded steel qhov sib txawv tseem ceeb yog: welded steel kav tsuas yog siv rau kev xa cov kua dej xws li roj, dej.Roj, roj, ncu thiab lwm yam.Yuav tsum tau cov hlau kom tiv taus qee qhov siab, thiab txias-tsim steel yog siv los tsim cov qauv los tiv thaiv sab nraud quab yuam ntawm cov nqaj ntoo hla ntu, qhov ntev thiab cov khoom siv kho tshuab muaj qee yam yuav tsum tau ua.

Cold-formed steel tuaj yeem muab faib ua qhib profile steel thiab kaw profile steel pawg raws li cov qauv kev faib tawm.

(1) Kev qhib qhov txias-tsim steel equilateral lub kaum sab xis steel nrog tsis sib npaug sab, sab hauv thiab sab nraud curling curling lub kaum sab xis, equilateral thiab scalene channel, curling los yog sab ntug channel, Z seem steel, yob ntug Z seem steel, steel thiab lwm qhov tshwj xeeb zoo li qhib.

(2) kaw txias-tsim steel yog welded kaw tom qab txias-tsim steel-zoo li tus ntoo khaub lig seem, raws li cov duab ntawm round, square, rectangular thiab zoo li tus.
