Kuj tseem hu ua lub kaum sab xis hlau lossis lub kaum sab xis, cov kaum sab xis steel yog cov khoom tiav steel ua los ntawm kub-forming semi-tiav carbon steel. Raws li cov ces kaum steel feem ntau yog siv los muab cov qauv kev txhawb nqa, qhov zoo tshaj plaws muaj pes tsawg leeg yog cov hlau tsis tshua muaj, tsis tau muaj zog steel nrog zoo ductility thiab toughness. Nrog rau qhov no hauv siab, kev siv cov kaum sab xis sib txawv tuaj yeem sib txawv ntawm txoj kev choj, warehouses, khoom tsim khoom, kev txhawb nqa thav duab, rhawv, lossis cov tsheb thauj khoom.
Txawm hais tias lub kaum sab xis steel raug suav tias yog qhov yooj yim tshaj plaws ntawm cov yob-tsim steel, lawv muab cov txiaj ntsig zoo, tshwj xeeb tshaj yog thaum nws los txog rau framing, reinforcement, aesthetic trims, brackets, thiab lwm yam. Ua ke nrog cov khoom muaj txiaj ntsig ntawm cov hlau tsis tshua muaj hlau, cov kaum sab xis no tau ua ib feem txhim khu kev qha los yog cov khoom siv, nyob ntawm kev siv.
