Txheej txheem steelyog qeb ntawm cov hlau siv los ua cov khoom siv tsim kho hauv ntau yam ntawm cov duab. Ntau cov qauv steel hlau coj daim ntawv ntawm tus nqaj elongated muaj ib qho profile ntawm ib ntu cross. Cov qauv hlau hlau, qhov ntau thiab tsawg, tshuaj lom neeg, cov khoom siv neeg siv cov khoom siv xws li cov ua tau zoo, thiab lwm yam.
Feem ntau cov qauv hlau sib xws, xws li I-nqaj, muaj lub sijhawm thib ob, uas yog tias lawv muaj peev xwm txhawb nqa lub nraaj siab tsis muaj ntau yam sagging.
Cov duab muaj tau piav qhia nyob rau hauv ntau tus qauv luam tawm thoob ntiaj teb, thiab ntau tus kws tshaj lij thiab tus tswv thaiv kev hla tseem muaj.
Ib qho hlau i-nqaj, hauv qhov no siv los txhawb cov cav ntoo jobists hauv ib lub tsev

Qws, ib puag ncig lossis square ntu ntev piv rau nws qhov dav; kuj tseem rebar thiab dowel.
Phaj, cov ntawv hlau tuab dua li 6 hli lossis 1\/4 hauv.

Thaum ntau seem yog tsim los ntawm kub lossis txias dov, lwm tus yog tsim los ntawm vuam ua ke tiaj tus lossis bolling tshaj plaws phaj cia rau hauv lub voj voog thiab seam-welded).
Cov lusLub kaum pem teb, Channel Hlau, thiabSheet hlauTau siv ntau yam txij li ua ntej ua ntej w w w w w whought tau hloov los ntawm steel rau kev ua lag luam. Lawv tau nyob tom qab lub sijhawm ntawm cov hlau wrought wrought thiab tseem qee zaus hais tias lawv yog misnomers (sib piv "cov ntawv ci", tseem siv tsis tau rau cov ntawv ci txhuas ntawv). Nyob rau hauv daim ntawv sau rau kev sib cav ua haujlwm, cov ntsiab lus raug zoo liLub kaum sab, Channel Tshuag, thiabdaim ntaubsiv.
thiab tom qab ntawd tsau nrog txiv ntoo thiab bolts. Kev nro daim hlau thiab lwm txoj hlua hlau kuj tseem muaj rau ntxiv lub zog rau cov qauv ua tiav.
