Txias- cov khoom dov yog tsim los siv kub- dov coils ua raw khoom thiab dov ntawm qhov kub thiab txias - tshwj xeeb, hauv qab qhov kub ntawm recrystallization. Rau uncoated txias- dov ca cov khoom, tus ntoo khaub lig-sectional cheeb tsam yog txo los ntawm tsis pub tsawg tshaj 25% thaum lub caij txias - dov txheej txheem; Txawm li cas los xij, rau cov khoom lag luam tiaj tus nrog qhov dav tsawg dua 600 mm- nrog rau qee yam tshwj xeeb- qib steels- cov khoom uas muaj tus ntoo khaub lig- ntu ntu txo qis dua 25% kuj tuaj yeem suav nrog hauv pawg no.
Raws li cov khoom siv, txias-cov khoom dov tuaj yeem muab faib ua cov ntawv txias-rolled steel, txias-rolled stainless hlau los xij, thiab txias-rolled aluminium ntawv. Muab faib los ntawm cov tuab, lawv tau muab faib ua cov ntawv nyias, cov ntawv nruab nrab, lossis cov ntawv tuab; tshwj xeeb, cov ntawv txias-cov ntawv nyias nyias muaj qhov tuab tsawg dua 3 hli, thaum txias-cov ntawv tuab tuab muaj qhov tuab ntawm 3 hli lossis ntau dua (nrog rau cov hlau hluav taws xob). Raws li cov txheej txheem kho saum npoo, lawv tuaj yeem raug cais ntxiv rau hauv xeb-cov ntaub ntawv tiv taus, cov ntawv coated (xws li, galvanized, xim-coated, thiab lwm yam), cov nplooj ntawv passivated, thiab lwm yam.
Nyob rau hauv cov nqe lus ntawm cov khoom daim ntawv, txias- dov nyias thiab tuab nplooj ntawv yog tsim nrog dawb- nthuav npoo thiab muab nyob rau hauv ib daim ntawv tiaj tus, nrog ib tug dav ntawm tsis tsawg tshaj li 600 mm. Txias-rolled steel strips raug xa mus rau hauv daim ntawv coil thiab muab faib ntxiv rau hauv txias- dov dav strips (nominal dav tsis tsawg dua 600 mm), slit txias-rolled wide strips (dov dav tsis pub tsawg tshaj 600 mm, tab sis nrog ib tug nominal dav ntawm tsawg tshaj li 600 mm), thiab tom qab nominal dav ntawm tsawg tshaj li 600 hli trimmed strip (nominal dav ntawm tsawg dua 600 mm).
