Muaj ntau hom steel qhov rooj, tau ua nrog ib qho ntawm peb hom hlau; Galvanized, galvannealed, lossis txias dov.
Ntawm no yog qhov sib txawv:
Galvanized steel:Nyob rau hauv cov txheej txheem no, carbon hlau yog coated nrog ib txheej ntawm tag nrho zinc alloy, uas muaj zoo xeb tiv thaiv.
Galvannealed steel:Qhov no muaj cov hlau-zinc alloy thov hauv cov txheej txheem kub-dip. Nws yooj yim los pleev xim cov qhov rooj txij li lawv muaj lub matte tiav.
Txias Rolled Steel:Cov txheej txheem zeb siv rau cov hlau txias ua rau nws muaj zog dua tab sis nws yog qhov zoo dua rau cov qhov rooj steel sab hauv.
Kuj tseem muaj cov qhov rooj steel tawg, uas siv ob txheej ntawm cov hlau sib cais los ntawm rwb thaiv tsev los ntawm kev ua haujlwm thermal, ua kom koj lub tsev ntawm lub xyoo zoo nkauj-puag ncig.
Yog tias koj xav paub ntau ntxiv txog peb cov hluav taws kub lub qhov rooj hluav taws kub qhov rooj thiab cov qhov rooj ntawm AlibabaSx.en.Aspjfz.en.Arberyloferliist.0.4d611f5deodayq
