Steel kauj, tseem hu ua steel kauj. Cov hlau yog dov los ntawm kub nias thiab txias nias. Txhawm rau kom yooj yim khaws cia thiab kev thauj mus los thiab kev ua ntau yam. Tsim coil feem ntau yog kub-dov coil thiab txias-dov coil. Kub dov kauj yog ib yam khoom ua ntej billet recrystallization. Cold dov kauj yog ua tom qab ntawm kub dov kauj. Peb lub Hoobkas tsuas yog tsim thiab ua haujlwm txias dov coil. Hlau kauj, xim coated coil thiab peb cov neeg siv khoom koom tes feem ntau xaj steel kauj nrog qhov hnyav li ntawm 25-27t. Tuam Tshoj qhov kub dov muaj peev xwm txuas ntxiv nthuav dav, twb muaj kaum ob ntawm cov kab kub dov ntau lawm, thiab qee qhov haujlwm tab tom yuav tsim los yog muab tso rau hauv kev ua haujlwm. Piv txwv li, peb muag dx51d Z100 galvanized steel kauj zoo.

Xim txheej yob yog ib yam khoom raws li kub-dip galvanized phaj, kub-dip aluminium zinc phaj thiab electro galvanized phaj. Tom qab cov txheej txheem degreasing (tshuaj degreasing thiab tshuaj hloov pauv tshuaj), ib lossis ntau txheej ntawm cov organic coatings yog coated rau ntawm qhov chaw, thiab tom qab ntawd ci thiab solidified. Nws yog lub npe hu ua cov xim hlau coated coated nrog ntau yam xim ntawm cov organic coatings, uas yog hu ua xim coated coil luv luv. Ntxiv nrog rau cov zinc txheej tiv thaiv, cov organic txheej ntawm zinc txheej plays lub luag haujlwm hauv kev npog thiab tiv thaiv cov xim coated steel sawb nrog kub-dip galvanized steel sawb ua cov khoom siv hauv paus, thiaj li tiv thaiv cov hlau sawb los ntawm xeb. Lub neej kev pab cuam yog kwv yees li 1.5 npaug ntev dua li ntawm galvanized steel sawb. Cov xim coated yob muaj lub teeb yuag, zoo nkauj tsos thiab zoo tiv thaiv corrosion, thiab tuaj yeem ua tiav ncaj qha. Cov xim feem ntau muab faib ua grey dawb, hiav txwv xiav thiab cib liab. Nws yog tsuas yog siv hauv kev lag luam tshaj tawm, kev tsim kho kev lag luam, kev lag luam hauv tsev, khoom siv hluav taws xob, kev lag luam rooj tog thiab kev lag luam tsheb thauj mus los.

Cov txheej uas siv rau hauv cov xim txheej yob yuav tsum xaiv cov khoom tsim nyog raws li qhov sib txawv siv ib puag ncig, xws li polyester silicon hloov polyester, polyvinyl chloride yas sol, polyvinylidene chloride, thiab lwm yam. Cov neeg siv tuaj yeem xaiv raws li lub hom phiaj.
