Cov xim-ua xim steel phaj yog tsim los ntawm cov khaub thuas sib xyaw-txias steel sawb thiab galvanized steel (electro-galvanized thiab kub-dip galvanized) raws li cov txheej hauv nruas ntu. Tom qab cov qauv ua kom nto (degreasing thiab tshuaj kho mob), nws yog coated nrog txheej los ntawm cov xim txheej rau cov menyuam. Los yog ntau txheej kua ua kua pleev xim, uas tuaj yeem ci thiab txias.
Ntawm cov txuas ntxiv txuas, txias-kuav los tiag sawb hlau thiab galvanized sawb hlau (electro-galvanized thiab kub-dip galvanized) yog siv los ua cov khoom hloov pauv. Tom qab cov qauv ua kom nto (degreasing thiab tshuaj kho mob), ib lossis ntau txheej txheej ua kua yog thov los ntawm cov txheej ua cov roj. Txheej, phaj tom qab ci thiab txias yog cov xim lo ua ke. Txij li cov xim hlau tuaj yeem muaj ntau yam xim, nws yog qhov ib txwm hu rau cov ntawv coated steel ntawv xim coated steel ntawv. Thiab vim hais tias cov txheej txheej yog ua ntej ua ntej cov phaj steel tsim, nws yog hu ua pre-coated steel phaj txawv teb chaws.
Xim xim txheej steel phaj yog txheej organic thov rau saum npoo ntawm hlau. Nws muaj qhov zoo ntawm cov tsos zoo nkauj, qaim xim, lub zog siab, zoo corrosion tsis kam, thiab yooj yim ua thiab tsim. Nws tseem tso cai rau cov neeg siv txo nqi thiab txo kev ua qias tuaj.
Txij li thaum txoj kev tsim ua thawj txuas nruam cov xim steel phaj cov kab hauv Tebchaws Asmeskas xyoo 1935, cov xim-xim steel cov hlau tau siv dav. Tam sim no, muaj ntau ntau yam xim ntawm cov xim-txheej steel cov ntawv, txog ntau dua 600 hom, thiab cov xim-cov ntawv-xim muaj qhov zoo ntawm cov organic polymers thiab cov nplooj ntawv steel. Nws tsis tsuas yog muaj cov xim zoo, tsim kom zoo, tiv taus corrosion, thiab cov khoom tsim kho kom zoo nkauj ntawm cov organic polymers, tab sis kuj tseem muaj lub zog loj thiab kev ua cov hlau tsis yooj yim. Nws tuaj yeem yooj yim ua los ntawm stamping, txiav, khoov, thiab kos duab sib sib zog nqus. Qhov no ua rau cov khoom tsim los ntawm cov organic coated steel daim hlau muaj kev ua haujlwm zoo, kev ua kom zoo nkauj, kev tsim khoom thiab kav ntev.
