Cov phaj hlau tau muab faib ua ob hom: daim hlau nyias thiab daim hlau tuab. Nyias steel phaj <4 hli (thinnest 02 hli), tuab steel phaj 4 ~ 60 hli, ntxiv tuab steel phaj 60 ~ 115 hli.
Cov ntawv hlau tau muab faib ua kub-kuav los tiag thiab txias-dov raws li dov.
Cov phaj nyias nyias yog cov phaj hlau nrog lub thickness ntawm 0.2-4mm uas ua los ntawm kub dov los yog txias dov. Qhov dav ntawm nyias steel phaj yog nyob nruab nrab ntawm 500-1800mm. Ntxiv nrog rau kev xa khoom ncaj qha tom qab dov, cov ntawv nyias nyias kuj tseem khaws cia, galvanized thiab tinned. Raws li kev siv sib txawv, cov phaj nyias nyias yog dov los ntawm cov khoom siv sib txawv thiab qhov dav ntawm cov phaj nyias yog 500 ~ 1500 hli; qhov dav ntawm daim ntawv tuab yog 600 ~ 3000 hli. Cov nplooj ntawv raug cais raws li cov hlau, suav nrog cov hlau zoo tib yam, cov hlau zoo, cov hlau alloy, lub caij nplooj ntoo hlav, cov hlau tsis muaj steel, cov cuab yeej hlau, cov hlau tsis muaj cua sov, cov kabmob steel, silicon steel thiab cov ntawv hlau ntshiab, thiab lwm yam.; Raws li kev siv, muaj roj nruas phaj, Enamel phaj, mos txwv phaj, thiab lwm yam .; Raws li cov txheej txheem saum npoo, muaj galvanized ntawv, tin-plated ntawv, txhuas-plated ntawv, yas puas steel phaj, thiab lwm yam.
Thick steel phaj yog ib lo lus dav dav rau cov hlau phaj nrog lub thickness ntawm ntau tshaj 4 hli. Nyob rau hauv kev ua hauj lwm, steel daim hlau nrog ib tug tuab ntawm tsawg tshaj li 20 hli feem ntau hu ua nruab nrab daim hlau, steel daim hlau nrog ib tug tuab ntawm > 20mm mus rau 60mm yog hu ua tuab daim hlau, thiab steel phaj nrog ib tug thickness ntawm > 60mm yuav tsum tau dov rau. tshwj xeeb hnyav phaj zeb, yog li nws yog hu ua ntxiv hnyav phaj. Qhov dav ntawm tuab steel phaj yog los ntawm 1800mm-4000mm. Cov phaj tuab yog muab faib ua shipbuilding steel daim hlau, choj hlau daim hlau, boiler steel daim hlau, siab siab nkoj steel daim hlau, checkered steel daim hlau, tsheb hlau daim hlau, armored steel daim hlau thiab puas steel phaj raws li lawv siv. Cov qib steel ntawm tuab steel phaj feem ntau yog tib yam li cov hlau phaj nyias. Nyob rau hauv cov nqe lus ntawm cov khoom, nyob rau hauv tas li ntawd mus rau lub choj steel daim hlau, boiler steel daim hlau, tsheb manufacturing steel daim hlau, siab hlab ntsha steel daim hlau thiab multi-layer high-pressure nkoj steel daim hlau, uas yog ntshiab tuab daim hlau, ib co ntau yam ntawm steel daim hlau xws li tsheb. girder steel daim hlau (25 ~ 10 hli tuab), qauv hlau daim hlau, thiab lwm yam. steel daim hlau (2.5-8 hli tuab), stainless hlau daim hlau, cov hlau tsis kub-resistant steel phaj thiab lwm yam yog sib tshuam nrog nyias daim hlau.
