MS Flat Bar / Carbon Steel Flat Bar / Kub Rolled Steel Flat Bar
1. Cov khoom tshwj xeeb tshwj xeeb.Lub thickness yog 8 ~ 50mm, qhov dav yog 150-625mm, qhov ntev yog 5-15m, thiab cov khoom specifications yog denser, uas yuav ua tau raws li cov kev xav tau ntawm cov neeg siv.Nws tuaj yeem siv ncaj qha los ntawm nruab nrab phaj tsis muaj kev txiav thiab tuaj yeem txuas ncaj qha.
2. Qhov saum npoo ntawm cov khoom yog du.Cov txheej txheem dej siab descaling yog siv ob zaug hauv cov txheej txheem los xyuas kom meej cov hlau nto du thiab huv.
3. Ob sab yog ntsug, thiab cov rhomboids yog qhov tseeb.Ob txoj hlua ntsug hauv kev ua tiav dov kom ntseeg tau zoo verticality ntawm ob sab, cov ces kaum meej, thiab zoo nto zoo ntawm ob sab.
4. Qhov loj ntawm cov khoom yog qhov tseeb, peb lub ntsiab lus sib txawv, tib theem sib txawv yog zoo dua li cov qauv steel phaj;cov khoom yog ncaj thiab cov duab zoo.Kev ua tiav dov txais cov txheej txheem dov tas li thiab tsis siv neeg looper tsis siv neeg tswj kom ntseeg tau tias tsis muaj steel piled thiab tsis muaj hlau yog rub.Cov khoom muaj qhov siab qhov tseeb.Qhov kev ua siab ntev, peb qhov sib txawv, tib lub strip sib txawv, kab mob khoov, thiab lwm yam tsis zoo dua li cov phaj nruab nrab.Zoo degree.Txias-shear txiav, siab precision nyob rau hauv ntev sizing.
5. Cov khoom siv ntawm cov khoom siv lub teb chaws tus qauv, uas yog tib yam li cov hlau phaj.Cov qauv kev ua tau zoo thiab cov qauv tsim tau raug teeb tsa raws li YB / T4212-2010 tus qauv (Q345B / Q235B xa mus rau GB / T1591-94 thiab GB / T700-06 qauv, raws li)
