S235JRH cov yeeb nkab steel yog hom kev tsim qauv hollow rau ntawm cov khoom siv hlau, ' Kev Cuam Tshuam cov zog ntawm chav tsev kub thiab khoom xa tuaj (kub dov).
Cov qib kawm no muaj npe rau nws cov kev tsim txiaj zoo heev thiab kev ua kom zoo, ua rau nws siv ntau yam thiab siv tau cov khoom siv hauv ntau yam kev tsim kho thiab kev tsim khoom lag luam. Tus Steel cov tshuaj lom neeg muaj pes tsawg leeg yog ua tib zoo tswj, nrog txwv cov pa roj carbon, phosphorus, thiab leej faj, uas txhawb rau nws txoj kev txhim khu kev ua haujlwm thiab yooj yim ntawm cov fabrication.
S235JRH hlau kav hlau yog tsim raws li ob puag ncig (CHS- duab lossis duab plaub}} duab plaub hau hollow. Qhov txheej txheem txheej txheem no muaj ib qho tshwj xeeb muaj zog - - Qhov muaj peev xwm muaj peev xwm thaum txo qhov hnyav tag nrho ntawm tus qauv.
** Cov ntawv thov tseem ceeb muaj: **
* ** kev tsim kho: ** Siv dav nyob rau hauv lub moj khaum rau cov tuam tsev, chav tsev muaj kev lag luam, chaw khaws ntaub ntawv, thiab chaw lag luam.
* ** Kev tsim qauv kev lag luam: ** Zoo tagnrho rau trusses, qhov chaw thav duab, txuas hniav, thiab lwm yam thauj khoom - cov kabmob qauv.
* ** NTXHIGE thiab cog engineering: ** Ua haujlwm hauv kev tsim kho cov cuab yeej siv cov khoom siv.
* ** Kev xaiv dav dav: ** Ib qho kev xaiv nrov rau tes ua, kev thaiv kev nyab xeeb, thiab ntau yam kev kos duab zoo thiab yooj yim ntawm kev teeb tsa.
Hauv cov ntsiab lus, S235JRH cov yeeb nkab steel yog qhov tseem ceeb thiab tus nqi-}} kev ua haujlwm zoo ntawm kev lag luam niaj hnub. Nws cov kev sib txuas ntawm kev lav lub zog, thiab kev ua tau zoo tshaj plaws ua rau nws xaiv qhov kev xaiv zoo rau cov kws ua haujlwm thiab cov ntaub thaiv cov khoom siv dav hlau.
