Hla-ntu ntu: kwv yees 11.7 square ntiv tes.
Cov Khoom Siv: A36 Hlau, Ib Cov Hlau Txheej Txheem Cov Hlau, muaj ib qho txiaj ntsig muaj zog ntawm kwv yees li 250mpa (lossis 36ksi).
W12X45 h Sect Hlau Beam
Qhov loj me (nti): kuj nominal qhov tob ntawm 12 ntiv tes, tab sis qhov hnyav nce mus rau 45 phaus ib txhais ko taw.
Hla Cheeb Tsam Ntu: Loj dua W12X40 hect Hlau, kwv yees li ntawm 13.3 square ntiv tes.
Cov Khoom Siv: A36 Hlau, Ib Cov Hlau Txheej Txheem Cov Hlau, muaj ib qho txiaj ntsig muaj zog ntawm kwv yees li 250mpa (lossis 36ksi).
Cov yam ntxwv ntawm W12X40 W12X45 H-Profile Hlau
Cov Khoom Siv Neeg Kho Tshuab:A36 Hlau muaj ib qho txiaj ntsig lub zog ntawm txog 250MPA (lossis 36ksi) thiab zoo tensile lub zog, thiab siv nyob rau hauv dav hlau qauv, suav nrog cov thav ntawv, txhawb nqa, thiab lwm yam.
Tshuaj lom neeg cov tshuaj:Nws yog mas muaj xws li hlau, thiab muaj cov pa roj carbon ntau (siab kawg} 0}}. 26%), thiab lwm yam kab kawm xws li phosphorus thiab leej faj. Cov kev sib tw ntawm cov ntsiab no tau tswj hwm kom ntseeg tau cov khoom siv tshuab ntawm cov hlau.
Kev Ua Tau Zoo:A36 Hlau Beam H Yooj yim los txiav, Weld thiab daim ntawv, thiab yog qhov tsim nyog rau kev tsim cov phiaj xwm thiab kev hloov kho.
Chaw Thov:Vim tias qhov kev ua tau zoo thiab kev lag luam W12X0 H Profile thiab Wrector hlau feem ntau siv nyob rau hauv cov tsev nyob, cov vaj tse lag luam thiab lwm yam phiaj xwm kev lag luam.
