H-beams I-beam Kub Rolled Iron Carbon Steel Kub dip galvanized

H-section steel yog ib hom kev lag luam seem thiab kev ua haujlwm siab nrog ntau qhov kev faib tawm ntawm cheeb tsam thiab qhov tsim nyog lub zog-rau-qhov hnyav. Nws yog lub npe vim nws seem yog tib yam li tsab ntawv Askiv "H". Txij li ntau qhov chaw ntawm H-shaped steel yog teem rau ntawm lub kaum sab xis, H-shaped steel muaj qhov zoo ntawm kev khoov muaj zog, kev tsim kho yooj yim, kev txuag nqi thiab lub teeb qauv hnyav nyob rau hauv tag nrho cov lus qhia, thiab tau siv dav. Lub thickness ntawm lub vev xaib ntawm H-beam yog me dua li ntawm qhov zoo tib yam I-nqaj nrog tib qhov siab ntawm lub vev xaib, thiab qhov dav ntawm flange yog loj dua li ntawm qhov zoo tib yam I-beam nrog tib qhov siab ntawm lub vev xaib, yog li nws tseem hu ua dav-ntug I-beam. Kev txiav txim siab los ntawm cov duab, seem modulus, lub sij hawm ntawm inertia thiab coj lub zog ntawm H-beams yog qhov zoo dua li cov qauv I-beams ntawm tib qhov hnyav. Siv hauv cov qauv hlau nrog cov kev xav tau sib txawv, txawm hais tias nws dais lub sijhawm khoov, siab load, lossis eccentric load, nws qhia tau hais tias nws qhov kev ua tau zoo dua. Piv nrog rau I-nqaj zoo tib yam, nws tuaj yeem txhim kho lub peev xwm thauj khoom thiab txuag hlau los ntawm 10% -40%. H-zoo li tus hlau muaj flanges dav, nyias webs, ntau yam specifications, thiab saj zawg zog siv. Nws tuaj yeem txuag tau 15% txog 20% ​​ntawm cov hlau thaum siv ntau yam truss qauv. Vim hais tias cov flanges yog sib npaug rau sab hauv thiab sab nraud, thiab cov npoo yog nyob ntawm txoj cai kaum, nws yog ib qho yooj yim los sib sau ua ke thiab sib xyaw ua ke rau hauv ntau yam khoom, uas tuaj yeem txuag tau li ntawm 25% ntawm cov vuam thiab riveting workload, uas tuaj yeem ua kom nrawm nrawm ntawm kev tsim kho. project thiab shorten lub sij hawm tsim kho.
