CARBON STEEL H BEAM Q355B HM muaj npe vim nws cov duab. Cov kab sib txuas yog hu ua flanges, uas yog dav dua I-nqaj - li no lub npe dav flange beam - thiab cov kab kos nrog daim ntawv hu ua lub vev xaib. Dav dav flange beam tseem hu ua H-beam vim lawv cov duab sib txawv, zoo ib yam li tsab ntawv "H" thaum saib ntawm ntu ntu. Cov duab no muaj txiaj ntsig zoo rau kev nqa cov khoom hnyav yam tsis muaj kev khoov.
