H seem hlau tau muab faib ua cov kub kuav los tiag H seem hlau thiab welded H seem hlau (H).
Qhov kub dov H seem steel tau muab faib ua peb hom: dav flange H seem hlau (HM) thiab nqaim flange H seem hlau (HN) hauv nruab nrab flange.
HW yog H ntu steel qhov siab thiab dav flange yog qhov sib luag; Mas siv hauv reinforced qhob ncej kem steel tub ntxhais kem, Tseem hu ua txhav steel kem; Hlau qauv feem ntau yog siv rau kem HM H seem steel qhov siab thiab flange dav piv yog li 1.33 ~ ~ 1.75 feem ntau hauv cov qauv hlau: steel ncej sab siv tau ua ncej nqaj hauv cov qauv ncej hauv qab ua haujlwm dynamic;
Lub HN ntawm cov cuab yeej siv platform yog H steel qhov siab thiab Qhov seem ntawm qhov flange dav dav ntau dua los yog sib npaug rau 2, uas yog siv cov nqaj hlau; kev siv ntawm I-nqaj yog sib npaug rau HN ntu steel; cov khoom siv tseem ceeb ntawm H seem steel yog Q235B 、 SM490 、 SS400 、 Q345 、 Q345B thiab hais txog.
