Kuv-beam: I-beam flange muaj qhov sib txawv ntawm qhov sib txawv uas yog tuab dua ntawm lub vev xaib thiab nyias nyias rau sab nraud;
H-zoo li tus hlau: Lub flange ntawm H-zoo li tus hlau yog sib npaug sib npaug. HW, HM, HN thiab H yog cov npe dav dav ntawm H-shaped steel. H-shaped steel yog welded;
HW: HW, HM, HN yog kub dov, HW yog qhov siab thiab flange dav yog qhov yooj yim sib npaug, feem ntau yog siv rau steel core txhua kab hauv cov pob zeb ua kom muaj zog, tseem hu ua cov kab hlau nruj, feem ntau yog siv rau txhua kab hauv cov qauv steel.
HM: HM yog qhov sib piv ntawm qhov siab thiab flange dav ntawm kwv yees li 1.33 ~ 1.75. Nws yog tsuas yog siv raws li steel ncej kab hauvsteel qauvthiab raws li thav duab kab teeb nyob rau hauv thav duab qauv uas dais dynamic loads, xws li khoom platforms;
HN:HN yog qhov sib piv ntawm qhov siab rau flange dav ntau dua lossis sib npaug rau 2. Nws yog siv rau cov kab teeb. Kev siv I-beam yog sib npaug rau HN seem steel.
