H-zoo li tus hlau yog siv nyob rau hauv txhua hom hlau qauv. Los ntawm cov ntawv thov me me xws li cov tsheb thauj mus rau cov ntawv loj xws li cov tsev siab siab, qhov dav-flange tsim thiab welded tsim muab H-beams qhov tsis sib xws ntawm lub zog-rau-qhov hnyav.
Cov flanges ntawm H-section yog ze li qhov dav ntawm qhov siab ntawm lub vev xaib, muab cov nqaj yuav luag square cross-section. Qhov no ua rau thaj tsam ntawm qhov chaw, ua rau cov nqaj tiv taus ntau dua rau buckling, uas yog vim li cas nws feem ntau yog siv vertically ua kem hauv cov qauv hlau.
