, ʻO ka flange oH Kuu kilaua like a kokoke like paha ma loko a ma waho, a ʻo ka hopena o ka flange ma ka ʻaoʻao ʻākau, no laila ua kapa ʻia ʻo ia ka flange I-steel. ʻOi aku ka mānoanoa o ka pūnaewele o ke kila H-like ma mua o ka I-beam maʻamau me ke kiʻekiʻe like o ka pūnaewele, a ʻoi aku ka laulā o ka flange ma mua o nā I-beam maʻamau me ke kiʻekiʻe like o ka pūnaewele, no laila ua kapa ʻia ʻo ia ʻo wide-rim I-beams. Hoʻoholo ʻia e ke ʻano, ʻoi aku ka maikaʻi o ka modulus pauku, ka manawa o ka inertia a me ka ikaika like o ka H-beam ma mua o ka I-beam maʻamau me ke kaumaha hoʻokahi. Hoʻohana ʻia i nā koi like ʻole o ka hoʻolālā metala, inā paha ma lalo o ke kuʻekuʻe ʻana o ka torque, ka ukana kaomi, ka ukana eccentric e hōʻike ana i kāna hana ʻoi aku ka maikaʻi, hiki ke hoʻomaikaʻi maikaʻi i ka hiki ke hoʻokō ma mua o ka I-steel maʻamau, e mālama ana i ka metala 10% ~ 40%. ʻO ke kila H-like he flange ākea, pūnaewele lahilahi, nā kikoʻī he nui, a me ka hoʻohana maʻalahi, hiki ke mālama i ka 15% a 20% o ka metala ma nā ʻano hana truss. No ka mea ua like kona flange i loko a me waho, a aia ka ʻaoʻao ma kahi kihi ʻākau, maʻalahi ka hui ʻana a hoʻohui i nā ʻāpana like ʻole, hiki ke mālama i kahi 25% o ka hana kuʻi ʻana a me ka riveting, a hiki ke hoʻolōʻihi i ka wikiwiki o ke kūkulu ʻana o ka papahana a pōkole ka manawa hana.
