ʻO ke kaola fiberglass ʻano H kahi ʻāpana keʻa waiwai a me kahi ʻano hana kiʻekiʻe me ka hoʻolaha ʻana o ka ʻāpana keʻa i ʻoi aku ka maikaʻi a me ka lakio ikaika-i-kaumaha kūpono. Ua kapa ʻia ʻo ia no ka mea ua like kona ʻāpana keʻa me ka leka Pelekane "H". ʻOiai ua hoʻonohonoho ʻia nā ʻāpana āpau o ke kaola fiberglass ʻano H ma nā kihi ʻākau, loaʻa i ke kaola fiberglass ʻano H nā pono o ke kūlou ikaika i nā ʻaoʻao āpau, ke kūkulu maʻalahi, ka mālama kālā a me ke kaumaha kūkulu māmā, a ua hoʻohana nui ʻia.
ʻO kahi ʻāpana ʻāpana kūʻai waiwai me ke ʻano ʻāpana like me ka leka Latin nui H, i kapa ʻia hoʻi he beam fiberglass universal, wide edge (edge) I-beam a i ʻole parallel flange I-beam. ʻO ka ʻāpana ʻāpana o ka beam fiberglass ʻano H e komo pinepine i ʻelua ʻāpana: ka pūnaewele a me ka flange plate, i ʻike ʻia hoʻi ʻo ka pūhaka a me ka lihi.
ʻO nā ʻaoʻao o loko a me waho o nā flanges o ke kaola fiberglass ʻano H he like a kokoke paha i ke ʻano like, a aia nā wēlau flange ma nā kihi ʻākau, no laila ka inoa ʻo ke kaola I-flange like. ʻOi aku ka liʻiliʻi o ka mānoanoa o ka pūnaewele o ke kaola fiberglass ʻano H ma mua o nā kaola I maʻamau me ke kiʻekiʻe pūnaewele like, a ʻoi aku ka nui o ka laulā o ka flange ma mua o nā kaola I maʻamau me ke kiʻekiʻe pūnaewele like, no laila ua kapa ʻia hoʻi ʻo ia he kaola I-ʻaoʻao ākea. Hoʻoholo ʻia e kona ʻano, ʻoi aku ka maikaʻi o ka modulus ʻāpana, ka manawa o ka inertia a me ka ikaika e pili ana o ke kaola fiberglass ʻano H ma mua o nā kaola I maʻamau o ke kaumaha like.
