ʻO ke kaola H he ʻano kila lōʻihi me ka ʻāpana keʻa H-ʻano, i kapa ʻia no ka mea ua like kona ʻano kūkulu me ka leka Pelekane "H". He ikaika kiʻekiʻe kona a me nā waiwai mechanical maikaʻi, a hoʻohana nui ʻia i ke kūkulu ʻana, ke alahaka, ka hana mīkini a me nā ʻoihana ʻē aʻe.
Kūlana Lahui Kina (GB)
ʻO ka hapa nui o nā kukuna H ma Kina e hana ʻia a hoʻokaʻawale ʻia ma muli o nā kukuna H i ʻōwili wela ʻia a me nā kukuna T ʻāpana (GB/T 11263-2017). Ma muli o ka laulā o ka flange, hiki ke hoʻokaʻawale ʻia i loko o ka kukuna H flange ākea (HW), ka kukuna H flange waena (HM) a me ka kukuna H flange naiki (HN). No ka laʻana, hōʻike ʻo HW100 × 100 i ka kukuna H flange ākea me ka laulā o ka flange o 100mm a me ke kiʻekiʻe o 100mm; hōʻike ʻo HM200 × 150 i ka kukuna H flange waena me ka laulā o ka flange o 200mm a me ke kiʻekiʻe o 150mm. Eia kekahi, aia nā kila lahilahi i hana anu ʻia a me nā ʻano kukuna H kūikawā ʻē aʻe.
Nā Kūlana ʻEulopa (EN)
Ma muli o nā kūlana ʻEulopa, ua hahai nā kukuna H ma ʻEulopa i kekahi mau kūlana ʻEulopa, e like me EN 10034 a me EN 10025, e hōʻike ana i nā kikoʻī dimensional, nā koi mea, nā waiwai mechanical, ka maikaʻi o ka ʻili a me nā lula nānā no nā kukuna H. ʻO nā kukuna H maʻamau ʻEulopa e komo pū me ka moʻo HEA, HEB a me HEM; hoʻohana pinepine ʻia ka moʻo HEA e kū i nā ikaika axial a me vertical, e like me nā hale kiʻekiʻe; kūpono ka moʻo HEB no nā hale liʻiliʻi a waena; a kūpono ka moʻo HEM i nā noi e pono ai kahi hoʻolālā māmā ma muli o kona kiʻekiʻe a me ke kaumaha liʻiliʻi. Loaʻa kēlā me kēia moʻo i nā nui like ʻole.
Nā moʻo HEA: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, a pēlā aku.
Moʻo HEB: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, a pēlā aku.

ʻO ke kukuna H maʻamau ʻAmelika(ASTM/AISC)
Ua hoʻomohala ka American Society for Testing and Materials (ASTM) i nā kūlana kikoʻī no nā kukuna H, e like me ASTM A6/A6M. Hōʻike pinepine ʻia nā hiʻohiʻona kukuna H American Standard ma ke ʻano Wx a i ʻole WXxxy, e laʻa, W8 x 24, kahi e pili ana ka "8" i ka laulā o ka flange ma nā ʻīniha a ʻo "24" ke kaumaha no kēlā me kēia kapuaʻi o ka lōʻihi (paona). Eia kekahi, aia ʻo W8 x 18, W10 x 33, W12 x 50, a pēlā aku. Nā māka ikaika maʻamau ahouASTM A36, A572, a pēlā aku.
Kūlana Pelekane (BS)
Ma lalo o ke Kūlana Pelekane, ua hahai nā kukuna H i nā kikoʻī e like me BS 4-1:2005+A2:2013. ʻO nā ʻano e komo pū ana me HEA, HEB, HEM, HN a me nā mea ʻē aʻe he nui, me ka moʻo HN e kau ana i ka manaʻo nui i ka hiki ke kū i nā ikaika ākea a me ke kū. Ma hope o kēlā me kēia helu kumu hoʻohālike, aia kahi helu e hōʻike i nā palena nui kikoʻī, e laʻa, hōʻike ʻo HN200 x 100 i kahi kumu hoʻohālike me ke kiʻekiʻe a me ka laulā kikoʻī.
Kūlana ʻOihana Kepanī (JIS)
ʻO ke Kūlana ʻOihana Kepanī (JIS) no nā kukuna H e pili nui ana i ke kūlana JIS G 3192, nona kekahi mau papa e like meSS400, SM490, a pēlā aku. He kila kūkulu maʻamau ʻo SS400 i kūpono no nā hana kūkulu maʻamau, ʻoiai ʻo SM490 e hāʻawi i ka ikaika tensile kiʻekiʻe a kūpono hoʻi no nā noi hana kaumaha. Hōʻike ʻia nā ʻano ma ke ʻano like me Kina, e laʻa me H200 × 200, H300 × 300, a pēlā aku. Hōʻike ʻia nā ana e like me ke kiʻekiʻe a me ka laulā o ka flange.
Nā Kūlana ʻOihana Kelemania (DIN)
Hoʻokumu ʻia ka hana ʻana o nā kukuna H ma Kelemania ma nā kūlana e like me DIN 1025, no ka laʻana ka moʻo IPBL. Hōʻoia kēia mau kūlana i ka maikaʻi a me ke kūlike o nā huahana a kūpono no nā ʻano hana ʻoihana like ʻole.

Nā Kūlana: AS/NZS 1594 etc.
Nā Kumu Hoʻohālike: e.g. 100UC14.8, 150UB14, 150UB18, 150UC23.4, a pēlā aku.
I ka hōʻuluʻulu manaʻo, ʻoiai ke ʻokoʻa nā kūlana a me nā ʻano o nā H-beams mai kēlā ʻāina a kēia ʻāina a me kēlā ʻāina a kēia ʻāina, kaʻana like lākou i ka pahuhopu like o ka hōʻoia ʻana i ka maikaʻi o ka huahana a me ka hoʻokō ʻana i nā pono ʻenekinia like ʻole. I ka hana maoli, i ke koho ʻana i ka H-beam kūpono, pono e noʻonoʻo i nā koi kikoʻī o ka papahana, nā kūlana o ke kaiapuni a me nā palena kālā, a me ka hoʻokō ʻana i nā code hale kūloko a me nā kūlana. Hiki ke hoʻonui pono ʻia ka palekana, ka lōʻihi a me ka hoʻokele waiwai o nā hale ma o ke koho kūpono a me ka hoʻohana ʻana i nā H-beams.
