Izigaba ze-HEA ne-HEByizinsika ze-H ezibanzi ze-flange ezijwayelekile zaseYurophu.Izingxenye zomsebe we-HEAinezingcezu ezincane kanye nesisindo esiphansi, okwenza zifaneleke ezakhiweni zohlaka ezinemithwalo elula, njengezindlu zokuhlala kanye nezakhiwo zezentengiselwano ezijwayelekile. Ngokuphambene nalokho,Izingxenye zomsebe we-HEBzinezingqimba ezijiyile kanye nesisindo esikhulu, zinikeza amandla aphezulu okuthwala imithwalo yezicelo ezithwala imithwalo ephezulu njengezitshalo zezimboni namabhuloho. Lolu chungechunge luhlanganisa ne-HEM heavy-duty H-beams, enikeza amandla aphezulu okuthwala imithwalo.
Izindinganiso zokukhiqiza ziwela ezigabeni ezimbili: ubukhulu bezingxenye eziwela phansi buhambisana ne-EN 10034, kuyilapho amazinga ezinto ezisetshenziswayo ehambisana ne-EN 10025 (amabanga avamile afaka i-S235, i-S275, kanye ne-S355). Imininingwane ejwayelekile yesitoko yezingxenye ze-HEA kanye ne-HEB ihlanganisa ububanzi obuphelele kusukela ku-100 kuya ku-1000.
Uchungechunge lwe-HEA luyibanga elilula. Ama-flange amancane nama-web asho ukuthi kusetshenziswa insimbi encane ngemitha; ngenxa yalokho, i-HEA iyindlela ekhethwayo lapho imithwalo iphakathi nendawo futhi ukuzisindela kuyinto ebalulekile okufanele icatshangelwe (njengezinsika zaphansi, ama-purlin ophahleni, kanye nohlaka lwesibili ezakhiweni zezentengiselwano nezindawo zokuhlala). I-HEA 200 inesisindo esingu-42.3 kg/m.
Imishayo ye-HEB inezingqimba ezijiyile kanye nama-web, okuvumela ukuthi isekele imithwalo esindayo yokujula kwemishayo ethile. Yindlela ejwayelekile yokukhetha amakholomu ayinhloko kanye nemishayo emikhulu, kanye nezinhlelo zokusebenza ezidinga ukugoba okwandisiwe noma umthamo wokuthwala umthwalo we-axial ngaphandle kokwandisa ukujula kwemishayo. Imishayo ye-HEB 200 inesisindo esingu-61.3 kg/m2—cishe ngo-45% kune-HEA 200—kodwa inikeza i-section modulus ephakeme cishe ngo-40%.

S355J2iyizinga lensimbi elichazwe kabanzi kakhulu kumaphrojekthi ezimboni kanye nengqalasizinda.
Kumafreyimu okwakha ajwayelekile anezikhawu eziphakathi nendawo,S275JRngokuvamile kwanele futhi kushibhile kancane.
S235ifanele amalungu esibili, izibambo, kanye nozimele ezilayishwe kancane.
