I-fiberglass emise okwe-H iyi-cross-section eyongayo kanye nephrofayili esebenza kahle kakhulu enokusabalalisa okuthuthukisiwe kwezingxenye eziphambanayo kanye nesilinganiso esizwakalayo samandla nesisindo. Iqanjwe ngoba ingxenye yayo ephambanayo iyafana nohlamvu lwesiNgisi oluthi "H". Njengoba zonke izingxenye ze-fiberglass beam emise okwe-H zihlelwe ngama-engeli alungile, i-fiberglass emise okwe-H inenzuzo yokumelana nokugoba okuqinile kuzo zonke izinhlangothi, ukwakhiwa okulula, ukonga izindleko kanye nesisindo esilula sesakhiwo, futhi isetshenziswe kabanzi.
Iphrofayili yesigaba esiphambanayo esongayo enomumo wesigaba esiphambanayo ofana nosonhlamvukazi wesiLatini u-H, obizwa nangokuthi i-universal fiberglass beam beam, unqenqema olubanzi (umphetho) we-I-beam noma i-parallel flange I-beam. Ingxenye yesiphambano se-fiberglass emise okwe-H ngokuvamile ihlanganisa izingxenye ezimbili: ipuleti lewebhu ne-flange, eyaziwa nangokuthi ukhalo nonqenqema.
Izinhlangothi zangaphakathi nezingaphandle zama-flanges ze-fiberglass beam emise okwe-H ziyahambisana noma zisondele ngokuhambisana, futhi iziphetho ze-flange ziku-engeli kwesokudla, yingakho igama elithi parallel flange I-beam. Ugqinsi lwewebhu logodo lwe-fiberglass olumise okwe-H luncane kunalolo lwe-I-imishayo evamile enobude obufanayo bewebhu, futhi ububanzi be-flange bukhulu kunobu-I-imishayo evamile enobude obufanayo bewebhu, ngakho bubizwa nangokuthi ububanzi- onqenqemeni I-beam. Inqunywa ngokuma kwayo, i-modulus yesigaba, umzuzu we-inertia namandla ahambisanayo we-fiberglass emise okwe-H ingcono kakhulu kune-I-imishayo evamile yeyunithi yesisindo esifanayo.
