H-fibre ya fiberglass yamashanyarazi nubukungu bwambukiranya imipaka hamwe nubushakashatsi buhanitse hamwe nuburyo bwiza bwogukwirakwiza igice cyagabanijwe hamwe nimbaraga zifatika-zingana.Yiswe izina kuko igice cyacyo kinyuranye ninyuguti yicyongereza "H".Kubera ko ibice byose bigize urumuri rwa fiberglass ya H bitondekanye kuruhande rwiburyo, urumuri rwa fibre ya H rufite ibyiza byo kwihanganira kunama mu mpande zose, kubaka byoroshye, kuzigama ibiciro hamwe nuburemere bwubaka, kandi byarakoreshejwe cyane.
Umwirondoro wubukungu wambukiranya imiterere ufite ibice byambukiranya bisa n’inyuguti nkuru y’ikilatini H, nanone bita fiberglass beam beam, impande nini (inkombe) I-beam cyangwa parallel flange I-beam.Igice cyambukiranya urumuri rwa fiberglass ya H isanzwe ikubiyemo ibice bibiri: urubuga na plaque plaque, bizwi kandi nk'ikibuno n'impande.
Impande zimbere ninyuma ya flanges ya H-fiberglass beam irasa cyangwa yegeranye, kandi impera ya flange iri kumurongo ugororotse, niyo mpamvu izina parallel flange I-beam.Uburebure bwurubuga rwa H-fiberglass beam ni ntoya kurenza iyisanzwe I-beam ifite uburebure bumwe bwurubuga, kandi ubugari bwa flange nini kuruta ubw'ibisanzwe I-beam bifite uburebure bumwe bwurubuga, bityo nanone byitwa ubugari- inkombe I-beam.Kugenwa nuburyo bwayo, igice modulus, umwanya wa inertia nimbaraga zijyanye nimbaraga za H-fiberglass beam nibyiza cyane kurenza I-beam isanzwe yuburemere bumwe.
