Phindu la fiberglass yooneka ngati H ndi gawo lazachuma komanso mbiri yabwino kwambiri yokhala ndi gawo logawidwa bwino kwambiri komanso kuchuluka kwamphamvu kwa kulemera.Amatchulidwa chifukwa chodutsana ndi chilembo cha Chingerezi "H".Popeza mbali zonse za mtengo wa fiberglass wooneka ngati H zimakonzedwa molunjika, mtengo wa fiberglass wooneka ngati H uli ndi ubwino wokhotakhota molimba kumbali zonse, kumanga kosavuta, kupulumutsa mtengo ndi kulemera kwapangidwe, ndipo kwagwiritsidwa ntchito kwambiri.
Mbiri yazachuma yokhala ndi mawonekedwe ophatikizika ofanana ndi chilembo chachikulu cha Chilatini H, chomwe chimatchedwanso kuti mtengo wa fiberglass universal fiberglass beam, m'mphepete mwake (m'mphepete) I-beam kapena parallel flange I-beam.Gawo la mtanda la mtengo wa fiberglass wooneka ngati H nthawi zambiri limaphatikizapo magawo awiri: ukonde ndi mbale ya flange, yomwe imadziwikanso kuti chiuno ndi m'mphepete.
Mbali zamkati ndi zakunja za flanges za mtengo wa fiberglass wooneka ngati H zimafanana kapena kuyandikira kufananiza, ndipo malekezero a flange ali pakona yakumanja, chifukwa chake dzina lofananira flange I-beam.Makulidwe a ukonde wa fiberglass yooneka ngati H ndi yaying'ono kuposa ma I-mitanda wamba okhala ndi ukonde womwewo kutalika, ndipo m'lifupi mwake ndi yayikulu kuposa ya matabwa wamba omwe ali ndi ukonde womwewo, chifukwa chake amatchedwanso wide- m'mphepete I-mtengo.Kutengera mawonekedwe ake, gawo modulus, mphindi ya inertia ndi mphamvu yofananira ya H-woboola pakati fiberglass mtanda ndi bwino kwambiri kuposa wamba I-mitengo yolemera unit.
