Trosolwg o Beam H wedi'i rolio'n boeth a Beam I
Trawst dur wedi'i rolio'n boeth gyda chroestoriad siâp H, a ddefnyddir yn bennaf mewn pentyrrau a strwythurau cynnal. Mae trawst-H wedi'i ddatblygu a'i optimeiddio o drawst-I, math o ddur proffil economaidd gyda galluoedd mecanyddol gwell. Mae'r platiau gwe a'r fflansau mewn plwm. Mae'r fflans fewnol yn rhedeg yn gyfochrog â'r un allanol. Mae ei fflansau'n syth iawn ac mae'r ymylon yn glir, wedi'u henwi'n arbennig oherwydd y tebygrwydd rhwng siâp yr adran a'r llythyren "H".
Defnyddir trawstiau-I dur ar gyfer amrywiaeth o gymwysiadau strwythurol. Defnyddir terminoleg benodol i ddisgrifio nodweddion a phriodweddau trawstiau-I.
Gellir dod o hyd i drawstiau-I dur ym mron pob prosiect adeiladu, o adeiladau uchel a phriffyrdd i adeiladu preswyl a chraeniau diwydiannol. Mae priodweddau'r trawst-I yn ei wneud yn ddewis gorau posibl i gydbwyso cryfder a phwysau trawst. Mae'r rhan fwyaf o arwynebedd trawsdoriadol trawst-I wedi'i leoli i ffwrdd o echel niwtral y trawst, gan arwain at foment inertia uchel, neu werth "I".
