Mokhoa oa Tlhahiso ea Sehlahisoa
Ts'ebetso ea tlhahiso bakeng sa mahlakore a tloaelehileng a H hangata e kenyelletsa mehato ea bohlokoa e latelang:
Tokisetso ea Thepa e Tala: Thepa e tala bakeng sa mahlakore a H hangata ke li-billet tsa tšepe. Li-billet tsena lia hloekisoa le ho futhumatsoa ho itokisetsa ts'ebetso le ho etsoa hamorao.
Ho Rolla ka Mocheso: Li-billet tse seng li chesitsoe li fepeloa ka har'a leloala le chesang. Leloaleng le chesang le rolang, li-billet li phuthoa ka har'a li-roller tse ngata, butle-butle li etsa sebopeho sa H-beam se nang le karolo e tšekaletseng.
Ho Sebetsa ka Moqomo (Ha ho hlokahale): Maemong a mang, ho ntlafatsa ho nepahala le boleng ba bokaholimo ba H-beam, H-beams tse phutholohileng ka mocheso le tsona li ka 'na tsa sebetsa ka mokhoa o batang, joalo ka ho phutholla le ho hula ka mokhoa o batang.
Ho Seha le ho Qetela: Kamora ho phutholla le ho sebetsa ka serame, mahlakore a H aa sehoa le ho phethoa ho fihlela litekanyo le bolelele bo itseng joalo ka ha moreki a hloka.
Kalafo ea Bokaholimo: Li-H-beam lia hloekisoa le ho phekoloa ka thibelo ea mafome ho netefatsa boleng ba bokaholimo le ho hanyetsa mafome.
Tlhahlobo le Sephutheloana: Li-H-beam tse felileng li hlahlojoa boleng, ho kenyeletsoa le tlhahlobo ea ponahalo, ho nepahala ha litekanyo le thepa ea mechini. Hang ha li tšoaneleha, lia pakoa le ho romelloa ho moreki.
