H-zoo li tus hlau yog ib qho kev lag luam hla ntu thiab kev ua haujlwm siab nrog ntau qhov kev faib tawm ntawm cheeb tsam zoo dua thiab tsim nyog lub zog-rau-qhov hnyav. Nws yog lub npe vim hais tias nws qhov cross-section yog tib yam li tsab ntawv Askiv "H".
Txij li txhua qhov ntawm H-shaped steel yog teem rau ntawm txoj cai kaum, H-zoo li tus hlau muaj qhov zoo ntawm qhov muaj zog dabtsi yog khoov nyob rau hauv tag nrho cov lus qhia, kev tsim kho yooj yim, txuag nqi thiab lub teeb nyhav, thiab tau siv dav.
Ob sab npoo ntawm H-shaped steel tsis muaj txoj kab nqes ntawm sab hauv thiab ncaj. Qhov no ua rau cov vuam thiab splicing ntawm H-beams yooj yim dua rau kev khiav lag luam dua li I-beams, muaj cov cuab yeej zoo dua qub rau ib chav tsev qhov hnyav, thiab tuaj yeem txuag tau ntau cov ntaub ntawv thiab siv sijhawm.
Ntu I-beam tuaj yeem tiv taus qhov siab ncaj thiab tuaj yeem tiv taus qhov nro, tab sis qhov loj ntawm ntu ntu tsis tuaj yeem tiv taus torsion vim qhov nqaim phaj. H steel yog qhov sib txawv, ob leeg muaj lawv tus kheej zoo thiab qhov tsis zoo.
