1. Lub flange yog dav thiab lateral stiffness yog loj. Muaj zog dabtsi yog khoov tsis kam.
2. Ob qhov chaw ntawm flange yog sib npaug rau ib leeg, ua rau kev sib txuas, kev ua haujlwm thiab kev teeb tsa yooj yim.
3. Piv nrog welded I-beam, nws muaj tus nqi qis, siab precision thiab me me residual stress. Nws tsis xav tau cov khoom siv vuam kim thiab kev tshawb nrhiav vuam, txuag txog 30% ntawm tus nqi ntawm cov qauv steel ntau lawm.
4. Nyob rau hauv tib lub hla-sectional load. Kub dov H steel qauv yog 15% -20% sib dua li ib txwmsteel qauv.
5. Piv nrog rau cov qauv pob zeb, cov qauv kub-dov H steel tuaj yeem ua rau thaj tsam siv tau los ntawm 6%, thaum tus qauv tus kheej qhov hnyav yog txo los ntawm 20% mus rau 30%, txo qhov kev ntxhov siab sab hauv ntawm cov qauv tsim.
6. H-shaped steel tuaj yeem ua tiav rau hauv T-shaped steel, thiab honeycomb beams tuaj yeem ua ke los tsim ntau cov ntawv hla ntu, uas ua tau raws li qhov xav tau ntawm engineering tsim thiab ntau lawm.
