1.H txhais li cas hauv cov hlau?

high carbon stainless hlau

"H" qib yog qib siab carbon stainless hlau, muaj kev txhim kho lub zog ntawm qhov kub siab - feem ntau siab dua 500℃. Cov qib carbon siab no muaj siab luv-lub sij hawm thiab ntev- lub sij hawm creep zog. Lawv feem ntau yog tsim nyob rau hauv daim ntawv ntawm cov yeeb nkab thiab phaj.

 

2.Dab tsi ntawm cov hlau siv hauv H beams?

Steel h-Pile beams thiab steel wide flange beams tuaj nyob rau hauv yim ASTM qauv, xws li A36, A572-Qib 50, A588, A690, A709, A913-Qib 50, A913-Qib 65, thiab A992. ASTM A36 feem ntau siv rau cov khoom siv hlau.

 

3.H-beam yog dab tsi?

H-beam yog steel qauv uas zoo li nws lub npe qhia tias nws yuav tsum saib: Nws yog steel beam zoo li lub peev H. Cov kab hluav taws xob no ua los ntawm cov hlau dov muab cov txiaj ntsig zoo ntawm lub zog thaum siv hauv kev lag luam hauv tsev. Feem ntau ntawm cov tsev hlau niaj hnub no siv H-beams.

 

4.Vim li cas steel beam H zoo li tus?

H zoo li steel beam yog ib qho kev lag luam thiab siab -kev ua tau zoo profile nrog ntau optimized cross-sectional faib thiab ntau tsim nyog lub zog- rau - luj piv. Steel H beam yog lub npe vim hais tias nws cov seem yog tib yam li ntawv Askiv "H".

 

5.Puas yog I lossis H beam muaj zog dua?

Txawm hais tias kuv -beams tuaj yeem tiv thaiv cov buckling hauv zos, lawv yuav tsis muaj peev xwm tswj tau tib lub zog ib yam li H-beam vim lawv cov qauv sib dua. Zuag qhia tag nrho, lub npe ntawm "Ntaus Beam" mus rau H-beams. Ib qho H-beam's durability los ntawm nws lub zog- mus rau - qhov hnyav piv nyob rau hauv tus ntoo khaub lig- ntu.
