Tshooj hlauyog ib hom hlau strip nrog ib qho seem zoo li cas thiab qhov loj me. Nws yog ib qho ntawm plaub hom hlau loj (phaj, raj, hom thiab txhob lo lo ntxhuav). Raws li cov duab ntawm seem, cov hlau seem tuaj yeem muab faib ua cov hlau seem yooj yim thiab cov hlau seem nyuaj (cov hlau zoo li tshwj xeeb). Tus thawj yog hais txog cov hlau square, cov hlau puag ncig, cov hlau tiaj tus, cov hlau kaum sab xis, cov hlau hexagonal, thiab lwm yam.; Tus tom kawg yog hais txog cov hlau I-beam,hlau channel, txoj kev tsheb ciav hlau, qhov rai hlau, khoov hlau, thiab lwm yam.
Cov hlau txuasTsis yog hlau seem, cov hlau rebar yog hlau. Rebar yog hais txog hlau rau cov pob zeb reinforced thiab cov pob zeb reinforced prestressed, thiab nws qhov seem yog puag ncig lossis qee zaum plaub fab nrog cov ces kaum puag ncig. Xws li cov hlau puag ncig, cov hlau ribbed, cov hlau torsion. Cov hlau reinforced concrete yog hais txog cov hlau ncaj lossis disk bar siv rau kev txhawb nqa cov pob zeb reinforced, nws cov duab yog muab faib ua ob hom hlau puag ncig thiab cov hlau deformed, lub xeev xa khoom yog ncaj bar thiab disk puag ncig ob.
Hlau yog siv dav thiab muaj ntau hom. Raws li cov duab sib txawv, hlau feem ntau muab faib ua plaub pawg: profile, phaj, yeeb nkab thiabcov khoom siv hlauCov hlau yog ib yam khoom uas muaj qee yam duab, qhov loj me thiab cov yam ntxwv ua los ntawm cov ingot, billet lossis hlau los ntawm kev ua haujlwm siab. Feem ntau cov hlau ua los ntawm kev ua haujlwm siab, yog li cov hlau ua tiav (billet, ingot, thiab lwm yam) tsim cov yas deformation. Raws li qhov kub ua tiav hlau sib txawv, muaj peev xwm muab faib ua kev ua txias thiab kev ua kub.
Yog tias koj xav tau cov khoom no, koj tuaj yeem nyem rau ntawm kaum sab xis hauv qab, peb yuav tiv tauj koj sai li sai tau.
