Cov hlau uas qhib rau ob hnub thiab muaj lub qhov khoob khoob, thiab nws ntev npaum li cas yog qhov loj ntawm qhov seem, tuaj yeem hu ua steel kav. Thaum qhov ntev yog me me piv rau qhov ntsuas ntawm qhov seem, nws tuaj yeem raug hu ua ib feem ntawm cov yeeb nkab lossis ib qho siv tubular, uas yog txhua yam hauv cov khoom yeeb nkab.
Rau ntau tshaj li rau caum lub xyoo, cov neeg tsim khoom siv tau siv cov xov hlau tsis muaj rab peev xwm los tsim kom muaj nuj nqis rau cov tsev kawm ntawv. Muaj ntau lub tsev uas muaj qauv zoo tshaj qhov qhia txog qhov tseeb ntawm qhov kev xaiv no. Muaj qee yam lom zem heev, xws li Chrysler Building in New York City. Tab sis nyob rau hauv ntau lwm yam kev siv, lub luag hauj lwm ntawm stainless hlau tsis yog li ntawd qhia, tab sis nws plays lub luag hauj lwm tseem ceeb nyob rau hauv lub zoo nkauj thiab kev ua tau zoo ntawm cov tuam tsev. Piv txwv li, txij li lub pas hlau tsis muaj zog hnav thiab tiv thaiv tsis pub hnyav dua lwm yam khoom siv hlau ntawm tib tuab tuab, nws yog cov khoom siv rau cov qauv siv thaum tsim kev taug kev nyob rau hauv qhov chaw uas muaj cov neeg loj dav.
Stainless hlau tau siv ntau tshaj 70 xyoo los tsim cov tuam tsev tshiab thiab cov ntaub ntawv siv los kho kho cov chaw hauv keeb kwm. Cov qauv tsim thaum ntxov tau raug muab xam raws li cov hauv paus ntsiab lus. Niaj hnub no, tsim qauv, xws li American Society of Civil Engineers 'standard ANSI / ASCE-8-90 "Cov Qauv Uas Tsim Cov Qauv Txias Stainless Steel Structural Parts" thiab "Cov Ntawv Txuj Ci Txawj Tsis Tsim Nyog" Cov ntawv luam tawm los ntawm NiDI thiab Euro Inox, tau simplified kev pab lub neej. Tus qauv tsim ntawm cov khoom ua rau kev ntseeg siab zoo.
