Cov tsev hlau thiab cov tsev hlaufeem ntau txhais tsis raug nyob rau hauv kev tsim kho kev lag luam raws li ib tug -thiab- cov qauv tib yam; Txawm li cas los xij, cov pawg no sawv cev rau ob pawg qauv sib txawv nrog cov khoom siv sib txawv, cov yam ntxwv ua haujlwm, thiab cov xwm txheej siv.
Ua ntej thiab qhov tseem ceeb, cov khoom siv ntau yam yog qhov txawv ntawm cov tsev hlau thiab cov tsev steel sib nrug. Lub tsev hlau hais txog ib qho qauv ua los ntawm cov hlau alloy - steel, aluminium, tooj liab thiab txawm tias galvanized hlau yog piv txwv. Cov chaw ua liaj ua teb me me tuaj yeem siv cov txhuas alloys rau kev tiv thaiv corrosion thaum lub rooj cob qhia ib ntus tuaj yeem siv qis - nqi galvanized hlau hloov. Conversely, steel tsev sawv cev rau ib tug subset ntawm hlau vaj tse siv tshwj xeeb steel raws li nws cov load bearing khoom xws li carbon steel, stainless hlau los yog siab zog structural steel raws li lawv lub ntsiab load-cov khoom siv bearing- no nqaim txhais ua rau steel tsev txawm ntau tshwj xeeb nyob rau hauv cov hlau tsev tsev neeg dua lawv counterparts.
Qhov thib ob, kev ua tau zoo ntawm cov qauv thiab kev ua haujlwm ntev sib txawv ntawm cov tsev hlau uas tsim los ntawm cov khoom tsis yog- steel xws li txhuas. Cov vaj tse ua nrog cov hnyav no tsis tau xeb- cov hlau tiv taus zoo li muaj peev xwm qis dua- cov kabmob muaj peev xwm; piv txwv li aluminium yog lub teeb yuag, tab sis tsis muaj lub zog tensile tsim nyog rau ntau- zaj dab neeg kev tsim kho. Galvanized hlau tsis muaj zog, nrog kev saib xyuas tas li yuav tsum tau ua kom nws saib nws zoo tshaj plaws. Cov tuam tsev hlau, los ntawm qhov sib txawv, coj kom zoo dua ntawm steel lub zog zoo tshaj - rau - qhov hnyav piv, zoo heev ductility thiab fireproof txheej muaj peev xwm rau kev tiv thaiv hluav taws ntau dua piv rau cov tsev hlau galvanized. Cov tsev hlau muaj peev xwm txhawb nqa cov qauv loj loj (50+ meter clear span warehouses) nrog ntau- zaj dab neeg tsim rau 50-100 xyoo kev pab cuam lub neej, deb tshaj lwm yam kev xaiv lub tsev hlau (xws li 10-30 xyoo lifespan ntawm cov tsev uas tsis yog hlau).
Thirdly, daim ntawv thov scenarios tuaj yeem paub qhov txawv yooj yim. Cov vaj tsev hlau yog qhov zoo tshaj plaws - haum rau me me - nplai thiab qis- cov phiaj xwm nyiaj txiag xws li cov chaw tsheb thauj neeg, vaj tsev thiab cov chaw ua si ib ntus uas tus nqi - kev ua tau zoo thiab kev teeb tsa ceev ua ntej ntev tshaj - lub sij hawm durability. Cov tuam tsev hlau feem ntau ua tau zoo nyob nruab nrab- mus rau- loj- kev lag luam loj, kev lag luam, kev tsim kho vaj tse nrog kev xa khoom warehouses, cov chaw tsim khoom, tshav dav hlau terminals thiab siab- nce chaw ua haujlwm vim lawv muaj peev xwm tiv taus huab cua huab cua (xws li nag xob nag cua / av qeeg / hnyav hnyav), ua rau lawv muaj kev xaiv ntau yam. nag xob nag cua / av qeeg / hnyav loads).
Cov tsev hlau tuaj yeem txhais tau tias yog cov qauv hlau ua los ntawm cov hlau; Txawm li cas los xij, tsis yog txhua lub tsev hlau tsim nyog ua "steel". Txhawm rau sib txawv, cov txheej txheem sib txawv suav nrog cov khoom tshwj xeeb, kev ua haujlwm tau zoo thiab cov ntawv thov scalability uas tso cai rau cov kws tshaj lij tsim kho xaiv cov kev daws teeb meem zoo tshaj plaws raws li qhov project xav tau.
