H - Cov hlau outsperforms ntoo kab teeb meem hauv qhov chaw noo (hauv cov chaw ua haujlwm noo), nrog kev pabcuam noo noo), nrog kev pabcuam noo noo), nrog rau lub neej noo noo), nrog lub neej kev pab cuam ntawm 20 {}} 30 xyoo. H - steel, los ntawm kev sib piv, tiv taus}}}} nrog arti- corrosion kho). Ntoo tseem plam lub zog thaum lub sijhawm (piv txwv li, 20% lub zog poob tom qab 15 xyoo}}} steel retains 90% + ntawm nws lub zog qub yog tswj. Rau cov phiaj xwm sab nraum zoov (piv txwv li, ua si pavilions, ua si pavilions), h- tus hlau tsis xav tau cov ntoo. Thaum ntoo yog pheej yig dua upfront, h- steel tus nqi kho tus nqi thiab lub neej ntev dua ua tau ntau dua {23}.
Yuav ua li cas h - me steel nqaj tsawg thiab tsawg haum rau qhov chaw tsim khoom loj me?
Rau qhov chaw nqaim (piv txwv li, Nroog Alleitch Adyas, Basadion txhawb), h -} steel sivSlim - profile seemnrog txo cov flange dav. Examples include H150×75×5×7 (flange width 75mm) or H200×80×5.5×8 (80mm flange width)-narrow enough to fit 100-150mm gaps between walls. Qhov ntau thiab tsawg pab tau lub h- duab lub nra muaj peev txheej ntawm cov tswv yim web thickness (5 {} 5.5mm) kom tsis txhob muaj lub zog txi. Tsis zoo li dav - flange boss, slim H-ntu tshem tawm qhov kev xav tau ntawm qhov kev hloov kho qhov chaw (piv txwv li, phab ntsa txiav). Lawv muaj ntau nyob rau hauv lub tsev qub retrofits, qhov chaw muaj kev sib cav sib ceg ntau dua cov qauv hlau.
Vim li cas h- steel ib qho kev xaiv zoo dua li pob zeb rau cov phiaj xwm nrawm?
H -} cov hlau ua haujlwm nrawm hauv peb txoj kev tseem ceeb: Ua ntej,Ua ntej - fabrication- kab teeb yog txiav, drilling, thiab welded tawm- Thib ob,Kev Tuav Tes Taw{{0-}} h} h300} × × 150) yog yooj yim dua rau cov pob zeb sib xws ntawm lub zog zoo sib xws, ua kom nrawm dua. Thib peb,tsis muaj lub sijhawm kho{{0- h-}} Tus Hlau yog npaj los siv tam sim ntawd tom qab kev teeb tsa tau 7 {- Piv txwv li, 10,000㎡ warehouse siv h - cov hlau tuaj yeem ua kom tiav hauv 4 lub lis piam, piv txwv li cov chaw ruaj ntseg, pop-up kev lag luam chaw).
Dab tsi yog cov neeg qaug zog tsis kam ntawm h - cov nqaj hlau, thiab vim li cas nws muaj teeb meem?
Qoob nkees ua rau h - hlau muaj peev xwm tiv taus cov khoom ntim (piv txwv li, kev cai co) tsis muaj kev tawg. Feem ntau h -} cov qhab nia steel (piv txwv li, Q355, S355JR) muaj aQaug zog tsis pub tshaj ntawm ~ 120-150 MPa{{0- Lub ntsiab lus lawv tuaj yeem lis 10 lab + thauj mus los hauv qib kev ntxhov siab no yam tsis muaj kev poob haujlwm. Qhov teeb meem no rau dynamic {{4} Cov phiaj xwm siv h}- steel vim tias lub tsheb hnyav tsis muaj zog rau cov qauv. Muaj cov tshuab ua ke ntawm nws kom tiv thaiv kev co los ntawm cov motors lossis presses. Phom chim qaug zog ua ntej ua ntej ua ntej, yog li engineers xaiv h} xws li en 1993 - 1-9) rau cov ntawv thov siab thauj khoom.
Puas yog h - Co kas steel siv hauv kev ua liaj ua teb cov khoom?
Yog lawm, h -} steel yog dav siv nyob rau hauv kev ua liaj ua teb rau nws lub durability thiab thauj khoom muaj peev xwm:Ua liaj ua teb sheds / Cia{{0- h - Tus txheej txheem hlau, qhib, nrog cov daus hnyav hauv cov cheeb tsam txias.Irrigation Tshuab{{0- h - Cov kab hlau loj tuav cov kab loj loj, tiv thaiv cua thiab dej galvanization (nrog galvanization (nrog galvanization).Tsiaj txhu cov chaw{{0- mid mid- loj × 100) tsim lub tsev nyob ruaj khov, tuaj yeem txhawb nqa cov tshuab pub mis. Tsis zoo li ntoo, h - steel tsis rot, warp, lossis nyiam cov kab tsuag (piv txwv li, txo cov nqi kho. Hauv cov teb chaws zoo li Australia thiab Canada, qhov twg ua liaj ua teb nyob qhov chaw loj, h}}} kub}}} new captent cov kab ntawv txhawb nqa nquag, muaj peev xwm siv ntau zaus.
