Rau cov chaw nyob hauv zej zog me me (10m × 5m, 2-3m qhov siab),H200×100×5.5×8yog zoo tagnrho. Nws qhov siab (200mm) thiab flange dav (100mm) sib npaug lub zog (ntoo av: ~ 1-15} Lub Web Thickness (5.5mm) ua kom nruj rau kev txav mus ib txhis (piv txwv li cov neeg ua yeeb yam txav hla ntawm theem ua kom yooj yim txuas txuas nrog cov screws. Qhov loj me hnyav ~ 27 kg / m, ua rau nws yooj yim rau cov neeg ua haujlwm pab dawb sib dhos / disassemble rau cov xwm txheej. Qhov ntau loj thiab tsawg, h250 × 125) yuav dhau nrawm rau kev tuav tuav, thiab cov me me (piv txwv li 90) tej zaum yuav tsis muaj zog rau cov neeg tuag.
Yog vim li cas h - steel ntau tus nqi -}}}}}}}} Ua tau zoo dua li cov txee hauv chav nres tsheb?
H - steel beats stainless hlau rau chav nres tsheb vim muaj tus nqi qis dua li 5} 4 {{{{{}} 10m txee tshuab. Garage shelves only need to support light-to-medium loads (tools, boxes: ~1-2 kN/m), which H-steel handles easily-no need for stainless steel's extra corrosion resistance or strength. H- Cov hlau tuaj yeem pleev xim (them nqi $ 20 {}}}}}}}}}}}}}}}}}} Zoo li cov steel rau stainless hlau rau cov txee. Piv txwv li, 6M H-steel txee (H-steel txee (H150 × 5) Cov nqi ~ $ 300, thaum Stainless hlau ntawm tib cov nqi loj ~ $ 1,200. H-steel tus nqi-ua tau zoo ua rau nws txoj kev xaiv zoo tshaj plaws rau cov chaw nres tsheb tsis muaj kev lag luam.
Yuav ua li cas h - hlau torsional tawv me me Choj railer me me?
H - Hlau} Tus Hlau Torsional Tiffness (Muaj peev xwm tawm tsam Twisting) yog qhov tseem ceeb rau cov choj me me (neeg taug kev lossis tsheb kauj vab sib txuas lus). Raug h-} hlau (h180 × 5.5 × 5.5 × 5.5 ntawm ~ 25,000 mm⁴, ntau dua li cov hlau. Qhov no txhais tau tias thaum cov nyom ntawm cov neeg taug kev ntawm kev sib tw lossis cua thawb nws, h {10} {tswj kev nyab xeeb thiab cov duab. Txuas hniav me me (5 - 10m spans) ntsej muag kab tom qab (cua, yog li torsionalal triffness txwv tsis pub railing deforming deforming deforming deformation. Tsis zoo li hloov tau yooj yim txhuas railings, h {18 18}} steel lub pob zeb tsis txhob muaj kev hloov kho tas li. Piv txwv li, hauv tus choj hla kev choj taug kev H-steel (H180 × 90) Nyob ncaj rau {xyoo, thaum xav tau kev kho vaj tse thiab xav tau kev kho tom qab 3-5 xyoos.
Puas yog h - cov nqaj me me siv hauv me me- nplai ovaculture tso tsheb hlau luam?
Yog, h {-} hlau yog siv rau cov aquaculture me aquaculture tank thaves, 2-3m qhov siab) nrogH150×75×5×7lossisH180×90×5.5×8ntu. Lub thav ntawv txhawb nqa tank phab ntsa (fiberglass lossis cov yas) thiab tiv taus dej siab (txog 20 kpa rau 2m siab tso tsheb hlau luam). H {{4 4} steel lub zog cia tso tsheb hlau luam 50 {}} 100m³ los yooj yim txuas ntxiv txuas cov tank. Txhawm rau tiv thaiv Aquaculture av noo thiab dej txaws, h- pa galvanized (nqi} {{14- 20 xyoo. Tsis zoo li ntoo ntas, H-steel tsis rot lossis nyiam cov kab tsuag, txo qis kev txij nkawm. Cov ntses ntses me me hauv Asia thiab Africa feem ntau siv H-steel rau nws cov kav ntev thiab tus nqi qis piv rau stainless hlau.
Lub teb chaws sab hnub tuaj Europe Eastern uas siv h -} cov hlau rau cov tsev kawm ntawv nyob deb nroog?
Sab Hnub Tuaj European lub teb chaws zoo liHungary, Romania, thiab Bulgariavam khom h - cov hlau rau kev tsim kho nyob deb nroog. Hungary siv h- steel rau cov tsev kawm ntawv me me (1} Nws yooj yim Fabrical ceev nce rau hauv thaj chaw deb. Romania siv h - steel rau tsev kawm ntawv nthuav dav (ntawm breat txias - kub cov qhab nia zoo li S355Jo) zoo dua li ntoo. Bulgaria siv h- cov hlau rau lub xeev tsev kawm ntawv nyob deb nroog, txuas ntxiv ntawm lub teb chaws Yelemees (tau hais tawm los ntawm Tebchaws Yelemees thiab Poland) kom haum cov peev txheej hauv zos. Cov teb chaws cov no ua rau H-steel rau cov tsev kawm nyob deb nroog (tseem ceeb rau cov xyoo sijhawm kawm ntawv) thiab ruaj khov txaus rau {xyoo ntawm kev siv.
