Daim ntawv thov ntawm S355J0W, S355J2W, thiab S355K2W
1. Advanced Choj Engineering Structures
Weathering steel yog tus qauv kev lag luam thoob ntiaj teb rau ntev - txuas txuas thiab kev hla kev loj. SivS355J2W or S355K2Wtso cai rau cov engineers tsim cov girders loj thiab txhawb nqa trusses uas yuav tsum tsis txhob pleev xim rau lawv 100 xyoo tsim lub neej.
Lub zog tawm los ua kom muaj zog dua, tsim kom muaj txiaj ntsig zoo dua, thaum lub "K2" toughness ua kom tus choj tseem muaj kev ruaj ntseg tiv thaiv kev tawg thaum lub caij ntuj no kub lossis qis dua - zaus vibrations tshwm sim los ntawm cov tsheb hnyav.
Los ntawm kev tshem tawm qhov xav tau rau kev pleev xim rau ib ntus, cov hlau no tiv thaiv kev cuam tshuam kev lag luam kim thiab ib puag ncig kev sib kis los ntawm cov xim pleev xim.
2. Railway Wagons thiab Intermodal Freight Containers
Hauv kev thauj mus los, S355J0W thiab J2W tau txais txiaj ntsig rau lawv lub zog siab - rau - qhov hnyav piv thiab kav ntev.
Railway Wagons:Cov tsheb thauj khoom ua los ntawm S355J0W weathering steel tuaj yeem nqa hnyav dua vim tias cov khoom siv sib xyaw ua ke nyias tsis tau muaj zog dua li cov qauv carbon steel.
Ntim:Rau cov thawv ntim nruab nrab uas raug rau cov huab cua ntsev thiab cov av noo siab thaum caij nkoj hiav txwv, kev tiv thaiv patina ua raws li daim ntaub thaiv mus tas li, cuam tshuam rau lub neej kev pab cuam ntawm lub nkoj thiab txo qhov "tag nrho cov nqi ntawm cov tswv cuab" rau cov tuam txhab logistics.
3. Niaj hnub nimno Architectural Facade Systems
Architects qhia S355J0W corten steel phaj los tsim "nyob" lub tsev hnab ntawv. Tsis zoo li zoo li qub, pleev xim rau qhov chaw, huab cua steel façade hloov zuj zus mus rau lub sijhawm, hloov ntawm cov txiv kab ntxwv sov mus rau qhov sib sib zog nqus, textured chocolate xim av.
Tshaj li kev zoo nkauj, cov tshuab no muab cov thermal stability zoo thiab hluav taws kub. Tus kheej- kho qhov xwm txheej ntawm patina ua kom ntseeg tau tias txawm tias lub vaj huam sib luag raug khawb hauv qhov siab - tsheb thauj neeg hauv nroog, nws yuav rov tsim nws cov txheej txheem tiv thaiv, tswj lub tsev qhov muag pom kev thiab kev ncaj ncees rau ntau xyoo.
4. Toj roob hauv pes tsim thiab Iconic nroog Sculpture
Cov organic, earthy tones ntawm S355 weathering steel ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev sib koom ua ke ntawm txiv neej- ua cov qauv rau hauv ib puag ncig ntuj. Nws yog dav siv rau hnyav- lub luag haujlwm khaws cov phab ntsa, tsa cov cog ntoo, thiab kev teeb tsa pej xeem kos duab.
Vim hais tias cov khoom yuav tsum tsis txhob muaj tshuaj kho mob los yog tshuaj lom los tiv thaiv - xeb txheej, nws yog ib puag ncig zoo rau siv nyob rau hauv cov chaw ua si thiab dej- tej yaam num nyob ib sab.
Nws lub peev xwm los ua laser-txiav thiab txias- tsim tso cai rau cov neeg ua yeeb yam tsim cov duab zoo nkauj, ruaj khov monuments uas tiv taus cov ntsiab lus yam tsis tau poob lawv cov duab kos duab.
5. Offshore Platforms thiab Industrial Infrastructure
Hauv thaj chaw muaj kev lag luam hnyav thiab thaj chaw nyob sab nraud, cov qauv hlau yog qhov yooj yim rau degradation sai.S355K2Wweathering steel phaj tshwj xeeb yog siv nyob rau hauv cov sectors vim nws superior cuam tshuam tsis kam ntawm -40 degree.
Nws muaj nyob rau hauv kev tsim cov roj thiab roj platform Cheebtsam, muaj chimneys (stacks), thiab cia silos. Cov qauv no feem ntau nyob rau hauv siab - av av los yog tshuaj lom neeg aggressive qhov chaw uas tu yog txaus ntshai thiab kim.
Weathering steel lub peev xwm los tiv thaiv "pitting" thiab sib sib zog nqus- zaum corrosion ua rau nws yog ib qho tseem ceeb ntawm kev ruaj ntseg cov ntaub ntawv nyob rau hauv high - ceg txheem ntseeg ib puag ncig.
6. Kev Loj Hlob Tsis Txaus Ntshai thiab Kev Nyab Xeeb Fencing
Rau qhov loj -tej pej xeem infrastructure zoo li txoj kev loj muaj suab nrov teeb meem thiab kev nyab xeeb railings, S355J0W muab ib qho eco-tus phooj ywg thiab tus nqi- siv tau. Ib txwm galvanized los yog pleev xim rau cov teeb meem nws thiaj li tev thiab yuav tsum tau hloov.
Huab cua steel thaiv, txawm li cas los xij, sib txuas seamlessly rau hauv txoj kev struts thiab nyob twj ywm tu- pub dawb rau tag nrho lawv lub neej. Lawv tsis tso cov tshuaj phem mus rau hauv av, ua rau lawv nyiam xaiv rau "Green Infrastructure" tej yaam num tsom txo cov pa roj carbon hneev taw ntawm lub teb chaws txoj kev loj.
S355J0W steel phaj tseem yog qib siv dav tshaj plaws hauv EN 10025-5 weathering steel vim nws qhov sib npaug zoo ntawm lub zog, kev tiv thaiv corrosion, thiab kev ua haujlwm zoo. Piv nrog S355J2W thiab S355K2W, nws muaj ntau yam kev ua tau zoo tshaj plaws rau kev siv engineering thiab architectural.
