Kub-dip galvanized steel
Kub-dip galvanized steel S250GD raws li EN 10346 tus qauv yog siab-cov qauv hlau zoo uas tau tsim tshwj xeeb rau kev siv hauv kev tsim kho. Nrog rau cov khoom siv tooj 1.0242, S250GD muaj qhov tsawg kawg nkaus yield zog Rp0.2 ntawm 250 N / mm² thiab yog li muab faib nyob rau hauv nruab nrab lub zog chav kawm ntawm kub -dip galvanized structural steels. EN 10346 tus qauv tsis tsuas yog qhia txog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab, tab sis kuj txhais cov txheej txheem kub -dip galvanizing uas tsim kom muaj kev tiv thaiv ib puag ncig zinc txheej ntawm cov hlau. Cov txheej txheej muaj + Z, + ZF, + ZA, + ZM, + AZ thiab + AS ua kom muaj kev yoog raws qhov sib txawv ntawm ib puag ncig thiab cov xwm txheej thauj khoom.

Nta
S250GD galvanized steel ntawv / daim hlau tuaj yeem nqa cov txiaj ntsig hauv qab no rau koj qhov project:
- Muaj zog tiv thaiv xeb-Cov txheej txheej galvanized pab nws kav ntev.
- Ua kom kawg- Nws muaj lub zog zoo rau kev siv hnyav -.
- Yooj Yim Ua Haujlwm Nrog- Yooj yim rau txiav, vuam, thiab ua raws li xav tau.
- Saib Zoo- Lub ntsej muag du uas yooj yim pleev xim, txhim kho nws cov tsos.
- Nyiaj txiag -Poj niam- Muaj txiaj ntsig zoo rau kev ua haujlwm.
- Lub teeb- Yooj yim rau thauj thiab nruab yam tsis muaj teeb meem ntxiv.
- Eco-Nyob zoo- Ua los ntawm cov khoom siv rov ua dua tshiab, txhawb kev ruaj khov.
Daim ntawv thov Scenario
S250GD + Z galvanized steel ua tau zoo tshwj xeeb hauv cov cheeb tsam hauv qab no:
1. Cov khoom siv hauv tsev
Galvanized steel sheets yog ib qho tseem ceeb rau kev tsim kho niaj hnub vim lawv txoj kev ntseeg siab thiab kev ua haujlwm ntev.
- Lub ru tsev decking thiab phab ntsa cladding
- Load-cov kabmob purlins thiab kab
- Secondary framing rau curtain phab ntsa
Cov vaj tsev raug kev nyab xeeb ntawm ntug dej hiav txwv lossis kev muaj kuab paug muaj txiaj ntsig tau txais txiaj ntsig los ntawm kev tiv thaiv galvanization, pab tiv thaiv xeb thiab kev puas tsuaj ntawm cov qauv.
2. Cov qauv kev ua liaj ua teb thiab ua liaj ua teb
Cov chaw ua liaj ua teb xav tau cov ntaub ntawv uas tiv taus cov av noo thiab tshuaj lom neeg los ntawm cov chiv thiab tsiaj pov tseg. S250GD + Z feem ntau siv hauv:
- Barn siding thiab ru tsev
- Cov tsiaj txhu enclosures
- Pub cov qauv cia
- Cov cuab yeej cuab tam
Cov txheej ruaj ruaj txo lub sijhawm txij nkawm, tso cai rau cov neeg ua liaj ua teb tsom mus rau kev ua haujlwm ntau dua li cov teeb meem corrosion.
3. Hnub ci ua liaj ua teb thiab txuas txuas ntxiv
Nrog rau qhov nce ntawm cov haujlwm txuas ntxiv hluav taws xob, cov khoom siv hluav taws xob galvanized tau nce ntxiv rau:
- Hnub ci vaj huam sib luag mounting ntas
- Txhawb cov qauv rau kev taug qab cov tshuab
- Lub teeb- hnyav galvanized arrays
Kev sib xyaw ua ke ntawm kev tiv thaiv corrosion thiab lub zog ua kom lub neej ntev kev pab cuam nyob rau hauv sab nraum zoov lub zog installation.
