Cov txheej txheem galvanized steel ntawv
S250GD + Z stands raws li ib tug benchmark structural galvanized steel ntawv tsim rau daim ntawv thov uas xav tau tshwj xeeb corrosion kuj thiab txhim khu kev qha mechanical kev ua tau zoo. Lub "S250" tawm los lub zog thiab zinc txheej muab los ntawm cov khoom no ua rau nws haum rau ib puag ncig uas huab cua, noo noo, thiab puas yog kev txhawj xeeb. Nrog ntau txoj kev kho deg - suav nrog spangle variations thiab passivation khaubncaws sab nraud povtseg - qib no tsis yog tsuas yog haumxeeb tab sis kuj adaptable rau aesthetic xav tau.
Qhov zoo ntawm S250GD
- siab dua corrosion kuj
- Zoo heev formability
- Tsawg crack susceptibility ntawm txheej
- Tawm taw tes ntawm 250 N / mm² rau siab zog, siab corrosion kuj siv qhov chaw.
- Zoo nkauj nto, corrosion kuj, zoo vuam kev ua tau zoo, tej yam stamping kev ua tau zoo, ruaj

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 ntawv yog ib qho tseem ceeb rau kev tsim kho niaj hnub no 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 kev tiv thaiv galvanization, pab tiv thaiv xeb thiab kev puas tsuaj ntawm cov qauv.
2. Agricultural thiab Farm Structures
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 txheem ruaj khov txo lub sijhawm txij nkawm, cia 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 ua haujlwm ntev hauv kev teeb tsa sab nraum zoov.
