S250GD + Z kub dip galvanized hlau
S250GD + Z kub dip galvanized daim hlau (coils) yog featured nrog lub zog txheej adhesiveness, siab erosion -kuj, raug tswj zinc txheej thickness, siab precision, tiaj profile thiab zoo mechanical, ua thiab vuam kev ua tau zoo. Lawv tuaj yeem siv los ua rau sab nrauv thiab sab hauv tsheb daim hlau, cov khoom siv thiab cov khoom siv ntxiv.
Nrog lub zog tensile ntawm 250 MPa, S250GD tuaj yeem tswj cov kev ntxhov siab tseem ceeb. Cov txheej zinc txhim kho nws cov kav ntev, ua rau nws tsim nyog rau kev siv sab nraum zoov thiab txuas ntxiv cov khoom lag luam thaum txo cov kev xav tau ntawm kev saib xyuas.
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.

S250GD + Z kub dip galvanized automotive steel nto kho:
1 Kev kho chromate (L) |
Kev kho chromate yog kev kho mob nrog lub hom phiaj los tiv thaiv cov xeb dawb tsim ntawm cov khoom siv thaum lub sij hawm thauj mus los thiab khaws cia. |
|
2 Cov roj (Y) |
Oiling yog los tiv thaiv cov xeb dawb tsim ntawm cov khoom siv thaum lub sij hawm thauj mus los thiab khaws cia. |
|
3 Kev kho chromate + oiling (LY) |
Qhov kev kho no nrog oiling tom qab kev kho deg chromate yog ntxiv kom tsis txhob muaj cov xeb dawb. |
