Cov qauv-qib galvanized steel
S250GD + Z yog cov txheej txheem - qib galvanized steel ntawv engineered rau durability, corrosion kuj, thiab formability. Qib steel no ua raws cov qauv nruj rau kev ua tau zoo hauv qhov xav tau ib puag ncig. Qhov kev xaiv "S250" yog hais txog qhov tsawg kawg nkaus lub zog ntawm 250 MPa, thaum "GD + Z" qhia tias kub -dip galvanized txheej uas muab kev tiv thaiv zoo tiv thaiv atmospheric corrosion. Ua ke nrog kev ua tib zoo xaiv cov yam ntxwv zoo li spangle loj thiab txheej hnyav, S250GD + Z galvanized steel yog dav siv thoob plaws ntau qhov kev lag luam uas xav tau ob qho tib si lub zog thiab ntev - ua tiav kev ua tiav.
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.

1) Qhov twg lub zog tawm los yog txhais, cov txiaj ntsig siv rau lub zog siab zog ReH.
2) Rau txhua hom hlau, tshwj tsis yog S550GD, qhov ntev ntawm 140 MPa tuaj yeem xav tau rau lub zog tensile.
3) Raws li cov khoom thickness, qhov tsawg kawg nkaus qhov tseem ceeb ntawm elongation ntawm pob txha raug txo raws li nram no: 0.50 mm < t < 0.70 mm ( rho tawm 2 units ), 0.35 mm < t < 0.50 mm ( rho tawm 4 units ), thiab t < 0.35 mm ( rho tawm 7 units ).
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 zoo 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.
