Raws li kev tsim kho thiab kev lag luam kev lag luam nce ntxiv tsom mus rau qhov ntev - kev cia siab rau lub sijhawm, kev ruaj ntseg zoo tau dhau los ua qhov tseem ceeb hauv kev xaiv cov khoom siv. Ntawm ntau qib galvanized steel,S280GD txheej txheem galvanized steeltxuas ntxiv tau txais kev saib xyuas rau nws cov khoom siv kho tshuab zoo ib yam, txhim khu kev qha zinc txheej kev ua tau zoo, thiab tsim nyog rau kev thauj khoom- cov ntawv thov bearing.
S280GD yog cov txheej txheem steel qib uas tau teev tseg raws li EN 10346, tsim los muab lub zog qis kawg nkaus ntawm 280 MPa thaum tau txais txiaj ntsig los ntawm kub -dip galvanization. Qhov kev sib xyaw ua ke no tso cai rau cov khoom siv kom tau raws li cov qauv kev xav tau thaum tswj kev ua haujlwm zoo corrosion, ua rau nws haum rau ob qho tib si sab hauv tsev thiab sab nraum zoov.
Cov khoom siv steel hlau feem ntau yog siv rau hauv cov tshuab uas muaj kev nyab xeeb cov npoo yog nruj nreem xam. Txhua qhov tsis sib xws ntawm lub zog, tuab, lossis txheej txheej zoo tuaj yeem ua rau muaj kev sib tw thaum lub sijhawm tsim khoom lossis teeb meem kev ua haujlwm tsis txaus siab tom qab kev teeb tsa.
Rau S280GD galvanized steel, zoo sib xws feem ntau tsom rau cov hauv qab no:
| Yam Khoom Zoo | Qhov tseem ceeb hauv kev siv tus qauv |
|---|---|
| Yield zog stability | Xyuas kom paub tseeb tias cov load-kev coj tus cwj pwm |
| Thickness kam rau ua | Txhawb kom raug cov qauv sib dhos |
| Zinc txheej uniformity | Muab kev tiv thaiv corrosion zoo ib yam |
| Deg mob | Yooj yim tsim thiab vuam |
Kev tswj xyuas kev ua haujlwm ruaj khov thoob plaws ntau cov khoom sib txawv tso cai rau cov neeg tsim khoom tsim cov txheej txheem kev ua haujlwm, txo cov khoom pov tseg thiab txhim kho kev tsim khoom.
Piv nrog rau cov qib sib sib zog nqus, S280GD cov qauv hlau muaj kev txhim kho kev nruj, tso cai rau cov neeg tsim qauv kom txo qis seem me me yam tsis muaj kev cuam tshuam txog kev nyab xeeb. Nyob rau tib lub sijhawm, nws tseem ua haujlwm tau ntau dua li siab dua - qib kev ua haujlwm muaj zog, uas feem ntau yuav tsum muaj kev txwv nruj dua.
Qhov sib npaug no ua rau S280GD galvanized steel haum rau:
- Secondary load-cov kabmob
- Cov txheej txheem vov tsev thiab phab ntsa
- Cov cuab yeej siv kho vaj tse
- Prefabricated lub tsev Cheebtsam
Hauv cov ntawv thov no, cov zinc txheej muab ntev - lub sij hawm corrosion kuj, txo qhov xav tau kev kho deg ntxiv tom qab kev teeb tsa.
GNEE STEEL muab qhov tseem ceeb ntawm kev tswj xyuas zoo rau cov khoom siv galvanized steel. Los ntawm kev xaiv cov khoom siv raw mus rau qhov kev tshuaj ntsuam zaum kawg, txhua theem tau ua raws li EN 10346 cov kev cai kom ntseeg tau tias cov tshuab ua haujlwm ruaj khov thiab txhim khu kev qha zoo.
Ntxiv rau S280GD cov txheej txheem galvanized steel, GNEE STEEL muab ntau yam ntawm cov galvanized structural steel qib los txhawb ntau hom kev tsim kho thiab kev lag luam, pab cov neeg siv khoom ua tiav ob qho tib si kev ntseeg siab thiab ntev - tus nqi.
