structural galvanized hlau
S280GD thiab S320GD yog cov txheej txheem galvanized steel qib teev nyob rau hauvTS EN 10346, dav siv nyob rau hauv kev tsim kho, steel qauv, thiab industrial systems uas yuav tsum tau ob qho tib si mechanical zog thiab corrosion kuj.
Lub npe system yog ncaj nraim:"S"hais txog cov qauv hlau, cov lej280thiab320qhia qhov tsawg kawg nkaus tawm lub zog hauv MPa, thiab"GD"txhais tau hais tias cov hlau raug xa mus rau hauv cov xwm txheej galvanized, feem ntau los ntawm kub -dip galvanizing.
Ob leeg S280GD Galvanized Steel thiab S320GD Galvanized Steel yog tsim los ua kom tau raws li cov txheej txheem niaj hnub no, tab sis lawv cov kev ua tau zoo thiab kev ua haujlwm siab sib txawv hauv kev siv tswv yim.
Mechanical Property Comparison
Qhov sib txawv ntawm lub zog tawm los ntawm S280GD thiab S320GD ncaj qha cuam tshuam rau kev thauj khoom- bearing peev, seem tsim, thiab cov khoom siv tau zoo.
| Mechanical Property | S280 GD | S320 GD |
|---|---|---|
| Yam tsawg kawg nkaus Yield Strength | Ntau dua lossis sib npaug li 280 MPa | Ntau dua lossis sib npaug li 320 MPa |
| Tensile zog | 360-480 MPa | 390-510 MPa |
| Elongation (A80) | Ntau dua lossis sib npaug li 18% | Ntau dua lossis sib npaug li 17% |
| Qeb zog | Nruab nrab | Nruab nrab-siab |
S320GD muab lub zog ntau dua, tso cai rau cov kws ua haujlwm kom txo cov tuab thaum tswj xyuas cov qauv kev nyab xeeb, qhov S280GD muaj kev ua siab ntev me ntsis.
Hauv qhov chaw tsim khoom tiag tiag, kev tsim tus cwj pwm feem ntau ua lub luag haujlwm txiav txim siab hauv kev xaiv qib.
| Txheej Txheem | S280GD Galvanized hlau | S320GD Galvanized hlau |
|---|---|---|
| Txias txoj kev | Zoo heev | Zoo |
| Khoov radius kam rau ua | Dav dua | Nruab nrab |
| Roll forming stability | Siab | Nruab nrab-siab |
| Risk thaum lub sij hawm complex profiles | qis | Me ntsis siab dua |
Rau cov haujlwm uas cuam tshuam nrog cov ntaub ntawv nyuaj lossis kev ua haujlwm ntau zaus, S280GD Galvanized Steel feem ntau nyiam. S320GD, txawm li cas los xij, tseem tsim nyog rau cov txheej txheem tsim cov txheej txheem.
Daim ntawv thov sib txawv
- S280GD Galvanized Steel yog dav siv hauv:
Lub teeb steel qauv
vov tsev thiab phab ntsa cladding systems
Purlins thiab theem nrab framing
- S320GD Galvanized Steel feem ntau xaiv rau:
Nruab nrab- thauj cov tswv cuab cov qauv
Kev lag luam thav duab
Daim ntawv thov yuav tsum tau nruj dua
Qhov kev xaiv nyob ntawm seb puas tsim tau yooj yim los yog lub zog optimization yog qhov kev txhawj xeeb tseem ceeb.
