S280GD Galvanized hlau
S280GD Galvanized Steel yog cov qauv steel qib uas ua los ntawm kub-dip galvanizing, qhov chaw tiv thaiv zinc txheej yog siv rau cov hlau nto. Cov txheej txheem no ua kom muaj zog tiv thaiv corrosion thaum tuav lub zog txhua yam.
S280GD yog ib qho muaj zog, qis- alloy structural steel uas tau siv dav hauv kev tsim kho thiab tsim khoom. Nrog rau qhov tsawg kawg nkaus tawm lub zog ntawm 280 MPa, nws yog qhov nyuaj txaus rau kev xav tau cov haujlwm ua haujlwm. Qhov kub-dip zinc txheej muab kev tiv thaiv zoo tshaj plaws tiv thaiv corrosion, lav kev ua haujlwm ntev. Ua tsaug rau qhov kev sib xyaw ua ke ntawm lub zog thiab kev tiv thaiv, S280GD yog qhov zoo tshaj plaws rau cov txheej txheem thav duab, vov tsev, thiab lwm yam kev siv hnyav -.
Qib S280GD feem ntau xaiv rau cov haujlwm uas xav tausiab zog tshaj S250GD, tab sis tseem xav tau kev tsim muaj peev xwm thiab qhov zoo ntawm qhov chaw.
Chemical and Structural Basis ntawm S280GD
Thaum S280GD feem ntau txhais los ntawm kev ua haujlwm ntawm kev ua haujlwm, nws cov tshuaj muaj pes tsawg leeg tswj xyuas kom ruaj khov zoo thiab ua haujlwm zoo ib yam.
| Lub ntsiab | Hom Lub Luag Haujlwm |
|---|---|
| Cov pa roj carbon (C) | Tswj lub zog thiab weldability |
| Manganese (Mn) | Txhim kho toughness |
| Silicon (Si) | Txhawb txheej adhesion |
| Zinc Txheej | Kev tiv thaiv corrosion |
Qhov sib npaug sib npaug no tso cai rau S280GD Galvanized Steel yuav tsum tau welded, tsim, thiab ua tiav yam tsis muaj kev nyuaj siab - kho.
Zinc Txheej Options thiab Surface Quality
Ib qho txiaj ntsig tseem ceeb ntawm S280GD Galvanized Steel yog qhov muaj ntau cov zinc txheej hnyav thiab cov qauv saum npoo.
| Txheej hom | Kev siv yam |
|---|---|
| Z100–Z275 | Kev tsim kho dav dav |
| Tsis tu ncua Spangle | Cov yam ntxwv ntawm cov khoom |
| Minimized Spangle | Pom qhov chaw |
| Zero Spangle | Painting thiab profileing |
Zinc txheej tsis tsuas yog tiv thaiv cov hlau, tab sis kuj txhim kho cov tsos thiab kev pab lub neej.
Kev sib piv: S280GD vs Lwm Cov Qib Galvanized
Xaiv qhov raug qib steel feem ntau suav nrog kev sib piv. Hauv qab no yog ib qho piv txwv ntawm S280GD Galvanized Steel nrog ntau lwm txoj hauv kev.
| Qib | Yield zog | Daim ntawv thov |
|---|---|---|
| xwm 51d | Tsawg | Tsim -cov khoom tsom |
| S250 GD | Nruab nrab | Lub teeb qauv |
| S280 GD | Nruab nrab-High | Qauv & industrial |
| S350 GD | Siab | Heavy-cov qauv ua haujlwm |
S280GD tuav txoj haujlwm zoo, muabtus nqi- txhim kho lub zog zootsis txav mus rau hauv siab - zog, nyuaj- rau - cov qhab nia.
Cov ntawv thov ntawm S280GD Galvanized Steel
S280GD Galvanized Steel yog dav siv hauv:
- Steel vaj tse thiab thav duab
- ru tsev thiab phab ntsa cladding systems
- Purlins thiab tiab
- Cable tais thiab kev txhawb nqa tshuab
- Agricultural thiab industrial chaw
Nws corrosion kuj ua rau nws haum rau ob qho tib si sab hauv tsev thiab sab nraum zoov ib puag ncig.
Vim li cas S280GD yog qhov kev xaiv txhim khu kev qha
Los ntawm kev tsim engineering thiab kev tsim khoom, S280GD Galvanized Steel muab:
- Stable mechanical zog
- Zoo heev zinc txheej adhesion
- Lub neej ua haujlwm ntev
- Cov kev xaiv ua tau yooj yim
GNEE STEEL tsom rau kev muab S280GD Galvanized Steel nrog cov khoom zoo ib yam, tswj cov tuab tuab, thiab cov txheej txheem txhim khu kev qha los txhawb kev ua haujlwm ntev -.
