Xav tau pov thawj tiasS320GD galvanized hlauua nyob rau hauv hnyav ntug hiav txwv dej / offshore ib puag ncig? Tsis zoo li cov neeg muab khoom lag luam uas tsis muaj cov ntaub ntawv - ntiaj teb tiag, GNEE qhia cov ntaub ntawv ntxaws ntxaws txog kev kawmS320GD + Z275 hlaunyob rau hauv ib tug ntug dej hiav txwv infrastructure project- ua pov thawj nws corrosion kuj thiab cov qauv kev ntseeg tau.
Peb muab customizedS320GD + Z275 hlau(3.0-8.0mm thickness, 1200-2500mm dav) rau qhov project no, nrog rau tag nrho ua ntej - thiab tom qab-installation xeem. Nyeem rau kom paub seb nws ua tau zoo npaum li cas cov kev cia siab hauv cov dej hiav txwv nplua nuj nyob hauv ntug dej hiav txwv.
Galvanized steel yog qhov tseem ceeb rau kev tsim kho ntug dej hiav txwv / ntug dej hiav txwv, qhov twg ntsev tsuag thiab av noo ua kom corrosion.S320GD galvanized hlauyog qib siab -lub zog muaj zog- nrog Z275 (275g / m² zinc ib sab) xa hnyav- lub luag haujlwm tiv thaiv. Cov ntaub ntawv kawm no qhia meej txog nws qhov kev ua tau zoo 3-xyoo hauv kev ua haujlwm ntawm ntug hiav txwv boardwalk.
Project Background: Coastal Boardwalk Reconstruction
Qhov kev tshawb fawb no tsom mus rau 1.2km ntug hiav txwv boardwalk reconstruction nyob rau hauv ib tug temperate coastal cheeb tsam, qhov twg:
- Qhov nruab nrab txhua xyoo ntsev tsuag raug:Siab (1-3km ntawm dej hiav txwv qhib)
- Qhov nruab nrab txheeb ze humidity:75-85%
- Tsim kev pab cuam lub neej:20+ xyoo
- Qhov xav tau tseem ceeb:Zero loj corrosion nyob rau hauv 5 xyoos
Qhov project xav tau 280 tons ntawm cov qauv hlau, nrogS320GD + Z275 hlauxaiv rau kev thauj khoom- cov kabmob thav duab, railings, thiab lawj kev txhawb nqa- hloov cov qauv Z120-coated steel uas ua tsis tiav hauv 8 xyoo.
S320GD + Z275 Steel Specifications rau ntug dej hiav txwv Project
CovS320GD + Z275 hlausiv nyob rau hauv qhov project no ua tau raws li cov kev cai nruj, raws li tau teev tseg hauv qab no:

| Ntsev Txau Resistance | ASTM B117 (laboratory re- xeem) | Tsis muaj xeb liab tom qab 1200h | Ntau tshaj lossis sib npaug rau 1000h (ntau tshaj) |
CovS320GD + Z275 hlaupom 70% tsawg txheej degradation dua li yav dhau los Z120 steel siv nyob rau hauv tib qhov chaw.
Qhov Tseem Ceeb Ua Tau Zoo: Vim Li Cas S320GD + Z275 Hlau Ua Tau Zoo
Peb yam ua rau muaj kev vam meej ntawmS320GD + Z275 hlaunyob rau hauv qhov project ntug hiav txwv dej:
- Thicker Z275 Txheej: 275g / m² zinc muab 125% kev tiv thaiv ntau dua li txheej txheem Z120.
- Kev tswj cov tshuaj muaj pes tsawg leeg: Tsawg phosphorus / sulfur minimized pitting corrosion hauv dej ntsev.
- Synergistic Txheej System: Zinc primer + topcoat ua hauj lwm nrog Z275 los tsim ib tug multi- txheej thaiv.
Qhov kev tshawb fawb no ua pov thawjS320GD + Z275 hlauxa cov kev ua tau zoo tshwj xeeb hauv kev tsim kho ntug dej hiav txwv / sab ntug dej hiav txwv-kev sib ntsib 3- xyoo corrosion lub hom phiaj thiab tshaj li cov qauv tsim. Nws Z275 txheej thiab optimized muaj pes tsawg leeg ua rau nws ib tug txhim khu kev qha xaiv rau ntsev-nplua nuj ib puag ncig.
Ntawm GNEE, peb muab qhov project- pov thawjS320GD + Z275 hlaunrog tag nrho cov ntaub ntawv ua haujlwm.Tiv tauj peb hnub no kom thov cov ntaub ntawv kawm tiav thiab cov lus hais rau S320GD galvanized steel rau koj qhov dej hiav txwv / ntug dej hiav txwv.
