Stkr490, nrog nws lub zog siab dua, feem ntau siv nyob rau hauv cov ntawv thov lub peev xwm, xws li hauv kev nce siab tsim, txuas hniav, thiab tshuab hnyav.
Stkr400 feem ntau siv nyob rau hauv cov qauv kev tsim kho uas muaj zog siab tsis yog qhov tseem ceeb.
Cov kev sib txawv no hauv cov khoom siv neeg kho tshuab thiab cov khoom siv tshuaj lom neeg ua rau cov ntawv thov sib txawv vim nws lub zog ua kom muaj zog dua thiab muaj zog dua.
Nov yog qee cov ntawv thov tseem ceeb:
1. Kev Tsim Kho Qauv:Stkr490 Cov ntu hauv kev tsim kho ntawm ntau hom ntawm ntau lub tsev, suav nrog rau cov tsev nyob nruab nrab thiab qis dua. Lawv tau siv cov kab teeb, txhua, thiab kab ntawv-nqaj qauv, nrog rau cov plag tsev thiab ru tsev.
2. Cov Machinery Ua:Cov seem hollow yog ua haujlwm hauv kev tsim khoom ntawm kev lag luam machinery, noj kom zoo dua lawv lub zog siab thiab lub zog.
3. Ntim:Stkr490 cov ntu tawm yog siv hauv kev tsim kho cov thawv, tau txiaj ntsig los ntawm lawv kev tawm tsam los deformation thiab corrosion.
4. Hall cov qauv:Lawv kuj tau siv hauv kev tsim kho ntawm Hall Lall cov qauv, muab kev txhawb nqa thiab kev ruaj khov.
5. Ntughore ROJ TEB Teb:Stkr490 cov ntu tawm tau thov rau hauv cov roj offshore cov qauv tsim, qhov uas muaj zog thiab tawm tsam mus rau ib puag ncig hnyav yog qhov tsim nyog.
6. Hiav Txwv Trestle:Cov ntu hollow yog siv hauv kev tsim kho hiav txwv lossis jetties, uas xav tau cov ntaub ntawv uas tuaj yeem tiv thaiv cov pob zeb ntawm cov tub rog ib puag ncig.
7. Motorcar Chassis:Stkr490 cov hlau siv rau hauv kev tsim khoom ntawm Motorcar Chassis vim nws lub zog siab thiab kev nyab xeeb.
8. Lub tshav dav hlau qauv:Cov hlau kuj tseem siv hauv tshav dav hlau qauv, qhov uas xav tau cov ntaub ntawv muaj zog thiab ntseeg tau yog qhov tseem ceeb.
9. Nkoj:Stkr490 cov seem tau siv nyob rau hauv cov kab mob nkoj rau ntau cov txheej txheem sib txawv uas yuav tsum muaj zog thiab ua rau Maritime tej yam.
10. Tsheb cov kav dej:Cov qib steel yog siv nyob rau hauv kev tsim cov khoom lag luam ntawm cov kav hlau, qhov uas muaj lub zog siab thiab lub zog yog qhov tseem ceeb.
Cov ntawv thov no qhia txog cov versatility thiab qhov tseem ceeb ntawm stkr490 hollow seem steel nyob rau hauv kev muab kev pab qauv kev cai thiab kev ua haujlwm ntev thoob plaws hauv ntau ntawm kev lag luam.
Nov yog qee qhov kev kho nyob saum npoo av rau Stkr490 Hollow tshooj:
1. Hmoov Txheej: Nws muab txoj kev du thiab ruaj, muab cov kev tiv thaiv zoo heev rau kev xeb, puas tsuaj, thiab fading.
2. Kub-DIP Galvanized:Tus txheej txheem no cuam tshuam cov hlau nrog ib txheej ntawm zinc, uas muaj kev tiv thaiv zoo heev tiv thaiv xeb thiab xeb.
3.Qhov khoom pleev xim:Ua ntawv thov lub tsho tiv thaiv primer tuaj yeem muab cov txheej txheem xim ntxiv thiab txhim kho cov hlau ua kom tsis kam rau corrosion, tshwj xeeb tshaj yog siv nyob rau ib puag ncig sab nraum zoov lossis drippy.
Cov kev kho mob saum npoo no pab txuas ntxiv txoj haujlwm lub neej ntawm Stkr490 hollow seem stect hlau thiab xyuas kom meej tias nws ua tau zoo nyob rau hauv ntau yam kev siv. Cov khoom no tuaj yeem muab kev ua tau zoo thiab ruaj khov rau ntau yam kev tsim kho thiab cov ntawv thov.
