ST45 precision seamless yeeb nkab yog cov hlau tsis tshua muaj seamless steel yeeb nkab ua los ntawm kev kos duab txias lossis txias dov, uas yog dav siv hauv hydraulic systems, tsheb tsim, mechanical engineering, tshuab cuab yeej thiab cuab yeej tsim khoom.
ST45 precision yeeb nkab feem ntau yog xa nyob rau hauv lub xeev ntawm pickling thiab phosphating kom ntseeg tau tias cov nto tiav thiab corrosion kuj ntawm cov yeeb nkab steel.

FAQ
Q. Koj puas muab cov qauv dawb?
Yog lawm, peb tuaj yeem muab cov qauv dawb rau kev kuaj, thiab tus neeg yuav khoom yuav tsum them tag nrho cov nqi xa khoom.
Q. Koj lub sijhawm xa khoom ntev npaum li cas?
Feem ntau hais lus, yog tias muaj Tshuag, lub sijhawm xa khoom yog 3-7 hnub; yog tias tsis muaj Tshuag, lub sijhawm xa khoom yog 7-15 hnub, lub sijhawm tshwj xeeb yog nyob ntawm qhov ntau.
Q. Peb ua li cas thiaj ua tau qhov zoo?
Ua ntej ntau lawm, ib txwm muab cov qauv ua ntej ua ntej; ib txwm ua qhov kev soj ntsuam zaum kawg ua ntej xa zaub mov. Peb kuj tuaj yeem lees txais kev tshuaj xyuas thib peb thiab cais tawm.
Q. Vim li cas koj yuav tsum yuav los ntawm peb tsis yog lwm tus neeg muag khoom?
GNEE Group tsim cov yeeb nkab steel ntau yam, txhawb kev hloov kho, thiab muab kev sim, ntim, kev thauj mus los thiab lwm yam kev pabcuam.
Q. Koj cov nqe lus them nqi yog dab tsi?
Peb lees txais T / T, L / C, Western Union, thiab lwm yam.
Txoj kev them nyiaj tuaj yeem sib tham los ntawm ob tog raws li qhov xwm txheej tiag tiag.
