FAQs

• Q: Dab tsi thoob ntiaj teb cov qauv ua koj cov khoom ua raws?

  Peb cov khoom lag luam tag nrho yog ISO 9001-certified thiab ua raws li EU CE cov lus qhia. Cov ntawv pov thawj tseem ceeb suav nrog:
  - Cov qauv hlau: ISO 4996: 2014 EN
  Galvanized hlau: ASTM A653 / EN 10346
  - Tinplate: FDA 21 CFR 175.300 zaub mov-qib ua raws
  - Cov khoom lag luam: Txhawb 20+ cov qauv thoob ntiaj teb (JIS, GB, DIN, thiab lwm yam)
  

• Q: Koj cov txheej txheem pickling / electroplating / galvanizing yuav ua li cas kom ntseeg tau qhov chaw
  zoo?

  A: Peb siv ntau theem tu, nruab nrab, thiab kaw-voj tswj tshuab (piv txwv li, Sa 2.5 huv si rau pickled coils, nanocrystalline txheej rau cov khoom siv electro-galvanized) los xyuas kom meej oxide-dawb, cov xim tsis sib xws raws li ISO / ASTM cov qauv.

• Dab tsi yog qhov tensile/yield zog lossis hardness qhov tseem ceeb ntawm cov khoom?

  A: Cov khoom sib txawv ntawm cov txheej txheem (piv txwv li, txias-hardened coils: 1,200 MPa tensile zog; Zn-Fe alloy txheej: 150-220 HV hardness). Cov ntaub ntawv ntxaws ntxaws muaj nyob rau hauv kev specifications lossis raws li kev thov.

• Q: Yuav ntim thiab thauj li cas?

  A: Kev ntim khoom: Cov ntawv pov thawj dej tsis muaj dej + steel band khi, lossis ntim ntim raws li cov neeg siv khoom xav tau (xws li rooj ntoo, cov yeeb yaj kiab tsis muaj dej);
  Txoj kev thauj mus los: kev thauj mus los, kev tsheb ciav hlau, kev thauj mus los hauv hiav txwv. Peb tuaj yeem pab hauv kev sib cuag logistics lossis xa khoom raws li kev xa khoom raws li tus neeg siv khoom.

• Q: Cov khoom puas ua raws li cov qauv kev tiv thaiv kev nyab xeeb?

  A: Yog. Cov khoom xws li tinplate thiab cov electro-galvanized coils yog FDA 21 CFR 175.300 tau ntawv pov thawj rau cov khoom noj ncaj qha / ntim tshuaj.

• Q: Cov ntaub ntawv dab tsi yog siv rau koj cov kub dov steel coils?

  A: Cov khoom siv: Q235B, Q355B, SS400, SPHC, Q345D, thiab lwm yam.
  Cov khoom siv tshwj xeeb tuaj yeem muab tau (xws li cov pa roj carbon siab, tsis tshua muaj alloy siab zog steel, thiab lwm yam).

• Q: Koj ua li cas kom paub tseeb tias cov khoom tsis raug kuaj pom thiab sib xws?

  A: Tag nrho cov txheej txheem kev tswj hwm zoo suav nrog kev ntsuas tam sim no (> 0.1 hli txhawm rau kuaj pom), ntsuas tuab, thiab ntsuas tshuaj ntsev. Txhua lub kauj yog muab nrog Daim Ntawv Pov Thawj Kev Xeem Khoom (MTC) thiab daim ntawv tshuaj xyuas.

• Q: Cov ntaub ntawv dab tsi yog siv rau koj cov kub dov steel coils?

  A: Cov khoom siv: Q235B, Q355B, SS400, SPHC, Q345D, thiab lwm yam.
  Cov khoom siv tshwj xeeb tuaj yeem muab tau (xws li cov pa roj carbon siab, tsis tshua muaj alloy siab zog steel, thiab lwm yam).

• Q: Koj ua li cas kom paub tseeb tias cov khoom tsis raug kuaj pom thiab sib xws?

  A: Tag nrho cov txheej txheem kev tswj hwm zoo suav nrog kev ntsuas tam sim no (> 0.1 hli txhawm rau kuaj pom), ntsuas tuab, thiab ntsuas tshuaj ntsev. Txhua lub kauj yog muab nrog Daim Ntawv Pov Thawj Kev Xeem Khoom (MTC) thiab daim ntawv tshuaj xyuas.

• Q: Yuav ntim thiab thauj li cas?

  A: Kev ntim khoom: Cov ntawv pov thawj dej tsis muaj dej + steel band khi, lossis ntim ntim raws li cov neeg siv khoom xav tau (xws li rooj ntoo, cov yeeb yaj kiab tsis muaj dej);
  Txoj kev thauj mus los: kev thauj mus los, kev tsheb ciav hlau, kev thauj mus los hauv hiav txwv. Peb tuaj yeem pab hauv kev sib cuag logistics lossis xa khoom raws li kev xa khoom raws li tus neeg siv khoom.
