  - Txheej: Precision-tswj zinc (20–275 g / m²) lossis tin (1.1–11.2 g / m²) txheej
  - Nto tiav: 10+ kev xaiv (matt, iav, embossed, thiab lwm yam)
  - Daim ntawv qhia ua tau xa tuaj hauv 48 teev rau kev thov kev cai
  

• 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.

• Q: 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 ua li cas tiv thaiv corrosion / hnav tsis kam?

  A: Kev tiv thaiv corrosion yog txhim kho los ntawm kev tsim cov hlau alloy (xws li Zn-Ni, Fe-Zn txheej), porosity tswj (

• 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: 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: Cov txheej txheem tsim khoom puas yog ib puag ncig tus phooj ywg?
  Cov coatings puas tuaj yeem siv dua?

  A: Peb siv chromium-dawb passivation, halogen-free kev kho mob, thiab lwm yam eco-friendly txheej txheem (raws li RoHS, ELV). Cov coatings yog 100% recyclable ntawm electrolytic stripping (xws li, tinplate detinning).

• 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 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: 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.
