  - Cov khoom lag luam: Txhawb 20+ cov qauv thoob ntiaj teb (JIS, GB, DIN, thiab lwm yam)
  

• 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: Koj puas tuaj yeem muab kev cai qhov ntev lossis txheej txheej?

  kiag li. Peb muab Deep Customization Services:
  - Qhov Loj: Dav 200-2,000mm, Thickness 0.3-25mm

  - 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: 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 kev lag luam twg yog cov khoom tsim nyog rau?
  Koj puas tuaj yeem muab cov kev daws teeb meem tshwj xeeb hauv kev lag luam?

  A: Lawv tau siv dav hauv tsheb (lub cev qhov chaw, lub log rims), cov khoom siv (HVAC, tub yees), ntim khoom (khoom noj khoom haus, cov thawv ntim aerosol), thiab cov cuab yeej siv (racking, cov cuab yeej ua liaj ua teb). Peb optimize coatings rau kev lag luam tshwj xeeb cov kev xav tau.

• 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 lus qhia tshwj xeeb ntau npaum li cas?

  A: Thickness: 1.5mm txog 20mm (kho tau raws li cov kab ntau lawm)
  Dav: 600mm - 2200mm (qhov tsawg kawg nkaus / qhov ntev yuav tsum tau cim)
  Sab hauv txoj kab uas hla: Φ610mm (feem ntau) los yog Φ508mm (thov paub meej tias lub tuam txhab cov kab ntau lawm)
  Sab nraud txoj kab uas hla: txiav txim los ntawm qhov hnyav yob, feem ntau ≤2500mm

• 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: Ntev npaum li cas lub txee lub neej ntawm cov khoom?

  A: Nyob rau hauv ib txwm cia tej yam kev mob (qhuav, zoo-ventilated thiab tsis-corrosive ib puag ncig), lub txee lub neej yog 12 lub hlis (los ntawm hnub tsim).

• Q: Koj puas tuaj yeem muab kev qhia?

  A: Peb tuaj yeem muab cov lus qhia ua haujlwm rau kub-kuav los tiag steel coils (xws li kev txiav thiab vuam), daim ntawv thov kev daws teeb meem, lossis npaj kev txhawb nqa ntawm cov engineers (yuav tsum tau teem caij ua ntej).
