eTianjinYuantai DerunIsikwere seqela kunye noxande weldedimibhobho yentsimbibawongwa ngesiqinisekiso semveliso ye-AAAA liziko loCwangciso loShishino lweMetallurgical
Ngokweemfuno ezithile "zokuqinisekisa ngokuqinisekileyo" kwimibhobho edityanisiweyo yesikwere kunye noxande ngeenjongo zolwakhiwo, imibhobho yentsimbi yesikwere kunye noxande ngeenjongo zolwakhiwo jikelele, umgangatho uqwalasela ngokubanzi ukuguquguquka komgangatho, ingxelo esemgangathweni, isiqinisekiso semveliso, amabhaso embeko kwinqanaba lemveliso. , isakhono sokuqinisekisa umgangatho kumgangatho weshishini, isakhono sokwenza izinto ezintsha, imfezeko yeshishini, inqanaba lenkonzo, inqanaba lolwazi kunye nezinye iziqulatho. Ukugxila ekuhanjisweni komgangatho wemveliso yeshishini isakhono kunye nexabiso lophawu lwemveliso, ukuphuhlisa imigangatho yovavanyo lwenzululwazi, olufanelekileyo, oluphambili kunye olusebenzayo, ukubonelela ngesiseko senqanaba elilandelayo lenjongo yolwakhiwo umbhobho odityanisiweyo, injongo ngokubanzi epholileyo eqengqelekayo okanye eshushu eqengqelekayo edityanisiweyo yombhobho wentsimbi uqinisekisiweyo. isiqinisekiso sohlobo, ukulima kunye nokwakha iimveliso zentsimbi "i-brand eqinisekisiweyo".
