Ga muhimman abubuwan da ke bayyana ingancin sarkar ɗagawa ta duniya.
1. Tushen: Zaɓin Kayan Karfe
Tafiyar zuwa ga sarkar ɗagawa mai aminci ba ta fara a masana'anta ba, amma a injin niƙa ƙarfe. Sarkokin G80 da G100 suna buƙatar ƙarfe na musamman na ƙarfe—yawanci suna ɗauke da abubuwa kamar chromium, molybdenum, da boron.
- Sarƙoƙi na G80:Ana buƙatar ƙarfe mai laushi, mai ƙarancin ƙarfe wanda ke amsawa da kyau ga maganin zafi, misali, 20Mn2 ko 22MnCrNi

5. Kammalawar Sama: Kariya da Aiki
Mataki na ƙarshe shine kariya. Muhalli yana ƙayyade ƙarshen:
- Baƙin Oxide / Mai: Kammalawa ta yau da kullun. Yana ba da matakin tushe na juriya ga tsatsa don amfani a cikin gida kuma yana ba da damar duba sarkar cikin sauƙi don ganin tsagewa.
- Zane (misali, Lambar Launi Mai Kyau): Sau da yawa ana amfani da shi don ganowa (misali,G80 sau da yawa baƙar fata ne, G100 sau da yawa shuɗi ne). Yana bayar da matsakaicin kariya daga tsatsa.
- Galvanizing: Yana ba da kyakkyawan juriya ga tsatsa ga muhallin ruwa ko sinadarai. Duk da haka, wannan yana buƙatar taka tsantsan sosai. Idan ba a yi shi daidai ba (misali, tsinken acid), galvanizing na iya haifar da tarkacen hydrogen, wanda ke sa sarkar mai ƙarfi ta yi rauni sosai. Tsarin musamman bayan yin burodi dole ne. Don kammala Galvanizing Mai Zafi, za a rage iyakar nauyin aiki na sarkar da ƙarfin karyewa da kashi 20-25%.
- Rufin E-Coating (Baya ga Electrophoretic Deposition): Wani zaɓi ne da ake ƙara samun shahara a cikin sarƙoƙin G100. Yana samar da rufin da ya dace, mai ɗorewa, kuma mai jure tsatsa ba tare da haɗarin ruɓewar hydrogen da ke da alaƙa da galvanization mai zafi ba.
Ga ƙwararrun masu yin kayan aiki, sarka kayan aiki ne na aminci. A SCIC, mun yi imanin cewa ana samun aminci ta hanyar kulawa sosai ga kowane ɓangaren samarwa: ƙarfe, walda, maganin zafi, da gwaji.
