Karatasi ya Chuma Iliyoviringishwa ya ST12 Baridi

Chuma kilichovingirwa baridi ni bidhaa zetu za kawaida na zinazotumiwa kwa kawaida baridi. Chapa yake inaweza kugawanywa kwa ujumla kuwa: ST12, ST13, ST14, ST15, ST16 na kadhalika.


ST12 ni kiwango cha Kijerumani (DIN1623), Ni chuma cha kawaida kilichoviringishwa baridi. Kimsingi, ST12 inaweza tu kuinama na kuunda, na hakuna stamping inaruhusiwa.


Ubora wa uso: FC, FB
