Binyuze mu ishami ry'umukara ritunganya amasasu (C2D) ririmo umunyu wa feza cyangwa umunyu wumuringa, filime yirabura ikorwa hamwe nubwinshi bwa 10-15μm. Igiciro kiri hejuru ariko isura irihariye.

Koresha Pastivetion ya Zinc (C2C), Gutwika Ububintu 8-15μm, Ikizamini cyumunyu gishobora kugera kumasaha arenga 72, isura y'amabara, isura nziza yo kurwanya ruswa.

GB / T 882-2008 "PIN" isanzwe, izina rya diameter 3-100mm, ibikoresho birimo ibyuma bya karubone, ibyuma bidafite ishingiro, nibindi, bijyanye na C1B cyangwa C1Apos nyuma yo kuvura.

Ibara rya zinc passivation (c2C) ryemejwe, uburebure bwa coating ni 8-15 mm, kandi kurwanya ruswa yo kwipimisha umunyu ni amasaha arenga 72, bifite ibikorwa byo kurwanya ruswa no gushushanya.

Igizwe na Bolts, imiyoboro yo kwaguka, gutakaza neza, gutakaza amasoko na hexagonal. Ibikoresho ahanini ni ibyuma bya karubone (nka Q235), hamwe nubunini bwa elegisrogvane urwego ni 5-12μm, buhura nubuziranenge.

Umukororombya ChromaT Passivetion (C2C) bikorwa hashingiwe kuri elegitalvanizing kugirango ikore film ifishi ifite ubunini bwa 8-15μm. Ikizamini cyumunyu kirashobora kumara amasaha arenga 72 nta rujya.

Bikozwe muri Q235 ibyuma bya karubone nibindi bikoresho, ubuso bwa electro-sulectness, hamwe nubunini bwa cootes ni 5-12μm) cyangwa c1i (blan zinc) muri GB / T 13911-92.
