Kuzizira kozungulira kozungulira magiredi a SPCC, SPCCT, SPCD, SPCE, SPCF, SPCG
Cold rolled steel sheets & coils grade SPCC ndi Japanese steel grade, from JIS G3141. Dzina lokhazikika: wamba & wamba ntchito ozizira adagulung'undisa mpweya zitsulo pepala ndi Mzere. Gulu lomwelo m'makalasi okhazikika ndi SPCD, SPCE, SPCF, SPCG.

Ntchito:
SPCC/SPCCT: Kugwiritsa Ntchito Wamba & General; Makhalidwe: Oyenera kupindika ndikuwongolera mozama mozama, ndiye mitundu yofunikira kwambiri; Ntchito: Firiji, njanji, switchboards, madengu chitsulo ndi zina zotero.
SPCD: Kugwiritsa Ntchito Kujambula & Kusindikiza; Makhalidwe: Chachiwiri kwa SPCE, ndi khalidwe la kupatuka kwakung'ono kwa mbale yachitsulo yojambula; Mapulogalamu: Chassis yamagalimoto, denga ndi zina zotero.
SPCE/SPCF: Kugwiritsa Ntchito Zojambula Zakuya & Kupondaponda; Makhalidwe: Mbewu imasinthidwa, kujambula kozama kumakhala kwabwino kwambiri, kupondaponda kumatha kukhala kokongola. Mapulogalamu: Chophimba galimoto, mapanelo akumbuyo ndi zina zotero.
SPCG: Zojambula Zakuya & Kupondaponda & Kugwiritsa Ntchito Khomo; Makhalidwe: Chitsulo chochepa kwambiri cha carbon chozizira, chojambula bwino kwambiri. Mapulogalamu: bolodi lamkati lagalimoto, pamwamba ndi zina zotero.
Ndemanga: SPCCT ndi ogwiritsa ntchito kalasi ya SPCC yomwe imayenera kuwonetsetsa kuti kulimba ndi kufalikira kwa mitunduyo. SPCF, SPCG iyenera kuwonetsetsa kuti pali kusakalamba (osati chifukwa cha kugwedezeka kwa katundu), pambuyo pa fakitale kunja kwa miyezi 6 - ndiko kuti, SPCC, SPCD, SPCE ngati yasungidwa kwa nthawi yaitali, kupanga kusintha makina ntchito, makamaka kuchepetsa ozizira chidindo ntchito, ayenera kugwiritsidwa ntchito posachedwapa.
Mndandanda wa mndandanda wa SPCC uyenera kukonzekeretsa kuuma ndi kumtunda pasadakhale poyitanitsa.

Pamwamba:
FB: Kumaliza kwapamwamba: Simakhudza mawonekedwe ndi ❖ kuyanika, zopindika zomatira zomata, monga thovu laling'ono, zokopa zazing'ono, mpukutu waung'ono, zokanda pang'ono ndi utoto wa okosijeni wololedwa kukhalapo.
FC: kutsirizitsa kwapamwamba pamwamba: Mbali yabwino ya mbale yachitsulo iyenera kukhala yowonjezereka kwa chilema, palibe zolakwika zoonekeratu, mbali inayo iyenera kukwaniritsa zofunikira za FB.
FD: Kutsirizitsa kwapamwamba kwapamwamba: Mbali yabwino ya mbale yachitsulo iyenera kukhala yocheperapo pazowonongeka, ndiye kuti, sizimakhudza maonekedwe a utoto kapena pambuyo pa plating khalidwe, mbali inayo iyenera kukwaniritsa zofunikira za FB.
