1. Okugabanya okusinziira ku bintu .
Ekyuma kya koyilo: Ekika kya koyilo y’ekyuma ekisinga okumanyibwa, ekigabanyizibwa okusinziira ku bintu nga kaboni structural steel coil (nga Q235), wansi-alloy high -Strength steel coil (nga Q355), stainless steel coil (nga 304 ne 316), ne alloy structural steel coil. Okukozesa mulimu okuzimba, ebyuma, n’amakolero g’eddagala.
Aluminiyamu coil: Ekoleddwa mu aluminiyamu alloys (nga 1-series, 3-series, ne 5-series), ebeera nnyangu, egumya okukulukuta, era erina obusobozi obulungi ennyo obw’ebbugumu. Ekozesebwa mu by’omu bbanga, ebitundu by’emmotoka, n’ebintu eby’okwewunda.
Copper coil: Kuno kw’ogatta coil ya kikomo emmyufu ne coil y’ekikomo. Ewa amasannyalaze n’ebbugumu mu ngeri ennungi ennyo era ekozesebwa mu byuma by’amasannyalaze, ebikozesebwa ebituufu, ne payipu.
Koyilo y’ekyuma endala: coil ey’enjawulo, nga titanium coil (waggulu-ebbugumu n’okukulukuta-egumira, ekozesebwa mu by’omu bbanga) ne zinc coil (nga substrate for anti-ebizigo ebikulukuta), ekozesebwa mu nkola eza waggulu-end.
2. Okugabanya nga tuyita mu nkola ya rolling .
Ekika ky’enkola Enkola y’enkola y’okukola Engeri y’okukolamu Enkola z’emirimu Enkozesa .
Hot-rolled coil: steel billets zibuguma okutuuka ku bbugumu erya waggulu (ebiseera ebisinga waggulu wa 1000℃) nga tezinnaba kuyiringisibwa. Enkola eno egaba empalirizo eziyiringisibwa ennyo era esobozesa okukola ebipande ebinene. Ebipande bino biwa obukaluba obw’amaanyi ku ngulu, obugumu obulungi, amaanyi aga wakati, n’omuwendo omutono. Ebipande bino bikozesebwa mu bizimbe ebizimba (nga ebizimbe eby’ekyuma n’ebibanda), ebyuma ebikola ebyuma, ne payipu.
Cold-rolled coil: eyokya-koyilo eyiringisibwa eyiringisibwa ku bbugumu erya bulijjo, ekivaamu obutuufu obusingako n’obusobozi okuyita mu kuyiringisibwa okuwera okugonza. Empapula zino ziwa okumaliriza okw’okungulu okw’amaanyi, obutuufu obw’ekipimo obw’amaanyi (okukyama kw’obugumu obutono), n’amaanyi n’obukaluba okweyongera (okunyweza okuyita mu kuyiringisibwa ennyogovu). Empapula zino zikozesebwa mu bipande by’emmotoka, ebisenge by’ebyuma, ebitundu by’ebyuma ebituufu, n’ebintu eby’okwewunda.
3. Okugabanya okusinziira ku mbeera y’okungulu .
Koyilo esiikiddwa: eyokya-koyilo esimbiddwa mu kkooko okuggyawo minzaani ya okisayidi ey’okungulu, ekivaamu ekifo ekiweweevu ekisaanira okuweta obutereevu oba okuyiringisibwa okw’ennyogoga okuddirira.
Galvanized coil: layeri ya zinki esiigibwa ku ngulu wa koyilo okuyita mu kwokya-Siikiza galvanizing oba electroplating, ekivaamu okuziyiza okukulukuta okulungi ennyo. Koyilo zino zikozesebwa mu kuzimba ebweru, ebisenge by’ebyuma, ne chassis z’emmotoka.
Langi-Koyilo esiigiddwa: Ekizigo kya langi (nga polyester oba fluorocarbon coating) ekissiddwa ku ngulu wa galvanized oba cold-okuyiringisibwa coil. Egatta eby’okwewunda n’okukulukuta-ebiziyiza era ekozesebwa mu kuzimba ebisenge bya kateni, ebisenge by’ebyuma, ebipande, n’okukozesebwa okulala.
uncoated coil: Bare coil nga tewali kulongoosa kungulu, nga-okuyiringisibwa kwa koyilo omuddugavu (n'ekipimo kya oxide) n'ennyonta-okuyiringisibwa kwa koyilo eyakaayakana (smooth, uncoated).
