Zida zopangira (Steel Strip) zokhala ngati koyilo zimamasulidwa ndikuzipanga kukhala gawo lodutsa zida zolowera.Gawo lolowera limathandizira mphero ya chitoliro kuyenda mosalekeza pogwiritsa ntchito zida zolumikizira mizere ndi zida zodziunjikira.Chitoliro chimapangidwa mu mawonekedwe ozungulira ndikudutsa pagulu la zodzigudubuza zoyendetsedwa ndi zopanda pake za gawo lopanga isanayambe kuwotcherera.Mu gawo kuwotcherera chitoliro ndi longitudinally welded ntchito mkulu pafupipafupi induction njira kuwotcherera.Mkanda wakunja umachotsedwa ndikupangidwa ngati zinyalala.Msoko wowotcherera ndi ayironi, ndipo chitoliro chimadutsa mu gawo lozizira.Mu gawo la sizing, chitoliro chimapangidwa kuti chikhale chokhazikika ndikusinthidwa kukhala mawonekedwe odziwika.Pambuyo poyesa, chitoliro chimadulidwa mpaka kutalika kwake pogwiritsira ntchito zida zodulira zowuluka ndikuzipereka muzotengera zomwe zimadutsa mumayendedwe othamanga.
