Mirgina mai zafi (bututun ƙarfe mara sumul) : bututun zagaye billet → dumama → huda → birgima mai birgima uku, birgima mai ci gaba ko fitarwa → cire bututu → girma (ko ragewa) → sanyaya → bututu mara komai → miƙewa → gwajin matsin lamba na ruwa (ko gano lahani) → alama → ajiya.

Zane mai sanyi (na birgima) bututun ƙarfe mara sumul: bututun zagaye billet → dumama → huda → kan → annealing → pickling → mai (rufe jan ƙarfe) → zane mai sanyi mai wucewa da yawa (birgima mai sanyi) → bututu mara komai → maganin zafi → miƙewa → gwajin matsin lamba na ruwa (gano lahani) → alama → ajiya.
