Simbi chimirochivakwa chinoumbwa nesimbi uye ndeimwe yemhando huru dzekuvaka. Chimiro chacho chinonyanya kuumbwa nematanda esimbi, mbiru dzesimbi, simbi dzesimbi uye zvimwe zvinhu zvakagadzirwa nechikamu chesimbi uye mahwendefa esimbi, uye inotora silanization, yakachena manganese phosphating, kugeza uye kuomesa, galvanizing uye mamwe maitiro ekudzivirira ngura. Izvo zvikamu kana zvikamu zvinowanzobatanidzwa ne welds, bolts kana rivets. Nekuda kwehuremu hwayo huremu uye kuvakwa kuri nyore, inoshandiswa zvakanyanya mumafekitori makuru, nzvimbo, zvivakwa zvepamusoro-soro, mabhiriji nemimwe minda. Chimiro chesimbi chiri nyore kuita ngura, iyo yakajairika simbi chimiro kubvisa ngura, galvanized kana pendi, uye kugadzirisa nguva dzose.
