Igicu gikonje gikonje (Coldroll), gikunze gukoreshwa munganda zibyuma, gitandukanye nigishishwa gishyushye.
Bivuga kuzunguruka mu bunini butaziguye hamwe n'umuzingo ku bushyuhe bw'icyumba hanyuma ukazunguruka mu muzingo wose hamwe n'umuyaga
umukandara w'icyuma. Ugereranije nudupapuro dushyushye, ibishishwa bikonje bifite ubuso bworoshye kandi birangiye, ariko bizashoboka
Imyitwarire myinshi yimbere irabyara, kandi kuvura annealing akenshi bikorwa nyuma yo gukonja.

Ibishishwa by'ibyuma bya galvanizasi (ibishishwa by'ibyuma bya Galvanised), galvanised bivuga ibyuma, ibivanze cyangwa ubuso bwibindi bikoresho bishyizwe hamwe na zinc kugirango bikine uruhare rwiza, rutagira ingese nubundi buhanga bwo kuvura hejuru. Noneho uburyo nyamukuru ni hot-dip galvanizing.
