Icuma gikonjeshwa, kizwi kandi nka coil y'icyuma. Icuma gikonjeshwa hakoreshejwe gukanda no gukanda bikonjeshwa. Kugira ngo byorohereze kubika no gutwara no gutunganya ibintu bitandukanye. Icuma gikonjeshwa ahanini ni coil ishyushye izunguruka n'icumba gikonjeshwa. Icuma gikonjeshwa ni ikintu gitunganywa mbere yo kongera gukoresha billet. Icuma gikonjeshwa ni cyo gitunganywa nyuma ya coil ishyushye izunguruka. Uruganda rwacu rukora cyane cyane kandi rugakora coil ishyushye izunguruka. Icuma gikonjeshwa n'icumba gikonjeshwa n'amabara menshi kandi abakiriya bacu ba koperative muri rusange batumiza coil y'icyuma ifite uburemere bwa toni 25-27. Ubushobozi bwo gukora coil ishyushye mu Bushinwa bukomeje kwaguka, hari imirongo myinshi ikora coil ishyushye, kandi hari imishinga imwe n'imwe iri hafi kubakwa cyangwa gutangira gukora. Urugero, tugurisha coil y'icyuma ya dx51d Z100 galvanized.

Umuzingo wo gusiga irangi ni umusaruro ushingiye ku isahani ishyushye ya galvanized, isahani ya zinc ya aluminiyumu ishyushye n'isahani ya electro galvanized. Nyuma yo gutunganya ubuso mbere (gukuraho amavuta no guhindura imiti), urwego rumwe cyangwa nyinshi z'imyenda ya organic zishyirwa ku buso, hanyuma zikatekeshwa zigakomera. Yitiriwe icyuma gitwikiriwe n'amabara atandukanye y'imyenda ya organic, byitwa color coated coil mu magambo ahinnye. Uretse kurinda urwego rwa zinc, organic coat iri ku urwego rwa zinc igira uruhare mu gutwikira no kurinda icyuma gitwikiriwe n'umuzingo w'icyuma gishyushye nk'ibikoresho by'ibanze, kugira ngo wirinde ko icyuma cyangirika. Igihe cyo gukora ni kinini inshuro 1.5 kuruta icyuma gitwikiriwe. Umuzingo wo gusiga irangi ufite uburemere bworoshye, isura nziza kandi urwanya ingese, kandi ushobora gutunganywa mu buryo butaziguye. Ibara muri rusange rigabanyijemo umweru w'ikijuju, ubururu bw'inyanja n'umutuku w'amatafari. Rikoreshwa cyane cyane mu nganda zamamaza, mu nganda z'ubwubatsi, mu nganda z'ibikoresho byo mu rugo, mu nganda z'amashanyarazi, mu nganda zo mu nzu no mu nganda z'ubwikorezi.

Igipfundikizo gikoreshwa mu gusiga ibara kigomba guhitamo resin ikwiye hakurikijwe imiterere itandukanye ikoreshwa, nka polyester yahinduwe na silicon, polyvinyl chloride plastike sol, polyvinylidene chloride, nibindi. Abakoresha bashobora guhitamo bakurikije icyo igenewe.
