Muri iki gihe cya none, hari ibyiza byinshi byo gukoresha imiyoboro yubakishijwe ibyuma mu mishinga yubwubatsi, nko kubungabunga ibidukikije, amafaranga y’ubwishingizi buke, gushushanya neza kimwe no kongera gukoreshwa. Nyamara mu ngero nyinshi, ibimenyetso byo kunanirwa kw'imiyoboro yegereje byagaragaye amezi cyangwa imyaka, kandi ntibyirengagijwe. Iyo ibyuma byubatswe na ruswa, biba bidafite umutekano kandi birashoboka cyane ko bitera impanuka, nko gusenyuka.
Ahanini, birasabwa cyane ko abakoresha bagomba kugerageza kugira isuku yizengurutse imiyoboro, kandi bakagerageza kwirinda gushyira imiyoboro hamwe nibintu bikarishye hamwe, kugirango birinde kwangirika bitari ngombwa kumubiri wimyanda no kwambara ibikoresho byo hejuru. Mugutunganya imiyoboro, abakora imiyoboro yicyuma bazakora uburyo bwihariye bwo kuvura imiyoboro nkuko abakiriya babisabwa. Irangi risize irangi ni inzitizi yo gukumira ihererekanyabubasha ry’amashanyarazi kuva igisubizo cyangirika ku cyuma munsi. Mu buryo bumwe, bisa nkibikenewe cyane kugirango uhitemo icyuma gikingira gikingira imiyoboro yicyuma ukurikije ibisabwa byihariye bya porogaramu. Muri iyi myaka, hariho imyiteguro myinshi itandukanye yo gutunganya imiyoboro yicyuma igomba gukoreshwa bitewe nibisabwa byihariye mubikorwa bifatika mubuzima. Kurugero, imiyoboro yicyuma yakoreshejwe kumiyoboro ikonje ikonje mumyaka mirongo kugirango yongere kuramba no kuba inyangamugayo kimwe no kugabanya amafaranga yo kubungabunga. Mubyongeyeho, hari izindi nama nkeya zo kurinda umuyoboro wibyuma kwirinda ruswa muri serivisi, urugero nko gusiga amavuta cyangwa amavuta yabitswe hejuru yicyuma.
Ikigeretse kuri ibyo, kwita cyane ku miyoboro y'icyuma ikoreshwa kandi imirimo imwe n'imwe yo kuyitaho nayo irakenewe. Nkuko ibyuma nicyuma byoroshye mubidukikije, icyamamare kuri bo ni ukurinda ruswa binyuze muri "galvanizing". Imiyoboro yicyuma kibanziriza icyuma hamwe nicyuma gishyushye gishyizwe hamwe nubwoko bubiri busanzwe bwumuyoboro wicyuma mumasoko yicyuma. Ipitingi irinda ni ikwirakwizwa rya zinc na fer kandi bizamara imyaka myinshi. Gushyushya ibishishwa bishyushye bigomba kubaho nyuma yibicuruzwa bimaze guhimbwa, kugirango impande zose zibikoresho zirindwe na galvanic. Uretse ibyo, kubijyanye no kuvura amarangi kugirango birinde ruswa, hejuru yumubiri wibyuma hasukurwa hanyuma ugasiga irangi ryirabura. Ibicuruzwa bisize irangi birashobora kuba byiza kandi irangi ritanga uburinzi bwikirere. Nyamara, isura irangi ntishobora kuba ihitamo ryiza kumihanda minini, nkuko irangi rishobora kwambara, ryerekana ibyuma munsi. Niba ushaka ibicuruzwa bishushanyije umukara, vuga ibi mumasanduku y'ibitekerezo mugihe cyo gusaba.
