Pakati pemapeji epakati ezana ramakore rechigumi nemapfumbamwe, kutama kwekurima muUnited States kwakaona varimi vazhinji vachitanga kubvisa nzvimbo isina chinhu, vachienda kumadokero kumapani uye kumaodzanyemba kwakadziva kumadokero, zvichiteerana. Sezvo zvekurima zvakatama, varimi vakawedzera kuziva nezvekuchinja kwemamiriro ekunze, izvo zvakaratidza kuchinja zvishoma nezvishoma kubva kumasango edunhu rekumabvazuva kuenda kunzvimbo yakaoma yeuswa hwekumadokero. Musiyano wetembiricha nenzvimbo yakatungamira kune zvidyarwa zvakasiyana kwazvo uye maitiro munzvimbo mbiri idzi. Nyika isati yacheneswa, yakanga ine matombo uye isina mvura. Pakatanga kurima, kushaikwa kwezvishandiso zvekurima zvakagadziridzwa munharaunda zvaireva kuti nzvimbo zhinji yakanga isina vanhu uye isina kutorwa. Kuti vajairane nemhoteredzo itsva yekudyara, varimi vazhinji vakatanga kugadzira fenzi dzewaya dzine minzwa munzvimbo dzavairima.
Nekuda kwekutama kubva kumabvazuva kuenda kumadokero, kune huwandu hukuru hwevanhu kuti vape zvigadzirwa, nekutanga kumabvazuva vakavaka madziro ematombo, munzira yekutamira kumadokero uye vakawana miti mirefu yakareba, fenzi yemapuranga uye kubva kune yakasvibirira. zvinhu munzvimbo iyi zvishoma nezvishoma akawedzera kusvika kumaodzanyemba, panguva iyoyo zvakachipa basa uye regai kuvaka kuva nyore chaizvo, asi kumadokero chikamu nokuda ibwe uye miti haina zvakawanda kudaro, fenzi haana saka vakawanda akamisa. Asi nechekumavirira, uko matombo nemiti zvakanga zvisina kuwanda, kuvharira fenzi kwakanga kusingawanzoitwa.
Mumazuva ekutanga ekugadzirisa nyika, nekuda kwekushaikwa kwezvinhu, pfungwa dzevanhu dzechinyakare dzefenzi dzinogona kuita basa rekudzivirira mumiganhu yavo kubva kune mamwe masimba ekunze kuparadza uye kutsikwa nemhuka, saka pfungwa yekudzivirira yakasimba kwazvo.
Nekuda kwekushaikwa kwematanda nematombo, vanhu vakatanga kutsvaga dzimwe nzira dzekuchengetedza zvirimwa zvavo kunze kwefenzi. Mukutanga kwema1860’s nema1870’s, vanhu vakatanga kurima zvirimwa zvine minzwa nokuda kwefence, asi nekubudirira kuduku nokuda kwokushomeka kwemiti yacho, mutengo wayo mukuru, uye kusagadzikana kwekuvaka fenzi, zvakasiiwa. Kushaikwa kwefence kwakaita kuti basa rekubvisa ivhu rishaye basa. Yakanga isiri kusvika 1873 apo chidzidzo chitsva chakashandura dambudziko ravo apo DeKalb, Illinois, yakagadzira kushandiswa kwewaya ine minzwa kuchengetedza nyika yavo. Kubva panguva ino zvichienda mberi, waya yebarbed ichangopinda munhoroondo yeindasitiri.
Kugadzira nzira uye tekinoroji.
KuChina, mafekitori mazhinji anogadzira waya ine minzwa anoshandisa galvanized wire kana plastiki coated wire yakananga muwaya ine minzwa. Iyi nzira yekurukwa nekumonyorora waya ine minzwa inowedzera kubudirira kwekugadzira, asi dzimwe nguva ine dhizaini yekuti tambo ine minzwa haina kugadzikwa zvakakwana. Nekuvandudzwa kwemichina, ikozvino kune vamwe vanogadzira vakatanga kushandisa kuwedzera kweimwe crimping process, kuitira kuti waya wepamusoro usave wakapoteredzwa zvachose, izvo zvinovandudza zvakanyanya kudzikamiswa kwetambo yebarbed.
