Hariho uburyo bubiri busanzwe bwo gutondekanya rebar: bumwe bushingiye kumiterere ya geometrike, yashyizwe mubice cyangwa igabanijwe ukurikije imiterere itandukanye yambukiranya imipaka hamwe nimbavu.Kurugero, mubwongereza Standard (BS4449), rebar igabanijwe mubwoko bwa I n'ubwoko bwa II.Iri tondekanya ryerekana cyane cyane imikorere yo gufata ibyuma byahinduwe.Icya kabiri, ukurikije ibyiciro byerekana (amanota), kurugero, mubuyobozi bukuru bwigihugu cyacu, rebar ni (G B1499.2-2007) naho inkoni y'insinga ni 1499.1-2008), rebar igabanijwemo bitatu amanota ukurikije urwego rwimbaraga (umusaruro point / tensile strength);Ukurikije inganda z’Ubuyapani (JI SG3112), rebar igabanijwemo ibyiciro bitanu ukurikije imitungo yuzuye;Igipimo cy’Ubwongereza (BS4461) nacyo kigaragaza amanota menshi yikizamini cyo gukora kububiko bwibyuma byahinduwe.Byongeye kandi, rebar irashobora kandi gushyirwa mubikorwa ukurikije intego zayo, nka rebar isanzwe ya beto yubakishijwe ibyuma hamwe nubushyuhe bukoreshwa nubushyuhe bwa beto yubahwa.
Ibyuma byahinduwe bigabanijemo ibice bisanzwe bishyushye bizengurutswe nibyuma bishyushye neza.Ukurikije ibisobanuro bisanzwe, ibyuma bisanzwe bishyushye bizengurutswe nibyuma bitangwa muburyo bushyushye.Imiterere ya metallografiya igizwe ahanini na ferrite na pearlite, kandi ntayindi miterere izagira ingaruka kumikorere ya serivisi.Icyuma gishyushye neza-cyuma cyerekana ibyuma byerekana neza ibyuma byakozwe muburyo bwo gukonjesha no kugenzura gukonjesha mugihe cyo gushyushya.Imiterere yacyo ya metallografiya igizwe ahanini na ferrite na pearlite, kandi ntayindi miterere izagira ingaruka kumikorere ya serivisi, kandi ingano yintete ntishobora kuba mike kurenza icyiciro cya 9.
Urwego rwibisanzwe rushyushye ruzengurutse urubavu rugizwe na HRB, agaciro karanga imbaraga zumusaruro hamwe nikimenyetso cyo kurwanya imitingito (+ E);Urwego rwimbuto nziza zishyushye zometseho urubavu rugizwe na HRBF, agaciro karanga imbaraga zumusaruro hamwe nikimenyetso cyo kurwanya imitingito (+ E);F ni inyuguti yambere ya Cyiza.Ibyiciro bisanzwe bishyushye bizunguruka bigabanijwemo ibyiciro bitanu: HRB400, HRB500, HRB600, HRB400E na HRB500E;Amanota yimbuto nziza zishyushye zuzuyemo ibyuma bigabanijwemo HRBF400, HRBF500, HRBF400E na HRBF500E.
Ibyuma bifata umugozi bikoreshwa cyane mubwubatsi bwububatsi nkamazu, ibiraro n'imihanda.Kuva mu mihanda minini, gari ya moshi, ibiraro, imigezi, tunel, kurwanya umwuzure, ingomero n’ibindi bigo rusange, kugeza ku rufatiro, ibiti, inkingi, inkuta, amasahani, hamwe n’inyubako n’inyubako ni ibikoresho byubaka.Kugeza ubu, ibyuma bya HRB400 cyangwa HRB400E byakoreshejwe cyane ku isi.Isosiyete yacu irashobora gutunganya HRB500, HRB600 nizindi mbaraga zikomeye zahinduwe ibyuma.
Ibipimo bya rebar isosiyete yacu irashobora gutanga
