Ibikoresho bibiri (ibikoresho by'impande z'iburyo)Byabaye ibice by'ingenzi by'imiterere y'urukuta rugoye bitewe n'ubushobozi bwarwo bwo guhuza mu cyerekezo kinini.igifunga gishya cy'ibikumwe bibiriyujuje ibisabwa na EN74 Class B na BS1139, ikoresha igishushanyo mbonera cy’umurambararo wa 48.3mm, gishobora kugera ku muyoboro ugororotse wa 90° hagati y’umurongo utambitse n’inkingi ihagaze kandi gishobora guhindurwa ku mfuruka iyo ari yo yose. Ni nshya kandi igezweho.agapfunyika gafite imigozi ibiriImiterere igenzura amakosa ari muri 0.2mm binyuze mu ikoranabuhanga ryo gucura neza, kandi hifashishijwe amakuru ya BIM mbere yo guteranya, yongera uburyo ibice bishyirwa mu bwubatsi byakozwe mbere ho 60%.

Mu mushinga w’inganda zikora imiti ikomoka ku binyabutabire mu majyepfo y’uburasirazuba bwa Aziya,igifunga cy'ibice bibiriyagaragaje ubushobozi bukomeye bwo guhangana n’ibidukikije: gukomera kwayo kwagumye hejuru ya 80J kuri -40 ℃, birenga cyane impuzandengo y’inganda ya 30J ku bice bisanzwe; Imiterere y’ibikoresho byo gushyiraho ibikoresho byifashishwa mu buryo bwo guhuza byakubye kabiri ubushobozi bwo gushyiraho, kandi itsinda ry’abantu 10 rishobora kurangiza imirimo 300 yo kubaka ikigo mu munsi umwe. Uburyo bwo gutunganya ubuso bushyushye butuma ubuzima bumara imyaka irenga 10 mu bushyuhe bwinshi n’ubushuhe bwinshi, burenze 60% ugereranyije n’ibikoresho bisanzwe byo gufunga.
