Imikorere ya girder ikora ifite ibyiza-byuzuye, imiterere yoroshye, gusubira inyuma, byoroshye-demoulding nibikorwa byoroshye. Irashobora kuzamurwa cyangwa gukururwa kurubuga rwa interineti, hanyuma ikamanurwa muburyo bumwe cyangwa ibice nyuma ya beto igera ku mbaraga, hanyuma igakuramo ifumbire yimbere kuva mukenyero. Nibyoroshye gushiraho no gukemura, imbaraga nke zumurimo, kandi neza.
Ikiraro cya kiraro kigabanyijemo ibice bito, byateguwe muburyo bwiza bwo kugenzura ibibuga byiza, hanyuma, bigashyirwaho kugirango bishyirwemo nibikoresho byiza byo kubaka.
