Ibisobanuro
Byongeye kandi, ibikoresho bya PVC birwanya cyane ubushyuhe bukabije, bigatuma bikoreshwa umwaka wose. Yaba ari icyi gishyushye cyangwa imbeho ikonje, iyi mishumi ntacyo itwaye, igumana imbaraga n'imikorere mugihe. Iyi elastique ni ngombwa cyane cyane kuko yemeza ko umukandara uzakora umurimo wacyo wizewe uko ibidukikije byifashe kose. Gukoresha igishushanyo mbonera cyongera imikorere n'imikorere yiyi mishumi. Amapfizi yakozwe kugirango afate umukandara neza kuri corbel kugirango umukandara uhagarare ndetse no mugihe cyo kugenda kwinyamaswa. Ibi bigabanya ibyago byo kunyerera cyangwa kugwa, gukumira impanuka zishobora kubaho cyangwa kubangamira inyamaswa nabahinzi.
Ikindi kintu kigaragara kiranga ibi birenge byamaguru ni ukongera gukoreshwa. Imishumi irashobora gukurwaho byoroshye mugihe inka zimaze gukura cyangwa zitagikenewe, kandi igishushanyo mbonera cyorohereza iki gikorwa. Byongeye kandi, imishumi irashobora guhindurwa mukurekura cyangwa gukomeretsa indobo, bigatuma ushobora kwihindura ubunini bwinka kandi neza. Iyi marike y'ibirenge ikozwe mubikoresho bya PVC itanga igihe kirekire, irwanya ubushyuhe hamwe nigisubizo cyinshuti kubakoresha gucunga inka. Ubwitonzi bwabo no kurwanya kumeneka byemeza kuramba, bakemeza ko bashobora kwihanganira ibikorwa byinka. Igishushanyo mbonera cyerekana neza umutekano mugihe byoroshye gukoresha no guhinduka. Hamwe nizo nyungu, abahinzi barashobora gukoresha neza iyo mishumi kugirango banoze imikorere yinka zabo no gukora neza muri rusange.
