1. Ibikoresho:Icyuma cyagutseabarinzibikozwe muri aluminium, ibyuma bidafite ingese, nanone ibyuma bya galvanis, nibindi.

2. Ingano rusange:

Ubunini bw'umwobo ubusanzwe 3,2 x 5.5mm n'uburemere 0.5 kg / m2 (nyuma yo gushiramo ifu), ubugari bwa mm 500 cyangwa mm 1000, n'uburebure bwa m 50.

Ingano y'urupapuro irashobora kugabanywa ukurikije ibyo abakiriya bakeneye.

Umwobo uzwi cyane ni diyama, nubundi bwoko bwumwobo ni umwobo wa mpandeshatu, umwobo uzengurutse, umwobo wa mpandeshatu, nibindi.

3. Ikoranabuhanga:Igicuruzwa cyarangiye kizahanagurwa kandi kiringanizwe, kandi ingano irashobora kugabanywa no kugororwa uko bishakiye ukurikije ibyo umukiriya asabwa, kugirango net net irusheho kuba myiza kandi ifite ubushobozi bwo gutwara.

4. Ibiranga:Uburemere bworoshye, ubuziranenge, kurwanya ruswa kandi nta ngese, ubuzima burebure

5. Gusaba:Abashinzwe kurinda ibyuma byagutse bikoreshwa cyane muri villa, abaturage ndetse ninyubako zabatuye.Irakoreshwa mukurinda umwanda wawe hejuru yinzu, umwobo, cyangwa umuyoboro wamazi kutarenza urugero, binabuza inyamaswa zimwe na zimwe kujya mu muyoboro, nk'ibisimba, inyoni n'udukoko.
