1. Ubwoko butandukanye bwo korora urukwavu, ubworozi bw'urukwavu rw'umugabo, ubworozi bw'inkwavu.
Uruhinja rw'urukwavu na nyina urukwavu rukingira gusa ariko ntirutandukane.
Irashobora guteza imbere imikurire y'urukwavu.2.Guhumeka neza birashobora kwirinda indwara zanduza neza.
Irashobora kongera igipimo cyo kubaho k'urukwavu rw'ibicuruzwa.
Dushushanya kugabanura ikibaho cyo kunyerera umwanda hasi.
3. Kugirango isuku yinkwavu isukure nisuku, urashobora gukoresha umukandara wimyanda cyangwa umwanda kugirango usukure umwanda.
4. Ibikoresho bito: ibyuma byoroheje byoroheje byoroshye, insinga ya galvanis, insinga zidafite ingese.
Urupapuro rwa Galvanised, aluminium –zinc urupapuro rwicyuma.5. Kuvura hejuru: gushyushya galvanise.Imurambararo ya net net imbere hamwe nicyuma cyuruhande rwicyuma: 3mm.
