Amashanyarazini ukurinda kwangirika hejuru yurupapuro rwicyuma no kongera ubuzima bwumurimo.Ubuso bwurupapuro rwicyuma rushyizweho nicyuma cya zinc.Ubu bwoko bwicyuma cya shitingi / coil bita galvanised sheet / coil.Igiceri cyoroshye cyane cyinjijwe mu kigega cya zinc gishongeshejwe, ku buryo igice cya zinc gifatirwa hejuru.Kugeza ubu, ikorwa cyane cyane nuburyo bukomeza bwo gusya, ni ukuvuga kwibiza kwibiza kumpapuro zometse kumatanki hamwe na zinc yashongeshejwe kugirango ikore urupapuro / coil.
Nigute ushobora gutandukanya uburemere bwibyuma?Ibipimo byo kubara ibiro byurupapuro rwerekana:
M (kg / m) = 7,85 * ubugari (m) * ubugari (mm) * 1.03
Kurugero: umubyimba 0.4 * 1200 ubugari: uburemere (kg / m) = 7.85 * 1.2 * 0.4 * 1.03 = 3.88kg / m
Igiceri cya galvanised kigomba kugira isura nziza, kandi ntihakagombye kubaho inenge zangiza imikoreshereze yibicuruzwa, nko kutagira isahani, umwobo, ibice, ibibyimba, umubyimba mwinshi cyane, gushushanya, umwanda wa acide chromic, ingese yera, nibindi. Ibipimo byamahanga ntibisobanutse neza kubijyanye nubusembwa bwihariye.Inenge zimwe zigomba gutondekwa mumasezerano mugihe utumiza.
