1. Kwinjira cyane, ntabwo byoroshye kugwa.
2. 2mm yibyibushye, birakomeye.
3. Gukomera byuzuye, ntabwo byoroshye kumeneka.
4. Ubuso bushyushye-dip galvanised, ntabwo byoroshye kubora.
Imisumari irwanya umuriro ifite imisumari idasanzwe igizwe nisahani izengurutse hamwe na sitidiyo ifatanye. Iyi miterere ituma imisumari yumuriro yoroha cyane kandi ihamye mukoresha. Byongeye kandi, ibikoresho bidasanzwe byibyuma byo mu bushyuhe bwo hejuru nabyo bituma pin irwanya umuriro igira ibiranga kurwanya ruswa no kurwanya okiside, ishobora gukoreshwa igihe kirekire ahantu h’ubushuhe cyangwa ivumbi bitarangiritse byoroshye. Byongeye kandi, umusumari wumuriro urashobora kandi gukumira kugenda ku mpanuka cyangwa kunyeganyega ibikoresho. Byongeye kandi, kwishyiriraho iyi yihuta biroroshye cyane. Ukeneye gusa gushyira munsi yumusumari kumwobo washyizwemo ibikoresho byumuriro, hanyuma ugakanda ushikamye, umusumari uzahita winjizwa mumwobo hanyuma ugashyirwaho.
1. Isahani yibyuma, uburebure bwa 2mm, diameter 21mm, gutwika zinc ntabwo biri munsi ya 5μ.
Iyo urasa C30-C40 beto, ubushobozi bwo gushushanya muri 4200-5800N
2. Ubukomezi butandukanye bwa beto bugira ingaruka kuburebure butandukanye bwimisumari ya pipe iganisha kumakuru atandukanye. Dukoresha urwego rwumutekano rwamakuru. Mubisanzwe, gushushanya imbaraga zumusumari umwe wumutwaro uri munsi ya 100kg.
Amatara yumuriro akoreshwa cyane mubihe byinshi, nkicyuma cyoroshye, icyuma cyikiraro, amashanyarazi, kurwanya umuriro, imitako yinzu, inzugi nidirishya, gukurikirana, kwamamaza nibindi.
Kabiri shingiro, ifite umutekano kuruta umwe cyangwa ibyo bita moteri nyinshi. Igice cy'ingufu z'umusumari wahurijwe hamwe gikozwe muri pamba ya nitro na nitroglycerine cyangwa ibindi bikoresho bya pulasitiki biturika nkibikoresho byibanze byingufu. Mubisanzwe bikoreshwa mubibunda binini bya kalibiri hamwe na minisiteri yo kurasa.
