Kuva yashingwa mu 2014, Botop Steel yabaye iyambere mu gutanga imiyoboro ya karubone mu majyaruguru y’Ubushinwa, izwiho serivisi nziza, ibicuruzwa byiza, ndetse n’ibisubizo byuzuye.
Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.
Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
Nyamuneka twandikire, tuzaguha imiyoboro yo mu rwego rwo hejuru, ibyuma bisanzwe hamwe na serivisi zumwuga kandi nziza.Botop itegereje kugukorera.
