Itsinda rya Tianjin Rainbow Steel ryashinzwe mu 2000, riherereye mu Mujyi wa Tianjin. Nyuma y’iterambere ry’imyaka 20 ishize, Rainbow Steel yabaye ikigo cy’ibyuma n’ibyuma bivanze mu byuma bya galvanised.Umuyoboro w'icyuma, galvanizeMalayika w'icyumaakabari, imiterere ya galvanize, galvanize niniImiterere y'icyumaku bwubatsi. Ikipe yacu ifite ikoranabuhanga mu nganda, ubunararibonye mu gutunganya, ubushobozi mu by'ubuhanga n'ibikoresho bigezweho. Abakozi bacu ni abanyabwenge kandi bakora cyane. Ibicuruzwa byacu birimo inyubako nini z'ibyuma zo kubaka, ibikoresho byo mu muhanda munini, inkingi z'icyuma cya gari ya moshi yihuta, ibikoresho by'icyuma byo munsi y'ubutaka cyangwa ibyuma, sisitemu yo gushyiraho imirasire y'izuba, n'indi mirimo ikomeye mu byuma. Umuyoboro w'icyuma urimo irangi ukoreshwa cyane mu mazi cyangwa mu yandi mazi yohereza amazi munsi y'ubutaka. Umurambararo w'umusaruro ni hagati ya mm 219 na mm 1016. Igice gifite impera y'uruziga cyangwa igice cy'urukiramende. Irangi ry'imbere rya epoxy rishobora gukoreshwa mu kohereza amazi meza kandi ntabwo ari uburozi.
