Dhuumaha birta ee qaboojiya waa nooc ka mid ah tuubooyinka birta, taas oo ah, waxaa loo kala saaraa iyadoo loo eegayo hababka wax soo saarka ee kala duwan, taas oo ka duwan tuubooyinka kulul (ballaadhin) ee kulul. Inta lagu jiro habka ballaarinta dhexroorka tuubada dhogorta ee bannaan ama tuubada alaabta ceeriin, tiro badan oo ah hababka sawirka qabow ayaa la sameeyaa. Saxnaanta iyo tayada dusha sare ayaa iska cad inay ka sarreeyaan kuwa tuubada birta ah ee kulul, laakiin caqabadaha tignoolajiyada awgeed, dhexroorkeeda iyo dhererkeeda ayaa xaddidan ilaa xad.

Tuubooyinka birta ah ee qabow-duuban waxaa ka mid ah tuubooyinka birta ee dhuuban ee kaarboon, tuubooyinka birta khafiifka ah ee alloy, tuubooyinka birta khafiifka ah ee aan khafiifka ahayn iyo tuubooyinka birta qaabaysan ee gaarka ah marka lagu daro tubooyinka birta caadiga ah, tuubooyinka birta kuleyliyaha cadaadiska dhexdhexaadka ah Tuubooyinka birta kuleyliyaha cadaadiska sare leh, tuubooyinka birta ah, tuubooyinka dildilaaca batroolka, tuubooyinka mashiinada, tuubooyinka derbiga qaro weyn, dhexroor yar tuubooyinka qaboojinta caaryada
Tuubooyin bir ah oo qabow-jiiday waa tuubo bir ah oo sax ah oo qabow leh oo leh saxnaanta cabbirka sare iyo dhammays wanaagsan oo dusha sare ah oo loogu talagalay qaab dhismeedka farsamada iyo qalabka hawo-biyoodka. Dhuumaha birta saxda ah ee saxda ah ee saxda ah ee qabow waxay badbaadisaa birta, waxay wanaajisaa waxtarka mashiinka waxayna badbaadisaa tamarta. Tuubo bir ah oo aan fiicneyn oo leh saxnaanta cabbirka adag (kala duwanaanta dulqaadka) ee dhexroorka gudaha iyo dibadda, simanaanta wanaagsan, wareegsanaanta iyo toosnaanta dusha gudaha iyo dibadda iyo dhumucda derbiga lebbisan.
Sida warshadaha alaabta biraha ee China keentay shirkadaha, ganacsiga birta qaranka iyo saadka "Boqol ganacsi iimaan wanaagsan", shirkadaha ganacsiga birta Shiinaha, "Top 100 shirkadaha gaarka loo leeyahay ee Shanghai". Shanghai Zhanzhi warshadaha Group Co., Ltd., (gaaban in Zhanzhi Group ) waxay qaadataa "Integrity, Practicity, Innovation, Win-Win" oo ah mabda'a hawlgalka kaliya, had iyo jeer waxay ku adkeystaan gelinta baahida macaamiisha meesha ugu horeysa.
