Farqiga u dhexeeya birta wareega iyo baararka kale ee xoojinta waa sida soo socota:
1) Birta wareegsan ee birta ayaa muuqaalkeedu wareegsan yahay, iyada oo aan lahayn khadadka iyo feeraha, iyo biraha kale ee xoojinaya waxay leeyihiin xariijimo ku xardhan ama feeraha korkooda, taas oo keenta in yar oo ku dhajisan inta u dhaxaysa birta wareega iyo shubka, halka kuwa kale ee xoojinta ay leeyihiin dhejis weyn oo shub ah. .
2) Halabuurka ayaa kala duwan.birta wareegsan ee birta ah (birta darajada I) waxay iska leedahay birta kaarboonka ee caadiga ah, halka birta kale ay u badan yihiin birta alloy.3. Xooggu waa kala duwan yahay.Birta wareega birta waxay leedahay awood yar, halka birta kale ay leeyihiin awood sare, taas oo ah, birta wareega ee isla dhexroorka ah waxay qaadi kartaa xoog yar marka loo eego birta kale, laakiin caagadeedu way ka xoog badan tahay birta kale ee birta ah, taas oo ah, birta wareegsan. wuxuu leeyahay qallooc weyn ka hor inta aan la jiidin, halka biraha kale ay leeyihiin cillad yar ka hor inta aan la jiidin.
Birta wareegsan ee birta ayaa si weyn loogu isticmaalaa samaynta dhammaan noocyada qalabka, qalabka goynta, dhinta iyo qalabka cabbirka, qaybo ka mid ah warshadaha wax soo saarka mishiinka.Tusaale ahaan, 40Mn2 bir wareeg ah ayaa guud ahaan loo isticmaalaa xaalad demisay iyo xaalad dabcay, waxaa loo isticmaali karaa in lagu soo saaro qaybo ka shaqeeya culeys culus, sida shaft, shaft, axle, usha bistoonka, dirxiga, kabaalka, usha isku xirka, boodhka raran, maroojiska, giraanta xoojinta, guga iyo qaybo kale oo la demiyey oo dabcay.
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.
