China Sch40 A53 A106 API 5L Dhuumaha Birta Kaarboonka ee aan Xumaan iyo Alxan
Dulmar
Raadintayada weligeed ah waa habdhaqanka "tixgelinta suuqa, tixgelin caadadii, tixgelin sayniska" iyo sidoo kale aragtida "tayada aasaasiga ah, rumaysad ku leh bilowga iyo maamulka sare" ee Dhuumaha Birta Carbon ee aan kala go 'lahayn iyo welded Marka aynu si adag u helno shaqadayada, waxa sida caadiga ah nagu tiirsanaa macmiilkayaga alaabada tuubooyinka birta. Nala soo xiriir maanta wixii faahfaahin dheeraad ah! Kooxdayadu waxay si fiican u garanayaan baahida suuqa ee dalal kala duwan, waxayna awood u leeyihiin inay ku keenaan badeecooyin tayo leh oo ku habboon qiimaha ugu fiican ee suuqyada kala duwan. Shirkaddayadu waxay mar hore samaysay koox khabiir ah, hal-abuur leh oo mas'uul ah si ay u horumariyaan macaamiisha leh mabda'a guuleysiga badan.
Codsiga
Waxaa inta badan loo isticmaalaa qaybaha xoogga iyo cadaadiska, iyo ujeedada guud uumiga, biyaha, gaaska iyo tuubooyinka hawada.
