Summada Kooxda Shiinaha ee Tayada Sare leh oo aan Xumaan/ERW alxan lahayn/Kaarboon/Alloy Galvanized Square/wareega Biyo-Kuliyaha-la'aanta ah/Tubabka Biraha Kulaylka
Dulmar
Hadafkayagu had iyo jeer waa inaan u horumarino alaab-qeybiyaha casriga ah ee tignoolajiyada sare iyo aaladaha isgaadhsiinta anagoo bixinayna nakhshad qiimeed lagu daray, wax soo saar heer caalami ah, iyo awoodaha dayactirka bilaa Seamless/ERW welded Stainless/Carbon/Alloy Galvanized Square/wareega birta birta ah ee aan sinnayn, Badeecadayadu waxay u dhoofisay Bariga Dhexe, Yurub, Kuuriya, Vietname, Ciraaq, Ruushka iyo dalal kale. Ka fiirsashada hore si aad u abuurto wada shaqayn fantastik ah oo waarta oo ay kula weheliso mustaqbalka la arki karo! Waxaan helnay xalalka ugu fiican iyo iibka takhasuska leh iyo kooxda farsamada. Iyadoo horumarinta shirkadeena, waxaan awoodnaa inaan macaamiisha u gudbino alaabta ugu fiican, taageero farsamo oo wanaagsan, adeegga iibka ka dib.
Codsiga
Waxaa inta badan loo isticmaalaa qaybaha xoogga iyo cadaadiska, iyo ujeedada guud uumiga, biyaha, gaaska iyo tuubooyinka hawada.
