Mtundu waku Europe waku China 3PP 3PE Wopaka Chitoliro cha Carbon Steel
China 3PP 3PE Chophimba cha Chitoliro cha Chitsulo cha Carbon chopanda msoko
Kwa makulidwe osiyanasiyana 3 PE zokutira makulidwe ndi osiyana. Zomwe zaphatikizidwa kuti zigwiritsidwe ntchito

Mwachidule
Kugwiritsa ntchito
Amagwiritsidwa ntchito kwambiri popanga zitsulo zapamwamba kwambiri za carbon structural steel, low pressure medium pressure boiler pipe, super heat heat carbon steel pipe
Main Grade
Kalasi ya apamwamba mpweya structural zitsulo: 10 #, 20 #
