2019 Ubwino Wabwino China Q235 Wotentha Woviikidwa Wamalata Wozungulira Chitoliro Chachitsulo Chosunga Madzi
Kufotokozera Kwachidule:
Tsatanetsatane wa Zamalonda
Zolemba Zamalonda
Bizinesiyo imatsatira malingaliro a "Khalani No.1 wapamwamba kwambiri, wokhazikika pangongole ndi kukhulupirika pakukula", ipitilizabe kupereka chiyembekezo cham'mbuyomu komanso chatsopano kuchokera kunyumba ndi kunja kwa 2019 Good Quality China Q235 Hot Dipped. Paipi Yachitsulo Yozungulira Yopangira Madzi, Pokhala gulu laling'ono lomwe likukulirakulira, mwina sitingapambane, koma takhala tikuyesetsa momwe tingathere kukhala bwenzi lanu labwino kwambiri.
Bizinesiyo imathandizira malingaliro a "Khalani No.1 wapamwamba kwambiri, khalani ozikidwa pangongole ndi kukhulupirika pakukula", ipitilizabe kutumikira zoyembekeza zam'mbuyomu komanso zatsopano kuchokera kunyumba ndi kutsidya kwa nyanja mwachanguChina 10# 20# Q195 Q235 Q345 42CrMo 16mn St52, Galvanized Gi, Timatengera zida zapamwamba zopangira ndi ukadaulo, ndi zida zabwino zoyesera ndi njira zowonetsetsa kuti mankhwala athu ali abwino. Ndi luso lathu lapamwamba, kasamalidwe ka sayansi, magulu abwino kwambiri, ndi ntchito zachidwi, mayankho athu amakondedwa ndi makasitomala apakhomo ndi akunja. Ndi chithandizo chanu, tipanga mawa abwinoko!
