20 # Chitoliro chachitsulo
20 # chitsulondi wazitsulo zapamwamba kwambiri za carbon carbon steel, ozizira-extruded ndi zitsulo zolimba. Chitsulocho chili ndi mphamvu zochepa, kulimba bwino, pulasitiki komanso kutsekemera. Ndi yachitsulo chotsika kwambiri cha carbon carbon steel, chozizira kwambiri komanso cholimba. Chitsulocho chimakhala ndi mphamvu zochepa, kulimba bwino, pulasitiki komanso kutsekemera. Nthawi zambiri amagwiritsidwa ntchito popanga mapaipi opanda msoko okhala ndi nkhawa zochepa komanso zolimba kwambiri.

1. Nthawi yobweretsera: Kusungirako kwakukulu kuonetsetsa kuti nthawi yochepa yobereka, makamaka masiku 5-7.
2. Kasamalidwe kamitengo: Zothandizira zomwe zilipo komanso luso lakasamalidwe lamitengo titha kupereka zophatikiza zoyenera kwambiri pazosowa za kasitomala.
3. Chigawo chapamwamba cha mphero: Ikhoza kupereka chiphaso chokwanira ndi zikalata zoyenerera kuti zitsimikizire zapamwamba ndi kupereka chithandizo kwa ma tender.
4. Dongosolo lolimba la QC: Kuyang'ana kwapadziko lonse, kuyesa kwathunthu ndikuwonetsa, kuwunika kwa gulu lachitatu
5. Pambuyo utumiki: mankhwala onse traceable, Kufufuza gwero la udindo
