Amapayipi we-DTH
Ipayipi lokubhoboza ipayipi lensimbi elinamandla aphezulu elisetshenziswa ekubhobozeni.Kuye ngendlela yokubhoboza kanye nenjongo yokubhoboza, amapayipi afika ngokuqina nobude obuhlukene, ubude obuvame kakhulu bungamamitha angu-3-10.Amapayipi okubhoboza ahlanganiswe ndawonye ngamunye ngamunye njengoba umshini wokubhola uqhubeka ujula etsheni.Ehlangene, amapayipi akha intambo yokubhoboza, enganwebeka amakhilomitha ambalwa phansi emhlabathini.
I-Raw Material: Ipayipi eligoqiwe elishisayo elingenamthungo, lisuka ku-BAO STEEL/TPCO/BAO GANG njalo njalo, Ngokuqinile ngokuhambisana nokuhlolwa kwamazinga afanele, ngendawo yokukhiqiza, ukuhlola indawo yokucubungula kabili, ukuze kuqinisekiswe ikhwalithi yezinto ezingavuthiwe.
