Product advantage:
Huayang is near to the material supply mill, Hebei Zhongtie Equipment Company, which reduce the material cost. At the same time, Huayang is 210 kilometers from Beijing, 150 kilometers from Tianjin City, 160 kilometers from Xingang port, with convenient transportation, which is convenient for customer’s visit and reduce the transportation cost. So HUAYANG BRAND pipe cost is lower than that of other company, which can make more profits for the customers.
