Cao e river, as the biggest tributary of QianTang River.   which the total length of the main stream is 193 km. And most of the river is an important industrial and agricultural water source in the coastal areas, with water diversion projects such as the Xiapu Gate are built; The downstream shipping capacity is relatively strong, of which Cao'e Port is an important port.

Last month, A company ordered 36 sets of standard steel buoys from our ZAZ  as the lateral buoys for the Cao e river , and it took us about 30 days to complete this order. The Steel Buoys  are a standard steel buoy designed for rivers estuaries and moderately exposed open seas.  With the diameter 1500mm and the thickness of steel plate 8mm, we believe our standard steel buoys will offer a good service in Cao e river.
