The first is the cost of raw materials galvanized sheet and galvanized wire, some specifications and waste calculation and so on. Then there is the cost of mechanical processing process and manual processing process. Finally, there is the cost of packing and shipping. In recent years, due to the rapid development of thorn rope manufacturers, so the profit margin of blade thorn rope is not particularly broad.

When there is a problem in the process of galvanizing, check the temperature and current density first, and then measure and adjust the content of zinc and sodium hydroxide in the bath through the analysis of the bath. Whether DPE levels are low can be determined by Hull cell test.

PVC coated barbed rope is widely used for railway highway protection, but also for safety protection of rivers, embankments and seawalls, so as to better protect the safety of people and animals.
