Galvanized iron wires must be packed in good condition, bound neatly and orderly, and bound with an inward end to prevent scratches during transportation. The inspection standard of galvanized iron wire also includes the tensile test. This item is determined according to the material of the galvanized wire order ordered by the customer, and it needs to be tested by comparing the raw material list.

  • The main raw materials of blade barbed wire are galvanized wire and galvanized sheet. Because the price of galvanized sheet is more expensive than galvanized wire, it is directly reflected in the price of blade barbed wire sales. There is also the difference in processing technology also leads to the difference in the price of the blade barbed rope. The traditional barbed rope is mechanically twisted, with relatively small labor consumption and high production efficiency. But the blade barbed rope is after the second mechanical processing in the artificial processing operations to appear. Therefore, there is a big gap between labor force and production efficiency. These factors lead to the price of the blade barbed rope is more expensive main factors.
