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.

Cold wire drawing is a kind of cold processing of metal. The raw material is wire rod, which is produced by peeling, galvanizing and other processes. Galvanized cold drawing is used more in building materials. Its testing standards are also different. The strength of cold drawing is relatively high. Because of the high strength of steel, it plays a very important role in construction. It saves the construction steel in building materials, and also reduces the cost of the project. It also plays a very important role in the structure of concrete.

Zinc dipping time should be adjusted according to the thickness of wire diameter. The method of adjustment is to use the lead screw above the zinc pot, the length of the distance to the ceramic sinking roller. Thick wire diameter zinc dipping time should be long, fine wire diameter zinc dipping time should be short, zinc dipping length is in the range of 2~3.5m, which is also to reduce the zinc consumption of steel wire, is an aspect of maintaining the uniformity of zinc layer.

Temporary rust prevention is to prepare for the completion of the mission of the protective layer to be removed. The methods include: cajoling corrosion inhibitors, coating antirust oil, peeling molecular compound plastics, drying air, vacuuming, etc. Change the internal structure of the metal: new chromium, nickel and other alloy elements made of stainless steel, but the alloy is not much, expensive, difficult to produce widespread application.

Hook net: hook net also known as diamond net, rhombus net, slope protection net. It is widely used in warehouse, east and west cold storage, protection reinforcement, park, zoo fence, Marine fishing gate and construction site fence, mechanical equipment protection, highway guardrail, sports place purse Seine, road green belt protection net.

5, after the light plating should be carried out light treatment.

Cold drawing wire is a metal cold processing, with wire rod as raw material, that is, the mouth of the steel bar. Cold drawing wire is a product produced by a series of processes such as shell stripping, which is a common wire. In the development and production of metal materials, cold drawing wire is a very common material, its performance is good, the range of use is very wide, manufacturers in processing are the use of cold processing to produce.
