The first feeling of the positive and negative twisted wire protection fence is that the wire is too thin, and the protection effect is relatively small. So, what is the protective effect of the positive and negative twisted wire protection fence? Let's take a look!
Positive and negative twisted barbed wire protection fences are used on highways, the general wire is 170 wire, and the ordinary barbed wire is about 200-280 wire.
The material of the barbed wire protective fence used for the expressway is hot-dip galvanized steel wire, which is several times better than the hardness and tensile force of the iron wire. The tensile strength is 1200N and the wire is 350N.
Compared with the ordinary barbed wire, the positive and negative barbed wire protection fence has the same weight but the meter number will be longer. From the perspective of purchase, it can save some money for the user. So barbed wire is worth using.
