COVID-19 is a global challenge facing mankind. In order to effectively control the spread of the epidemic, regional isolation control for different countries and regions is an effective means of containment. The border line of neighboring countries is an area where it is difficult to control the cross-border movement of people. In order to quickly isolate the cross-border movement of people in the border areas, setting up a razor wire fence near the border line is a simple and effective measure.

Advantages of razor wire mesh:
1. Simple structure and convenient manufacture, suitable for mass processing, production and use.
2. It can effectively play the role of isolation and protection, with obvious functional effect. It is widely used in border lines, border posts, prisons, railways and other fields with common and high security requirements.
3. Due to the wide source of materials, low cost and low price, it is an economic isolation and protection facility.
4. A variety of standard specifications are available, and special specifications can be customized on demand, which is easy to customize and process.

Material and anti-corrosion of razor wire mesh:
1. The materials used for the blade wire mesh include: fine steel wire and thin steel plate.
2. Steel wire materials include: galvanized wire, hot-dip galvanized wire and 304 stainless steel wire.
3. Steel plate material: galvanized plate, 304 stainless steel plate.
4. Anti corrosion performance: 304 stainless steel has better anti rust ability and higher cost than galvanized material. Hot dip galvanized materials generally have higher zinc layer thickness and better corrosion resistance than electro galvanized materials, which also depends on the value of their respective amount of zinc.
