Standard materials for razor type concertina razor wire are either galvanized or stainless steel. The concertina razor wire is made of 0.5mm thick hot-galvanized steel sheet and 2.5mm thick high-carbon galvanized wire. These coils are compressed for transportation, and then stretched for use.
 
These coils are compressed for transportation, and then stretched for use. Concertina Razor Wire has two formations: spiral formation (unclipped) and concertina formation (clipped).Each spiral circle is joined by three, five or seven rows of connector clips, depending on the diameter of the circle. This condenses the spacing of the spirals. 
 
Razor wire in hot dipped galvanized sheet is widely used in many fields for its lower  cost compared with stainless steel razor wire. It can be set up on the top of military field, prisons, detention houses, government buildings and other national security facilities. In recent years, barbed tape has apparently become the most popular high-class fencing wire for not only military and national security applications, but also for cottage and society fence, and other private buildings. If you need this product, please contact Hebei Zhengyang Wire Mesh Products Co., Ltd, E-mail:sun@sunwiremesh.com
