hammering nail into concreteThe common weight standard of galvanized barbed rope is 25kg per coil, and the length of each coil varies from 220-250 meters according to the specifications of the barbed rope. And of course we all know that the heavier the disc the longer it is. But there is one point that is worth our attention, that is, the hollow inside the general larger disk is relatively small, and the hollow inside the lighter galvanized thorn rope is relatively large. The purpose of this is to reduce the number of bending of the thorn rope and make it easier and more beautiful when installing, on the other hand, it looks larger in appearance.
