A wire/chain installing and tensioning device includes a wire-retaining rod, a post-engaging bracket, and a rod-receiving slot. The wire-retaining rod includes a rod body, a wire-engagement head, and a torque-receiving head. The rod-receiving slot normally traversing through the post-engaging bracket to receives the rod body. The wire-engagement head that receives and holds a wire to be tensioned is rotatably connected around a non-threaded section of the rod body. The torque-receiving head is terminally connected to a threaded section of the rod body and positioned opposite the wire-engagement head. The threaded section of the rod body is threadably engaged within the rod-receiving slot thus functioning as a linear actuator when the torque-receiving head is rotated by an external torque tool.

A textured workpiece includes a body having an outer surface with at least a first surface portion. At least one of the body and the first surface portion is non-planar. A first set of barbs extends from and is integral with the first surface portion. A first set of grooves is formed in the first surface portion. Each barb of the first set barbs is associated with a respective one of the grooves of the first set of grooves. The workpiece can be used as reinforcing bar (rebar).

A new type of electrostatic barbed wire includes a plurality of barbs. The plurality of the barbs are woven together to form a fixed body with a strip-like structure. Ends of the plurality of the barbs are located outside the fixed body. A barbed net is also disclosed. The barbed net is woven by the electrostatic barbed wire. In the present application, the proposed new type of electrostatic barbed wire and barbed net are woven with the plurality of the barbs, and a processing technique thereof is simple.
