Electric resistance welding. This is by a combination of heavy electric current (applied at low voltage) passed through the junction of wires, combined with heavy mechanical pressure. A solid state thyristorregulated electronic control ensures very fine control of time (in cycles) and current amplitude (total phase angle). All the spacings between wires are controlled by an automatic mechanism of high reliability. Materials being used 1. The wires used in the fabric are cold drawn from controlled quality mild steel wire rods with carbon contents generally less than 0.15%. WWF is manufactured conforming to IS:15661982 with long and cross wire spacing varying from 25mm to 400mm.

Barriers are recommended for security in industrial and commercial applications. The latest innovation in barriers for ultimate security is the reinforced flanged version of barbed tape, which makes it strong and also long lasting high quality razor ribbon tapes are available in helical coils.
