Concertina wire consists of high tensile strength core wire and a punched steel tape with barbs. The production process of combining the core with the steel tape is called roll forming. Here is a brief process of stainless steel concertina wire production.
First. Prepare t stainless steel coil sheet before production.
Second. Install stainless steel sheet to punching machine.
Third. Punch stainless steel sheet to sheet tapes with sharp barbs.
Fourth. The steel tape is tightly cold-crimped to the wire except barbs.
Fifth: Razor wire is manufactured
sixth. Clips are assembled for firm structure.
Seventh. Package coiled concertina wire by woven bags or carton.
