Raw Material For Concertina

The razor edge concertina coils or punchedtape concertina wire coils are spirals consisting of a sharp-edged tape crimped to a spring steel core wire duly galvanized against rusting. Each turn of the concertina coil has a series of sharp edges (barbs) all along its length at regular intervals.

We offer wide range of G.I. spring steel core wire for manufacturing concertina coils of 2.60 MM, with zinc coating of 100 GSM to 250 GSM, as required by the customer.
