A barrier structure includes a continuous piece of elongated metal tape. The metal tape includes barbs spaced along an elongate body. Each of the barbs is connected securely to a barb root, and each barb root is connected securely to the elongate body. A first region of the elongate body is adjacent to each barb root, and a second region of the elongate body is adjacent to each first region distal from the barb root. A third region of the elongate body adjacent to each second region distal from the first region extends lengthwise from each second region and meets a corresponding third region that is extending lengthwise away from another second region. Each second region extends transversely and inwardly from the adjacent first region and the adjacent third region.
1. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:
an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;
barb roots spaced along said tape and secured to said flanges;
a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, and each of said tapered barbs forming a barb point;
a first region of said elongate body adjacent to the barb root;
a second region of said elongate body adjacent to the first region distal from the adjacent barb root;
a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;
wherein:
a width of the flanges in the first region is greater than a width of the flanges in the second region, and wherein a width of the flanges in the third region is greater than the width of the flanges in the second region; and
said channel does not receive a reinforcing wire.
2. The structure of claim 1 , wherein each second region comprises an arcuate cutout.
3. The structure of claim 1 , wherein:
the continuous piece of elongated metal tape has a plurality of first regions, a plurality of second regions, and a plurality of third regions; and
a distance between the barb points of said pair of barbs is the same as a distance between adjacent ones of said second regions of said tape.
4. A barrier structure comprising a continuous piece of elongated metal tape, said metal tape comprising:
an elongate body defining a longitudinally extending channel and an elongate flange extending transversely from each side of said channel;
barb roots spaced along said tape and secured to said flanges;
a pair of tapered barbs secured to a barb root, said pair of tapered barbs extending in opposing longitudinal directions, and each of said tapered barbs forming a barb point;
a first region of said elongate body adjacent to the barb root;
a second region of said elongate body adjacent to the first region distal from the adjacent barb root;
a third region of said elongate body adjacent to the second region distal from said first region, the third region extending lengthwise from the second region and meeting a corresponding third region extending lengthwise away from another second region;
wherein:
the second region extends inwardly from the first region to the third region;
the width of the flanges in the first region is greater than the width of the flanges in each third region; and
said channel describes an arc extending between the flanges, the arc extending less or equal to approximately 180°.
5. The structure of claim 4 , wherein a width of each of the flanges in each first region is greater than a width of each of the flanges in each second region, and wherein a width of each of the flanges in each third region is greater than a width of each of the flanges in each second region.
6. The structure of claim 4 , wherein a width of each of the flanges in each second region is equal to a width of each of the flanges in each third region.
7. The structure of claim 4 , wherein:
the continuous piece of elongated metal tape has a plurality of first regions, a plurality of second regions, and a plurality of third regions; and
a distance between the barb points of said pair of barbs is approximately the same as the distance between adjacent ones of said second regions of said tape.
