Barbed Wire

Barbed Wire Galvanized and PVC Coated, Specifications, Dimensions, and Case
Studies
Frishine supplies a wide range of galvanized barbed wires for temporary
enclosures, property boundaries, and security fencing.

Materials and Styles
We provide high quality barbed wire, available in hot-dipped galvanized,
electric galvanized, and PVC coated finishes. Made from Q195 steel, our barbed
wire has two strands and four-point barbs. With barb spacing of 3 to 6 inches
and a tolerance of ±1/2 inch.

Wire Gauge and Process

Traditional Twisted Style:
Traditional twisted barb wire has two strands of wire twisted together with
barbs inserted at intervals. Used for most perimeter fencing uses.
Positive/Straight Twisted Style:
Straight twisted barbed wire, is made with the wires twisted in a straight
alignment, creating a uniform and neat appearance.
Reverse/Negative Twisted Style:
The reverse or negative twisted style involves alternating the direction of the
twist at regular intervals. This barbed wire enhances the fence’s physical
strength and visual deterrent, ideal for high-security fences.

Customized Specifications
Adjustable Barb Spacing:
Barb spacing from 3 to 6 inches, for a range of security applications. Less
barb spacing for enhanced security areas, wider spacings for general boundary
fencing.
Wire Gauge Customization:
Common wire gauges include:
– 12.5 Gauge: Ideal for general-purpose fencing, offering a balance between
flexibility and strength.
– 14 Gauge: Provides a lighter, more economical option while still maintaining
adequate durability.
– 16 Gauge: Suitable for areas requiring finer, less intrusive fencing
solutions without compromising security.
Flexible Roll Lengths:
For various projects and minimize waste, Frishine offers galvanized barbed wire
in customizable roll lengths.
Commonly requested lengths include:
– 1320 feet (400 meters): Standard length for extensive perimeter fencing.
– 165 feet (50 meters): Suitable for smaller sections or repairs.
Custom Lengths: ensuring precise coverage and cost-efficiency.12 gauge barbed

Barbed Wire with Temporary Site Fencing
Case study: Using of barbed wire into a temporary site fencing solution for
perimeter security for a construction site. The fencing system combines welded
mesh temporary fence panels with barbed wire, supported by robust line posts,
and stabilized with struts. This system provides a high level of perimeter
security against unauthorized access while maintaining flexibility for
temporary installation.

Welded Mesh Temporary Fence Panels:
Size: 11 gauge (0.120″ or 3.0mm) galvanized iron (GI) welded mesh panels.
Welded mesh panels reinforced with vertical flat bars, 15mm wide by 5.0mm
thick, placed at intervals of 75mm (±2%), ensuring strength and durability.
The mesh dimensions 76.2mm x 12.70mm, with panels measuring 2.80 meters in
height and 2.91 meters in width. Each panel features 3D bending at three points
to provide additional rigidity and resistance against breaching.
Barbed Wire Specifications:
Atop the mesh panels, double stranded barbed wire with two strands of 12.5
gauge (0.098″ or 2.50mm) GI wire is installed, quality conforming to ASTM A121
or ASTM A641, Class III standards for Galvanized barbed wire. This barbed wire
adding an extra layer of security fencing top.
Support Posts and Installation:
The fencing system is supported by line posts, corner posts, end posts, and
pull posts made from pipe with a diameter of 88.90mm and SCH. 80 wall thickness
(7.62mm), ASTM A53 standards. These posts extend 2.70 meters above ground,
with an additional 1.0 meter buried for stability, and are topped with a 0.45
meter Y crank to support the barbed wire. Posts are spaced at 3.0 meter
intervals. Struts made from 60.30mm diameter. 40 pipe, with a wall thickness of
3.91mm, are installed every 3 meters to provide lateral support to the posts.
All steel components are hot-dip galvanized according to ASTM A123 to prevent
corrosion.
This combination of welded mesh panels and barbed wire creates a temporary
security fencing solution ideal for perimeter control. The use of high-quality
materials and producing according to international standards, ensure the
fencing system for specific needs of our clients.
