What is chain link fence?
Chain link fence is one type weaving fence, with the materials of galvanized wire, PVC coated wire, or galvanized and PVC coated wire, used in gardens, parks, road sides and housing. Chain link fabric is knitted and fastened into rolls automatically by chain link machine. The knitting process is that screwing the coiled wire into each other forms a flat coil.
In order to establish a stable, reliable and durable mesh fence for you, not only galvanized or PVC coated chain link fence, but also steel fence installation accessories is supplied by us. The most popular are galvanized chain link fence, which has good resistance to atmospheric corrosion. However, PVC coated chain-link has better durability.

Fencing height: 0.6 - 3.5 m;
Zinc on the wire 60-90 g/m2;
Edge types: bent or twisted;
Roll length: 10m - 50m;
Packing: the rolls are packed with paper or plastic film and tied crosswise.
Chain link fence - razor barbed wire for high security
Barbed wire as highly physical obstacle for intruders and wildlife is often used together with chain link fence. As security fences, razor barbed wire-chain link fence is a perfect choosing. Chain link fencing can forbid climbing. Barbed wire or razor wire in the above of chain fencing provides greater security. It is ideal for warehouses, construction sites, closed areas, airports, oil terminals, parking lots and other land to which entrance is strictly limited.

Barbed wire in three twist types with a variety of sizes

Barbed wire is made with high quality low carbon steel wire with the automatic twist machine. It is commonly used in grass field edges, railway, high way, prison and the privacy fields for separation.
Barbed wire have three common twist types: single twist barbed wire, double twist barbed wire and traditional twist barbed wire.
Barbed wire includes line wire and barbed wire. In general, the wire diameter of line wire is larger than that of barbed wire. The barbed wire twist types depends on the twist type of line wire and barb wire. And the line wire sometime is single wire, sometimes is double wire.
Single Barbed Wire
Single barbed wire is a kind of security fences with sharp edges and high-tensile wire.
Wire Materials: Galvanized steel wire, low carbon steel wire, stainless steel wire, PVC coated iron wire in blue, green, yellow and other colors.
Specifications:
Barbed wire consist of line wire and barbed wire. Generally, line wire gauge is larger than barbed wire. Below data, the former is line wire, the latter is barbed wire gauge.
Wire Gauge: 180 # × 180 #, 200 # × 200 #, 220 # × 200 #, 220 # × 220 #, 250 # × 220 #, 260 # × 220 #, 270 # × 220 #, 280 # × 220 #, 300 # × 200 #, 200 # × 200 #.
Barbs Spacing: 1.96"--5.90".
Barbed distance: 3-6inch.
Applications: Single Barbed Wire has been widely used in military field, prisons, detention houses, government buildings and other national security facilities. Recently years, barbed tape has apparently become the most popular high-class fencing wire for not only military and national security applications, but also for cottage and society fence, and other private building.
ouble barbed wire
Double barbed wire has two line wires twisted together with wire barbs attached. The wire is normally attached to wooden fence posts using a curved nail. This type is much safer than single barbed wire with the high tension.
materials: hot-dipped galvanized wire, electro galvanized wire, PVC coated wire.
specifications:
Barb spacing: 3" - 6".
Wire diameter: 1mm - 3.5mm.
Note: After galvanizing or plastic coating, the wire gauge is larger.
The length or weight per coil can be as customer need.
applications: with high tensile, barbed wire is the perfect selection for cattle fencing and for the top wire above a traditional stock fence. It is also suitable for farm fencing, grassland farm. Barbed wire with chain link fence or welded fence can be found in use in railway, airport, high protection areas.
Barbed wire is relatively cheap and moderately effective. The barbs are painful if pushed against, thereby discouraging the horses from pushing against the fence.
Note: the barb is quite sharp and easily the barbs can cause serious injuries. When install the barbed wire fence, you should take the gloves for protection.
raditional barbed wire is made of low carbon steel wire or galvanized wire with the twisting processing by the barbed wire machines. Compared with single and double twist, traditional barbed wire is more security.
materials: low carbon steel wire, PVC coated wire, zinc coated wire, iron wire.
Uses and applications:
Land fencing and protection;
Animal cages;
Home and business security fencing aid.
As fencing with chain link fence or welded wire mesh fence.
Features:
No stretching required when installing;
Barbs fixed between wires;
Adaptable for all fencing needs.
Uniformly zinc coated.

The Development of Barbed Wire

Prior to 1863, several individuals created forms of fencing that could be considered as barbed wire. None of these creations ever reached the mass market. In 1863 by Michael Kelly developed a type of fence with points affixed to twisted strands of wire.
Had his invention been properly promoted, he could have gained distinction as the Father of Barbed Wire. It wasn't until ten years later that another inventor filed a patent that would spark the development of the barbed wire industry.

At the county fair in DeKalb, Illinois in 1873, Henry M. Rose had on exhibit a new idea in fencing. It was a wooden rail with a series of sharp spikes protruding from the sides of the rail. The fence rail, patented earlier that year on May 13, was designed to be attached to an existing fence to "prick" an animal when it came into contact with the rail and keep livestock from breaking through.

This fence attracted the attention of each of the three men, Joseph Glidden, Jacob Haish, and Isaac Ellwood. Each man had the idea to improve upon Rose's fence by attaching the spikes (barbs) directly to a piece of wire. Each went their separate ways to work on an invention that would soon bring them together.

Legend states that Glidden's wife Lucinda encouraged him with his idea to enclose her garden. Glidden experimented by bending a short wire around a long strand of straight wire, by modifying a coffee mill. Two pins on one side of the mill, one centered and the other just enough off center to allow a wire to fit in between. When the crank was turned, the pins twisted the wire to form a loop. The wire was then clipped off approximately one inch on each end at an angle to form a sharp point. Barbs were placed on one of two parallel strands of wire. The two strands of wire were attached to a hook on the side of an old grinding wheel. As the barbs were positioned, the wheel was turned twisting the two strands of wire and locking the barbs in place.

During this time, Isaac Ellwood, a hardware merchant, had been unsuccessful in perfecting his own version of barbed wire. When Joseph Glidden was awarded a patent on November 24, 1874 for his creation known as "The Winner," he and Ellwood formed a partnership to establish The Barb Fence Company.

Jacob Haish also had patented his own wire by this time but had not made a serious attempt to promote and sell it. Haish, wanting the credit for barbed wire himself, didn't like the idea of Glidden and Ellwood forming a partnership and strived to bring them down. When Haish learned that Glidden had applied for a patent in late 1873, but was denied, Haish filed a patent for his creation, the "S-Barb" in July of 1874. A few days later he filed interference papers against Glidden and an intense legal dispute ensued. Even though Haish was awarded a patent first, Glidden won the dispute because he had filed his patent before Haish. Unwilling to admit defeat, Haish claimed the title of "the inventor of barbed wire." Nevertheless, it was Joseph Glidden who became known as the "Father of Barbed Wire."


Kansas Fence Laws

With miles of fences being constructed daily, there arose a need to define a lawful fence. In Kansas, lawmakers debated the issue and wrote legally binding definitions of proper fencing. When cropland adjoined land used for grazing, the statute of Kansas placed the burden on the landowner to fence out cattle lawfully at large. This determination was based on free range grazing laws which permitted cattle to graze unrestrained. Although the farmer was responsible for constructing the fence, he was afforded many advantages provided the fence met established criteria.

If an animal breached a fence, and trespassed upon cultivated or other fenced land, the animal's owner was deemed responsible for the damage. The law further granted possession of the animal to the landowner until such time as he was properly compensated.
