Black iron wire, also called black wire or Annealed Wire, soft annealed wire, annealed iron wire or just annealed steel wire comes in the form of coil wire or cut wire. Mostly used in construction or daily use as binding material, or material for weaving wire mesh. We can produce two kinds of black iron wire, one is hard drawn wire, another is soft annealed wire.

Hard drawn wire
Hard drawn wire is the suitable material of iron nail, wire mesh, craftwork and so on.
Wire Guage: BWG8 ~ 23 #.
Wire Diameter: 4mm ~ 0.8mm.
Tensile Strength: 500~980 N/mm2.
Coil weight: 25kg, 50kg, 100kg, 200kg in normal coils 400~500 Kg or by Z2, Z3 coils.
Packing: wrapped with PE film inside, outside PVC woven cloth or Hessian cloth, Or can be put on wooden pallet.

Soft annealed wire
Types: Black soft annealed wire & Bright soft annealed wire or is named Soft annealed wire oxygen free. Black annealed wire which is made of iron wire, mainly used as tie wire or binding wire in construction. The Black annealed iron wire can also know as the Soft Anneal iron wire.
Diameter: BWG16, 18#, 19#, 20#, 22#, are the most popular sizes for sale.
Packing: in coil, by spool, or can be cut into sizes for binding/bundle.
Uses: Black annealed wire is used as tie wire or baling wire in building, parks and daily binding.

Plain Weave: Each weft wire passes over one and under one warp wire, and each warp wire passes over one and under one weft wire, every weft wire have and warp wire the same diameter.
Twill: Wire Cloth in which each warp wire and each shute wire passes successively over and under the two adjacent wires -- in both the warp and shute directions. This over and under movement is shifted one wire with each pass of the shuttle. This pattern permits the weaving of heavier wires in varying meshes.
Plain Dutch Weave: Similar interlacing as in Plain Weave, except the warp wires are larger diameter than the shute wires. The lighter shute wires are driven up close thus forming a dense filtering medium. This weave displays a tapered or wedge-shaped opening.
Twill Dutch: This filter cloth specification technically combines the Twill Weave and Dutch Weave described above. The larger diameter warp wires successively pass over and under the lighter diameter shute wires. Each pass of the shute wires shifts the over and under movement one wire. The shute wires are driven up close, resulting in a tightly woven filter cloth with tapered or wedge shaped openings.
Twill Dutch Double: Very similar to Twill Dutch Weave, but by proper selection of the wire sizes, the shute wires actually overlap each other when driven up tight into position. This permits double the wires per inch in the shute direction. This type of wire cloth is usually considered a Micronic Grade filter cloth.
Stranded: In this type of weave, both the warp and shute wires are made up of separate wires, rather than a single wire. This weave is woven in the twill pattern, producing an exceptionally strong and tight mesh.

It normally goes from wire rod, wire drawing, annealing. Then it can be oil tampered to add the anti-rusting property.

With oxygen free annealing line, we process annealed wire from 8# to 38#.

Annealed wire can be further processed into a variety of forms, including:
Straightened Cut Wire;
U Type Wire;
Loop Tie Wire;
Rebar Tie Wire;
Other forms.

Barbed Wire Fences Installation Steps and Tips
1. Select end and corner locations.

2. Install 6" × 8' wood post H-Brace assembly for ends and double corner H-Brace assemblies for corners. Should be installed in ground.
3.5' to 4' leaving 4' out of ground adjust post length if taller fence is required.

3. Carefully unroll end of 4' to 8' of barbed wire and fasten by wrapping around starting post and back onto itself at desired height for lowest strand.

4. Carefully unroll the barbed wire to end of fence.

5. Tension wire with Chain Wire Strainer at end. Cut wire to length and fasten wire at desired height as done at the beginning.

6. Cut barbed wire to length and fasten wire as done at the beginning.

7. The first wire should be adjusted (to obtain a straight line) along the fence line with light tension by picking wire up to a height of 4' to 6' then dropping wire. This

process should be repeated until straight line from beginning to end is achieved. This process will allow wire to fall creating a straight line for the fence to follow.

8. Using the first wire as a straight line, install line posts (wood or steel) at 15' to 20' apart, adjusting distance as necessary. (High- pressure fences like feed lots will

need heavier posts, closer together.)

9. Fasten barbed wire to T post with wire clip (usually provided with new T posts) and/or staple barbed wire to wood posts leaving room for wire to “float” when stapled (Do

not staple wire tight to post.)

10. When installing line posts make sure that any post that will have strain (vertical or horizontal) on it is stout and secure enough to take the strain. As in wood post 5" to

6" × 8' (multiples if necessary) in dips or other low areas and on crowns or high areas.

11. Repeat necessary process for additional wires.

The additional installation of a one or more “non-barbed” electrified wire can offer an additional “pain barrier” as well as a feeder wire to barbed wire systems.

Quality Control: Wire checking; quality control and checking of every stage of production; checking of finished products.
