Types of Fence

THIS SPECIFICATION COVERS THE FOLLOWING FENCE TYPES:

Standard barbed wire fences are suitable for most uses. Standard barbed wire fences are not suitable for controlling hogs.

[pic]

Suspension fences are similar to standard barbed wire fences, but line posts are spaced up to 100 feet apart. Suspension fences shall only be used for interior cross fencing. Suspension fences are not suitable for rough topography. Suspension fences shall not be used for sheep, goat, hog, or other small livestock control.

[pic]

Let down fences are constructed the same as standard barbed wire fence construction. The only difference is method of attaching the fence wires to the line posts. Let down fence sections may be installed where they are needed to prevent damage from heavy snow or big game movement.

[pic]

Woven, mesh, or chain link wire fence may be used where tight control of animals or people is needed. This type of fence shall only be used for confining livestock on irrigated pasture, cropland, or on privately owned forest or rangeland areas of less than 80 acres.

[pic]

Anchor and Brace Assemblies

BRACING IS THE MOST IMPORTANT COMPONENT OF POST AND WIRE TYPE FENCES. WIRE FENCES CAN EXERT UP TO 4000 POUNDS OF PRESSURE ON THE ANCHOR POSTS. ANCHOR POSTS NEED TO BE BRACED, MADE OF STEEL OR STOUT WOOD, AND BURIED DEEPLY TO WITHSTAND THIS KIND OF PRESSURE. BRACES ARE REQUIRED AT ALL CORNERS, GATES, AND AT ALL DEFINITE SLOPE BREAKS AND CHANGES IN FENCE ALIGNMENT.

[pic]

The maximum spacing for anchor and brace assemblies is as follows:

|Fence Type |Maximum Distance Between |

| |Anchor Posts |

|Barbed wire |1320 feet (80 rods) |

|Suspension Fence |1320 feet (80 rods) |

|Let Down Fence |1320 feet (80 rods |

|Woven Wire |330 feet (20 rods) |

|Mesh Wire |100 feet |

|Chain Link |100 feet |

End Braces

End brace assemblies shall be installed where there is only one direction of pull on the brace assembly, such as at gates or where the fence meets a natural barrier. Horizontal anchor and brace assemblies shall be used for all wooden anchor and brace assemblies.

Horizontal anchor and brace post assemblies are required for all suspension fences.

[pic]

Double span end brace assemblies are required for sandy or wet soil conditions, or areas with heavy animal pressure.

[pic]

[pic]

Double span end brace assemblies may be constructed as a double horizontal brace assembly, or as a horizontal and diagonal brace assembly.

Line Brace Assemblies

Line brace assemblies shall be installed where there are two directions of pull on the anchor post, such as at corners and in-line stretch posts. Line braces are constructed the same as end bracing, but with brace posts set in both direction of pull.

[pic]

[pic]

Double span line brace assemblies are required for sandy or wet soil conditions, or areas with heavy animal pressure.

[pic]

Single H Brace Assemblies

In a single H brace assembly, each post serves as both an anchor post, and a brace post. They are constructed the same as a single span horizontal end brace.

For fence sections that are less than 500 feet in length, where the distance and direction of pull are approximately equal, a single wooden H brace assembly can be used for line bracing. Tension wires shall be installed in both directions.

[pic]

Single Diagonal Brace Assemblies

Single wooden diagonal brace assemblies may be used for bracing angles in the fence line between standard line braces or end braces. Fence wires shall not be tied off to a diagonal brace assembly.

[pic]

Steel and Concrete Brace Assemblies

Steel angle iron or steel pipe set in concrete may be used for end and line bracing. Steel and concrete brace assemblies shall be constructed as single or double span horizontal brace assemblies, or as a diagonal brace assembly.

[pic]

Anchor and Brace Post Materials

Wooden anchor and brace posts shall have a minimum diameter of 6 inches.

Wooden posts shall have a minimum life expectancy of 10 years. Untreated juniper, oak, mesquite, black locust, and redwood posts may be used. Railroad ties in good condition may be used. Pine or other softwood posts must be commercially pressure treated.

Steel angle iron anchor and brace posts shall be a minimum of 2.5” x 2.5” x 0.25”, weighing at least 4 pounds per foot of length. Angle Iron anchor and brace posts shall be set in concrete.

Wooden posts and steel pipe posts greater than 6" in diameter shall be set in holes at least six (6) inches larger than the diameter of side dimensions of the posts. Earth backfill around posts shall be thoroughly tamped in layers not thicker that 4 inches and shall completely fill the posthole to the ground surface. Backfill shall be crowned up around posts at the ground surface.

Steel pipe less than 6 inches in diameter, angle iron, and rebar anchor and brace posts shall be set in a hole at least 36 inches deep and 12 inches in diameter. The bottom of the steel post shall be placed on a rock. The hole shall be filled with concrete in such a way as to allow the concrete to flow around the base of the post. The top of the concrete shall be mounded above ground level and sloped away from the post to prevent water from ponding around the base of the post.

Concrete shall be allowed to set for ten days before tension is applied to the brace assembly through tightening of wire.

Horizontal and Diagonal Braces

Horizontal braces shall be at least 6 feet in length. Wooden diagonal braces shall be a minimum of 10 feet in length.

Line Post Materials and Installation

Manufactured steel “T-posts” or “U-posts” with anchor plates weighing not less than 1.25 pounds per foot of length can be used. In saline-sodic soils, "T-posts" weighing not less than 1.33 pounds per foot of length shall be used. "T" or "U" posts shall be studded, embossed, notched, or punched for the attachment of wires. They shall be galvanized, painted, or enameled. T posts or U posts shall be driven into the ground until the top of the anchor plate is below ground level. Steel “T” or “U” posts shall be long enough to be driven into the ground to the required depth, as a minimum above the anchor plate, and extend not less than 2 inches and not more than 4 inches above the top wire.

Wooden line posts may be used. The minimum top diameter or width for wooden line posts shall be 3 inches. Wooden line post shall be set a minimum of 18 inches into the ground, or 24 inches in sandy soils. Wooden line posts shall have a minimum life expectancy of 10 years. Untreated juniper, oak, mesquite, black locust, and redwood posts may be used. Pine or other softwood posts must be treated with a preservative.

Line posts may be made from steel pipe that meets or exceeds the requirements for 2 inch nominal size standard steel pipe (Schedule 40). Used steel pipe may be used provided that it is approved by NRCS prior to construction as being of good quality and relatively free of pits and scaling. Steel pipe line post shall be set a minimum of 18 inches into the ground, or 24 inches in sandy soils.

Rock jack line posts may used on fence line sections with shallow, swampy, or expansive clay soils, or where line posts cannot be set in the ground due to underground utilities or cultural resources. Rock jack line posts shall be spaced the same as standard fence line posts.

[pic][pic]

Straddle jack line posts can be used to cross short sections where normal line posts cannot be installed. No more than 7 straddle jack line posts shall be set consecutively in a section of fence.

[pic]

To install straddle jacks, stretch the fence wires to the anchor posts of the brace assemblies for the fence section. Notch the straddle jack posts where they cross, and tie them together with two wraps of 9 gauge or heavier wire. Set the jack in place under the top fence wire and staple the top wire to one of the posts. Make the jack footing secure and wrap and tie the lower spread wire to each post.

A 50 pound or heavier rock shall be used to anchor the straddle jack. Make a sling around the rock using 2 strands of 9 gauge or heavier smooth wire. Support the rock on smaller stones. Twist the sling wires up around the lower fence wires and secure to the jack where the posts cross. Then remove the smaller support stones from under the anchor.

Stays

Stays shall be made of galvanized twisted wire, fiberglass, or they can be made from wood with a minimum diameter of 1.5 inch. Stays must not touch the ground on suspension fence line sections.

Sheep 5 Wire 6" - 12" - 19" - 27" - 36"

Cattle and Sheep 5" - 11" - 18" - 28" - 42"

Barbed Wire Spacing

Barbed wire fences shall be constructed as 3, 4, or 5 wire fences. Barbed wire fences installed to control cattle, and other large livestock, shall have the bottom wire at least 16 inches above the ground at each post. The top wire shall be at least 40 inches, and not more than 44 inches above the ground at the posts. Barbed wire fences installed to control sheep, goats, and other small livestock, shall have the bottom wire installed at least 6 inches above the ground at each post. The top wire shall be at least 36 inches above the ground, and not more than 44 inches above the ground.

Woven Wire

Woven wire fences may be used for confinement fencing in corrals, feed lots, and small acreage areas. Each woven-wire fence type has a tag with a design number that accurately describes the configuration of the fencing material. In the design number, the first one or two numbers relate the number of line wires; the next two numbers to the right specify the height of the wire in inches; the next to last number grouping (either the number 6 or the number 12) identifies the spacing of vertical stay wires; and the final one or two numbers give the gauge of intermediate wires. For example, woven wire with design no. 726-12-11 has 7 line wires, is 26 inches high, the vertical stays are spaced 12 inches apart, and the intermediate wires are No. 11 gauge.

Mesh Fences

Mesh fences, such as horse-no-climb, may be used for confinement fencing in corrals, feed lots, and small acreage areas. No-climb types of configurations are used for camelids and horses to prevent fence damage and potential injury to the animal.

Attachment of Wires

WIRE ATTACHMENT TO ANCHOR POSTS

All fence wires shall be securely attached to the anchor posts at the both ends of each section of fence. Wires shall be stretched using a dummy post or other suitable and safe means to stretch the wires to the anchor post until they can be secured. Wires shall be double wrapped around the anchor post, and then twisted back on the stretched line with at least six tight wraps. The wires shall also be stapled to wooden anchor posts.

[pic]

Wire Attachment to Line Posts

Fence wires shall be attached to all line posts and stays using staples, tie wires, or manufactured wire fasteners of good quality.

Tie wires for attaching standard fence wires to line posts and stays shall be 16 gauge or heavier galvanized steel.

Staples shall be 9 gauge galvanized or polished hard wire, 1.75 inches long for softwood, and 1 inch long for hardwood posts. Staples shall be driven diagonally to the grain at a slightly downward angle. The staples on line posts shall be driven such that they do not bind or bend the fence wire, allowing the fence wire to contract and expand.

Wire Attachment for Suspension Fences

Suspension fences are designed to have a whip-like action to turn back livestock. Suspension fence wires shall be tight, with not more than a 3 inch sag between the line posts.

Fence wires in suspension fence line sections shall be attached to wooden line posts such that they can slide back and forth. Any suitable wire fastener showing good workmanship may be used. 20 gauge sheet metal 1 inch x 1/2 inch, fastened on each side of the wire with a sixpenny nail works well.

Steel “T” or “U” line posts have enough give that wires can be attached normally for suspension fences.

Wire Attachment for Let Down Sections

For stay type let down fences, the fence wires are attached to stays located at the line post. The stays are held to the line posts using 9 gauge wire loops, wrapped around the top and bottom of the line posts and stays. The loops are stapled or tied to the line post to hold them in place. The fence is let down by lifting the top loops off of the top of the stays.

[pic]

Staple key attachment may also be used to attach the wires to the line posts for let down sections.

[pic]

Fence Anchors

FENCE ANCHORS SHALL BE INSTALLED WHEN THE BOTTOM WIRE IS MORE THAN 6” ABOVE THE DESIGN HEIGHT ABOVE GROUND.

[pic]

[pic]

Anchor weights for holding down fence wires crossing drainages or depressions shall weigh at least 50 pounds or be equivalent to a 1 cubic foot concrete block. They shall be attached with 9 gauge or heavier smooth wire.

Fence wires can also be held down with a line post set in concrete. The post shall be set in a hole 2.5 feet and 12 inches in diameter.

Water Gaps

WHERE THE FENCE CROSSES A DRAINAGE MORE THAN 40 FEET WIDE, END BRACING SHALL BE INSTALLED ON EACH SIDE OF THE DRAINAGE. WATER GAP FENCE SECTIONS MATERIALS SHALL EQUAL THE QUALITY OF THE ADJOINING FENCE. THEY SHALL BE ASSEMBLED AS A SEPARATE UNIT TO PROTECT THE MAIN FENCE FROM DAMAGE. THE ENDS OF THE WATER GAP FENCE WIRES SHALL BE ATTACHED TO A SEPARATE STEEL OR WOODEN LINE POST, THAT IS ATTACHED TO THE END POSTS USING LIGHTWEIGHT WIRE OR STAPLES THAT CAN BREAK AWAY WITHOUT DAMAGING THE END BRACES IF DEBRIS GETS TRAPPED AGAINST THE WATER GAP.

[pic]

For deep narrow drainages, a separate fence section can be installed below the main fence. This separate fence section shall not be attached to the main fence.

[pic]

Gates

GATES SHALL EQUAL OR EXCEED THE QUALITY OF THE ADJOINING FENCE. THEY MAY BE MADE OF WOOD, ALUMINUM, STEEL, OR WIRE.

If a heavy gate is attached to the anchor post side of the end brace assembly, an additional tension wire running in the opposite direction, from 4 inches above the horizontal brace on the anchor post to the bottom of the brace post, shall be installed. This tension wire should only be tightened enough to offset the weight of the gate.

Wire gates shall be constructed with equal or better quality wire and posts as used in the fence. Wire gates across roads shall have stays at least every 3 feet to ensure they are visible to vehicles. They shall be secured to the end brace assemblies with smooth 9 gauge galvanized wire, or fence wire.
