Barbed wire is constructed conforming to ASTM A121 Class II Aluminuminum-coated, 12.5 gauge wire with 14 gauge, round, 4-point barbs spaced no more than 125 mm apart.

Tension Wire
线使用与给定类型的关系of fabric shall be of the same material and coating weight identified with the fabric type. Tension wire shall be 7-gauge marcelled steel wire with the same coating as the fabric type and shall conform to ASTM A824. Material conforming to FS RR-F-191/4.

Each roll of mesh fabric carries a tag showing the kind of base metal (steel, Aluminuminum, or Aluminuminum alloy number), kind of coating, the gauge of the wire, the length of fencing in the roll, and the name of the manufacturer. Posts, wire, and other fittings are identified as to manufacturer, kind of base material (steel, Aluminuminum, or Aluminuminum alloy number), and kind of coating.


Gate Assembly
质量符合ASTM F900和/或ASTM F1184。Gate frames conforming to strength and coating requirements of ASTM F1083. Gate frames conforming to strength and coating requirements of ASTM F1043. Gate fabric the same specified for chain link fabric.

Gate Leaves
For gate leaves, more than 2.44 m wide, we provide intermediate members and diagonal truss rods or tubular members as necessary to provide rigid construction, free from sag or twist.
Gate leaves less than 2.44 m wide, truss rods or intermediate braces are supplied.
Intermediate braces supplied on all gate frames with an electro-mechanical lock.

Hardware and Accessories are supplied for furnishing and installing latches, hinges, stops, keepers, rollers, and other hardware items as required for the operation of the gate.
For high security applications, each end member of gate frames is extended sufficiently above the top member to carry three strands of barbed wire in horizontal alignment with barbed wire strands on the fence.

For sliding gates. Electrical gate operators have a right angle gearhead instantly reversing motor with magnetic drum-type brake, friction disc clutch, reversing starter with thermal overload protection, and a chain-driven geared rotary-type automatic limit switch. Gears consist of a hardened steel machine cut worm and mating bronze gear. All gears and bearings shall operate in a bath of oil. Gate operators are equipped with emergency release mechanism.

Electro-mechanical locking devices for sliding gates and personnel gates shall be solenoid actuated such that the deadbolt retracts when the solenoid is energized and remains electrically retracted until the gate is closed. Provide continuous duty type solenoid, rated for 120V ac, 60Hz operation. The locking device shall be unlockable by key and keyed on both sides. Status of the electro-mechanical lock shall be monitored by two limit switches (integral to the locking device) wired in series. One switch shall monitor the deadlock lever and the other monitor the locking tongue.


Installation conforming to ASTM F567.

Site clearing before installation:
Area on either side of the fence line shall be cleared to the extent indicated.
Space line posts equidistant at intervals not exceeding 3 m.
Terminal (corner, gate, and pull) posts shall be set at abrupt changes in vertical and horizontal alignment.

Excavation Clear all post holes of loose material. Spread waste material where directed. Eliminate ground surface irregularities along the fence line to the extent necessary to maintain a 25 mm clearance between the bottom of the fabric and finish grade.

All posts are set in concrete at the required dimension and depth and at the set spacing.
Posts should be spaced not more than 3 m apart and should be set at a minimum of 1 m in concrete footings. The post holes shall be in proper alignment so that there is a minimum of 75 mm of concrete on all sides of the posts. The concrete shall be thoroughly compacted around the posts by vibrating and shall have a smooth finish slightly higher than the ground and sloped to drain away from the posts. All posts shall be set plumb and to the required grade and alignment. No materials shall be installed on the posts, nor shall the posts be disturbed in any manner within seven (7) days after the individual post footing is completed. Should rock be encountered at a depth less than the planned footing depth, a hole shall be filled with grout, composed of one part Portland cement and two parts mortar sand. Any remaining space above the rock shall be filled with concrete in the manner described above. In lieu of drilling, the rock may be excavated to the required footing depth. No extra compensation shall be made for rock excavation.

Horizontal brace rails, with diagonal truss rods and turnbuckles, shall be installed at all terminal posts.

a. Install chain link fabric on the side of the post indicated. Attach fabric to terminal posts with stretcher bars and tension bands. Space bands at approximately 381 mm intervals. Install fabric and pull taut to provide a smooth and uniform appearance free from sag, without permanently distorting the fabric diamond or reducing the fabric height. Fasten fabric to line posts at approximately 381 mm intervals and fastened to all rails and tension wires at approximately 610 mm intervals.
b. Cut fabric by untwisting and removing pickets. Accomplish splicing by weaving a single picket into the ends of the rolls to be joined. The bottom of the installed fabric shall be 50 mm plus or minus 13 mm above the ground.
c. After the fabric installation is complete, exercise the fabric by applying a 222 newtons push-pull force at the center of the fabric between posts; the use of a 133 newtons pull at the center of the panel shall cause fabric deflection of not more than 63.5 mm when pulling fabric from the post side of the fence; every second fence panel shall meet this requirement; resecure and retest all failed panels at the Contractor's expense.

Install barbed wire supporting arms and barbed wire as indicated on the drawings and as recommended by the manufacturer. Anchor supporting arms to the posts in a manner to prevent easy removal with hand tools. Pull barbed wire taut and attach to the arms with clips or other means that will prevent easy removal.

a. Install gates at the locations shown. Mount gates to swing as indicated. Install latches, stops, and keepers as required. Install gates as recommended by the manufacturer.
c. Submit 6 copies of operating and maintenance instructions, a minimum of 2 weeks prior to field training. Operating instructions shall outline the step-by-step procedures required for system startup, operation, and shutdown. Include the manufacturer's name, model number, service manual, parts list, and brief description of all equipment and their basic operating features. Include in the maintenance instructions routine maintenance procedures, possible breakdowns and repairs, and troubleshooting guide. Also include the general gate layout, equipment layout and simplified wiring and control diagrams of the system as installed.

Ground fencing as specified. Electrical ground shall be constructed where a power line passes over the fence at 150 m intervals. The ground shall be installed directly below the point of crossing. The ground shall be accomplished with a copper clad rod 2.5 m long and a minimum of 19 mm in diameter driven vertically until the top is 152 mm below the ground surface. A No. 6 solid copper conductor shall be clamped to the rod and to the fence in such a manner that each element of the fence is grounded. Installation of ground rods shall not constitute a pay item and shall be considered incidental to fence construction. The Contractor shall comply with FAA-STD-019, paragraph when fencing is adjacent to FAA facilities.
