Unless otherwise indicated, fabric height shall be as shown on the drawings or as specified herein. Fence framework members are available using different shapes and sections. For reasons of strength and appearance, this specification requires the use of square sections. Alternate shapes may be considered if submitted for approval within ten days before bid date and are accompanied by strength calculations indicating equal or superior characteristics to those specified. Bending strength, zinc coating, appearance, and longevity must be equal to or greater than those of the products specified, in order to be considered as an acceptable alternate. All posts, rails and fittings shall be coated with 10 to 15 mils of PVC. Color to be selected by Owner/Architect from the manufacturers standard colors.


A. POSTS – INTERMEDIATE, shall be 1-½ " square tube steel weighing 2.49 lbs./lin ft for fences 5’ high or less. Intermediate posts for fences 6’ or higher shall be 2" square tube steel 3.07 lbs. / lin. ft. Weight of zinc shall be 2.0-oz./sq. ft. Posts shall be coated with 10 to 15 mils of PVC.


B. POSTS – TERMINAL (End, Corner and Pull), shall be 2-½" square tube steel weighing at least 3.98 pounds per lineal foot and shall have a 2.0 oz. /sq. ft. zinc coating minimum and shall have moisture proof post caps with acorn type design. Posts shall be coated with 10 to 15 mils of PVC.


C. POSTS – GATE: For swing gates shall be in accordance with the following schedule:

D. TOP RAIL: Top rail shall be 1-1/2" square tube steel galvanized weighing 1.60 pounds per lineal foot. Top rail to pass through line post cap and form a continuous brace between terminal posts. All rails shall be coated with 10 to 15 mils of PVC.


E. BRACE RAILS – Brace rail shall be 1-1/2" galvanized square tube steel weighing 1.6 pounds per lineal foot. Brace rails to be located at all terminal and gate posts and equipped with a 3/8" diameter truss rod and turnbuckle. Fences 12’ high or more shall have a continuous center brace rail.


F. TENSION WIRE – shall be 7-gauge coil spring wire located at top (in lieu of toprail, when specifically shown on drawings) and bottom of fabric, and shall be PVC coated to match the fabric. Top wire shall pass through the barb arm on the line post.


G. BARBED WIRE – (where required) shall be "HI-SECURITY" consisting of two strands of twisted wire, 12-1/2 gauge, with 4-point barbs of 14 gauge wire on 3" spacing. Barbed wire shall be galvanized and conform to ASTM A-121, chain link fence grade. Barbed wire supporting arms on line posts shall be at an angle of approximately 45 degrees or vertical, as required, and shall be of sufficient strength to withstand a 250 lb. Load applied at the outer strand.


H. FABRIC: Chain link fabric shall be PVC coated galvanized steel. PVC shall be applied by the thermal fusion bonded process in accordance with ASTM F-668, Class 2b. The steel core wire shall be 9 gauge, coated with .30 oz./sq.ft. of zinc and have a minimum breaking strength of 1290 pounds. Fabric shall be woven in a 2" mesh and both selvages shall be knuckled.


I. FABRIC LOCKS: To prevent easy removal and for other security reasons, fabric shall be attached to all line posts and horizontal rails with stainless steel "HI-SECURITY" locks shot into place with the appropriate gun and powder charge at intervals not exceeding 15" on the posts and 24" on the horizontal rails. These locks shall consist of the following:
