B. The manufactured framework shall be subjected to the Ameristar thermal stratification coating process (high - temperature, in -line, multi- stage, and multi - layer) including, as a minimum, a six -stage pretreatment/wash and an electrostatic spray application of a polyester finish. The topcoat shall be a "no -mar" TGIC polyester powder coat finish with a minimum thickness of 2 mils (0.0508mm). The color shall be (specify Black. Bronze, White or Desert Sand). The stratification- coated framework shall be capable of meeting the performance requirements for each quality characteristic shown in Table 2. C. Material for fence pickets shall be 1" square x 0.062" thick extruded tubing. The cross - sectional shape of the rails shall conform to the manufacturer's ForeltunnerTM design with outside cross - section dimensions of 1.75" square. The top wall and internal web of the of the rail shall be 0.070" thick; the sidewalls shall be 0.070" thick for superior vertical load strength. Picket holes in the ForeRunner rail shall be spaced 4.715" o.c., except for Invincible style 6' long, which shall be, spaced 4.98" o.c. Picket retaining rods shall be 0.125" diameter galvanized steel. Fence posts and gate posts shall meet the minimum size requirements of Table 1. High quality PVC grommets shall be supplied to seal all picket -to -rail intersections. D. All fasteners shall be stainless steel. Bracket to rail attachments shall be made using specially designed one -way tamperproof security bolts with inverted "t- nuts ". Bracket to post connections shall be made using self - drilling hex -head screws. E. Aluminum castings shall be used for all rings, post caps, finials, and miscellaneous adornments. 2.03 FABRICATION A. Pickets, rails and posts shall be pre -cut to specified lengths. ForeRunner rails shall be pre - punched to accept pickets. B. The rail inner slide shall be fully inserted into the rail outer channel to form the raceway for the internal retaining rod. Grommets shall be inserted into the pre - punched holes in the rails, and pickets shall be inserted through the grommets so that pre - drilled picket holes align with the internal raceway of the two -part ForeRunner rails. (Note: This can best be accomplished by using an alignment template). Retaining rods shall be inserted into each ForeRunner rail so that they pass through the pre - drilled holes in each picket, thus completing the panel assembly. C. Completed panels shall be capable of supporting a 300 lb. load (applied at midspan) without permanent deformation. Panels shall be biasable to a 25% change in grade. D. Gates shall be fabricated using 1.75" sq. reinforced ForeRunner rail material, 1.75" sq. x .250" gate ends, and 1" sq. x .125" pickets. All rail and upright intersections shall be joined by welding. All picket and rail intersections shall be joined by welding. PART 3- EXECUTION 3.01 PREPARATION All new installation shall be laid out by the contractor in accordance with the construction plans. 3.02 FENCE INSTALLATION Fence post shall be spaced according to Table 3, plus or minus % ". For installations that must be raked to follow sloping grades, the post spacing dimension must be measured along the grade. Fence panels shall be attached to posts with brackets supplied by the manufacturer. Posts shall be set in concrete footers having a minimum depth of 36" (Note: In some cases, local restrictions of freezing weather conditions may require a greater depth). The "Earthwork" and "Concrete" sections of this specification shall govern material requirements for the concrete footer. Posts setting by other methods such as plated posts or grouted core - drilled footers are permissible only if shown by engineering analysis to be sufficient in strength for the intended application. 3.03 FENCE INSTALLATION MAINTENANCE When cutting/drilling rails or posts adhere to the following steps to seal the exposed surfaces; 1) Remove all metal shavings from cut area. 2) Apply custom finish paint matching fence color. Failure to seal exposed surfaces per steps 1& 2 above will negate warranty. Ameristar spray cans or paint pens shall be used to prime and finish exposed surfaces; it is recommended that paint pens be used to prevent overspray. Use of non - Ameristar parts or components will negate the manufactures' warranty. 3.04 GATE INSTALLATION Gate posts shall be spaced according to the manufacturers' gate drawings, dependent on standard out -to -out gate leaf dimensions and gate hardware selected. Type and quantity of gate hinges shall be based on the application; weight, height, and number of gate cycles. The manufacturers' gate drawings shall identify the necessary gate hardware required for the application. Gate hardware shall be provided by the manufacture of the gate and shall be installed per manufacturer's recommendations. 3.05 CLEANING The contractor shall clean the jobsite of excess materials; post -hole excavations shall be scattered uniformly away from posts.
