30、ated, Type A, with 12.5 gauge wire with 14 gauge, round, 4-point barbs spaced no more than 125 mm 5 inches apart.2.2 GATES*NOTE: Show type of gates on the drawings, including degree of swing required. In heavy use conditions overhead slide gates should be considered if clearances permit, because the
31、se gates require less maintenance and repair than cantilever gates. Ground level track and roller systems should be avoided in climates where snow and ice may accumulate. Recessed tracks should never be used in climates where the recess may fill with ice and snow. Where gates are to receive electric
32、 locks, the gate post foundations should be lowered to frost depth to help prevent misalignment of the lock components.*Provide gate type and swing shown conforming to ASTM F 900 and/or SECTION 32 31 26 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from I

Gate leaves more than 2.44 m 8 feet wide shall have either 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 8 feet
35、 wide shall have truss rods or intermediate braces. Provide intermediate braces on all gate frames with an electro-mechanical lock. Attach gate fabric to the gate frame by method standard with the manufacturer. Welding is not permitted. Furnish latches, hinges, stops, keepers, rollers, and other har
36、dware items as required for the operation of the gate. Arrange latches for padlocking so that the padlock will be accessible from both sides of the gate. Provide stops for holding the gates in the open position.2.3 POSTS2.3.1 Metal Posts for Farm Style FenceProvide metal posts conforming to ASTM A 7

Since compos
38、ite posts are non-conductive, fence grounding procedures need to be detailed where grounding of the fence is required.*Provide polyester resin reinforced line posts produced from unsaturated polyester resin reinforced with E-glass. Fill posts with an appropriate filler material to form a rigid struc
39、tural support member. The post shall meet the strength requirements of ASTM F 1043 for heavy industrial fencing. Protect posts from UV and moisture degradation by a protective veil impregnated with resin (0.2 to 0.3 mm 8 to 12 mil minimum) and an acrylic based (0.05 mm 2 mil minimum) coating system.
40、 Posts shall exhibit corrosion and ultraviolet resistance as demonstrated when exposed to accelerated environmental test chamber for not less than 3,600 hours. The post shall not show structural failure (i.e., less than 10% loss of strength) as a result of exposure to moisture. Test post coating sys
