ST. BARBARA CATHOLIC SCHOOL TASK 2 75-24272-01 <br />DIOCESE OF ORANGE SEPTEMBER 12TH, 2024 <br />SANTA ANA, CA BID & PERMIT SET <br /> <br />DECORATIVE METAL FENCES AND GATES 323119 - 4 <br />F. Pickets, rails and posts shall be pre-cut to specified lengths. Rails shall be pre-punched to accept <br />pickets. <br />G. Pickets shall be inserted into the pre-punched holes in the rails and shall be aligned to standard <br />spacing using a specially calibrated alignment fixture. The aligned pickets and rails shall be <br />joined at each picket-to-rail intersection by Ameristar’s proprietary fusion welding process, thus <br />completing the rigid panel assembly. <br />H. The manufactured panels and posts shall be subjected to an inline electrodeposition coating (E- <br />Coat) process consisting of a multi-stage pretreatment/wash, followed by a duplex application <br />of an epoxy primer and an acrylic topcoat. The minimum cumulative coating thickness of <br />epoxy and acrylic shall be 2 mils (0.058 mm). The color shall be Black. The coated panels and <br />posts shall be capable of meeting the performance requirements for each quality characteristic <br />shown in Table 2: <br />I. <br />Table 2 – Coating Performance Requirements <br />Quality Characteristics ASTM Test Method Performance Requirements <br />Adhesion D3359 – Method B Adhesion (Retention of Coating) over 90% of <br />test area (Tape and knife test). <br />Corrosion Resistance B117, D714 & D1654 Corrosion Resistance over 1,500 hours <br />(Scribed per D1654; failure mode is accumu- <br />lation of 1/8” coating loss from scribe or me- <br />dium #8 blisters). <br />Impact Resistance D2794 Impact Resistance over 60 inch lb. (Forward <br />impact using 0.625” ball). <br />Weathering Resistance D822 D2244, D523 (60˚ <br />Method) <br />Weathering Resistance over 1,000 hours <br />(Failure mode is 60% loss of gloss or color <br />variance of more than 3 delta-E color units). <br />J. <br />K. The manufactured fence system shall be capable of meeting the vertical load, horizontal load, <br />and infill performance requirements for Industrial weight fences under ASTM F2408. <br />L. Swing gates shall be fabricated using 1.75” x 14ga Forerunner double channel rail, 2” sq. x <br />12ga. gate ends, and 1” sq. x 14ga. pickets. Gates that exceed 6’ in width will have a 1.75” sq. <br />x 14ga. intermediate upright. All rail and upright intersections shall be joined by welding. All <br />picket and rail intersections shall also be joined by welding. Gusset plates will be welded at <br />each upright to rail intersection. Cable kits will be provided for additional trussing for all gates <br />leaves over 6’. <br />M. Pedestrian swing gates shall be self-closing, having a gate leaf no larger than 48” width. <br />Integrated hinge-closer set (2 qty) shall be ADA compliant that shall include a variable speed <br />and final snap adjustment with compact design (no greater than 5” x 6” footprint). Hinge-closer <br />set (2 qty) shall be tested to a minimum of 500,000 cycles and capable of self -closing gates up <br />to a maximum gate weight of 260 lbs. and maximum weight load capacity of 1,500 lbs. Hinge- <br />closer device shall be externally mounted with tamper-resistant security fasteners, with full <br />range of adjustability, horizontal (.5” - 1.375”) and vertical (0 - .5”). Maintenance free hinge- <br />closer set shall be tested to operate in temperatures of negative 20 F to 200 F degrees, and <br />swings to negative 2 degrees to ensure reliable final lock engagement.
