PART 2 - MATERIALS
2.01 MANUFACTURER
The fence system shall conform to (specify Montage Commercial standard picket space or Montage Commercial Pool, Pet & Play 3”
air space) Welded and Rackable (ATF – All Terrain Flexibility) Ornamental Steel, (for standard picket space, specify Classic, Majestic,
Genesis, or Invincible; for 3” air space, specify Classic, Majestic, or Genesis) design, (specify extended picket or flush) bottom rail
treatment, (specify 3-Rail, 4-Rail, or 3-Rail with Double Rings, 4-Rail with Double Rings) style manufactured by Ameristar Fence
Products, Inc., in Tulsa, Oklahoma.
2.02 MATERIAL
A. Steel material for fence panels and posts shall conform to the requirements of ASTM A653/A653M, with a minimum yield
strength of 45,000 psi (310 MPa) and a minimum zinc (hot-dip galvanized) coating weight of 0.60 oz/ft2 (184 g/m2), Coating
Designation G-60.
B. Material for pickets shall be 3/4” square x 14 Ga. tubing. The rails shall be steel channel, 1.5” x 1.4375” x 14 Ga. Picket holes in
the rail shall be spaced (specify 4.675” o.c. for standard picket space or 3.500” o.c. for 3” air space). Fence posts and gate posts shall
meet the minimum size requirements of Table 1.
2.03 FABRICATION
A. Pickets, rails and posts shall be pre-cut to specified lengths. Rails shall be pre-punched to accept pickets.
B. Pickets shall be inserted into the pre-punched holes in the rails and shall be aligned to standard spacing using a specially
calibrated alignment fixture. The aligned pickets and rails shall be joined at each picket-to-rail intersection by Ameristar’s proprietary
fusion welding process, thus completing the rigid panel assembly (Note: The process produces a virtually seamless, spatter-free
good-neighbor appearance, equally attractive from either side of the panel).
C. The manufactured panels and posts shall be subjected to an inline electrode position coating (E-Coat) process consisting of a
multi-stage pretreatment/wash, followed by a duplex application of an epoxy primer and an acrylic topcoat. The minimum
cumulative coating thickness of epoxy and acrylic shall be 2 mils (0.058 mm). The color shall be (specify Black or Bronze). The
coated panels and posts shall be capable of meeting the performance requirements for each quality characteristic shown in Table 2
(Note: The requirements in Table 2 meet or exceed the coating performance criteria of ASTM F2408).
D. The manufactured fence system shall be capable of meeting the vertical load, horizontal load, and infill performance requirements
for Commercial weight fences under ASTM F2408.
E. Gates with an out-to-out leaf dimension less than and including 72 inches shall be fabricated using Montage Commercial
ornamental panel material and 1-3/4” sq. x 14ga. gate ends. Gate leafs greater than 72 inches shall be fabricated using ForeRunner
rails, intermediate uprights, gussets and 1-3/4” sq. x 14ga. gate ends. All rail and upright intersections shall be joined by welding. All
picket and rail intersections shall also 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 INSTALLATION
Fence post shall be spaced according to Table 3, plus or minus 1/4”. 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 steel surfaces; 1) Remove all metal shavings
from cut area. 2) Apply zinc-rich primer to thoroughly cover cut edge and/or drilled hole; let dry. 3) Apply 2 coats of custom finish
paint matching fence color. Failure to seal exposed surfaces per steps 1-3 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.

Montage Commercial Specification Ameristar Perimeter Security USA Inc. Rev. 12/08/2022
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.
