All gates welded
first and then polyester powder coated after fabrication. Types of gate
available: Single, double drive, cantilever, overhead, and rolling. Gate
operators can be installed on all gates. Types if hinges and latches are
furnished according to gate size and usage.
HARDWARE (BALL TOPS,
BRACKETS, FINALS AND SCROLLS)
All hardware shall be zinc alloy
die cast AG40-A as per ASTM B86 with a tensile strength of 41,000 psi
(282 Mpa) and a Brinell hardness of 82, or malleable iron hot dipped
galvanized prior to powder coating.
ASSEMBLY
Sections and
gates shall be factory-assembled with pickets welded or riveted to the
rails using a ¼ “ (6.35 mm) industrial rivet #381080691. Posts shall be
predrilled and routed to receive the horizontal rails. The rails
brackets (when needed) shall be attached by ¼” (6.35 mm) screws. Ball
tops, brackets, finials, and scrolls shall be factory assembled. Racked
and radius sections are also factory-assembled.
FINISH
All components
shall go through a five-stage process: 1) Rinsed and cleaned with clear
water 2) Phosphate treated to etch the surface 3) Rinsed again with
water 4) Components are oven-dried prior to powder coating 5) Polyester
powder is then applied by the electrostatic spray process to a thickness
of 2.5 mils (.0635 mm). The metal is then oven-backed at 450o (232o C)
for 14 minutes. Standard colors available: Black, Chocolate, Ensor
Green, and White. Custom colors are available upon request.
