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.
ASSEMBLY
Sections and
gates shall be factory-assembled with pickets welded or screwed using a
#6 1dacrotized screw. 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
clear 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.
