extrusion process are specified in the approved quality
control documentation. The railing components are
available in a white, black, bronze, or custom powder
coated finish.
3.1.4 Aluminum Railing System with Stanchions
The Aluminum Railing System can be supported to the
substrate with stanchions into 2-inch (50.8 mm) square
aluminum posts in lieu of post base plates and consists of
guard components as described in Section 3.1.1. The
stanchions are produced from extruded 6005A-T5
aluminum alloy.
The minimum yield and tensile strengths, minimum
thickness of the railing components, and manufacturing
extrusion process are specified in the approved quality
control documentation. The railing components are
available in a white, black, bronze, or custom powder
coated finish.
3.2 Guard:
3.2.1 Aluminum Railing System:
The height of the railing assembly is 42 inches
(1067 mm) above the walking surface. The top rail
cover has a wall thickness of 0.055-inch (1.40 mm);
and depending on the top rail series, the overall top
rail width ranges from 2-inches (50.8 mm) minimum
to 2 ½-inches (63.5 mm) maximum, and the overall
top rail depth ranges from 1.83-inches (46.5 mm)
minimum to 2.35-inches (59.7 mm) maximum. The bottom
rail cover has a wall thickness of 0.055-inch
(1.40 mm), a width of 1½-inches (38.1 mm), and a depth
of 1½-inches (38.1 mm). For the sub-rail
panels, both top and bottom h-channel rails having a

and 0.083-inch (2.11 mm) thick, a width of 1.38-inches
(35.1 mm), and a depth of 0.97-inch (24.6 mm). Both top
and bottom rail covers and sub-rail panels are available in
6-foot (1.83 m) and 8-foot (2.44 m) lengths. They are
produced from 6063-T5 aluminum alloy and come in a
powder coated finish. The maximum railing span for each
Aluminum Railing System series is noted in
Table 1.
The pickets are hollow rectangular extruded 6063-T5
aluminum. The pickets have a wall thickness of
0.050-inch (1.27 mm), a width of ½-inch (12.7 mm), and
a depth of ¾-inch (19.1 mm) and come in a powder coated
finish. Each picket is inserted in the pre-punched holes on
the top and bottom h-channel rails of each
sub-rail panel, with a center-to-center spacing of
4 ½-inches (114.3 mm).
The posts come in either 2-inches (50.8 mm) square
hollow extruded 6005A-T5 aluminum with a wall thickness
of 0.090-inch (2.28 mm) or 3-inches (76.2 mm) square
hollow extruded 6005A-T5 aluminum with a wall thickness
of 0.065-inch (1.65 mm); and both come in a powder
coated finish. The optional post sleeve comes in 4-inches
(101.6 mm) square hollow extruded 6063-T5 aluminum
with a wall thickness of 0.080-inch (2.03 mm) and come
in a powder coated finish. The post cap is produced from
A380 aluminum alloy and is installed at the top of the
extruded post and measures either
3-inches by 3-inches (76.2 mm by 76.2 mm) square or
4-inches by 4-inches (101.6 mm by 101.6mm) square.
The post base plate is produced from A369 aluminum
alloy and is installed at the bottom of the extruded post; it
comes in either a 4.02-inches (102.1 mm) by
4.02 inches (102.1) square for the 2-inches (50.8 mm)
square post or 4.99-inches (126.7 mm) by 4.99-inches
(126.7 mm) square for the 3-inches (76.2 mm) square
post. Each post base comes in a powder coated finish.
The 6-foot (1.83 m) and 8-foot (2.44 m) railing systems
utilize one intermediate bottom rail support leg located at
the midspan. Each support leg is a 1½-inches (38.1 mm)
square hollow extruded 6063-T5 aluminum with a wall
thickness of 0.052-inch (1.32 mm) and comes in a powder
coated finish.
The top and bottom rail connector clips are made
from 0.080-inch (2.03 mm) thick 5052-H32 aluminum
sheets and measures 1-inch (25.4 mm) wide by
0.94-inch (23.9 mm) long by 0.060-inch (1.52 mm) deep,
with two 0.16-inch (4.06 mm) diameter holes for securing
into the post.
See Figure 1 for details of the components for the
aluminum railing system.

(8.4 mm) diameter hole in each leg. The holes can secure
the post to the bracket and bracket to supporting
substrate. See Figure 5 for component details.
The fascia bracket is made from 0.25-inch (6.4 mm)
thick 5032-H32 aluminum sheets and measures
3.29-inches (83.5 mm) wide by 5.64-inches (143 mm)
long by 6-inches (152.4 mm) in length. The sides have
four 0.271-inch (6.9 mm) diameter holes for securing the
post to the bracket. The lips have four 0.321-inch
(8.2 mm) diameter holes for securing into the supporting
substrate. See Figure 6 for component details.
