 The
POLYCAST® 900
Series Grated Line Drain
900
Series Grated Line Drain for Highway and Airport Drainage Systems collects
runoff before it travels onto road or airplane taxi surfaces where
water and ice can cause hazardous conditions. POLYCAST® Grated Line
Drain exceeds AASHTO highway standards for vehicles operating at highway
speeds. It is a safe, economical, and low maintenance solution for roadway
(DOT) surface drainage systems.
The POLYCAST® Grated Line Drain features:
- Flow rates of up to 470 GPM per outlet
- Corrosion, chemical and UV resistant polymer concrete channels
- Integral embedment anchor flanges secure the non-removable grate
to prevent pullout from high-speed highway traffic
- Removable grates with locking devices also available
- Coefficient of thermal expansion similar to concrete
The Grated Line Drain assembly consists of
a one-piece, integral cast iron frame and grate on top of the conventional
600 Series polymer concrete channel. Each 16” frame has four
integral concrete anchors for maximum pullout resistance. Exceeds
the following ASTM specifications: C307, C579, C580, C140, C267,
C666 and B117.
 3000 Series Grated Line
Drain
POLYCAST® 3000 is a high capacity presloped drain system designed
for airports, roadways and other applications needing high volume flow
rates. The unique bulb shaped design, combined with the continuous
1% slope, provides the largest flow capacity of any similar presloped
trench drain on the market today. The flow rates for POLYCAST® 3000
are more than 3000 GPM (gallons per minute) or 6.73 cfs (cubic feet
per second) for 120' of drain. Competitive drain systems often require
extender panels for comparable flowrates.
The system channels are manufactured using the pultrusion process
to produce a lightweight, high strength fiber reinforced polymer composite
channel. The polymer material limits water absorption to less than
1% and provides excellent chemical resistance. The pultruded fiberglass
construction provides extremely strong vertical sidewalls. This reduces
sidewall deflection during the concrete pour and maintains maximum
flow capacity. The sidewalls of many other drain systems tend to collapse
during this critical process, resulting in substantially reduced flows.
The coefficient of thermal expansion for POLYCAST® 3000 (4.5 x
10-6 in/in/°F) is similar to that of concrete (6 x 10-6 in/in/°F)
so it will not buckle or break apart from thermal expansion stresses.
This ensures that the structural integrity of the channel side walls
and the flow rates remain constant. These basic design considerations
reduce the need for special parts inventory and expensive accessories.
