The POLYCAST(R) 700 Series offers
exceptional impact resistance. Designed for extreme loads, the HARDNOSETM
cast iron frame strengthens the grating and drain assembly for extra durability.
The POLYCAST(R) 700 Series is recommended
for heavy commercial and military aircraft taxi ways at moderate speeds,
hard wheel forklifts, pallet jacks, solid wheel carts, construction equipment,
and off-road vehicles. It meets FAA Airport pavement design loads
per AC 150/5320-6D.
The flow rates are comparable to the conventional 600 Series (840 GPM).
Grating hold down devices are provided and should be maintained
secure to prevent grate movement during loading. Optional anchoring
bolts are available.
The 700 Series assembly consists of HARDNOSETM
cast iron frames inlaid
on the top of the conventional 600 Series Polymer Concrete Channel and
fitted with Cast Iron Grates (DG0641). |
