NRG heavy
duty fiberglass SuperFlights™ , pultruded with an isophthalic
polyester resin, are the lightweight corrosion resistant choice over
old-fashioned, buoyant wood flights. Reinforced transversely and laterally
with unidirectional glass roving and a continuous fiberglass strand
mat, it is its high Modulus of Elasticity which gives the SuperFlight
the least amount of deflection of any c-channel or L-shaped fiberglass
flight on the market today!
Unlike flange ended profile flights that retain sludge, NRG's open
ended c-channel SuperFlights do not recirculate solids into the effluent.
NRG's SuperFlights have an integral scraping lip for optimizing tank
scraping, and can be drilled and notched in our factory for ease of
assembly with NRG's polypropylene filler blocks, UHMW-PE wear shoes,
and F22 attachment paddles. NRG SuperFlights can be retrofitted to
replace redwood flights or existing fiberglass c-channel, sigma-shaped,
or l-shaped designs. |
