Featured product: Flap gates
------------------------------------------------------

Among the few items of water-related equipment that almost everyone has 
seen is the simple flap gate -- usually in quiet service discharging 
stormwater into a lake, river, or stream, or releasing treated 
wastewater back into the natural environment after it's been processed 
through a municipal wastewater-treatment facility.

But all flap gates are not created equal: While cast iron has been the 
predominant material used for many years, it's being eclipsed by 
stainless steel and aluminum, and for good reason. Cast iron is becoming 
increasingly difficult to obtain from reliable domestic producers, 
particularly as demand for cast iron increases in China and elsewhere. 
Some manufacturers have tried substituting cast iron from international 
sources, only to find that they're receiving a much lower-quality 
product than they expected.

While cast iron has been having troubles, stainless steel and aluminum 
have been on a hot streak. Both materials can be fabricated in ways that 
allow them to be stronger and lighter than cast iron. Cast iron takes 
its strength from sheer mass; stainless steel and aluminum, by contrast, 
take their strength from structural design, delivering a stronger gate 
with less metal. That makes fabricated flap gates easier to mount and 
install than comparable cast iron gates, among other advantages. And the 
difference between a stainless steel gate and a cast iron gate in terms 
of reliability and corrosion resistance is significant.

We're happy to offer fabricated flap gates for stormwater, water, and 
wastewater installations of all types. If you'd like to know more,
