Featured product: Stainless steel sluice gates
------------------------------------------------------

For decades, cast iron was the only material allowed by AWWA standards 
for big sluice gates -- but refinements in design and improvements in 
material availability have made other materials not only competitive 
with, but truly superior to, cast iron.

Cast iron gates obtained their strength from their sheer bulk. Stainless 
steel sluice gates, by contrast, gain their strength by virtue of their 
structural design.  This means stainless steel gates can be built much 
lighter than comparable cast iron gates. This results in 
better-performing gates that are easier and more economical to install.

Moreover, stainless steel gates make no metal-to-metal contact at the 
seating perimeter; instead, the stainless steel plate is channeled by 
UHMW (ultra-high molecular weight) polyethylene guides, which reduces 
the amount of friction encountered when the gates are raised and lowered 
and improves the quality of the seal. As a result, stainless steel gates 
can be guaranteed to out-perform the leakage rates allowed by AWWA 
standards for cast iron gates -- in some cases, by a factor of ten or 
more. Plus, stainless steel gates don't seize like cast iron gates do.
