Hard freeze

February 1, 2022

One of the advantages of stainless steel as a material for slide gates is that it stands up well to tough conditions -- like when a basin freezes. It's better never to let the water freeze at all, but if there's any chance of it, stainless steel has a decided advantage over cast iron or fiberglass. (Remember: Water expands when it turns into ice. Expanding ice can crack fiberglass, and once cracks develop, the FRP gate itself is going to need repair.) We decided to wait for warmer weather to perform any further inspections on this one.
