Belzona® Coats Filter Screens For A Hydro Dam



Power (POWR)




Customer Location:

Red Rock Hydroelectric Dam Iowa


Application Date:



Application Situation:

Filter Screens for a Hydroelectric Dam that is being built were coated by Belzona Great Lakes in Toronto. The gates were then shipped to Iowa where they would be installed and in service.



Filter Screens filter debris sizes from the river to acceptable size that can go into the Hydro-power energy production process. Corrosion and impact from sedimentary debris deteriorated the gates over time letting in debris size hazards to the process and equipment.



Belzona 5811



Carbon Steel


Application Method:

Spray Applied airless plural component sprayer and brush applied in edges.


Belzona Facts:

Belzona 5811 was great preventive coating against corrosion to keep the integrity of the gates in tact over years so larger size debris won't get in that could damage the machinery. This damage could cost future tens of thousands of dollars in machine repair/replacement costs and downtime.
