Polar Flex

PolarFlex is a front plow and underbody blade system.  PolarFlex’s unique features include 12” carbide blade sections surrounded by a casting of EPDM synthetic rubber pads, which absorb vibration, reducing wear on the driver and the truck and increasing the life of the carbide blade.  Because the rubber allows the blades to adjust to the worn road surface, it cleans better.  PolarFlex eliminates the use of plow shoes.  PolarFlex also reduces salt, sand and fuel use.  Environmentally friendly, you bet, all parts of the PolarFlex can be recycled.

This year reduce costs, take care of your employees and be environmentally friendly with PolarFlex, call your St. Regis Culvert Inc. manufacturers representative or click on link for more details.
