Smooth Arc Mfg.

Concrete Accessories

Smooth Arc began in 2016 because the business owner saw an area
under the overhead doors that was completely unprotected by insulation
and set about to find a solution to stop the heat from exiting under the
door. With some research and input from local contractors, Smooth Arc
came up with the ideal solution. Allowing us to introduce to you the

about troweling in the angle for water run off.
