Smith Built produces R- Panel in 20 different colors. All of our paint systems include a 40 year limited warranty for guaranteed durability.


As R-Panel is typically installed over metal purlins or hat channel, Smith Built provides color-matched self-drilling fasteners to secure the panels to the structural steel elements. We also carry a wide array of structural steel for any project for which R-Panel is a fit.
