We don’t provide Ra or surface roughness specifications for our materials at this time.
To provide the best value for parts, material suppliers can change and mill finishes may have varying surface roughness. If one of our finishing services is not added for sheet metal parts, your parts will ship with the mill finish. Please note that parts may have light scratches when they get to you.
Please note, if you prefer your parts with the mill finish, select No finish (fastest option) at the Add Finishing step of our instant pricing system before adding parts to your cart.
For questions about our specs, reach out to our Support team. We’re glad to help with your next project!
