Material: Laser cut 0.25” HRPO steel Finishing: tumble finish drying Deets: tumbling works great… but leaving your parts to air dry can cause some issues- especially flash rust here in the south (thank you humidity). We deal with this by running our parts through a drying cycle; we use the same tumbler design, just instead of ceramic media we use corn cob or walnut shells. 15-minutes gets all the moisture off the parts and helps keep them rust free. 🤌🏼 Laser cut parts delivered to your door. #
