Unlock the full potential of your custom sheet metal parts with the correct bare metal finish.
While powder coating is a popular choice for aesthetics, bare metal finishes offer both functional and cosmetic benefits for sheet metal fabrication and CNC machining. In this video, we showcase the different bare metal options available at Protocase and ProtoSpace Mfg, and explain how to choose the right one for your specific application.
In this video, you’ll learn about:
No Finish / Stock Finish: The most economical choice for internal or functional parts where cosmetic perfection isn’t required.
Grained Finish: A sleek, brushed linear texture ideal for front panels and high-visibility enclosures.
Vibratory Finish: A non-directional, tumbled finish that smooths edges and minimizes CNC tool marks.
Media Blasting: A premium glass-bead process that creates a uniform, matte, and non-reflective surface.
