Surface Roughness Chart: Understanding Surface Finish in Manufacturing
Surfaces in manufacturing applications must remain within desired roughness limits to ensure the optimum quality of parts. Surface finishing has …
Name | Description | Materials | Color | Texture | Price | Link |
As-machined | The standard finish for our parts, the “as machined” finish, has a surface roughness of 3.2 μm (126 μin), which removes sharp edges and deburs parts cleanly. | All materials | n/a | Stain | $ | / | |
Bead Blasting |
Bead blasting is the process of powerfully propelling, generally with high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities. |

Anodizing | Keeping our parts in the long term, our anodizing process resists corrosion and wear. It’s also an ideal surface treatment for painting and priming, and it looks great too. | Aluminum |

Electroplating | Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations. |

Polishing |
Ranging from Ra 0.8~Ra0.1, polishing processes use an abrasive material to rub the part’s surface to make the shine more less shiny, depending on your requirements.

Powder Coating |
Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm. |

Painting |
Painting involves spraying a layer of paint onto the surface of the part. Colors can be matched to a Pantone color number of the customer’s choosing, while finishes range from matte to gloss to metallic. |

Black Oxide |
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance. |

Alodine |
Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivates and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts. |

Part Marking |
Part marking is a cost-effective way to add logos or custom lettering to your designs and is often used for custom part tagging during full-scale production. |
