Available surface finishing for Stainless Steel part
| Image | Capabilities | Description | Applicable to | Texture | Price |
|---|---|---|---|---|---|
 | As-machined | As machined means the parts without any surface treatment after they get off the machines. | All materials | n/a | None |
 | Sanding and Polishing | Polishing is a surface finishing process to create a smooth surface. With mechanical, chemical or electrochemical methods, polishing will reduce the surface roughness of the parts to get a bright and reflective surface. | All materials | Smooth, glossy finish | $$$$ |
 | Bead Blasting | Bead blasting use high speed jetted sand and iron shots to hit the surface of the workpiece. it will change the surface of part and improve the mechanical properties of part. | Aluminum, Stainless Steel, Steel, Brass, Copper | n/a | $ |
 | Powder Coating | Powder coating is a surface finishing process that adhere dry powder on the surface of a meatal part. | All metal materials | Glossy or Sand | $$$ |
 | Black Oxide | Black oxidation is a kind of chemical surface treatment. it is used for surface coating commonly because it can eliminate reflections. | Steel, Stainless Steel | Smooth, matte | $$$ |
 | Electroplating | Electroplating is the process of depositing a thin layer of metal matieral on metal substrate using electric current. | Aluminum, steel, stainless steel | Smooth, glossy finish | $$$ |
 | Brushing | The brushing finish process is a surface treatment method that uses abrasive material to form lines on the surface of metal parts to achieve distinctive textured appearance. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | $$ |
 | Marking | Marking is available in differnt types and different methods. | All materials | n/a | $$ |
