Introduction to Stainless Steel
Stainless steel is the low carbon steel that offers many properties that are sought after for industrial applications. Stainless steel typically contains a minimum of 10% chromium by weight.
The material properties associated with stainless steel have made it a popular metal within a broad range of industries, including construction, automotive, aerospace and more. Within these industries, Stainless steel is versatile and is an effective choice for many applications.

Surface Finishes for Your Choosing
| Name | Description | Materials | Color | Texture | |
| Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Stain | |
Bead Blasting | Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments. | ABS, Aluminum, Brass, Stainless Steel, Steel | n/a | Matte | |
| Powder Coating | Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. | Aluminum | Black, any RAL code or Pantone number | Gloss or semi-gloss | |
| 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. | Aluminum, Stainless Steel, Steel | Custom | Gloss, semi-gloss, flat, metallic, textured | |
| 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. | All materials | n/a | Smooth, glossy finish |
