Finishing Options For Sheet Metal Part

We provide various surface finish options for your sheet metal project. If your required surface treatment is not listed below, feel free to contact us for more options.

As the machined or deburring

The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).

Bead Blasted

Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.


Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.

Powder coating

Powder coating is the electrostatically applying of dry powder to the surface. It produces a thin layer providing excellent resistance to wear, corrosion, and abrasion.


Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.


Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.

Smooth machining

Smooth machining is done by controlling the machining process, such as feed rate & cutting speed. It minimizes the tool marks and risk of corrosion.


Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.


Fine machining

The higher-precision machines produce delicate machining surfaces by utilizing sharper tools and regulating feed rate and cutting speed. Surface roughness up to Ra 0.8 μm can be maintained with smooth machining.


Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

What is Sheet Metal Fabrication?

Sheet metal fabrication is converting the metal sheet into the desired shape. The process involves more than one step while manipulating the sheet metal to form the body, such as cutting, bending, welding, surface treatment, and many more, depending upon the complexity of the required shape.

The fabrication of sheet metal begins with drawings (2D& 3D). However, before starting the actual fabrication, manufacturers develop a 3D such as a CAD file. The 3D of desire shape provides guidance on what actions should be made, which strategy is the most appropriate and practical, which manufacturing steps are needed, and many other things.


• Sheet metal fabrication is the low-cost and effective approach for prototype development and large-scale production.
• The finished part or product made of sheet metal has a high strength-to-weight ratio.
• Sheet metal fabrication offers a wide range of material options to create the desired shape.

Fabrication Steps

The steps of sheet metal fabrication begin with preparing a complete blueprint of required parts. For example, it might be the paper drawing or CAD-3D containing all dimensions. Then, it requires identifying the manufacturing steps such as cutting, bending, welding, assembly, & surface treatment.

Cutting the sheet metal is the step where the actual fabrication starts. Cutting the sheet metal into pieces as the dimension in the drawing can be achieved with various approaches such as CNC cutting, Laser cutting, and Water-jet cutting. After the Cutting operations, the cutting pieces need to be joined to form the shape with Riveting & welding. Other processes, such as bending and turning, are involved if angular or complex shapes are required. If holes are present in the shape, punching or drilling operations are used to create them.

Assembly of components is done to produce the desired shape according to the design of parts or products. Last but not least, surface finishing procedures, including plating, deburring, powder coating, or painting, must be carried out.


Several industries use sheet metal fabrication processes to create parts and the final product.

  • Automotive
  • Aerospace
  • Defense
  • Agriculture
  • Medical
  • Home appliances
  • Construction
  • Electrical & electronics
