Rapid and Affordable Sheet Metal Fabrication Services

Sheet metal fabrication is the process of converting sheet metal made of aluminum, steel, stainless steel, zinc, copper, and brass into parts and assemblies. During sheet metal fabrication, different techniques are often combined to create the desired part. The required processes include cutting, bending, punching, stamping, welding and finishing. These technologies complement each other and play a vital role in the successful completion of the project. Sheet metal fabrication services are widely used in industrial and consumer parts as well as specialized industries such as automotive, aerospace, energy and robotics.

Laser Cutting

Laser Cutting

Laser sheet metal fabrication or laser sheet cutting has been successfully used in various industries and refers to the process of cutting metal material into desired shapes using a high power density laser beam.

Waterjet Cutting

Waterjet Cutting

Waterjet cutting is a sheet metal manufacturing method that uses high-pressure water jets (mixed with abrasives) to cut metal, especially for cutting low-melting sheet metal.

Plasma Cutting

Plasma Cutting

Plasma cutters create an electrical pathway of ionized gas that creates a jet of hot plasma that can easily penetrate thick-gauge sheet metal. Its cost is relatively lower.

Sheet Metal Bending

Sheet Metal Bending

The sheet metal bending process involves passing a sheet of metal through a wedge-shaped tool (cutter) to apply pressure, push it into a V-shaped opening and bend the sheet to the desired angle.


Sheet Metal Stamping

Sheet metal stamping (also known as sheet metal pressing and forming) is the process of pressing flat metal in coil form through dies to form parts of the desired shape.

Sheet Metal Welding

Sheet Metal Welding

Sheet metal welding refers to the process of joining heated and melted sheet metal parts together to increase their strength or create a single integrated product.

Surface Treatment of Sheet Metal Manufacturing Parts

Surface preparation is an important aspect of custom sheet metal fabrication. It imparts functional and aesthetic advantages to manufactured parts. Here are some surface treatment options for sheet metal fabricated parts:



Anodizing can improve the corrosion resistance, wear resistance and hardness of aluminum parts and protect the surface.


Bead Blasting

Bead blasting results in parts with a smooth surface with a matte texture.

sheet plating


Plating can be functional, decorative or related to corrosion protection, with chrome and nickel plating of steel auto parts being common.


Powder Coating

Powder coating is a free-flowing dry powder that is electrostatically coated on the surface of a part and then cured by heat or ultraviolet light.



Polishing is the process of creating a smooth, shiny surface through physical friction or chemical interference.

sheet metal 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.


Laser engraving

Laser engraving is the process of hitting a localized area of a part with a large amount of energy, vaporizing the material into smoke to engrave a permanent mark.

sheet metal Screen printing

Screen printing

Screen printing is a printing technique where a mesh is used to transfer ink (or dye) onto a substrate, except in areas made impermeable to the ink by a blocking stencil.

Design Considerations for Sheet Metal Fabrication

After years of experience in sheet metal manufacturing, AN-Prototype has concluded that the following are some important design features to consider when modeling sheet metal parts:

Wall Thickness

Achieving uniform thickness is critical to producing high-quality parts. Manufacturing sheet metal geometries with multiple wall thicknesses can cause alignment and orientation issues, resulting in inaccurate parts and extended production times. Therefore, careful consideration must be given to geometry and material thickness to ensure that the final product meets the required specifications and standards.

Bend Radius

It is very important to maintain the internal bend radius of the sheet metal at least equal to its thickness. This will help avoid warping and shattering in the final part. Keeping the bend radius consistent across the part ensures cost-effectiveness and good orientation.

Bend Allowance and Deduction

Bend Allowance is the material that needs to be added to the actual length of the part to help create a flat pattern. Bend deduction refers to the material that needs to be removed from the length of the flange to help achieve a flat pattern.


The K-Factor is a key parameter that determines the ratio of the neutral axis to the thickness of the material. This value is not constant and can vary depending on the physical properties and thickness of the material used in the manufacturing process. Knowing the K-Factor is critical to achieving accurate sheet metal bends.

Orientation of holes and slots: The diameter of the holes and slots should be at least as large as the thickness of the sheet metal. In addition, the spacing of the holes should be reasonable. They should never be too close to the edge of the material.Other additional features to consider include flanges, notches, tabs, rolled edges, fillets, countersinks.
