Custom Sheet Metal Fabrication

At Thieman, our professional sheet metal fabrication services use proven techniques to provide flawless execution to custom-fabricated metal parts. Known for their durability, sheet metal parts provide a viable option for many metal components, prototypes, and end-use applications.

Sheet metal fabrication are an efficient solution to form low or high-volume parts out of various forms of metal. With just a 3D CAD file, we can control a laser or plasma cutting machine that yields exact precision with each cut of metal. Sheet metal is a common raw metal that is often between 0.006 inch – 1/4 inch thick.

Sheet Metal Parts & Components

Plasma cutting creates a cost-effective way to cut thicker metals, and develop them into final components for usable parts and structures.

The chassis we fabricate are typically used to house electromechanical controls, from small handheld devices to large industrial testing equipment. All chassis are built to critical dimensions to ensure hole pattern alignment between different parts.

TMT builds custom brackets and miscellaneous laser cutting components. Our capabilities allow for fasteners and additional conveniences to be built-in to almost any manufactured part. 

Our Custom Metal Fabrication Process

Metal fabrication is a mix of custom processes that are designed to achieve a usable end-product. The sheet metal fabrication process includes various machining processes that are designed to assemble, cut, or form the metal into the desired product. Once the product or part has been fabricated, it product often needs to undergo finishing processes before it’s suitable for commercial use.

Step 1: The process begins when the desired shape is formed out of the requested sheet metal. It is then cut using one of our custom metal cutting services depending on the parts ordered.

Step 2: The shape is then manipulated and constructed into a 3D shape to bring the desired part to life

Step 3: Finally, the product is assembled and completed with the correct finish of your choice as it gets ready for further production.

Sheet Metal Fabrication Services

The ideal solution to burn, melt, cut, or vaporize small-medium sized metals to leave precise edges and high-quality surface finishes.

Proven to be one of the most cost-efficient methods for cutting large sheet metal, plasma cutting brings both speed and precision to give the exact cut for the part or application.

These extensive metal sawing capabilities can cut through dense, heavy metals, and provide matching to any fine detail. To guarantee precision results, each metal is matched with the most effective sawing technique.

State of the art technology gives all our CNC machining equipment the benefits of increased production capacity, speed, and versatility all while providing exceptional results.


Also known as Chem Film or Chemical Conversion Coating, this metal coating provides corrosion resistance and conductive properties. This coat may also be used as a base for painted or color finishes.
