What Is Metal Fabrication?

Metal fabrication is the process of turning raw metal materials into custom parts, components, and assemblies through a combination of manufacturing techniques.

Typical metal fabrication processes include:

Cutting

Removing material to create the required shape and size.

Forming

Bending or shaping metal into specific designs.

Welding

Joining multiple metal components into a complete structure.

Machining

Creating precise features and tight tolerances through CNC processes.

Finishing

Improving surface quality, appearance, and durability.

Assembly

Metal Fabrication Processes

Different metal fabrication projects require different manufacturing approaches depending on part design, material selection, production volume, and performance requirements.

Our fabrication capabilities cover a range of processes, from initial material preparation to precision machining and final surface treatment.

Cutting

Cutting is the first step in many fabrication projects, creating the basic shape and dimensions of metal parts before further processing. Common methods include laser cutting, plasma cutting, waterjet cutting, and precision sawing.

Forming

Forming processes reshape metal materials into specific profiles and structures while maintaining material strength. These processes are commonly used for brackets, enclosures, frames, and custom sheet metal components.

Welding

Welding provides strong and reliable joints between metal components, making it essential for structural parts, frames, and assemblies that require durability and stability.

Finishing

Finishing processes enhance the appearance, protection, and performance of fabricated metal parts. Options may include anodizing, powder coating, polishing, plating, and other surface treatments.

CNC Machining

CNC machining delivers the precision required for complex features, tight tolerances, and functional surfaces. It is often used after fabrication processes to achieve final dimensions and critical specifications.

CNC Machining in Metal Fabrication

While metal fabrication creates the overall structure and form of a component, CNC machining provides the precision required for critical features and functional performance.

Many fabricated parts require additional CNC machining after cutting, forming, or welding to achieve the accuracy and specifications needed for final applications.

CNC machining is commonly used for:

Tight Tolerances

Maintaining precise dimensional accuracy and consistency for critical components that require reliable performance and repeatable manufacturing results.

Precision Holes

Creating accurate hole locations and diameters for assembly, fastening, and component integration.

Threaded Features

Machining internal and external threads for secure connections and mechanical fastening.

Mounting Surfaces

Producing flat, accurate surfaces for proper installation and alignment with other components.

Alignment Surfaces

Achieving tight tolerances to ensure precise positioning and reliable operation.

Complex geometries

Manufacturing detailed contours, pockets, slots, and custom features that cannot be achieved through traditional fabrication methods.
