Sheet Metal Assembly Fabrication for Complex OEM Equipment

PEKO provides sheet metal assembly services for OEMs that need more than cut and formed parts. We help turn fabricated components into subassemblies, enclosures, chassis, cabinets, brackets, and equipment structures for complex machinery and electromechanical systems. As part of our broader precision sheet metal fabrication capabilities, PEKO supports sheet metal product assembly programs that require coordination between fabrication, joining, finishing, and final integration. Whether you need a close-tolerance sheet metal assembly built from a few fabricated parts or a more involved assembly fabrication program with hardware, wiring paths, and purchased components, we provide the manufacturing depth to execute it with control.

Why OEMs Choose PEKO for Sheet Metal Assembly Services

Built for Complex, Close-Tolerance Assemblies

PEKO supports custom fabricated sheet metal assemblies for OEM equipment where structural integrity, alignment, finish quality, and repeatability matter. These assemblies often serve as the mechanical foundation for larger systems, so every detail must support downstream fit and performance.

Integrated Fabrication, Finishing, & Assembly

The parts feeding your assembly can be fabricated, welded, finished, and inspected within the same manufacturing environment. That reduces handoffs, shortens feedback loops, and gives your program tighter control over quality before components reach the assembly floor.

Program-Driven Quality & Repeatability

For each assembly program, PEKO develops a repeatable build process supported by work instructions, inspection points, standardized travelers, and application-specific tooling or fixtures. This helps ensure that pilot builds and recurring production assemblies are built with the same discipline and consistency.

Scalable Support from Prototype to Production

PEKO can support early prototype and pilot builds, production transfers, and recurring low-volume production sheet metal fabrication. Whether you are launching a new program or improving an existing one, our team helps create a more controlled, repeatable assembly process.

Electromechanical & Value-Added Integration

Some fabricated assemblies are primarily structural. Others require wiring, grounding, cable routing, installed hardware, or integration into a larger system. PEKO can bridge from sheet metal fabricated assemblies into mechanical assembly and electromechanical assembly when the build requires more than structural fabrication alone.

Engineering Collaboration & DFMA Support

PEKO works with OEM teams to improve manufacturability before assembly challenges become production problems. Through our sheet metal engineering services, we help evaluate part geometry, joining strategy, tolerance stack-up, hardware selection, and other design details that affect cost, build time, and assembly quality.

Types of Sheet Metal Assembly PEKO Builds

Our sheet metal assembly services are well suited for:

These assemblies often serve as the structural platform for larger machines and equipment, so fit, alignment, hardware integration, and build consistency are critical.

Our Sheet Metal Assembly Capabilities

PEKO supports a range of joining and assembly methods based on the application, material, geometry, service requirements, and production volume. Our capabilities can include:

  • PEM fasteners, studs, standoffs, threaded inserts, and other hardware insertion
  • blind rivets, solid rivets, and other mechanical fastening methods
  • spot welding, MIG welding, and TIG welding
  • tab-and-slot and other self-locating design features
  • adhesive bonding for select applications
  • painting, powder coating, silk screening, and other finishing support
  • part kitting, staged assembly flow, and assembly documentation
  • inspection checkpoints and quality verification
  • integration of machined, purchased, and electromechanical components

Our Sheet Metal Assembly Process

  1. Component Fabrication: Sheet metal parts are produced through the required cutting, forming, welding, and hardware-prep operations.
  2. Inspection, Kitting, Staging: Parts are verified, organized by subassembly or traveler, and prepared for efficient assembly flow.
  3. Mechanical Assembly: Technicians build the assembly using the appropriate fastening, insertion, or joining method.
  4. Integration of Value-Added Content: When required, the build can include installed hardware, purchased components, wiring accommodation, or higher-level system elements.
  5. Quality Checks & Verification: Assemblies are inspected for dimensional alignment, fastening integrity, finish quality, and readiness for the next manufacturing step.
  6. Packaging & Delivery: Completed assemblies are packaged to protect the build and support the next stage of integration or final shipment.

Industries We Support

PEKO supports sheet metal fabricated assemblies for OEMs in high-reliability industries such as:

Because many of these products involve complex machinery, electronics, or regulated performance requirements, OEMs often need an assembly partner that can support more than part fabrication alone. PEKO’s combination of fabrication, assembly, engineering support, and quality control helps customers launch, transfer, refine, and scale complex assembly programs with greater control and less risk.

Typical end uses include equipment platforms, controls-ready enclosures, structural supports, and integrated assemblies used within larger OEM systems.

Fabricated Assembly FAQ

  • What Is Sheet Metal Assembly? Sheet metal assembly is the process of joining fabricated sheet metal parts into a finished subassembly or larger product structure. Depending on the application, that may include hardware insertion, riveting, welding, fastening, finishing coordination, and integration with machined or purchased components.
  • Does PEKO Only Assemble Customer-Supplied Parts? PEKO can fabricate many required parts in-house and assemble them under the same program structure, helping improve quality control, reduce coordination issues, and streamline lead times.
  • Can PEKO Help Improve an Existing Assembly Design? PEKO can provide design-for-manufacturing and assembly support to help improve fit, function, cost, part count, joining strategy, and overall manufacturability.
  • What Should OEMs Look for in a Sheet Metal Assembly Supplier? OEMs should look for a supplier that can control fabrication quality, support the right joining methods, manage finishing and hardware requirements, document the build process, and deliver repeatable assemblies at the required lifecycle stage.
