Sheet Metal Finishing Services for OEM Fabrication Programs

PEKO provides sheet metal finishing as a value-added capability that supports broader fabrication programs for OEM parts, enclosures, panels, welded structures, and assemblies. Rather than sending parts to an outside coater after fabrication, PEKO keeps wet painting, powder coating, and silk screening close to the manufacturing process to reduce handoffs, protect quality, and help keep schedules on track.

For OEM teams building complex products, that matters. Finish requirements often affect more than appearance. They can influence durability, corrosion resistance, labeling, downstream assembly, serviceability, and overall readiness for shipment or final integration. Because PEKO supports fabrication, welding, and assembly under one roof, finishing can be coordinated with the rest of the build instead of treated like a disconnected final step.

In-House Sheet Metal Finishing That Supports Real Manufacturing Needs

OEMs rarely need sheet metal finishing by itself. They need fabricated parts and assemblies that arrive protected, properly marked, and ready for the next stage of production, integration, or use. PEKO’s in-house finishing capabilities help reduce the risk of transit damage between vendors, improve control over quality and delivery, and simplify sourcing for programs that need more complete fabrication support.

This is especially valuable when a product includes multiple process steps. A part may move from fabrication to welding, then into a sheet metal coating process, then into silk screening, hardware insertion, or final assembly. Keeping those handoffs internal creates a more controlled path from raw material to finished product and helps OEM teams manage fewer external suppliers.

Sheet Metal Finishes PEKO Supports

Wet Painting for Large, Heat-Sensitive, or Spec-Driven Parts

Wet painting is often the right sheet metal finishing option when a fabricated part could be affected by the heat of powder coating, when the application requires a thinner finish, or when the part size makes powder coating less practical. PEKO’s in-house wet painting capability supports standard and custom colors, two-part paint systems, and specialized specifications such as CARC.

This process is well suited for large fabricated structures, appearance-sensitive parts, and applications where coating requirements, masking needs, or end-use conditions call for a wet paint process rather than a baked powder finish. It also allows painted fabricated parts to stay within the same broader PEKO workflow instead of being transferred to a separate vendor.

Powder Coating Sheet Metal for Durable, Production-Ready Protection

When durability, appearance consistency, and production efficiency are priorities, powder coating is often the better fit. Powder coating sheet metal provides a tough, protective finish that can improve resistance to wear and corrosion while supporting a cleaner, more complete finished appearance.

For many OEM programs, sheet metal powder coating is a practical choice for fabricated panels, brackets, cabinets, housings, and other components that need a durable finish and repeatable presentation. It is especially useful when finished parts must move quickly into packaging, kitting, or downstream assembly.

Sheet Metal Silk Screening for Labels, Legends, and Product Identification

Sheet metal silk screening adds functional and cosmetic information directly to fabricated products. PEKO uses this capability to apply customer-specified logos, legends, labels, and graphics to sheet metal components such as control panels, operator-facing surfaces, covers, and enclosures.

This process is useful when a part needs more than a protective finish. OEM products often require identification, branding, warnings, interface markings, or permanent visual references that hold up better than temporary labels. In those cases, silk screening helps turn a fabricated part into a more complete production-ready component.

Why OEMs Keep Sheet Metal Finishing In-House with PEKO

PEKO’s advantage is not just that these processes are available. It is that they sit within a broader manufacturing environment built to support complex OEM programs. That helps customers who need more than isolated processing. It supports programs where finish quality must align with tight tolerances, welded assemblies, branded panels, and downstream integration requirements.

It also fits the needs of OEM teams that want a supplier capable of moving from custom sheet metal parts into higher-level fabricated assemblies and equipment builds without adding unnecessary vendor complexity.

What Types of Fabricated Products Can PEKO Finish?

PEKO’s sheet metal finishing capabilities are well suited for a wide range of fabricated products, including:

Because PEKO supports fabrication, welding, assembly, and broader contract manufacturing, finishing can be aligned with the actual end use of the product rather than selected in isolation. That is important for OEM equipment programs where durability, finish quality, labeling, and integration readiness all need to be considered together.

How Finishing Fits into PEKO’s Broader Workflow

For design-stage programs, PEKO can help identify finishing requirements earlier through sheet metal prototyping and fabrication engineering support. That can help teams think through coating choice, part geometry, cosmetic priorities, marking needs, and assembly implications before the design is fully released.

For active production programs, finishing can be incorporated into a broader manufacturing flow that includes fabrication, welding, hardware insertion, screening, and final assembly. This gives OEM teams a more streamlined path to receiving finished fabricated parts and assemblies that are closer to shipment-ready condition.

FAQs About Sheet Metal Finishing

  • What Is Sheet Metal Finishing? Sheet metal finishing refers to value-added surface treatment and marking processes applied to fabricated metal parts and assemblies after or alongside core fabrication steps. At PEKO, that primarily includes wet painting, powder coating, and sheet metal silk screening.
  • Does PEKO Offer Sheet Metal Finishing as a Standalone Service? PEKO provides sheet metal finishing to support broader fabrication and manufacturing work. The value is in delivering more complete fabricated parts and assemblies through a more integrated workflow, not in operating as a general standalone finishing shop.
  • When Should I Choose Powder Coating Instead of Wet Paint? Powder coating is often the better choice when you need a durable, production-ready finish with strong wear and corrosion resistance. Wet painting is often the better fit when the part is too large for powder coating constraints, when curing heat could be a problem, or when the specification calls for a wet paint system such as CARC.
  • Can PEKO Apply Sheet Metal Silk Screening Over Painted or Powder Coated Parts? Sheet metal silk screening can be used to add logos, legends, labels, and other permanent markings to finished parts, including painted or coated surfaces, depending on the application requirements.
  • What Types of Products Commonly Need Sheet Metal Finishing? Common examples include enclosures, cabinets, chassis, panels, covers, brackets, welded structures, and operator-facing fabricated components that require protection, appearance control, or permanent identification.
