Anodizing
Chromic Type I, sulfuric Type II, and hardcoat Type III anodize options for aluminum components requiring corrosion resistance and surface durability.
What We Process
One finishing center, three critical surface treatments.
Our finishing department is designed to support demanding components that cannot afford dimensional drift, cosmetic inconsistency, or outsourced scheduling delays. By keeping chemical processing close to machining, Norris shortens the path from raw material to ready-to-install hardware.
The result is a cleaner handoff, tighter quality oversight, and a production rhythm better suited to aerospace, defense, and medical programs.
Anodize
Chromic Type I, sulfuric Type II, and hardcoat Type III anodize, including enhanced chromic and controlled-thickness sulfuric processes.
Chem-Film
Chemical conversion coating for conductivity, adhesion, and lightweight protection.
Passivation
Stainless surface treatment that restores corrosion resistance on critical hardware.
New finishing expansion
Facility growth focused on better flow, better control, and reduced lead time.
Core Processes
Built for parts that need protection without compromise.
Chemical Film
Conversion coatings that preserve conductivity while preparing parts for downstream assembly or paint systems.
Passivation
Controlled treatment for stainless components where corrosion resistance and process repeatability matter.

Facility Showcase
Inside the new Norris Metal Finishing Facility
Clearwater, Florida
Facility growth built around cleaner flow from machining to finishing.
The expanded footprint gives Norris more room to route work efficiently, protect parts during handling, and reduce lead time without giving up process control.
Why It Matters
Finishing stays integrated with production from machining through final inspection.
Controlled Quality
Surface treatment remains tied to the same quality culture governing machining and final inspection.
Shorter Lead Times
In-house finishing removes outsourced queue time and simplifies the route from production to shipment.
Better Part Protection
Process ownership helps preserve fit, finish, and dimensional intent on complex hardware.
