How it works
Our Powder Coating Process
Professional Preparation. Consistent Results.
From large fabricated assemblies and production runs to architectural components and specialty parts, every project follows a proven process for preparation, coating, curing and final inspection.
From Bare Metal to a Finish That Lasts
Powder coating is only as good as the prep underneath it. That's why every job, from a single fabricated assembly to a full production run, goes through the same eight steps.

Project Review & Quote
Every project starts with a review. Send us your drawings, photos, dimensions and quantities, or bring the parts in, and we look at exactly what the job needs before we price it.

02
Sandblasting
Powder only bonds well to clean, bare metal, so almost every part goes through our 20' × 10' × 10' in-house blast booth first. Abrasive media strips rust, old paint, powder and scale down to the substrate and leaves a uniform surface profile.
That profile is what gives the new coating something to grip. Skipping this step is the number one reason coatings from other shops peel.
· 20' × 10' × 10' in-house blast booth
· Long and oversized parts blasted in one piece
· Removes rust, paint and old powder
· Uniform anchor profile for adhesion
· Sandblast-only service also available
03
Surface Preparation
After blasting, parts are hand-sanded and detailed. We knock down high spots, clean out corners and pockets the blast media can't reach, and chase any surface imperfections that would show through a smooth gloss finish.
Parts are then degreased and cleaned so no oil, dust or fingerprints end up sealed under the coating.
· Hand sanding and edge work
· Degreasing and pre-treatment
· Filler on deep pits where needed
· Final wipe-down before masking


04
Masking & Plugging
Anything that shouldn't get coated gets protected. High-temperature tape and silicone plugs go over threads, bearing seats, ground contacts, bolt holes and mating surfaces so hardware still fits and tolerances hold after coating.
On commercial and industrial parts we work from your drawings or mark-ups, and flag anything unclear before the part is coated.
· High-temp masking tape and plugs
· Threads and bearing seats protected
· Two-tone and custom masking available
· Follows customer drawings
05
Primer / Coating System
Not every part needs the same coating system. Before powder goes on, we match the primer and topcoat to the substrate, the environment the part will live in and your project requirements.
Exterior and coastal work, castings and galvanized parts prone to outgassing, and jobs with a written specification can each call for a different system.
· Epoxy primers
· Zinc-rich primers
· Anti-gassing primers
· Super durable polyester
· Exterior and coastal systems
· Specialty finishes


06
Powder Application
In the spray booth, dry powder is given an electrostatic charge and sprayed onto the grounded part. The charge pulls powder evenly into edges, corners and recesses that liquid paint would miss or run on, and it wraps around the back of tubing and mesh.
There are no solvents and no VOCs, and any overspray is collected and recycled rather than released.
· Electrostatic, even coverage
· Thousands of colors, glosses and textures
· No solvents or VOCs
· Overspray captured and reused

07 · Oven Curing
20' × 10' × 10' Industrial Curing Oven
Coated parts go straight into our 20' × 10' × 10' industrial curing oven, where the powder melts, flows and cross-links into a single continuous layer. Long beams, frames and full production racks cure in one piece, in one cycle.
Once cured, the finish is far harder and more chip-, scratch- and corrosion-resistant than liquid paint.

Final Inspection & Delivery
After cooling, masking comes off and every part goes through final inspection and quality control before it is released. Anything that doesn't meet the standard is corrected before it leaves our shop.
Approved parts are packaged to protect the finish, then staged for pickup or loaded on our truck for delivery.

Pickup & Delivery for Commercial & Production Work
Our truck collects parts from your shop or job site and brings them back finished. For large fabrications, repeat production orders and anything too heavy or awkward to move yourself, we schedule pickup and delivery around your project.
Built to Last
Powder coating forms a thicker, harder film than liquid paint, so it stands up to chips, scratches, UV and corrosion for years.
Cleaner Process
No solvents and no VOCs. Overspray is captured and recycled instead of going into the air or the drain.
Any Part, Any Size
From structural beams, gates and stadium signage to production racks of small parts, our San Diego facility handles it in-house.
