Most of the commercial work at Finish Logic’s Concord shop arrives the same way it has for years: a fabricator from the industrial corridor drops off a rack of parts, says what color and when it is needed, and picks the batch up coated. No portal, no procurement funnel. This page covers what the shop runs, how the process works, and what to bring for a quote.
TL;DR
-
Finish Logic powder coats batch and one-off commercial work for fabricators and manufacturers in Concord, Martinez, Pacheco, and Pleasant Hill, roughly a 15-mile working radius around the Concord shop.
-
The shop runs an industrial powder coating booth, a sandblasting cabinet, a large parts oven, and a batch processing line, with multi-color capability across runs.
-
Every job follows the same sequence: chemical strip, media blast, coat. Blasting is generally the last stage before coating.
-
Recurring batch runs and one-off jobs share the same line. Most commercial customers walk in or call; that is how the corridor trade works.
Is There an Industrial Powder Coating Shop Near Concord That Handles Batch Work?
Finish Logic operates at 5650 Imhoff Dr, Unit L, Concord, in the middle of the industrial corridor it serves. The commercial catchment is deliberately local:
-
Concord and Pacheco
-
Martinez
-
Pleasant Hill
That is roughly a 15-mile working radius. Jobs from further out get quoted case by case rather than promised by default. Most of the commercial customer base found the shop the way industrial-park neighbours do: someone at the next unit over had their parts coated here and said so. That grapevine, plus 132 Yelp reviews, is the marketing.
What Does the Shop Actually Run?
The honest equipment list, because that is what a fabricator wants to know before loading a truck:
-
Industrial powder coating booth for commercial-scale parts
-
Sandblasting cabinet for rust, scale, and oxide removal
-
Large parts oven for oversized fabrications and long sections
-
Batch processing line for recurring production runs
-
Multi-color capability, so a mixed release does not need to wait for a single-color week
Recurring batch runs and one-off jobs share the same line. A monthly release of brackets runs alongside a single custom gate, and both get the same prep sequence. There is no separate retail counter and no separate production wing. It is one shop, and that is the point of using it.
How Does the Process Work on a Commercial Job?
Every part, batch or one-off, moves through the same three stages:
-
Chemical strip. Old coatings, grease, and failed finishes come off chemically, down to bare metal. Nothing gets coated over.
-
Media blast. Blasting removes rust, mill scale, and oxidation and cuts the anchor profile the powder grips. It is generally the last stage before coating.
-
Coat and cure. Powder is applied to clean, profiled metal and oven-cured. Bare steel headed outdoors gets a zinc-rich primer before the topcoat.
The order matters: stripping first means the blast works on metal rather than on old paint. For the full breakdown of why this sequence decides coating life, see Surface Preparation: Why It Determines Coating Durability.
How Does Commercial Powder Coating Pricing Work?
There are no published price tiers. Every job is quoted, and the quote follows the same cost drivers whether it is 5 parts or 500:
| Cost driver | Why it moves the quote |
|---|---|
| Batch size | Setup and racking are fixed per run, so per-part cost falls as the batch grows |
| Part size and geometry | Bigger and more complex parts take more rack space, powder, and oven time |
| Condition at drop-off | Parts arriving with old coatings or heavy rust need full stripping and more blast time |
| Color grouping | Batches grouped by color avoid changeover time; one-off custom colors add it |
| Masking | Threads, bores, and mating faces that must stay bare add labor per piece |
The practical version: bring the part count, the condition, and the color, and the quote comes back with a real number and a real date. Repeat runs are quicker to quote because the job has been run before.
What About Repeat Runs and Turnaround?
When the same part comes back three months later, say so. Repeat jobs run to the previous job’s spec, same powder, same color, same masking, without re-explaining the work from scratch. That is what the batch processing line is for, and it is why several corridor fabricators send recurring releases here.
Most batch jobs run about two weeks from drop-off, and the timeline is quoted with the job, since queue, part condition, and batch size all move it. If a deadline is tight, call before loading the truck and ask; the answer will be straight either way.
Frequently Asked Questions
Do we need an appointment or an account to bring in commercial work?
No. Walk-ins are how most of the corridor trade works. Bring the parts, or call 925-788-2911 first if the load is large enough to need planning. There is no account setup process; the first job establishes the spec and repeat runs refer back to it.
Is there a minimum order size for commercial powder coating?
No fixed minimum. One-off pieces and recurring batches run on the same line. Small batches carry proportionally more setup cost per part, which the quote will reflect honestly.
Can you match the color from our last run?
Yes. Repeat jobs run to the previous job’s spec, same powder and color. Name the earlier job when you book the run so it is pulled up rather than re-quoted from scratch.
How fast can you turn a commercial batch around?
Most batch jobs run about two weeks from drop-off. The timeline is quoted with the job because part condition, prep needs, and the current queue all move it. Ask about rush handling when you call; it depends on the week.
What should we bring to get a quote?
Part count, dimensions or a sample part, the substrate, the color, and the deadline. Photos work if the parts are still on site. That is enough for a real quote rather than a ballpark.
