A durable baked-on finish sprayed onto your metal parts and cured hard. Tougher than wet paint, in gloss, matte, textured, or metallic, and essentially any color. Applied as a secondary op after cutting, bending, or machining. Upload a part and hear back from shops set up for coating.

Finishes our coating shops run
The same laser-cut bracket in each finish, so you can read color, gloss, and texture on one reference part. Shops stock the common colors below and can order specific RAL or custom powders. If your color is not here, ask when you request a quote.

| "Powder coat it black" | "Gloss black (RAL 9005), mask the 2x tapped M6 holes, per drawing" |
| "Make it hold up outside" | "Outdoor polyester, textured black, UV-stable, qty 40" |
| "Coat these brackets" | "6061 brackets, semi-gloss black, mask the bearing bore, chase threads after" |
Give the color (a RAL number is ideal), the gloss or texture, and any threads or bores to mask. That is what sets the price and avoids a re-do.

Designing for this process
What actually changes your quote
Not a definition of powder coating. The design choices that move your price, durability, and finish.
Mask threads and bores
Coating adds 0.002 to 0.005 in per side and buries threads. Call out tapped holes, dowel pins, and bearing bores to mask, or plan to chase and ream them after coating so parts still fit.
Leave a hanging point
Parts hang on a hook to be sprayed and baked. A spare hole about 0.06 in, or a tab in a hidden spot, gives the shop a clean hanging point that will not show on the finished face.
Prep sets adhesion
The coating is only as good as the prep under it. Blasting or a phosphate wash is what makes powder resist chips and corrosion. Bare mild steel with mill scale coats poorly, so name the substrate and its condition.
Texture hides flaws, gloss shows them
A high-gloss finish shows every scratch and fingerprint on the part beneath it; matte, textured, and wrinkle finishes hide surface imperfections and resist fingerprints. Match the finish to how clean the part surface is.
Questions
Frequently asked questions
Most clean conductive metal: mild steel, stainless, and aluminum (5052, 6061, 7075), plus chromoly. The part has to survive the cure bake, roughly 375 to 400 F, so it is not suited to most plastics or low-temp assemblies. Note your substrate when you request a quote. Hot-rolled steel with mill scale coats poorly, so mention it if that is what you have.
