What we source
Metal finishing
Amerigo sources metal finishing from American finishing shops: powder coating and wet paint, zinc and nickel plating, anodizing, passivation and blasting. Send the drawing or a parts list with the finish spec and we route it to a few shops that run that finish. Each shop that quotes sends back its own name, price and ready date, and you pay one price through Amerigo.
Send a drawingAbout metal finishing
Finishing is protection and appearance: powder coat and wet paint for steel and aluminum in a specified color and texture, zinc or zinc-nickel plating for corrosion protection on steel hardware and brackets, anodize (Type II or hardcoat Type III) for aluminum, passivation and electropolish for stainless, and blasting or tumbling for a uniform surface before any of them.
Most finishing rides on the fabrication or machining order: the fabricating shop finishes in house or sends it to a partner. Finish-only work is for parts you already have, or a finish your fabricator does not run. Masking, racking and plugging threaded holes are the details that change price, so call them out on the drawing.
Questions buyers ask
- Can I send my own parts for finishing?
- Yes. Send the drawing or a parts list with quantity, material, the finish spec and color, and where the parts are now.
- What finish spec do I put on the drawing?
- The one your application needs: a color code and gloss for powder coat, a plating spec and thickness for zinc or nickel, MIL-A-8625 type and class for anodize, ASTM A967 for passivation. If you do not have a spec, describe the environment and the shop can propose one.
- Do finishing shops mask threads and faces?
- When the drawing says so. Unmarked threaded holes get coated, so call out every surface that must stay bare.
- Can the finish be on the same order as the fabricated parts?
- Yes. Put the finish on the drawing and the fabricating shop quotes it with the parts, finished in house or through its finishing partner. The quote states what it includes.
