Anodizing
We machine, vibratory polish, and/or sand the parts as needed before applying the anodized coating.
Each stage includes a visual inspection to ensure high quality and consistent surface appearance.
You're not limited to natural or clear anodizing—we can provide any color you need to match your profiles and components with other applications.
Special coating services
Painting and powder coating are excellent alternatives to anodizing.
Chalco's special coating services give you the flexibility to apply various surface treatments to your project. Since different designs require different functions, we offer a wide range of options to meet your needs:
- Powder coating
- Painting
- Sandblasting
- Chromate treatment
- Anodizing
- Oxidation
- Electroplating
- Galvanizing
Notes
In addition to anodized profiles, we also offer anodized connectors, gussets, brackets, plates, and T-nuts.
When ordering anodized T-slot extrusions, please note that machined or cut areas may expose unfinished surfaces.
We're happy to support any project involving black anodized T-slot profiles. If you can’t find the exact product you need, feel free to contact us anytime. Quick Quote
