Supports bigger fasteners and accessories, providing improved rigidity and structural stability.
Versatile and widely compatible
Fully compatible with most 15 series connectors, joining plates, brackets, and panel mounts in both imperial and metric systems.
Modular and easy to assemble
No welding needed—parts can be cut, joined, and adjusted on-site with basic tools, saving time and labor.
Ideal for large-scale structures
Perfect for workstations, machine frames, safety enclosures, and custom automation setups requiring both strength and precision.
Durable surface finish
Typically anodized for corrosion resistance and a clean, professional look—suitable for industrial and commercial use.

Anodizing
Parts are machined, vibratory polished, and/or sanded as needed before entering the anodizing process.
Each step includes a visual inspection to ensure high quality and consistent surface finish.
You're not limited to natural or clear anodizing—we offer a full range of custom anodized colors to match your specific application needs.
Special coating services
Painting and powder coating are excellent alternatives to anodizing.
Chalco's special coating services allow you to integrate a variety of surface finishes into your project. Since different designs require different functions, we offer a full range of options to meet your needs:
- Powder coating
- Paint coating
- Sandblasting
- Chromate treatment
- Anodizing
- Oxidation
- Electroplating
- Galvanizing
Notes
In addition to anodized profiles, we also provide anodized connector strips, corner gussets, brackets, plates, and T-slot nuts.
Please note that if machining or cutting is required, some areas of the anodized profile may be exposed.
We're happy to assist you with any projects involving black anodized T-slot extrusions. If you can’t find what you’re looking for, feel free to contact us directly. Quick Quote

What's the difference between 10 series and 15 series?
10 series extrusions are based on 1/2-inch and 1-inch dimensions.
The centerline is 1/2 inch from the edge, and the center-to-center spacing is 1 inch.
15 series extrusions are based on 3/4-inch and 1.5-inch dimensions.
The centerline is 3/4 inch from the edge, with a center-to-center spacing of 1.5 inches.
