What is the difference between TSLOTS and the "other" guys?

We are part of Bonnell Aluminum, the 3rd largest soft alloy aluminum manufacturer of custom aluminum extrusions in the U.S. — and the fastest-growing structural aluminum profile supplier in the United States. Bonnell Aluminum has been helping customers optimize aluminum extrusion designs and minimize. Today, Bonnell creates a variety of products that include TSLOTS, the only T-slotted aluminum extrusions manufactured and distributed by an aluminum extruder.

Do TSLOTS come in different colors?

We’re the extruder, so we can create TSLOTS in a variety of colors and lengths of up to 8 feet.

When should I use components vs. machining to assemble my design with TSLOTS?

Machined extrusions have a clean look and are structurally stronger than components. However, component assembly works well if you plan on adding to your design. When it comes to cost, machining will often save you the most money.

Do TSLOTS come in metric or fractional sizes?

As the extruder, we’re in the rare position to make TSLOTS in both metric and fractional sizes — right here in the U.S.A.

Are all T-slotted extrusions the same?

No. Many manufacturers have unique T-slotted designs so their components don’t fit with others. In addition, the aluminum alloys used in different manufacturers’ extrusions can vary, creating different strength and finish characteristics.

How are TSLOTS shipped?

Kit-packed TSLOTS less than 8 feet long can be shipped by UPS. These tend to be the most cost-effective. You can also order TSLOTS in stock lengths of 20 feet or have your design assembled and delivered ready to use. Read more about how TSLOTS are shipped.

What do I need to cut this material on site?

We recommend a miter or chop saw equipped with a carbide aluminum cutting blade. (12″ diameter blade should be 100 tooth). Make sure to use a cutting lubricant to extend your blade life and maintain the quality of the cut. Most importantly be SAFE! Ensure your area is safe and your work is secured properly when cutting. We also offer in-house cut-to-length service for your project needs.
