All Cartesian Tube Profiling kits in aircraft-grade 4130 steel tubing are pre-engineered in 3D using computer aided design.
Every tube is profiled in one setup to ensure accurate profiles and clock orientation at both ends, and controlled length
Joints for welding fit within tolerances of less than .005 inches
Joint angles can be as acute as 20°, or even less
Complex tube clusters are pre-cut to fit, for intersections of up to 8 tubes, in any combination of tube diameters
Tubes range in diameter from 1/4" to 2"
Complicated clusters weld more simply, cleanly and quickly
Every tube is cataloged, labeled and ready to weld

This unprecedented precision at the welding stage will help you maintain accuracy further along your project’s assembly.

And every tube part we produce is cataloged and stored in our CAD system’s computer. If something happens to a part and you need it replaced, we can cut a new one and ship it to you right away.

You’ve simply never seen tubes and joints that fit so precisely and weld so easily

We work from 3D CAD drawings

...to create a set of pre-cut tubes

...with every piece cataloged and labeled

...and it all arrives in a shipping crate.
