Industry-Leading Steel Extrusions

Plymouth®’s specialized approach achieves geometries and performance standards beyond the scope of traditional methods, delivering a level of structural complexity in stainless and carbon steel that is rarely matched by alternative materials. These advantages—specifically superior surface integrity and unmatched straightness—are application-critical for long-length structural or architectural environments where precision is a requirement, not an option.

By co-designing custom extruded shapes for specific applications, Plymouth® provides more than just a component; we provide a strategic manufacturing advantage. This collaborative engineering affords manufacturers several key benefits:

  • Minimal Tooling: Our steel extrusions are designed and fabricated for a precise fit, reducing the amount of tooling required before being used for manufacturing.
  • Reduced Material Usage: By using specifically engineered shapes, manufacturers use less material in cutting or forming individual component parts.
  • Lower Parts Count: Well-designed extruded shapes can eliminate the need for multiple smaller component parts, lowering a project’s overall parts count.
  • Less Downstream Machining: The customized designs of our extrusions delivers components requiring minimal removal of excess material.
  • Reduced Finishing: The surface quality of our steel extrusions saves time by reducing the need for polishing, straightening, deburring, and other finishing processes.
