Custom Aluminum Extrusion, Laser Cutting & CNC Bending

By combining custom extrusion profiles (6061/6063-T5/T6) with precision CNC stretch-bending, laser cutting, and secondary 5-axis milling, we eliminate costly weldments and reduce part weight.

  • Extrusion Alloys: EN AW-6063 / AA 6063 (T5/T6), EN AW-6061 / AA 6061 (T6), 7075-T6
  • Cross-Section Capacity: 10 mm to 500 mm (0.4″ to 19.7″) profile width
  • Sheet Metal & Bending: Fiber Laser Cutting, CNC Press Brake Bending, TIG/MIG/Laser Welding
  • In-House Finishes: Clear/Black Anodizing, Cathodic E-Coating, Powder Coating, Bead Blasting
