Copper Bar Products

Three D Metals stocks copper rectangular bar in an extensive range of sizes to meet the demands of electrical or industrial applications:

  • Length: 12′ standard
  • Alloys: CDA 102, 107, 110, and 116 (ASTM B-152/B-187)
  • Edge options: Square edge, rounded edge, radius edge, and full rounded edge
  • Finishes: Bare, silver-plated, and tin-plated
  • Additional capabilities: Custom fabricated busbar, machined-to-print, trapezoids, special shapes and custom extrusions, and metric sizes available

Copper Bar for Switchgear Applications

Busway, also known as bus duct, is a prefabricated power distribution system that uses solid copper conductor bar in place of traditional cable and conduit. It’s commonly used in data centers, industrial facilities, and construction applications where high-amperage, reconfigurable power distribution is critical.

Three D Metals supplies CDA 102 copper bar in the sizes, edge profiles, and finishes busway fabricators require, with custom cutting available.
