CURRENT, INC. Laminated Tubing is made of thermosetting resins (Phenolic, Epoxy, or Melamine) combined with various base materials such as cellulose paper, woven cotton cloth or glass cloth. Convolutedly wound under high pressure and heat, the resulting product is a dense homogeneous material that can be machined, polished, painted and printed on. Laminated Tubing is easy to saw, drill, tap, thread, and punch with ordinary tools. The material has excellent electrical insulating qualities. It’s lighter, more durable and more economical than metal in many instances.

In the past decades, hundreds of applications for our tubing have been employed. The potential of new space age applications is even more exciting.

CURRENT, INC. Laminated Tubing is available in lengths from 36” to 48” depending on grade, diameters from 0.187” ID to 4.000” ID; OD from 0.200″ to 5.000″. Larger sizes quoted on request. Finishes include ground, polished, based on requirements. Tolerances are to NEMA standards. For special tolerances, please contact our sales office.

Whatever you manufacture or assemble, there is an excellent chance that there is a Current Inc. product that will improve your product. We’ll quote at no charge, just send us your specs and/or blue prints.

High Strength Laminated Tubing for Electrical, Mechanical, and Structural Applications

Current Inc. manufactures laminated tubing engineered for durability, stability, and consistent machining performance. Each tube is produced using thermosetting resin systems, phenolic, epoxy, or melamine, combined with carbon fiber, cellulose paper, woven cotton cloth, or glass cloth reinforcements. These materials are convolutely wound under controlled heat and pressure to create a dense, uniform structure that performs reliably in demanding environments.

Material Construction and Performance

Laminated tubing offers excellent electrical insulation, strong mechanical properties, and predictable machining behavior. The material can be drilled, tapped, threaded, punched, or cut using standard tools, making it suitable for both high volume manufacturing and custom fabrication. Tubes can be polished, painted, or printed on, and their lightweight construction provides an advantage over metal components in many applications.
