Electrical Resistance
Welded Tubing (ERW)

PTC manufactures premium ERW tubing in a wide array of sizes and grades for agriculture, automotive, appliance, construction, recreation, and heavy truck manufacturing.


Versatile and Cost-Effective ERW Products for Diverse Fabrication Needs

Electrical Resistance Welded (ERW) products can be an ideal choice when strength-to-weight ratio is critical, or when bending, flattening, flaring or other types of fabrication will be required. 

For many applications including prop and drive-shaft tubing, steering column components, recreational equipment, and valve casings, ERW products offer significant cost savings throughout the fabrication process. Because of its excellent workability, scrap loss is minimal. Due to its uniformity and concentricity, lighter walls can be specified, reducing the allowance for stock removal. 

PTC offers an unparalleled range of sizes from fourteen weld mills in six locations including both high and low-frequency. 

Inside flash may be rolled, removed by scarfing, or may remain. The weld is carefully examined by destructive and non-destructive means.

Common Application: 

  • Axle housings
  • Boiler tubing
  • Conveyors
  • Vehicle frames
