Steel Pipe

Dominion leads in steel pipe supply

Dominion has been supplying steel pipe since the origin of our company. In fact, steel pipe became the product we are known for within the industry.As the construction industry evolves, we work hard to keep up with the changing needs of our customers. Over the last few years, we have added several more support system products to our product line to increase choices for our customers in both project planning and price, while remaining leaders in steel pipe supply.Steel pipe is commonly used when the soil near the ground surface is not strong and therefore the weight of the building must be carried by deeper soil layers. Dominion offers all grades of steel pipe from 1/2" to 96" diameter.


We also offer new, overstock and surplus materials in the following grades:

  • ASTM A252
  • A53 B
  • API
  • A139
  • AWWA C200
  • CSA


Steel pipe is commonly used in:

  • Water transmission, penstock, water drilling and treatment facilities
  • Structural support below the surface
  • Fire protection
  • Agricultural, industrial and energy applications
