Steel tubing for the way the West builds

Four core product lines, manufactured in Arizona from prime high-quality domestic raw materials that conform to stringent ASTM steel specifications. ISO 9001 certified and Buy American Act qualified, with tube melted and poured in the USA. Every line below is built to spec and ready to quote.

Galvanized Tubing

LP Tube manufactures Galvanized steel tubing and pipe primarily for the fence and mechanical distribution market segments. All Galvanized product strictly conforms to ASTM A-787, with coating to ASTM A-653 and ASTM F-1043. The outside-diameter weld seam of each tube is re-metalized after forming and high-frequency welding, then coated with a chem-treat conversion coating and sealed with a clear acrylic finish. The finished tube is cut to length in-line as a clean, dry product.

Ornamental Tubing

LP Tube manufactures ornamental P&O steel tubing for the steel service-center and distribution sectors. All ornamental product strictly conforms to ASTM A-513 and is made from prime high-quality raw materials. The line meets or exceeds allowable tolerances for size, tight corner radii, straightness, wall thickness, and precise length, with a superior surface finish and a light film of water-soluble rust preventative on every piece.

HSS A500 Tubing

LP Tube manufactures hollow structural sections (HSS) for the steel service-center and distribution sectors. All HSS product conforms to ASTM A-500 Grade B/C and is made from prime high-quality domestic raw materials, meeting or exceeding allowable tolerances for size, straightness, wall thickness, and precise length. Square and rectangular sections are available in heavier gauges for load-bearing and structural applications.

Galvanized Coating Processes

All Galvanized product is produced from prime high-quality domestic raw materials. The outside-diameter weld seam of each tube is re-metalized after forming and high-frequency welding. The product is then coated with a chem-treat conversion coating and sealed with a clear acrylic finish, cut to length in-line as a clean, dry product suitable for multiple applications. Controlling the coating process in-house means controlling both quality and lead time.

Coating Comparison

Why our 3-layered, pre-Galvanized product is superior

There are three ways to put zinc on a tube, and only one of them protects the inside as well as the outside. Here is how the LP Tube method compares to the alternatives.

Hot Dip After

The old way
  1. Minimal surface cleaning and temperature control means possible poor adhesion of the zinc coating.
  2. Lack of controls results in poor uniformity (pin holes) and poor adhesion of the zinc coating.
  3. Hot rolled steel surface imperfections result in a non-uniform zinc coating.
  4. The zinc surface is unprotected, resulting in white rust (zinc oxide).
  5. Only standard lengths are available.
  6. Cost factors are typically high.

Hot Dip During

Limited inside protection with an in-line process
  1. Minimal surface cleaning and temperature control means possible poor adhesion of the zinc coating.
  2. Lack of controls results in poor uniformity (pin holes) and poor adhesion of the zinc coating.
  3. Hot dip during exterior zinc application results in a non-uniform zinc coating.
  4. A zinc painted interior does not have the qualities of a pure Galvanized coating or overall corrosion protection.
  5. Clear polymer coating protects against white rust.
The LP Tube Method

Hot Dip Before

A 3-step exterior process plus a pure zinc Galvanized inside coating
  1. Continuous galvanizing of cold rolled sheet at the steel mill delivers the best possible coating adhesion, eliminating flaking and spot rusting.
  2. State of the art coating and temperature control guarantee a uniform coating that prevents pin holes and spot rusting.
  3. A hot dip Galvanized interior surface provides the best corrosion protection.
  4. A clear acrylic exterior coating plus a conversion coating gives added protection.
  5. High strength base steel allows lighter walls, resulting in lower handling and shipping costs.

Additional services

Galvanized round tubing with swaged ends for telescoping connection

Swaging

LP Tube can swage all round sizes of clear-coat Galvanized product. Tube ends are reduced about 15%, typically over a 3-inch length, so tubing can telescope into a non-swaged end for easy top-rail connection in the fencing industry.

Precision Cut-Off

For cuts closer than mill tolerances, product is moved off-line and loaded into the Modern cut-off for automatic custom cutting, delivering a superior precision end-cut.
