Tube Randoms are tubes in our inventory of random sizes, random quantities, and random lengths. These tubes are typically drops off previous jobs, the balance of unused tubes when a mill minimum is ordered for a job, or contigency left over from a previious job. This material is not shown in our stock due to variance in our cost compared to our stock. This is a good place to look when you need short lengths or small quantities.
ERW (Electric Resistance Welded) refers to the seam welding fabrication process. The strip is trimmed, cold formed to shape, and the edges are weld prepped through a series of rollers. The prepped edges are then forced together under pressure and heated.
Seamless Tubing is manufactured from a solid round billet that is pierced and extruded. There are no welded joints or seams.
