It's set automatically by the total weight of your order, not something you choose. Orders up to about 15,000 lbs ship hot shot (pickup truck + flatbed/gooseneck trailer). Heavier orders up to about 47,000 lbs ship by semi truck (tractor + flatbed/step-deck, full truckload of bundles).

Grade A is perfect: no defects of any kind, no splits, windows, or bowing, no ring welds. Grade B has minor defects only: good ring welds, splits 24 inches or less, all pieces within 12 inches of each other in length. Grade C is worse than B: windows present, poor ring welds, splits exceeding 24 inches, bowed pieces, length variance over 12 inches. OS (Overstock) applies to round pipe only: it has defects that keep it out of Grade A, but contains at least one 7 ft section of A-quality pipe.

We stock round tubing, square tubing, and rectangular tubing across a wide range of sizes, from small round pipe up to large-diameter structural tubing. Call or request a quote and we'll confirm exact sizes and availability for your project.
