Rectangular & Square Tubing

Chatham Steel is a leading steel distributor offering a wide variety of structural steel tubing in rectangular and square shapes and numerous sizes. Rectangular and square tubing is an integral component of the construction industry. These structural steel products provide excellent strength in an orthogonal cross section, making them ideal for welding, equipment fabrication, and structural construction projects. Chatham Steel also carries proprietary steel tubing also known as “prop tube” in the steel industry. Prop tubing refers to large dimension rectangular and square tubes produced by only a few manufacturers in the country. As a leader in steel processing services, Chatham Steel supplies its customers with all types of steel tubing including ASTM A500 and ASTM A847 rectangular and square carbon steel structural tubing.

Chatham has a depth of inventory in carbon steel tubing, which translates to fast turnaround for you. At Chatham we carry the common as well as the difficult to find Hollow Structural Steel sizes in incremental lengths. In many sizes, we stock the following lengths: 28′, 32′, 36′, 40′, 44′, 48′, 52′, or 60′. We are constantly adding additional HSS sizes and lengths so be sure to inquire for your specific job requirements. We will nest your lengths with our inventory and make you a cut sheet with your piece marks or cut it to length and piece mark them for you. Let us minimize your waste on your HSS requirements. We also stock tube in galvanized, stainless, and aluminum. And if there’s a special item we don’t have, we’ll find it quickly and easily, so there’s no worry for you.

From fast turnaround to precision cut-to-length services, we’ve got it all. And, with our extensive mill and vendor contacts, Chatham also has the resources that make your non-standard inquiries no problem at all. Mill Test Reports are available.

Steel Tubing Products

A500 TUBING: Made from flat-rolled steel, ASTM A500 structural tubing is welded with an advanced ERW welding system to ensure a reliable seam. Welded steel tubes are produced via an ERW welding process where a continuous weld seam joins the edges of the folded plate.

ASTM A847 TUBING is typically left unpainted. Over time, the surface develops a protective layer of rust that inhibits further corrosion. The added structural efficiency of A847 Steel allows for a lighter wall thickness than what would be needed for carbon steel tubing.

CARBON STEEL TUBING is widely used for its strength, durability, and cost effectiveness.
