ASTM A500 SHS square Hollow Sections Steel

Product Description

ASTM A500 Square and rectangular tubes

Our ASTM A500 Square and Rectangular Steel Tubes are cold-formed carbon steel structural hollow sections manufactured to ASTM A500 / A500M specifications—the industry standard for structural tubing used in bridge and building construction, as well as general structural applications.

Available in Grade B and Grade C, with Grade C being the predominant material offering 50 ksi (345 MPa) minimum yield strength—the highest strength level in the standard. Most domestic production features dual-certified Grade B/C material, allowing maximum design flexibility

These tubes are produced using the electric-resistance welding (ERW) process, where flat steel sheet is cold-formed into shape and welded under pressure and strong electric current. The cold-forming process delivers superior dimensional accuracy, consistent mechanical properties, and excellent strength-to-weight ratios, making them the preferred choice for load-bearing structural applications
