What is the ASTM A500 pipe?

Superior construction projects require materials that can withstand numerous environments and a variety of extreme conditions. High strength A 500 carbon steel structural tubing from Totten Tubes provides the high-end framework and skeletal support for projects of all sizes. Such as carbon steel round tubing, carbon steel square tubing, carbon steel rectangular tubing. And “special” carbon steel shapes for welded, riveted, or bolted construction applications, as well as for general structural purposes.

ASTM A500 specification covers welded and seamless carbon steel tubing in round, square, rectangular, and “special” shapes for construction and structural purposes.BESTAR supply and stock square, rectangle, round and special shaped electric resistance welded (ERW) carbon steel tubing to meet ASTM A500 Grade A, Grade B and Grade C used for structural applications.

Product size of ASTM A500 tube

Square & Rectangular tube

Below are physical properties required to meet the three grades that we produce ASTM A500 square, rectangle and special shaped tubing to. A flattening test is not a standard requirement for non-round tubing produced to A500.

Grade B46,000 psi58,000 psiDetermined by wall
Grade C50,000 psi62,000 psiDetermined by wall

 Round tube

Below are physical properties required to meet the three grades that we produce ASTM A500 round tubing to.  A flattening test is also a standard requirement for round tubing produced to the A500 specification.

● According to ASTM A500, the weld seam location for square, rectangle and other specially shaped tubing shall not be located within the corner radius, unless specified by the customer or manufacturer.

● Under ASTM A500, the corner radius for square and rectangular tubing shall not exceed three times the corner radius.

● As a standard under ASTM A500, electric resistance welded tubing is normally provided without removal of inside flash. If flash control is required, please specify at time of quotation or order placement.

● ASTM A847 is a related structural specification that covers high-strength low alloy atmospheric corrosion-resistant steel tubing. Please refer to the ASTM A847 page for more information.

● For more detailed information on the A500 specification and to purchase a copy of it, please visit the ASTM website.
