Chemical Analysis
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.
Square & Rectangle Tubing
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.

Specification Notes
● 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.
