ASTM 500 steel is primarily used to make what?

ASTM A500 is a specification that covers cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. The primary use of ASTM A500 steel is in the manufacturing of structural steel tubing, especially square tubular steel. This material is favored in construction and structural applications due to its strength, versatility, and ability to be treated and formed into various shapes.

The specification details the structural and mechanical properties that ensure the tubing meets the necessary requirements for various applications, making it an excellent choice for materials that will bear loads and withstand significant structural stresses. Square tubing made from ASTM A500 can be found in several applications across the construction and manufacturing sectors, reinforcing its significance in structural engineering.
