ASTM A500 rectangular tube

Rectangular tube is a hollow long steel material, also known as flat tube, flat square tube or square flat tube (as the name implies). When the bending and torsional strength are the same, the weight is lighter, so it is widely used in manufacturing mechanical parts and engineering structures.

ASTM A500 is a standard specification for seamless and weldable carbon structural steel published by ASTM International. ASTM A500 rectangular tube is a rectangular steel pipe that can be welded, riveted, or bolted for use in bridges or buildings and general structures.

D: The specified minimum elongation is only a reference value for test experiments, not a technical standard for steel pipe trade.
