The A500 series of American standard rectangular and square tubes are square and rectangular tubing produced according to the ASTM A500 standard, commonly used in structural engineering. This series of tubing offers excellent strength and durability, making it a material for multiple fields such as construction, bridges, and machinery manufacturing. Its main specifications cover a wide range of rectangular and square tube sizes to accommodate different design requirements.
