ASTM A500 Carbon Steel Structural Square Tubing
Leave a message
ASTM A500 is the US standard for cold-formed carbon steel structural tubing. This standard includes square, round, and rectangular tubing used in structural applications such as bridges and buildings. It specifies the chemical composition and mechanical property requirements for the tubing and defines four grades (A, B, C, and D), each with varying yield and tensile strengths.
ASTM A500 square tubing is a cold-formed carbon steel structural product available in both seamless and welded forms, commonly referred to as hollow structural sections, or HSS. Square tubing offers uniform strength under multiaxial loading, making it ideal for columns, and its flat surface often enhances architectural aesthetics.
