  • ASTM A500

    ASTM A500 is a specification set by ASTM International for cold-formed welded and seamless carbon steel structural tubing. It covers tubing in various shapes, such as round, square, and rectangular, used primarily in structural applications. ASTM A500 steel tubing is designed to provide good mechanical properties and durability while remaining cost-effective. Its versatility and strength make it a key component in construction, infrastructure, and industrial projects.

    Types of ASTM A500 Steel Tubing

    Square Tubing

    Square tubing is commonly used in structural applications such as building frames, supports, and columns. Its uniform shape offers stability and strength

    Rectangular Tubing

    Rectangular tubing is often used in load-bearing structures where a high strength-to-weight ratio is required. It provides greater surface area for attachments and reinforcements.

    Round Tubing

    Round tubing is widely used in mechanical and construction applications. It offers good structural integrity and is easy to manufacture and weld.
