ASTM A500 Gr A, B, C, D Structural Tubing
Emirerri Steel is a trusted supplier of ASTM A500 Structural Tubing, available in Grades A, B, C, and D. These cold-formed, welded, and seamless carbon steel structural tubes are widely used in construction, infrastructure, and engineering applications. ASTM A500 tubes are valued for their strength, durability, and cost-effectiveness, making them a preferred choice for structural purposes.
What is ASTM A500 Structural Tubing?
ASTM A500 is the standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square, rectangular, and special-shaped sections. Unlike mechanical tubing, A500 is specifically designed for structural applications where load-bearing capacity and performance are critical.
Key Features
