Carbon Steel I Beam A36

A36 carbon steel I beams are widely used structural steel shapes for building frames, platforms, and industrial support systems. The I-shaped profile, with wide flanges and a vertical web, provides excellent strength and load-carrying efficiency.

I beam sizes are designated by two numbers, such as W10×33. The first number represents the beam’s approximate height in inches, while the second indicates the weight per foot, which helps determine strength and capacity. Flange width increases with beam size, improving resistance to bending.

ASTM A36 steel is commonly used for I beams because it offers reliable strength, good weldability, and ease of fabrication at a cost-effective price point, making it ideal for structural applications.
