Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications. Low carbon steel deflects less under load than medium- or high-carbon steel and is less likely to crack from welding—no wonder it's the standard for I-beams. For added wear resistance, they can be surface hardened with heat treating. Also known as American Standard I-beams, these I-beams have rounded corners. All have been manufactured to meet ASTM A992 standards for quality and performance.

The beam trade number indicates the I-beam's outside height and weight in pounds per foot. This provides an easy reference to help you select the right size and strength for your application.
