Low-Carbon Steel I-Beams
- Yield Strength: 50,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Fabrication: Hot Rolled
- Specifications Met: ASTM A992
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.

Multipurpose 6061 Aluminum I-Beams
- Yield Strength: 35,000 psi
- Hardness: Brinell 95 (Soft)
- Temper: T6
- Fabrication: Extruded
- Specifications Met: ASTM B221
Also known as American Standard I-Beams, these I-beams havetapered flanges with rounded corners. The most widely used aluminum, 6061 is fabricated into everything from pipe fittings and containers to automotive and aerospace parts. It is strong and corrosion resistant, plus it's easy to machine and weld.
