Low-Carbon Steel I-Beams
- Yield Strength: 50,000 psi
- Hardness: Not Rated
- Heat Treatable: Yes
- Specifications Met: ASTM A992
Made of rigid low-carbon steel, these I-beams are often used in construction, framing, lifting, and hoisting applications. Also known as mild steel, low-carbon steel is the most commonly used material for I-beams. It deflects less under load than medium- or high-carbon steel and is less likely to crack from welding. These I-beams have rounded corners, and are also known as American Standard I-beams. They weigh less than low-carbon steel H-bars, but are not as strong.

Multipurpose 304 Stainless Steel
From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
Bars with sheared edges are also known as Gauer bar and are sheared from plate.
I-beams are lighter weight than H-bars, but they're not as strong. Use them when weight is a concern.
