    High-Strength A992 Alloy Steel I-Beams

    Image of Product. Front orientation. Steel. High-Strength A992 Alloy Steel I-Beams.
    Made of stiff alloy steel, these I-beams are often used in construction, framing, lifting, and hoisting applications. Alloy steel contains silicon and vanadium to boost strength and hardness, so it bends less under load than carbon steel. 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.
    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 304 Stainless Steel I-Beams

    Image of Product. Front orientation. Stainless Steel. Multipurpose 304 Stainless Steel I-Beams.
    I-beams are lighter weight than H-bars, but they're not as strong. Use them when weight is a concern. 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.
