Aluminum I Beams

Aluminum i-beams offer a high strength-to-weight ratio, corrosion resistance, and a slim profile. Our most popular profiles are the aluminum association i-beam (parallel flanges) and the american standard aluminum i-beam (tapered flanges), both engineered to carry heavy loads with less weight.

6061 aluminum is the most commonly specified alloy for these i-beams, providing excellent weldability, easy machinability, and long-lasting durability for construction, industrial equipment, and harsh environments.

Frequently asked questions about aluminum i beams

Are aluminum i beams as strong as steel?

Is aluminum stronger than steel? Many grades of aluminum are considered high-strength and can even compare tocertain steel alloys.

However, when comparing samples of the strongest aluminum alloy and steel alloy of the same size, steel is typicallythe stronger material.

What are aluminum i beams used for?

Aluminum I beams are commonly used in structural applications where a high strength-to-weight ratio and corrosionresistance are essential.

Are aluminum i beams expensive?

The price of aluminum I beams depends on factors such as alloy type, size, surface treatment, and market aluminumprices.

While aluminum is generally more expensive than steel per unit, it offers significant long-term cost savings due toits lightweight nature, corrosion resistance, and low maintenance requirements.

How do I choose the right size and alloy for my project?
