I-Shaped Aluminum Bar: Properties, Uses, and Benefits

I-Shaped Aluminum Bar: Properties, Uses, and Benefits

If you’re curious about I-shaped aluminum bars, you’ve come to the right place. They put a super lightweight yet heavyweight spin on traditional structural shapes. They are resistant to corrosion plus the strength to weigh 80% less than equally tough steel counterparts. In this article, we will help you learn everything you need to know about these little metal bars. From what they’re made of to how they’re used, we will help you understand more. So let’s get started.

What are I-Shaped Aluminum Bars?

I-shaped aluminum bars are exactly what they sound like-aluminum bars that are shaped like the letter “I”. They are made from high-quality aluminum alloys, with the most common ones being 6061 and 6063. These alloys are known for their strength, durability, and corrosion resistance, making them perfect for a wide range of applications.

Advantages of I-Shaped Aluminum Bars

There are a few reasons why I-shaped aluminum bars are so reliable. For starters, they are super lightweight. This makes them perfect for applications where weight is a concern, such as in the aerospace and automotive industries. Despite being lightweight, they’re also incredibly strong due to their high strength-to-weight ratio. This makes them perfect for applications where strength is a priority, such as in construction and manufacturing.

Another great thing about I-shaped aluminum bars is that they’re corrosion-resistant. This means that they won’t rust or corrode, even when exposed to the elements. So whether you weld giant warehouse racks, craft custom racecar trailers, follow along digesting why intelligently designed I-beam aluminum bars dominate for designers strategizing lightweight toughness into the equation.

Global Specs to Reference

While custom I-shaped dimensions abound for unique applications, catalog standard references help guide sourcing for production work:

ASTM B308: Defining US alloys, tolerances, and testing procedures verifying consistent chemistry and quality conformance across general-purpose I-bar supply chains.

EN 755-9: European standards outlining regional I-beam variants like higher purity special German alloys.

JIS H 4100: Japanese specifications with a focus on earthquake resilience across high seismic activity regions. Western spec I-beams are often imported as well as fitting regional builds.

With reliable I-bar sources offering validated strengths and quality baseline assurances, engineers confidently progress designs to fabrication benefiting lightweight aluminum mechanical advantages meeting applicable regional codes and practices for sustained safety margins.

Common I-Shaped Aluminum Bar Dimensional Guidance

Dimensions span from 400mm deep section heights available in common increments. Ranging from miniature electronics chassis all the way to robust bridge stringers and mining equipment reinforcement frames. Thicknesses typically run 3mm to 16mm for flanges and web plates:

150 x 75 x 12mm: Medium-duty shelf framing and workbench components

250x 200 x 25mm: Structural alloy wrapped around porch posts and staircase stringers

400 x 200 x 25mm: Heavy equipment bed framing, truck chassis, and towable axle components

No worries about custom or non-standard I-shaped aluminum bars. Just budget a little more lead time from order to delivery.

I-Shaped Aluminum Bars Applications

They are used in a wide range of applications due to their unique combination of properties. Here are a few examples of how they are used:

They are used in the construction of buildings, bridges, and other structures. Their lightweight and strength make them perfect for applications where weight needs to be dealt with, such as in high-rise buildings and long-span bridges.

I-shaped aluminum bars are used in the aerospace and automotive industries. They are used in the construction of cars, aircraft, and other vehicles.

Due to their strength, durability, and corrosion resistance, I-shaped aluminum bars are being used in the manufacturing of a wide range of products, from furniture to industrial equipment.


I-shaped aluminum bars are a versatile and practical material that is used in a wide range of applications. Whether you’re building a bridge, a boat, or a piece of furniture, I-shaped aluminum bars are a great choice. So, the next time you require a strong and lightweight material, consider using I-shaped aluminum bars. Feel free to reach us at YK-Longshun to learn more about our different aluminum products.
