Selecting the right framing system is critical for efficiency, cost-effectiveness, and durability in industrial applications. Traditional steel framing has been the standard for decades, but 80/20 T-slot aluminum has emerged as a versatile alternative. Known for its modularity and ease of assembly, 80/20 offers a reconfigurable option that is both strong and lightweight—comparable in strength to A36 carbon steel.
80/20 provides a modular T-slot aluminum building system for a range of applications, from machine guarding and robotic enclosures to ergonomic workstations and automation fixtures. In this article, we compare 80/20 aluminum to steel framing to help you determine the best solution for your next project.
80/20 aluminum framing utilizes a T-slot extrusion system, allowing for customizable and scalable structures. Often referred to as an "erector set" for industrial applications, 80/20 enables engineers and designers to build, modify, and expand their projects with total ease.
Common Applications:
Key Advantages:
Steel framing is a well-established solution known for its rigidity and load-bearing capabilities. While it provides a strong and permanent structure, most modifications usually require fabrication and machining.

Companies that require modularity and adaptability benefit the most from 80/20 aluminum framing. It is an excellent choice for machine guarding and safety cells, since it can be easily customized to meet safety regulations. Ergonomic workstations also take advantage of the adjustable design, allowing businesses to tailor their setups to the needs of their workforce. 80/20 aluminum is ideal for automation and robotics applications, providing strong yet lightweight support for robotic arms and conveyors.
For applications that demand maximum rigidity and load-bearing capacity, steel remains the preferred choice. It is ideal for heavy-duty equipment support, providing structures with zero flex even under extreme loads. Steel is well-suited for fixed industrial installations where permanent frameworks are required and modifications aren’t as important.
Customer Success Story: GCG recently helped a customer convert to 80/20. This manufacturer previously relied on steel for equipment frames supporting pumps, motors, and electrical enclosures. GCG created an 80/20 prototype that was able to withstand the weight as well as cut their assembly time in half. This was a significant cost savings as well, since these frames can now come in ready to use or in kit form, depending on the customer’s time requirements.
Is aluminum strong enough for industrial applications? Yes! 80/20 aluminum has a yield strength comparable to A36 carbon steel, making it suitable for many applications.
Can 80/20 integrate with steel components? Yes. 80/20’s unique T-slot system allows for attachment to steel frames with minor machining adjustments.
How does total cost compare over time? 80/20 aluminum offers lower overall costs overall due to reduced labor, faster installation, and the ability to repurpose materials.
Both 80/20 aluminum and steel framing offer unique advantages. But if you need a modular, lightweight, and cost-effective solution, 80/20 is the ideal choice.
