Steel vs Aluminum Expanded Metal: What to Choose
What Is Expanded Metal?
Expanded metal is made by cutting and stretching a solid sheet into a pattern of openings. It remains a single continuous piece, making it stronger than welded mesh. The result is a material that is strong, lightweight, and allows airflow and visibility.
It comes in two types:
- Raised for grip and traction
- Flattened for a smooth surface

Steel can be painted or galvanized to protect against corrosion.
Aluminum Expanded Metal
Aluminum is best when weight and corrosion resistance matter.

Common Names We Hear for Expanded Metal
Expanded metal is often called different things depending on how people use it. Many customers refer to it by the application instead of the material itself.
You might hear it called:
- BBQ grill material
- Trailer mesh or trailer flooring
- Metal screen
- Catwalk or walkway mesh
- Security mesh
These terms usually refer to the same product. Expanded metal is widely used, so the name often changes based on the job.
Conclusion
Expanded metal is a practical choice for both industrial and architectural projects. Choosing steel or aluminum depends on strength, weight, and environment. Steel Supply carries both and can help you find the right option.
