Aluminum Expanded Metal 

Variety of Aluminum Expanded Metal in 1100, 3003, & 6061

Action Stainless offers aluminum expanded metal in a range of mesh sizes and styles to support industrial, architectural, and safety applications. Expanded metal is produced by slitting and stretching aluminum sheet into a rigid mesh with diamond-shaped openings. It provides excellent strength-to-weight ratio, ventilation, and slip resistance.



Aluminum expanded metal is ideal for walkways, screens, security partitions, infill panels, and protective guards. It combines corrosion resistance, durability, and versatility in a cost-effective solution.

Finishes & Processing Services

Aluminum expanded metal is typically stocked in mill finish, suitable for industrial and structural use. We also offer anodized and powder-coated finishes for corrosion protection and aesthetic enhancement in architectural applications.

Processing options include shearing, plasma cutting, and bending to meet project-specific shapes and sizes. Expanded metal can be supplied in full sheets, cut-to-size, or framed panels depending on your application.

Available Styles and Materials

We stock aluminum expanded metal in both:

  • Standard (Raised)

    Offers maximum rigidity and traction

  • Flattened

    Provides a smoother surface for aesthetic or handling purposes

Standard mesh sizes include 1/4" to 1-1/2" diamond patterns with variable strand widths and thicknesses. Custom sizes and mesh configurations are available upon request.
