Aluminum Plate

Premium Aluminum Plate in 1100, 3003, 5052, & 6061 Grades

Action Stainless stocks aluminum plate in a wide range of grades, thicknesses, and sizes to meet the demands of high-performance applications. Known for its strength-to-weight ratio, machinability, and resistance to corrosion, aluminum plate is a preferred material in industries such as aerospace, marine, transportation, and tooling.


We offer plate in 1100, 3003, 5052, and 6061 grades. Each alloy is designed for specific performance characteristics and is available in both standard and custom dimensions.

Finishes & Processing Services

Aluminum plate is supplied in standard mill finish, providing a clean, as-rolled surface suitable for general use. Brushed and anodized finishes are available on select grades for architectural appeal and enhanced corrosion resistance. Our in-house processing includes precision saw cutting, waterjet and plasma cutting, CNC machining, and forming. These services allow us to meet complex project specifications with tight tolerances and fast turnaround times.
