Stainless Steel Plate

Versatile Stainless Steel Plate in 304, 316L & 2205 Duplex Grades

Action Stainless supplies stainless steel plate in a wide variety of grades and thicknesses to support architectural, industrial, and structural fabrication. Stainless steel plate is a critical material across construction, manufacturing, food processing, energy, and marine sectors valued for its corrosion resistance, strength, and clean finish.


We stock a full line of 300-series austenitic stainless, including 304 and 316L, along with 2205 duplex stainless steel designed for high-strength and high-corrosion environments. Plates range in thickness from 1/8” to 4” and are available in standard widths from 36” to 120”, meeting demanding performance needs across sectors.

Finishes & Processing Services

Stainless steel plate is typically stocked in a clean, mill finish suitable for forming, welding, and machining. For applications requiring cosmetic appeal or enhanced corrosion resistance, we offer additional surface options including polished or pickled and passivated finishes. Our in-house processing services include saw cutting, plasma and waterjet cutting, shearing, forming, and custom fabrication to meet your project dimensions and tolerances. Plates can be delivered in full sheets or custom-cut sizes for efficient downstream use.

Available Styles and Materials

We stock stainless steel plate in:

  • 304 Stainless Steel Plate

    Versatile and corrosion-resistant, ideal for construction, fabrication, tanks, and processing equipment.

  • 316L Stainless Steel Plate

    Low-carbon and saltwater-resistant. Used in marine, pharmaceutical, and food-grade environments.

  • 2205 Duplex Stainless Steel Plate

    High-strength alloy with excellent corrosion resistance. Perfect for offshore, chemical, and pressure applications.

  • Mill Finish

    Clean, metallic surface for structural use or parts requiring further finishing.

  • Polished / Brushed / Pickled & Passivated Finish

    Surface-enhanced options for architectural, sanitary, or marine use. Improve appearance and corrosion protection.

Sheets are available in standard widths of 36", 48", 60", and up to 72", with lengths of 96", 120", and 144". Custom gauges and cut-to-length sizes are also available.
