3003 Aluminum Diamond Plate

3003 Aluminum Diamond Plate

3003-H14 Aluminum Diamond Plate meeting ASTM B209. Lightweight, non-slip, and highly formable with excellent corrosion resistance. Thicknesses from 0.063" to 0.250" in stock.

About 3003 Aluminum Diamond Plate

3003-H14 aluminum diamond plate provides a lightweight, non-slip surface with excellent corrosion resistance and formability. Conforms to ASTM B209. Ideal for trailer flooring, wainscoting, and protective paneling.

Quick Facts

  • Material: 3003 Aluminum
  • ASTM Standard: B209
  • Temper/Condition: H14 (Strain-hardened)
  • Available Sizes: 0.063", 0.125", 0.188", 0.250" thickness
  • Location: Los Angeles warehouse
  • Services: Custom size, same-day pickup

Overview

3003 aluminum is a commercially pure alloy with manganese added for increased strength, delivering approximately 20% more strength than 1100 grade. The H14 temper signifies it has been strain-hardened and partially annealed. This results in a material that is easy to form, drill, and weld. The raised diamond pattern provides excellent skid resistance and rigidity, making it a functional and durable choice for various applications.

Known for its excellent workability and weldability, 3003 diamond plate is a popular choice for general fabrication. While not heat-treatable like 6061 aluminum, its properties are ideal for applications not requiring high mechanical strength. The bright, reflective finish combined with the textured pattern provides a clean, modern aesthetic suitable for both protective and decorative uses, performing well in various environments without rusting.

Technical Specifications

⚠️ Reference Data Only: Values shown are typical industry standards and may vary by manufacturer, lot, and heat treatment. For critical applications, please contact us to verify specifications or request a Mill Test Report (MTR).

Applicable Standards

  • ASTM B209: Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate

Common Applications

  • Automotive/Transportation: Trailer flooring, running boards, and toolbox lining - for durability and non-slip surface.
  • Architectural: Wainscoting, wall paneling, kick plates, and corner guards - for protective and aesthetic purposes.
  • Industrial: Stair treads, catwalks, ramps, and platforms - to create safe, high-traction walking surfaces.
  • Marine: Decking, dock plates, and gangways - for its excellent corrosion resistance in wet environments.
  • Food Service: Kitchen backsplashes and wall coverings - as it is easy to clean and resists corrosion.
  • Commercial: Retail displays, counter fronts, and decorative trim - for its modern, industrial appearance.

Working with 3003 Aluminum Diamond Plate

Machining

3003 aluminum has fair machinability. It can be somewhat gummy compared to harder alloys like 6061. Use sharp tools, high speeds, and proper lubrication for best results. The diamond pattern may require secure clamping for precision work.

Welding

This alloy has excellent weldability using common methods like TIG (GTAW) and MIG (GMAW). AL4043 filler wire is typically recommended for best results and to minimize the risk of cracking.

Finishing

The material is supplied with a standard mill finish and a raised diamond pattern. It can be anodized for increased corrosion resistance and color options, or polished for a brighter, more reflective appearance.

Frequently Asked Questions

Q: What is the difference between 3003 and 6061 aluminum diamond plate?

A: 3003 is softer, more formable, and has better general corrosion resistance. 6061 is significantly stronger (45,000 PSI vs 22,000 PSI tensile strength) and is heat-treatable, making it suitable for structural applications where strength is critical.

Q: Can 3003 diamond plate be bent?

A: Yes, 3003-H14 has excellent formability and can be bent to a tight radius without cracking, making it ideal for custom fabrications like boxes, trays, and corner guards.

Q: Is the thickness measured from the base or the top of the diamond?

A: The specified thickness (e.g., 0.063") refers to the nominal thickness of the base plate material, not including the height of the raised diamond pattern.
