    Sheet Metal Materials

    Aluminum 5052

    Characteristic: Aluminum 5052 offers excellent corrosion resistance and formability. With more magnesium than 6061, it’s easy to weld and machine, making it great for marine and chemical applications.

    Lead Time: As fast as 2 days

    Finishing Options: Anodizing, Hardcoat Anodizing, Powder Coating, Silkscreen, Laser marking. Learn more >

    Stainless Steel 201

    Characteristic: Stainless steel 201 offers moderate resistance to acids and alkalis, features high density, and exhibits excellent surface finish with no visible porosity or pinholes after polishing.

    Lead Time: As fast as 2 days

    Finishing Options: Brushing, Powder Coating, Silkscreen, Laser marking. Learn more >

    Stainless Steel 304

    Characteristic: Stainless steel 304 offers high temperature resistance up to 800°C, good processing performance, and high toughness.

    Lead Time: As fast as 2 days

    Finishing Options: Brushing, Powder Coating, Silkscreen, Laser marking. Learn more >

    Cold Rolled Steel

    Characteristic: Cold Rolled Steel offers high-precision dimensions, excellent surface smoothness, and superior deep-drawing capabilities while requiring protective coatings against oxidation due to its unprotected surface.

    Lead Time: As fast as 2 days

    Finishing Options: Powder Coating, Silkscreen, Laser marking. Learn more >

    Galvanized Steel Sheet

    Characteristic: Galvanized steel sheet offers excellent corrosion resistance and decorative appearance while maintaining the workability of cold-rolled steel, featuring a thicker zinc coating than electro-galvanized alternatives, though with reduced weldability and formability, making it ideal for construction, appliances, and automotive applications where durability outweighs deep-drawing needs.

    Lead Time: As fast as 2 days

    Finishing Options: Powder Coating, Silkscreen, Laser marking. Learn more >

    Sheet Metal Surface Finishes

    • Standard

      Parts are machined and deburred with no additional surface finish. Visible machining marks, light surface scratches.
    • Anodizing

      Anodizing creates a corrosion-resistant, uniform, matte or glossy finish. Parts can be anodized in different colors—black, red, and gold are most common.
    • Hardcoat Anodizing

      A type of anodizing that produces a thicker and harder coating on the surface, resulting in increased wear resistance and durability.
    • Conductive Anodizing

      An anodizing process that creates a conductive oxide layer on the surface, typically used for EMl/RFl shielding or electrical grounding applications.
    • Powder Coating

      Electrostatic dry powder application cured under heat. Eco-friendly, durable finish with superior corrosion resistance for metal parts.
    • Brushing

      Parts are brushed using an abrasive tool to create a pattern of fine parallel lines on the material surface, producing a unique aesthetic effect.
    • Silkscreen

      A part marking technique that uses a fine mesh screen to apply ink onto a surface, to print the desired text or image onto the substrate.
    • Laser Marking

      Laser marking uses a laser beam to create permanent marks or designs on the surface of a material, typically resulting in high precision and resolution.
