Aluminum Coil

Versatile Aluminum Coil in 1100, 3003, 5005, & 6061 Grades

Action Stainless supplies aluminum coil in a wide variety of grades, widths, and tempers to meet the demands of marine builders, architectural fabricators, and general manufacturers. Aluminum coil is a flexible, corrosion-resistant material ideal for forming, bending, shearing, and coating processes. It’s commonly used in everything from boat cladding and trailer skins to decorative panels and utility enclosures.


We supply aluminum sheet in 1100, 3003, 5005, and 6061 grades, each chosen for its unique combination of formability, surface finish, strength, and resistance to marine environments.

Finishes & Processing Services

Aluminum coil is typically stocked in mill finish, making it ideal for industrial forming and fabrication. For applications that call for enhanced protection or visual appeal such as marine or architectural use, we also offer anodized and painted finishes, including custom color options. Coil can be processed to meet your exact project needs with in-house capabilities like slitting, cut to length, coil leveling, shearing, and brake forming. Material can be delivered in full rolls or pre-cut sizes, ready for use in both structural and decorative applications.

Available Styles and Materials

We stock aluminum coil  in:

  • 1100 Aluminum Coil

    Commercially pure aluminum with excellent corrosion resistance and superior formability. Often used in non-structural marine trim, interior panels, and lining where flexibility and a clean finish are key.

  • 3003 Aluminum Coil

    An aluminum-manganese alloy that offers moderate strength and good workability. Suitable for interior wall panels, cabinetry, and decorative components on boats and marine trailers.

  • 5005 Aluminum Coil

    A marine-grade alloy ideal for exterior boat components and architectural marine detailing. Known for excellent corrosion resistance and color-consistent anodizing, making it a top choice for hull skins, side panels, and trim exposed to saltwater.

  • 6061 Aluminum Coil

    A high-strength, heat-treatable alloy commonly used in structural framing, supports, and fabricated marine parts. Provides reliable weldability and resistance to marine conditions.

  • Mill Finish

    Standard unfinished aluminum with a clean, metallic appearance. Ideal for marine fabrication where post-processing like anodizing or painting will be applied.

  • Brushed/Bright/Anodized Finish

    Enhanced surface treatments for boats and marine structures. Brushed and bright finishes offer sleek, decorative appeal, while anodized finishes improve corrosion resistance and are perfect for exposed saltwater environments.

Coils can be delivered in slit, leveled, or full-roll form to match your production or job-site needs. We also offer custom packaging to ensure safe transport and easy handling on arrival.
