Premium Marine-Grade Fir Plywood (A-B Grade)

When the environment is demanding and structural integrity is non-negotiable, our Marine-Grade Douglas Fir Plywood stands as the industry standard. This isn't your average hardware store sheet; it’s a high-performance substrate engineered to withstand consistent moisture and heavy stress.

Why Marine Grade?

Unlike standard exterior plywood, Marine-Grade Fir is manufactured with zero internal Voids.

No Hidden Weakness: Standard plywood often has small gaps (voids) in the inner layers. In a marine environment, these gaps trap water, leading to rot and structural failure. Our Marine Fir uses solid-core plies to ensure maximum strength and longevity.

Waterproof Bond: The plys are bonded with a rigid phenolic resin that will not delaminate under boiling water tests or prolonged exposure to high humidity.

Best Use Cases

  • Boat Building: Hull planking, transoms, and internal cabinetry.

  • High-End Exteriors: Outdoor kitchens, signage, and decorative soffits.

  • Wet Area Subfloors: Bathrooms or laundry rooms where moisture protection is a priority.

  • Docks & Marinas: Structural decking and ramps.
