Our 18mm marine plywood is engineered to endure demanding outdoor applications, from boat-building to docks, trailer beds, and heavy-duty construction projects.
Every component of our marine plywood is designed for strength and moisture resistance. It uses high-grade hardwood veneers that resist fungal decay. A waterproof adhesive bonds the layers to prevent delamination, even after years in the elements. Minimal gaps between veneers act as a barrier against water absorption.
The 18mm thickness provides extra rigidity and stability for a solid building foundation. The added thickness also allows for clean cuts, drilling, and hardware installation without splitting. The cross-banded construction minimizes wood grain misalignment for splinter-free edges.
Marine plywood is perfect for damp areas prone to splashing or spills like bathrooms, laundry rooms, kitchens, wet bars, and pool houses. For boat-building and waterside structures, marine plywood far outlasts standard plywood.
The thick 18mm plywood offers pronounced structural integrity for heavy-duty applications like workbenches, scaffolding, stage platforms, and trailer beds. It provides sturdy support without excessive weight.
Our marine plywood surpasses standard plywood in strength, water resistance, and reliability. The layered construction resists delamination, warping, and fungal decay better than standard plywood. For marine and outdoor use, marine plywood is the clear choice.
For heavy-duty construction projects
Around areas exposed to moisture:
For structural support and stability:
Material | Plywood |
Finish | Marine |
Thickness | 18mm |
Maximum Sheet Size | 2420mm x 1220mm |
Minimum Sheet Size | 100mm x 50mm |
Plywood Grade | BB/BB |
Manufacturers Tolerances | +/- 10 % plus 0.4mm (e.g. 5mm cast sheet could vary from 4.1mm to 5.9mm) |
Cutting Tolerances | +/- 1mm |
Consider your project. For light crafts, use 4mm ply. For cabinet backs, 6mm plywood. For furniture and shelves, 9mm ply to 12mm plywood should be used, based on load needs. For heavy-duty uses like flooring, we suggest using 18mm ply board.
No, but it has minimal gaps between layers to reduce water absorption. This provides strength.
It uses better wood, more layers, durable adhesive, and resists delamination and warping in wet conditions, unlike regular plywood.
Use a penetrating waterproof epoxy, as it soaks deep into the wood and needs less maintenance.
Anywhere your plywood will be near water since marine plywood is designed for moisture resistance.
With care, over 25 years even with constant water exposure. Sealing and painting increase lifespan.
No, it gets water resistance from quality wood, adhesive, and laminated layers - not chemicals.
Delivery depends on the size of your order
