Marine plywood is the ideal choice when you need a material that can withstand the rigors of environmental conditions, especially those involving moisture. It combines strength, durability and water resistance for a wide range of demanding applications, ensuring long-lasting performance in even the most challenging environments.
Marine plywood is a high-quality plywood designed for environments exposed to moisture, humidity, and other harsh conditions. It is made from durable hardwoods, with layers bonded together using a waterproof adhesive that will not delaminate in wet conditions. It is commonly used in marine applications, but its durability and water resistance make it suitable for a variety of other uses as well.
Main Features
- Waterproofness
Marine plywood is bonded with a waterproof glue, usually phenolic, which ensures that the wood veneer layers remain firmly bonded even when exposed to water. Plywood is treated with preservatives to increase its resistance to fungal and insect attack.
- Flame Retardancy
Flame retardants are added during the production of marine plywood to slow its burning rate when exposed to a fire source, reducing the risk of fire.
- Durability and High Strength
The veneers used in marine plywood are generally of high quality with minimal defects, ensuring uniform strength and durability. It is usually made from hardwoods such as oak or birch, which are known for their resistance to water and decay. The layers are carefully arranged with alternating grains to minimize warping, twisting and swelling.

Common Applications
- Shipbuilding
Marine plywood is widely used in the construction of boats, yachts, and other marine vessels. It is used for hulls, decks, bulkheads, and other structural components that need to withstand continuous exposure to water.
- Piers and Bridge Piers
Marine plywood is a popular choice for the construction of piers, bridge piers, and other waterfront structures due to its resistance to water and severe weather conditions.
- Outdoor Furniture
Marine plywood is used in the manufacture of outdoor furniture, especially in environments where the furniture will be exposed to rain, humidity, and temperature fluctuations.
- Exterior Cladding
Exterior cladding for buildings and structures where moisture resistance is critical, such as coastal areas or areas with high rainfall.
- Kitchen and Bathroom Cabinets
Marine plywood is often used in kitchen and bathroom cabinets because of its ability to withstand the moisture and humidity common in these areas.
- Partitions and Panels
In the construction of mobile homes, RVs, and other portable structures, marine plywood is used for partitions and panels where strength and moisture resistance are required.
