Flexible long grain ply is a type of plywood that is designed to be flexible along the long grain direction of the wood veneers that make up the panel. This makes it ideal for use in applications where a curved or rounded surface is required, such as in furniture making or boatbuilding.

Flexible long grain ply is made by laminating thin layers of wood veneers together with an adhesive, with the grain direction of each layer running in the same direction. This creates a panel that is strong and flexible along the long grain direction, while still maintaining some rigidity and stability in the cross-grain direction.

The exact properties of flexible long grain ply can vary depending on the specific type of wood used in the veneers, as well as the thickness and number of layers in the panel. Builders and designers should consult relevant industry standards and guidelines to ensure that they are using the appropriate type and grade of flexible long grain ply for their specific application.

It’s worth noting that while flexible long grain ply can be bent and shaped to some degree, it may not be suitable for extremely tight or complex curves. In these cases, specialized techniques such as steam bending or laminating thinner, more flexible veneers may be required.
