Plywood and blockboard are both types of engineered wood that are commonly used in furniture making, construction, and other applications.

However, there are some key differences between the two materials.

Plywood is made from thin sheets of wood veneer that are glued together in layers, with the grain of each layer running perpendicular to the grain of the layer below it. This creates a strong and stable material that resists warping and cracking. Plywood is available in a range of grades and thicknesses and can be used for a wide variety of applications.

Blockboard, on the other hand, is made from a core of solid wood strips that are sandwiched between two layers of plywood or MDF (medium-density fiberboard). The core strips may be arranged in a horizontal or vertical orientation, and the surface layers are usually thinner than those of plywood. Blockboard is typically used for furniture making, particularly for shelves, cabinets, and other large, flat surfaces.

Here are some key differences between plywood and blockboard:

1. Strength and stability: Plywood is generally stronger and more stable than blockboard, due to its multi-layered construction. It is less likely to warp or crack over time.
2. Weight: Blockboard is generally lighter than plywood, due to its hollow core. This can make it easier to work with and transport.
3. Cost: Blockboard is generally less expensive than plywood, particularly for large, flat surfaces. However, high-quality blockboard can still be more expensive than low-grade plywood.
4. Appearance: Plywood has a more uniform appearance than blockboard, due to its multiple layers. It is also available in a wider range of finishes and veneers. The blockboard may have visible seams or gaps between the core strips.

In summary, plywood and blockboard are both useful materials for a variety of applications, and the choice between them will depend on factors such as strength, weight, cost, and appearance. There are different grades available for both which you can find at Ply Story!
