Compare plywood, particleboard, and MDF as cabinet carcass materials in terms of strength and edge treatment.

• A. Plywood is cheap and easy to finish without edge banding.
• B. MDF edges do not require any edge treatment.
• C. Particleboard offers the strongest edge and no edge banding is needed.
• D. Plywood is strong with a natural grain edge; particleboard and MDF are flatter and easier to finish, but require edge banding or edge coverings; plywood edges can reveal layers.

Answer: (D)

Strength and edge treatment are the key differences when deciding on cabinet carcass materials. Plywood provides real structural strength because of its layered construction, and the edge can show those natural layers, which is why it’s described as strong with a natural grain edge. To get a clean, uniform look on the edge, you typically need edge banding or edge coverings, especially if you don’t want the veneer layers exposed.

Particleboard and MDF, on the other hand, are flatter and easier to finish across large faces because they have uniform, smooth surfaces. However, their edges are not as durable as plywood’s veneer layers, so they usually require edge banding or edge coverings to create a clean edge and protect the material from moisture and damage. MDF edges can be painted to a very smooth finish, but without edge banding, the edges can look rough or reveal the edge material, especially if you’re using a veneered or laminated surface elsewhere.

So the best summary is that plywood combines strength with an edge that shows layers, while particleboard and MDF offer flatter, easier-to-finish edges but typically need edge banding or edge coverings to finish cleanly.
