The cabinet carcase is usually made from plywood or high-quality particle board, particularly for flat sections that do not need to be shaped, such as shelves, cabinet sides, or drawer bottoms. Typical plywood thickness in these applications varies from 9 mm to 18 mm.Stiffness and strength are important factors since cabinets are expected to retain their shape over time and avoid bend or sag while continuing to support a heavy load.


The best choices for strength are plywood and higher-quality particle board; they also have the benefit of being less susceptible to warping from moisture. Stiffness increases rapidly with shelf thickness; regardless of material choice, a18 mm shelf is 73% stiffer than a 15 mm shelf, even though it is only 20% thicker. Shelves made of some particle board formulations, especially where not reinforced, may sag or deform. Particle board strength and rigidity varies by formulation and is determined by the resin used.

Plywood carcases are usually assembled with screws and nails while particle board carcases do not hold screws or nails as well and therefore are typically joined with glue, groove joints, or mechanical fasteners such as confirmat-cam assemblies. Generally, plywood-carcase cabinets are more expensive than particle-board-carcase cabinets.
