Five-piece hardwood doors are composed of a central panel surrounded by four frame pieces—two vertical stiles and two horizontal rails. This door construction method is known for its strength, stability, and classic aesthetic appeal. The central panel, typically made of solid hardwood or veneer, is recessed to allow for natural expansion and contraction of the wood, which helps to prevent warping over time. The frame itself is made from high-quality hardwoods such as oak, maple, or cherry, which are selected for their strength, grain patterns, and ability to withstand wear. These doors can be finished with stains, paints, or natural wood treatments to highlight the material’s texture and color.
