| Oak | Pronounced grain; available in light to medium brown tones. | Hard, wear-resistant, and widely used for durable interior doors. Its natural movement requires proper kiln drying and panel construction. | Interior room doors, entry doors in protected locations, and traditional architectural projects. | Raised-panel, shaker, carved, glazed, and contemporary slatted designs. | Clear finishes emphasize the grain; stains can produce consistent colors across mixed boards. | A versatile specification for projects requiring a familiar grain pattern and broad design compatibility. |
| Ash | Pale cream to light brown with an open, straight grain. | Strong, relatively lightweight for its strength, and suitable for shaping and steam-bending. It is generally less naturally decay-resistant than teak. | Interior doors, modern residential projects, and furniture-style entrance systems. | Flat-panel, shaker, minimalist, veneer-matched, and clear-finished doors. | Light stains and natural oils preserve its bright appearance; darker stains reduce visible color variation. | A practical choice for modern designs where a clean, linear grain is preferred. |
| Black Walnut | Rich chocolate brown, sometimes with lighter sapwood and distinctive grain variation. | Stable, workable, and valued for its appearance. It is typically selected more for premium aesthetics than maximum weather exposure. | Luxury interior doors, executive spaces, libraries, and high-end residential entrances under cover. | Large flush panels, book-matched panels, pivot doors, concealed-frame doors, and restrained carvings. | Clear matte or satin finishes are commonly used to retain depth and natural color. | Best suited to projects where natural color variation is accepted as part of the design. |
| Teak | Golden to medium brown with a typically straight or interlocked grain. | Naturally resistant to moisture, decay, and insects because of its oils; these oils can affect coating adhesion and gluing. | Exterior entry doors, coastal projects, covered outdoor openings, and premium interior doors. | Solid slab, paneled, louvered, pivot, and traditional carved designs. | Surface preparation and coating selection are important; unfinished teak naturally weathers toward silver-gray outdoors. | Confirm legal sourcing documentation and specify moisture content, joinery, and exterior coating requirements. |
| Sapele | Reddish-brown to dark brown, often showing interlocked or ribbon-like grain. | Hard, durable, and commonly used where a mahogany-like appearance is desired. Interlocked grain may require careful machining. | Exterior doors, entrance doors, interior doors, and projects requiring a warm dark finish. | Traditional raised-panel, contemporary flush, glazed, arched, and carved doors. | Dye, stain, and clear finishes can highlight the ribbon grain; sample approval is recommended. | Suitable for premium door programs when appearance consistency and responsible sourcing are verified. |
| Meranti | Pinkish brown to reddish brown, with grain ranging from straight to interlocked. | Generally workable and available in several density grades; performance depends strongly on the specific species and quality grade. | Interior doors, sheltered exterior doors, and painted or stained production ranges. | Shaker, raised-panel, glazed, louvered, and simple contemporary designs. | Paint provides a uniform appearance; stained products should be checked for board-to-board color variation. | Specify the exact botanical or commercial grade because “meranti” covers multiple related timbers. |
| Pine | Light cream to yellowish brown with visible knots and straight grain. | Lightweight, easy to machine, and economical; softer than oak or teak and more vulnerable to dents and moisture without protection. | Interior doors, cottage-style homes, utility areas, and painted door ranges. | Shaker, beadboard, barn-style, louvered, and rustic panel doors. | Paint, knot-sealing, and a suitable primer help control resin bleed and surface discoloration. | A cost-conscious option for interior use; confirm knot policy, finger-jointed content, and moisture control. |
| Paulownia | Very light-colored wood with a relatively subtle grain. | Very lightweight and dimensionally stable in many applications, but relatively soft and easily marked compared with harder species. | Lightweight interior doors, screens, decorative partitions, and projects with weight limitations. | Flush, slatted, Japanese-inspired, lightweight sliding, and decorative panel doors. | Opaque paint or clear finishes can be used; edge protection is advisable in high-traffic areas. | Confirm impact-resistance expectations before specifying it for busy commercial or entrance applications. |
