Mahogany is synonymous with exterior doors. The reason is because mahogany is a very beautiful, stable, durable and rot resistant wood. Genuine mahogany sometimes called Honduras Mahogany (scientific name: Swietenia macrophylla) is generally considered the king of the mahoganies. The radial, tangential and volumetric shrinkage of genuine mahogany is very low which makes it a great choice for the manufacture of exterior doors or interior doors.
Other mahoganies that are also used extensively in the manufacture of doors include African mahogany (scientific name: Khaya), sapele mahogany (scientific name: Entandrophragma cylindricum), and meranti mahogany (scientific name: shorea). These mahoganies have similar characteristics as Honduras mahogany.
