We can build most of our mantels from any type of wood (Poplar, Oak, Maple, Cherry, Beech, Mahogany, Pine, Cypress, Alder, Birch, Walnut, etc.). There is an extra charge for stain grade materials.  We use Poplar for our paint grade applications but Poplar also stains very well and is no extra charge for stain applications.  In some of our bigger mantels we use plaster pieces for some of the decorative mantel parts.  The species available are listed by each mantel in the "details" pages.
