- Birch Lumber ^ return to product lines

Birch lumber is a high quality hardwood that we supply after it has been harvested from some of the world’s finest stands of timber and kiln dried and processed by expert manufacturers. The coloring is mostly creamy white, but as it nears the core will show brown flame patterns with white sap edges. The texture is fine and uniform. The wood can easily be glued, stained, and polished, due to its closed pore structure, and is also characterized by a high banding and crushing strength. Applications include high-end furniture, upholstery frames, cabinetry, millwork, and flooring, among others.

We offer Birch lumber KD in various dimensions and grades and can also custom manufacture in accordance with your specifications. Please contact us to discuss your specific needs.
