American Walnut Timber Veneer Panel A/B UV-Coated FOSB 19x1220x2745mm is an FOSB panel overlaid with A/B crown-cut, randomly mismatched American Black Walnut veneer.
American Black Walnut is a premium North American hardwood known for its rich golden to chocolate-brown heartwood, sometimes featuring darker purplish-brown streaks. Its pale creamy sapwood and fine, generally straight grain create a refined natural contrast, while occasional wavy or curly figure adds decorative character.
Valued for its appearance, stability and workability, American Black Walnut machines, sands and finishes well, making it an excellent choice for high-end cabinetry, furniture, joinery, decorative panels, boiserie, carving, and detailed interior applications.
The panel features a wire-brushed surface that introduces refined tactile texture and enhances the play of light across the timber grain. Supplied fully prefinished, the panels arrive ready for installation with no on-site sanding, staining, or coating required. The surface has high resistance to scratches and micro-abrasion. Made from sustainably sourced timber, it offers an environmentally responsible option for modern interiors.

Natural timber veneer colour and grain disclaimer
Timber is a natural material, and variation in colour, grain, texture, figure and tone is expected. Samples are provided as a general indication only and cannot represent the full natural variation of the supplied product.
The final panels supplied may, and likely will, differ from the sample in colour, grain pattern, contrast and overall appearance. This is not considered a defect, as each timber veneer sheet is unique and reflects the species' natural characteristics.
