The Malibu Wide Plank 3/4" Thick x 5" Wide Solid Hardwood Flooring comes in random/varying lengths up to 59", the Solid Collections do not state a minimum % of Full Length planks in each case like most Malibu Engineered Hardwood collections do. The French Oak raw lumber that is used to mill the product is harvested in Europe, primarily France or Germany. This gorgeous French Oak lumber has tannins unique to the species, which allow the staining process to offer greater color depth than standard Oak flooring offers. The gorgeous reclaimed wire brushed surface texture combined with the UV low gloss factory finish, make this an excellent Solid Hardwood Flooring choice for your residential or commercial installation. If you review the French Oak 3/4" Solid Hardwood Room Scene pictures and all digital assets, you can view all black filler used for stability in this handcrafted character grade floor which uses ABCD grade French Oak Lumber. We use character grade hardwood to meet these design specifications, which may include naturally occurring cracks, splits, knotholes, mineral streaks, filler for stability, etc. By using this grade of material we are able to enhance the natural beauty of the hardwood floor you have chosen. We highly suggest reviewing all room scenes, digital assets, reviewing store samples if available, and always order online samples available for purchase.
