Thick veneer is the wood veneer sheet with thickness more than standard veneer thickness 0.4mm, 0.5mm, 0.55mm, or 0.6mm.
Usually, the common thick veneer can be 0.8mm, 1.0mm, 1.5mm, 2mm, 3mm, and 4mm.
And the most popular thick wood species are Oak, Walnut, Sapele, Teak, Cherry, Maple, and Bamboo.
Instead of natural wood, you can choose engineered wood for any thickness.
If the thickness is less than 2mm wood veneer, they are sliced cut. For 3mm or 4mm thick wood veneers, they are saw cut.
Most of the thick wood veneer is for furniture, engineered hardwood flooring, and thick veneered plywood.
