Compared with ordinary market plywood, multi-layer plywood has small deformation, large strength, good internal quality (small holes after sawing, no layering), good flatness, and can produce 5-40mm thick, multi-layer solid wood board is made of high-quality solid wood veneer or science and technology wood as the substrate, through several processes such as cold pressing, hot pressing, sanding, and curing.

Multi-layer solid wood floor is composed of solid wood surface layer and solid wood base layer. The quality of the surface layer determines the beauty and service life of the floor. The surface layer is made of selected high-quality wood after several processes of drying, degreasing and curing. The surface should be free of defects such as decay, dead knots, wormholes, cracks, skin clips, etc., but for small knots, the color difference should not be too strict, because this is the natural property of wood.
