Multilayer solid wood flooring (solid wood composite flooring) takes fast-growing wood as the base plate, such as poplar, elm and birch. These floorings are interlaced with horizontal and upright in each layer and shaped under the high temperature and hot pressure. This can greatly reduce the wood distortion probability. The flooring surface is decorated by the crude solid wood tegument. It is not only enjoying the solid wood, but also reducing the material cost and lumber waste and this is the new development orientation and trend of solid wood flooring. The base plate which has the particular quality of interlacement with horizontal and upright can perfectly stand against the distortion problem leaded by the flooring heating. And this is the best choice of the flooring heating.
