The wood flooring and its production manner of the symmetrical structure which applies the wood which was heat-treated

摘要

Provided is wood flooring having a symmetric structure comprising application of carbonized solid wood to top and bottom layers and a process for preparing the same. The wood flooring of the present invention has a symmetric structure by symmetric lamination of high-temperature heat-treated veneers having a thickness of more than 2 mm on top and bottom layers and integration of the layers under given temperature and pressure conditions. Therefore, the wood flooring is capable of maintaining the balance, is capable of completely solving a problem of deformation due to environmental fluctuations, is capable of achieving dimensional stability and high-quality color of product, and is capable of removing surface contamination, thus making it possible to use contaminated lower-grade coniferous lumber as a wood flooring material.
