A flooring material of a symmetrical structure using heat-treated timber is provided to keep balance, to solve the transformation problem caused by environmental changes perfectly, and to improve dimensional stability compared with the existing wood floor by having the excellent rate of change by moisture and heat. A flooring material is formed in a symmetrical structure by piling up heat-treated timber layers on the upper and lower parts of a base layer, wherein the heat-treated timber layer is a single plate heat-treated at the temperature of 230~150°C, the upper heat-treated timber layer is a wood floor having a thickness of 2mm and more, and the base layer is composed of one or more kinds of wood-based boards selected among material wood, waterproof plywood, MDF(Medium Density Fiberboard), HDF(High Density Fiberboard), a particle board, and a resin wood powder composite board. |
