Abstract: PURPOSE: A wooden deck production method using dual compression and a carbonization process and a wooden deck produced thereby are provided to prevent deformation or distortion caused by contraction and expansion followed by environmental change as size stability is superb by removing a hydroxyl group left in a wood while overall density is even as a density deviation is minimized. CONSTITUTION: A wooden deck production method using dual compression and a carbonization process includes the following stages; (1) a processing stage (S100) which makes woods which are cut pass through a compressing roller after cutting a hardwood in a long form; (2) a drying stage (S200) which dries the processed wood putting into a drying chamber; (3) an immersing stage (S300) which immerses the dried wood into a solution composed of adhesives and additives; (4) a production stage (S400) which produces a first compressed wood by compressing the immersed wood with an extra-high voltage press machine after putting the immersed wood into a mold frame; (5) a maturing stage (S500) which puts the first compressed wood into a maturing furnace in a state which the compressed wood is placed in the mold frame; (6) a production stage (S600) which produces veneers by cutting the first compressed wood which is matured after separating the first compressed wood from the mold frame; (7) a laminating stage (S700) which laminates the veneers on a mold frame by applying the adhesive; (8) a production stage (S800) which produces a second compressed wood by compression the laminated veneer through the press machine; (9) and an oil carbonization stage (S900) which removes a hydroxyl group remained in the second compressed wood by heating after putting the second compressed wood into an oil tank.
