A fire-resistant fiber ply board which is consisted of 50% coconut shell fiber strings, 25% mineral powder, 25% urea gel mixture. This mixture is poured into an extrusion die, adding blocks of certain thickness at the four corners, then covering with a board and adding pressure so that the mixture material is pressed and contracted to the height of the thickness blocks so that the mixture material of each layer is tightly sealed as layered boards providing fire-resistance property and which can be sawed, nailed fiber ply board construction.
