A sliding board includes a board body made of a light material, and at least one reinforcing unit mounted in the board body to reinforce a structural strength of the board body and including a plurality of reinforcing bars which are connected serially to form the reinforcing unit. Thus, the reinforcing bars are connected with each other to assemble the reinforcing unit so that the length of the reinforcing unit is adjustable so as to fit the board body of different length.
