A double-sided plastic pallet is provided to prevent initial breakage or wear and to exchange only a broken part by substituting a double metal structure for thin portions of the upper and lower parts and combining/separating the double metal structure with/from a pallet body. Upper and lower parts of a double-sided plastic pallet(4) are symmetrically cut into four parts in a staple form from the outline of the front and rear sides to the inner middle portion. The upper and lower parts formed at the left and right sides of a staple-shaped cut part are stepped. Partial upper and lower surfaces(1,2) that are a double metal plate of an uneven structure and the flat plate are placed on the plane of the stepped part. Long hexahedral fixing units(7) are placed on the left and right stepped parts of the partial upper and lower surfaces to firmly fix the partial upper and lower surfaces to the stepped plane of the plastic pallet. Plural circular grooves(6) are biased toward a thickness part on the upper and lower surfaces of the long hexahedral fixing units correspondently to each fixing position of bolts. Long bolts(3) are fitted to circular holes bored through each center of the circular grooves and nuts(10) are joined to the opposite side.
