PROBLEM TO BE SOLVED: To provide an inexpensive skid for a walking beam type heating furnace having excellent durability. SOLUTION: The skid 1 comprises a skid pipe 3, a plurality of skid buttons 2 protruded on an upper part of the skid pipe 3 to support a steel member, and monolithic refractory 5 to cover the skid pipe 3. A plurality of protective plates 7 are protruded in a flange shape from the monolithic refractory 5 with intervals in the longitudinal direction of the skid pipe 3 and erected on the skid pipe 3. When the steel member is lifted by the movable skid and the steel member with its tip bent downwardly falls, the tip is received by the protective plates 7 to prevent damages of the monolithic refractory 5 caused by the collision of the steel member.
