A reinforcement H-beam is provided to have a cross-sectional structure for minimizing an increase in the cost and obtaining high bending strength. A reinforcement H-beam includes a reinforcement unit(100) projected to the outside of a flange(11), wherein the reinforcement unit is formed to be the most projected outward at the central part and less projected gradually at two sides of the central part, and a reinforcement member is coupled with the flange and provided with a joint extended to two sides of a curved surface and a coupler coupling through a coupling hole formed in the deep part of the flange and a coupling hole formed in the deep part of the joint of the reinforcement member, and a hollow is formed between the reinforcement unit and the flange.
