A molding steel sheet assembly beam is provided to make the adjustment of lateral surface height possible and to gain an excellent productivity since the molding steel sheet in not manufactured in the factory. A molding steel sheet assembly beam comprises a base part(111,121), a side perpendicular part(112,122) curved upward from the one-side end of base part, a support part(113,123) which is curve-cut in the top of the side perpendicular part, a first molding steel sheet(110) which is shaped from the other side end of base part in order to have center vertical parts(114,124) curved upward, a base part, a side perpendicular part curved upward from the one-side end of base part, a support part which is curve-cut on the top of the side perpendicular part, a center vertical part curved upward from the other side end of base part, a second molding steel sheet(120) which is shaped in order to have the part of upper flange(125).
