The invention relates to improvement of a rolling type fabricated stairway structure, in particular to a rolling type fabricated stairway which has good toughness, durability and erosion resistance. The rolling type fabricated stairway comprises an oblique beam, a bracket is arranged on the oblique beam, and step boards are fixed on the bracket. The rolling type fabricated stairway is structurally characterized in that the step boards made of PPECC (polypropylene engineered cementitious composite) are adopted.
