The present invention relates to a flange type corrugated steel plate. According to the present invention, the flange type corrugated steel plate has flanges in both sides of the flange type corrugated steel plate. In the corrugated steel plate, a corrugated part where a steel plate mountain part and a steel plate valley part are repeated in a short direction is lengthily formed in a long direction. A first hanging mountain part is formed in one end of the long direction of the corrugated part, and a second hanging mountain part is formed in the other end. Vertical through holes are respectively formed in the first hanging mountain part and the second hanging mountain part. Flanges having a horizontal through hole are combined to both sides of the short direction of the corrugated part. A concave step is formed in one side combined to the first hanging mountain part, and a convex step is formed in the other side combined to the second hanging mountain part. |
