The invention discloses a magnesium-aluminum alloy pedal tubular beam, which comprises a multi-curvature pipe body, wherein the top end of the multi-curvature pipe body is sleeved with a frame connecting plate, and a pipe body positioning piece is installed at the bottom end of the multi-curvature pipe body; the pipe body positioning piece comprises a lower seat body and an upper insertion pipe, an upper inserting pipe is vertically arranged on the surface of the lower seat body, the lower seat body is in a cuboid shape, a concave semi-arc matching surface is arranged on the bottom surface ofthe lower seat body, a supporting ring is vertically arranged on the outer wall of the bottom of the multi-curvature pipe body, a pressing ring is attached to the top surface of the supporting ring, the outer wall of the multi-curvature pipe body is sleeved with the pressing ring in a sliding mode, and the pressing ring is fixedly connected with the bottom pipe through a first locking screw. According to the invention, the multi-curvature pipe body and the bottom pipe can be connected into a whole from the middle through the pipe body positioning piece, the connection is easier and more convenient, the assembling efficiency is effectively improved, the matching effect at the connecting position is better, and conformal plasma cutting does not need to be conducted on the bottom end of the multi-curvature pipe body any more.
