The invention relates to a profile for an automobile rear bumper and a manufacturing method thereof, the profile comprises a body of a rectangular tube body structure and a reinforcing rib located in the middle of the body, and the section of the profile is of a structure shaped like a Chinese character'ri '; wherein the section of the reinforcing rib is triangular, and the bottom edge and the vertex angle of the triangle are connected with the inner walls of the two opposite sides in the body respectively. According to the invention, the reinforcing ribs are optimally designed, and the rolled section bar is combined with an online double-laser welding process, so that the stability of the product structure is ensured; due to the fact that the rear bumper rolling profile is good in quality and reasonable in process and structure, the material can be thinned under the same strength, and integration of light weight and functionalization is achieved.
