The utility model relates to a container with reinforced side walls. Aiming at solving the problem that the side walls of the present container can be easily damaged when being impacted because the strength of the lower part of the side walls is not high enough, the utility model provides a container with reinforced side walls. The utility model has the technical proposal that the height of the upper rim of the bottom side beam is increased to be within 180 to 345 mm, since the thickness of the upper rim of the bottom side beam is larger, larger impact can be endured, under the condition that the weight of the container body is ensured not to be increased greatly, the strength of the lower half part of the side walls of the container body is enhanced, and then the probability that the lower part of the side walls of the container body is cracked during moving, carrying and piling up the containers can be reduced.
