The invention discloses a container steel floor and a container with the same. The container steel floor is arranged on a bottom support of the container and used for bearing cargoes, a plurality of blind waves upwards protruding out of the container steel floor are arranged on the container steel floor in parallel, each blind wave comprises a first edge and a second edge, wherein the length of the first edge is larger than the length of the second edge, and the blind waves are arranged in the length direction of the container; and parts, between the second edges of the blind waves and the edges of the container steel floor, of the container steel floor are of arc-shaped structures, and the height of the parts, upwards protruding out of the container steel floor, of the arc-shaped structures is smaller than the height of the parts, upwards protruding out of the container steel floor, of the blind waves. The container rigid floor is provided with the multiple blind waves in parallel, the strength can be increased, and assembly deformation is reduced. As the edge parts in the length direction of the container rigid floor are connected with the blind waves through wavy connecting plates, the structure of the edges of the container rigid floor and the bottom support of the container can be automatically and continuously welded.
