The pair of bottom side rails are located at both sides of the bottom of the container respectively. The plurality of cross members are located between and connected to the bottom side rails. The floor is laid on the cross members and extends along the longitudinal direction of the container; the floor comprises a first steel floor. The bottom frame further includes a grit discharging structure configured to discharge the grits, collected on the upper surface of the first steel floor after the inner surface and/or the welding seam on the inner surface of the container is shot-blasted, from the container. The container according to the present disclosure could allow for discharging the sand collected on the upper surface of the first steel floor after shot-blasting the inner surface and/or the welding seam on the inner surface of the container, thus facilitating the shot-blasting.
