COMPOSITE FLOOR MATERIAL CONSISTING OF EXTRUSION TYPE MATERIAL

摘要

The disclosure relates to a solution to the problem of distortion and deformation of the floor of a lightweight shipping container. Heretofore, relatively heavy loading of lightweight shipping containers has caused the floor thereof to deflect sufficiently to distort the side walls and end walls of the container and often permanently deform the floor. In practicing the present invention, the floor boards adjacent the side walls of the container are modified so as to increase the resistance thereof to shear loads and thus minimize deflection.
