Abstract
A grating of fiber reinforced plastic comprising a plurality of main beams of substantially I-shape in section made of fiber reinforced plastic and arranged in parallel to one another, and grid members also made of fiber reinforced plastic and engaged with the plurality of main beams to be integrally fixed to one another. By such a construction, there is produced an a cooperation between the high strength of the main beams and the load transmission performance of the grid members resulting in higher strength than conventional gratings of the same material. Individual components of the grating are suited for standardization and mass production, and besides gratings of various length and width are achieved by variation in the combination of the components.
