Abstract: A molded grating includes at least a grating member and a grating connector. The grating member includes a plurality of grating walls, each having a predetermined height, spaced apart with each other, and a plurality of crossing walls integrally connected to the grating walls in a cross manner, wherein each of the grating walls has an enlarged end portion and an elongated grating body extended therefrom, so as to enhance a structural strength of the grating member. The grating connector includes two resilient wings each having a wing cavity shaped and sized to receive the respective enlarged end portion of the two grating walls to substantially engage the resilient wings with the two grating walls respectively, so as to detachably attach the grating connector to the grating member.
