FRP Pultruded Gratings
SIEGRID® series pultruded grating uses pultruded "I" or "T" profiles as load-bearing parts, and special bar seating to connect through the rod, and through a certain assembly process to make the plate with gaps.
The surface of the pultruded grating is grooved and non-slip or glued with non-slip sand, and can be glued with diamond pattern plate or sand plate to close the grating according to the customer's requirements, which can be used to prevent small objects from falling, splashing, odor volatilization and other special occasions.
