Pultruded fiberglass grating is a fiberglass (frp) structural shape that is produced by dipping fiberglass such as strand, mat and veil in a liquid resin bath and then pulling this combination through a heated die which shapes and cures the composite before it comes out the other end. It is a continuous and highly efficient method of producing a standard cross section. A pultruded frpg is a series of i or t shaped structural members (the bearing bars) that are mechanically strung together with evenly placed dowels or cross bars. This is similar to the way many steel and aluminum gratings are assembled. The pultrusion is produced by dipping fiberglass such as strand, mat and veil in a liquid resin bath and then pulling this combination through a heated die which shapes and cures the composite before it comes out the other end. The cross bars often are slotted to provide some mechanical strength and the holes are then coated with epoxy. It is a continuous and highly efficient method of producing a standard cross section. As a result of this system's construction, this can be assembled in various panel sizes and with multiple cross rod and bar spacing to provide for different requirements. The main benefit of the pultruded type is higher glass content which provides for a superior load capacity than it's molded counterpart.
