Fiberglass Grating Pultrusions come in three categories: I-Shape bars, T-Shape bars, and High-Load bars for Heavy-Duty Applications. The bearing bars are interconnected with cross-rods. Panels are mechanically assembled and chemically bonded and assure a high corrosion resistance together with an excellent mechanical strength thanks to the high percentage of glass fibers (roving, continuous multidirectional mat, veil). FRP Grate Benefits: Corrosion resistant. High strength-to-weight ratio. Long service life. Fire retardant. Slip & impact resistant. Non-conductive. Superior ergonomics. Easy to fabricate. Easy to install.
