Pandadeck® High-Strength (HS) Pultruded Fiberglass Grating provides maximum stiffness and minimum deflection over long spans. They are ideal choice to substitute steel and aluminum gratings in corrosive environments. The pultrusion process permits production of continuous bars lengths in up to 20 feet (longer upon request), then these I or T bars are mechanically interlocked and bonded by either two-parts or three-parts cross-rod system to resist torsion, bending or loading.
