This grating is manufactured by pulling fiberglass strands through a resin bath and into a heated die where it is formed and cured.
The completed parts are then assembled into finished grating using both a mechanical and a chemical lock. Grit top anti-skid surface is standard.
D.E.F.I.’s pultruded grating provides the capability to support heavier loads and longer spans when compared to molded grating of similar depth and weight. D.E.F.I. has an extensive offering of pultruded gratings to meet most every need from ADA compliant walkways to heavy duty vehicular traffic conditions. D.E.F.I.’s pultruded gratings are engineered to withstand corrosive conditions that also require high strength.
Standard Resin Systems
D.E.F.I.’s pultruded grating is available in two standard resin systems each providing differing levels of corrosion protection. Both resin systems meet Class 1 Flame Spread Rating per ASTM E-84 test standards.
|IFR: a premium grade Isophthalic Polyester Resin System that provides excellent corrosion protection. Standard colors available: Yellow and Dark Gray||VFR: a Vinyl Ester Resin System provides the highest level of corrosion protection. Standard colors available: Yellow and Dark Gray|
