Pultruded Fiberglass Grating

Kenway Composites provides pultruded fiberglass grating through Creative Pultrusions.


Supergrate® Pultruded Grating

Supergrate® Pultruded Grating is a high strength lightweight fiberglass grating system fabricated from highly corrosion resistant I or T bars. The I or T bars are connected mechanically and adhesively with a unique notch and groove bar system. The pultrusion process is a continuous process where resin, roving, matt and surface veil are guided into a heated die to make a constant cross-section. The synthetic surface veil provides a resin rich surface for corrosion resistance and UV protection.

The fabricated grating is exceptionally stiff boasting modulus of elasticity of over 5 Msi. The 65,000 psi bending strength means that this grating is built for durability. The combination of strength and stiffness give the Supergrate®attributes that are ideal for industrial flooring applications in which impact strength and toughness are daily requirements.

Supergrate® Pultruded Grating can achieve longer spans and higher load capacity than the standard molded FRP grating system. Learn More!
