Pultruded Grating

The Pultrusion Process for Grating

Supergrate® pultruded grating is a high-strength lightweight fiberglass grating system. CCG fabricates this grating system 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. During this process, resin, roving, mat and surface veil are guided into a heated die to make a constant cross-section. A synthetic surface veil is also added to provide a resin-rich surface for corrosion resistance and UV protection.

SUPERGRATE® Pultruded Grating

This fabricated grating is exceptionally stiff and has a modulus of elasticity of over 5 Msi. The 65,000 psi bending strength means that this grating is built for durability. A combination of strength and stiffness gives Supergrate® these attributes which 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 standard molded FRP grating systems.
