Pultruded FRP Grating — One Direction, Maximum Span
Unidirectional pultruded strength is engineered for the spans and loads molded grating cannot reach.
Pultruded FRP Bar Grating
I-bar profiles deliver the highest strength-to-weight ratio for long spans and heavy loads.

T-bar adds lateral stability; square bar adds stiffness with a lighter panel.
View range →Molded FRP Grating
Bi-directional molded fiberglass grating for platforms, walkways and covers.

Frequently Asked Questions
Pultruded FRP grating — also called pultruded fiberglass grating, pultruded GRP grating or FRP pultruded bar grating — is made by continuous pultrusion of glass fibre rovings and resin into load-bearing bar profiles, assembled into open-mesh panels for long-span, high-load applications.
Pultruded FRP grating has unidirectional strength along the bearing bars: it spans further and carries heavier concentrated loads than molded grating. Molded grating has equal strength in both directions. Use pultruded for long spans, pipe racks and heavy equipment access; molded for platforms and trench covers.
Pultruded FRP I-bar grating, T-bar grating and square bar grating, plus pultruded FRP grating panel and pultruded FRP grid panel formats with open mesh, grit top, smooth and concave anti-slip surfaces.
Span depends on profile depth and load class. Large span pultruded FRP grating and high load pultruded FRP grating are engineered per certified load/span charts supplied with every quotation — spans commonly exceed 3 m with I-series profiles.
Standard pultruded FRP grating: 7-15 days production; custom pultruded FRP grating and cut to size fabrication 15-20 days, plus shipping. Urgent and export orders can be prioritized.
