I-Beam Pultruded Grating

FRP I-Beam grating panels have parallel I-beam bearing bars (typically 25–38mm deep) with molded or pultruded rods interwoven, creating a strong, rigid panel. They are ideal where very high strength and stiffness are needed (e.g. long-span platforms). The I-beam design uses more glass fiber in the bearing bars for excellent bending resistance.

Key Features

  • High longitudinal strength; lightweight; skid-resistant fiberglass top finish; resin choice for chemical resistance; standard sizes up to 4′×20′.

Benefits

  • Withstands heavy point loads and forklift traffic; resists impact and abrasion; fire retardant options available; low deflection under load. Reduces downtime and replacement costs compared to steel (which rusts) or concrete.

Applications

  • Oil & gas platforms, power plant catwalks, coastal/marine structures, pulp/paper mill floors, off-shore walkways, mining facilities.

Technical Specifications

  • Bearing bars depths 25mm (1″) or 38mm (1.5″); cross-rod spacing (typically 38×38mm pitch); available in polyester or vinylester resin. Panels may be fabricated from 60k or 80k fiberglass roving.

Unique Selling Points (USPs)

  • Can be custom-fabricated to any shape or size; standard resin systems achieve ASTM Class 1 fire rating; non-sparking for industrial safety; 25–80% lighter than steel equivalent, saving on structural support and installation.
