Pultruded Gratings

Fiberglass pultruded gratings are high-strength, corrosion-resistant panels made by pultruding continuous glass fiber rods and resin into I-beams or flat bars. They offer exceptional durability and a light weight versus metal alternatives, with each panel tailored for heavy-duty use. Pultruded gratings are non-conductive, rust-proof, and UV-stable, making them ideal for harsh or electrically sensitive environments. They require minimal upkeep, and installation costs often rival steel once long-term benefits are considered. These systems meet stringent industry standards for load and fire performance, and are commonly certified to UL or ASTM specifications for flame spread.

Key Features

  • Continuous I-beam or flat-bar construction; high fiber-to-resin ratio; Class 1 fire rating (ASTM E84) options; ANSI or OSHA compliant profiles.

Benefits

  • Extremely lightweight (up to 80% lighter than steel) yet high-strength; corrosion and chemical resistance for decades of service; low-maintenance (no painting/rusting); non-conductive for safety in electrical or marine applications.

Applications

  • Factory floors, catwalks, stair treads, platforms, bridges, trench covers, pool grates, acid or chemical plants, wastewater facilities, and any corrosive environment.

Technical Specifications

  • Standard panel widths (e.g. 3′×20′, 4′×20′) and depths (1″/25mm, 1.5″/38mm). Custom profiles available; typical load tables match or exceed equivalent steel. Resins include polyester or vinyl ester (Class 1 flame spread).

Unique Selling Points (USPs)

  • Engineered for heavy loads and wide spans while remaining easy to cut and bolt together; recessed tie-bar design for a flush top surface; can be color-coded (yellow, gray, green) for safety; competitive installed cost with steel due to lower labor and maintenance.
