Moulded Gratings

Moulded FRP gratings are manufactured by casting glass fibers and resin in a mold to form a single-piece panel. This yields bi-directional strength (equal in X and Y directions) and a smooth, uniform appearance. These panels inherently come in a square/rectangular mesh pattern and can be produced with several surface textures. During molding, the mixture of continuous fiberglass rovings and high resin (typically ~65% by volume) creates very chemical- and corrosion-resistant panels. As a result, moulded grating is often chosen for highly caustic or wet environments where safety is paramount. Moulded FRP gratings (as above) offer exceptional load-carrying capacity in all directions. Their manufacturing process yields high uniformity and durability: panels won’t delaminate or rust, and they resist UV and fire (standard panels meet ASTM E84 Class 1). Custom panels can include fire-retardant or anti-static resins. All panels can be drilled or cut on site with standard tools.

Key Features

  • One-piece construction (no directional bias); customizable mesh and support patterns; variety of resin systems (polyester, vinylester, fire-retardant phenolic); UL94 V0 or Class A options; ASTM-tested slip resistance surfaces.

Benefits

  • Outstanding corrosion resistance (ideal for acids, alkalis, marine atmospheres); low maintenance (no corrosion, no painting); inherent slip resistance (concave “meniscus” profile or grit surfaces); fire safety (Class 1); impact and weather resistant. Minimal deflection under load and long service life.

Applications

  • Chemical spill containment grids, wastewater channels, industrial flooring, catwalks, stair treads, trench covers, pool gratings, platforms, and any application requiring safety grating. Also used in architectural floors and waterfront docks.

Technical Specifications

  • Standard sizes (e.g. 3′×10′, 4′×8′, 4′×12′) and thicknesses (20–50mm). Typical rib spacing 38×38mm; fiber content ~32% (E-glass). Panel weight ranges ~12.5–19.0 kg/m² depending on thickness. Panel flatness within ±2mm. Meets ASTM C 1028 (slip), UL94 V0, and European DIN/ISO standards as required.

Unique Selling Points (USPs)

  • Moulded grating panels allow large cutouts (up to 10″) without reinforcement due to their bi-directional strength. Available in very high corrosion-resistant resins (vinyl ester, epoxy) and specialty coatings for extreme environments. Panels can be colored or translucent for aesthetics.
