Trench Covers

FRP Trench Cover Plates are sturdy composite panels that safely span open trenches and pits. They are engineered as a “high-performance solution” that is lightweight, strong and corrosion-resistant. The panels (often 10–20 mm thick) can support pedestrians and light vehicles, depending on thickness. Fiberglass covers are ideal in industrial plants, parking areas, and wastewater facilities because they withstand oils, saltwater and chemicals. Anti-slip gritting can be added for safety. Unlike steel plates, FRP covers won’t rust and remain even under harsh chemical washdown.

Key Features

  • Fiberglass-resin composite plates; uniform color for 360° strength; optional gritted or patterned surface for traction; stainless-steel inserts or handles for lifting.

Benefits

  • High load-bearing capacity (handles foot and occasional vehicle traffic); impervious to moisture and chemicals (won’t corrode); very light for easy removal; electrical insulation (safe in electrical trenches).

Applications

  • Covers for cable trenches, maintenance pits, drainage channels; overhead machine trenches in factories; lift-off covers in petroleum or chemical plants; general floor hatch covers.

Technical Specifications

  • Available in standard widths (500–1000 mm) and lengths up to 4 m; cover plate modules often come in 2–5 m lengths. Load rating designs typically carry 1–5 kN point loads per ASTM D790 or EN 13706. FRP thickness from ~6 mm (for pedestrian) up to 15+ mm for heavy-duty.

Unique Selling Points (USPs)

  • FRP trench covers combine the strength of metal plates with a fraction of the weight. They resist slip and stain, and can be made with high-visibility stripes or safety colors (embedded UV pigments). Moreover, they are non-magnetic and electrically insulating, enhancing worker safety in utility applications.
