FRP SMC Gully Gratings & Trench Covers For Stormwater Drainage

Material for Gratings: FRP or GRP SMC

Load Class: From A15 to F900

FRP Gully Grating

Fabricated from premium resin and fiberglass materials, FRP gully gratings feature light weight, exceptional durability and superior corrosion resistance.

Specially engineered to shield and cover drainage inlets, they facilitate unobstructed water drainage and maintain stable long-term performance amid severe working environments.

Applicable to municipal stormwater drainage as well as heavy-duty industrial drainage systems, these gratings possess robust structural strength and require virtually no routine maintenance.

Each FRP gully cover is resistant to rust, chemical erosion and natural ageing, serving as an optimal substitute for conventional metal gratings.

Eco-friendly and conducive to sustainable infrastructure construction, our FRP gully gratings provide secure, high-efficiency and environmentally responsible drainage solutions for modern urban construction and industrial scenarios.

Application Scenarios
