FRP grating is an open-mesh composite floor panel with a gritted anti-slip top, used instead of steel grating where steel rusts quickly: walkways, working platforms, trench covers and manhole covers in chemical plants, wastewater plants, ports and coastal sites.
Why replace steel grating with FRP grating?
Steel grating over wastewater tanks, chemical trenches or near the sea rusts fast, its edges thin out and it can fail under foot. FRP does not rust and does not conduct electricity, so it can be laid near electrical equipment and pipework. FRP panels are much lighter than steel; one or two people can lift a trench cover. The open mesh lets water and chemicals drain, and the gritted surface stays slip-resistant when wet.
How is the grating thickness chosen?
Thickness depends on the distance between the support beams and the load: pedestrians only, trolleys or forklifts. FRP is less stiff than steel, so for the same span and load an FRP grating is usually thicker than a steel one.
What do I send to order FRP grating?
Santiago FRP cuts the panels to your floor plan. Send the drawing or dimensions, the beam spacing, the type of traffic and the chemicals present, and we will advise the thickness and quote. Other FRP products: FRP stairs.
Frequently asked questions
What is FRP grating?
FRP grating is an open-mesh floor panel made of glass fibre reinforced polymer, with a gritted anti-slip surface. It does not rust or conduct electricity and replaces steel grating in wet, chemical or coastal areas.
Where is FRP grating used?
Walkways and platforms over wastewater tanks, trench and manhole covers in chemical plants and plating shops, jetty and port decks, and floors around electrical equipment.
What information is needed to order FRP grating?
The floor plan or dimensions, support beam spacing, type of traffic (pedestrian, trolley, forklift) and the chemicals in the area.
