FRP Floor Grate Fabrication

FRP Floor Grates have qualities that make installation in the field easier than steel, but there are also some extra considerations to be aware of.

FRP Floor Grating is Lightweight

The light nature of the floor grating panels makes installation much simpler, without the need for heavy machinery. Make sure to wear gloves and safety goggles, and a respirator mask while cutting, so dust particles aren't breathed in.

Fabricating & Cutting

FRP Floor grates can be cut with regular carpenter's tools like a sabre saw or circular saw. For large jobs, we recommend using diamond grit blades, or tungsten carbide grit-edged blades. This ensures accuracy and withstands prolonged use.

All cutting should be done in well ventilated areas, and with proper safety equipment (e.g. eye protection). Mark the grating with a pencil and a straight edge. After the floor grate has been cut, make sure to seal all the cut edges with a similar resin to the grating. This ensures that all elements are fully corrosion resistant.

Both pultruded and molded fiberglass floor grates can be fabricated in a similar way.

Installing Hold-Down Clips

The most common clip provided is an M-Clip made of Stainless Steel. A general rule of thumb is to use one clip for every four square feet of grating. This is true whether the floor grate is kept whole or cut for a narrow long stretch, like 2' x 40'.

Clips prevent the floor grate from shifting over time. Typical clips have the main fastener, a hex bolt, nut, and washer.

Supporting the Floor Grates

Ensure floor grate has proper support. Read the load tables to see how far apart the supports need to be. For cut-out areas, like circles, it is recommended to use support bars to ensure the floor grating bearing bar ends are secure. If it is not possible, use hold-down support bars on each side of the cut-out hole.
