FRP Pultruded Grating

Rooffit FRP Grating as compared with other floor materials like Metal, PVC or RCC, provides a series of benefits, unmatched superior impact resistance, while the strength-weight ratio is only one fourth of that of steel gratings.

Hence FRP gratings are easy to handle, cut and install and can be customized to customer’s requirements as per site condition, utility application and weathering conditions. Rooffit brand FRP Gratings is the ideals solution for corrosion problem faced in industrial environments. The FRP grating is non-conductive of electricity and non-magnetic, great appearance, ease of installation and Maintenance Free.

Types of Grating:

  • Molded Gratings
  • Pultruded Gratings

Features

  • Anti-skid top surface
  • Dimensional stability
  • Easy to handle, store and install.
  • Total elimination of maintenance cost.
  • Corrosion resistant and fire retardant.
  • Suitable for horizontal and vertical layouts.
  • Self extinguishable with high level of safety.
  • Excellent temperature and weathering properties
  • Light weight, long lasting and maintenance free
  • Excellent strength-weight ratio compare to steel
  • Minimal distortion and higher mechanical strength.
  • Excellent insulation properties with high impact strength
  • Excellent physical, mechanical/chemical and atmospheric resistance properties.

Applications

  • Flooring
  • Trench and Drain covers
  • Platforms and walkways
  • Electrical cable trays
  • Stairways, hand rails and ladders
  • Chemical pipelines carriage trays
  • FRP cross arms for electrical applications
  • All load bearing structures using FRP pipe, Angle, Channel and Girders.

Pultruded FRP Gratings: "Rooffit" Pultruded Gratings is specially fabricated for applications that call for high strength, excellent corrosion resistance, exposed to various weathering and industrial conditions. Since Fiberglass is the key Raw Material of FRP Gratings strength, the content of fiberglass roving's used is 55-60% of the total weight, which can guarantee very high strength over large span.

The Pultruded FRP Gratings is made by pulling thermoset resin together with continuous fiberglass roving's through a heated mold in desired profile and size with temperature control at different sections of the die to facilitate resin to cure. It is a continuous and highly efficient method of producing a standard cross section. A Pultruded Grating consists of I or T shaped structural members (The load Bearing Bars) that are mechanically strung together with evenly placed dowels or cross bars. As a result of this system's construction, this can be assembled in various panel sizes and with multiple cross rod and bar spacing to provide for different requirements. The main benefit of the Pultruded type is higher glass content which provides for superior load capacity.

So, Pultruded FRP gratings are manufactured by assembly of Pultruded I beams (Load Bearing Members) & Pultruded Cross Rods (Cross Locking Members). The average distance between the I Beams is 40 mm, whereas the distance between the cross rod varies as per the load requirement of the application as per table given below:-

Ease of Installation

Working with fiberglass is comparable to working with wood, with slight differences in cutting procedures. Rooffit's FRP Grating can be fabricated in the field by the end-user. We recommend on site fabrication to ensure accurate and timely installation.

Finishing

All cut surfaces should be coated with resin to prevent corrosion of fiberglass. Edge Seal Kit is available with polyester resin, catalyst, brush and stirrers for ease of coating. Be sure to seal all cut edges prior to installation.

Standard Installation Clearances

Provide a minimum of 1/2" support for all edges of a Rooffit's FRP Grating panel.
