Fiberglass Grating

FIBERGLASS

Molded

Russels offers two types of quality fiberglass grating, molded and pultruded. Both types are lightweight and easy to install. Molded grating is unmatched in its ability to withstand the effects of corrosion and is highly impact resistant. Pultruded grating provides reliable corrosion resistance and high load bearing characteristics.
Fiberglass grating weighs less than half that of steel, is simple to fabricate and is less expensive to install.
FRP grating exceeds the requirements for grating used in even the most demanding applications. In industries such as chemical, refining, offshore, pulp and paper, food and beverage, marine (including military vessels), water and wastewater treatment, electronics and plating, Fibergrate grating is proven to deliver years of reliable service.

Pultruded

To specify your FRP Grating choose:
(1) Molded/Pultruded
(2) Resin system
(3) Grating thickness
(4) Mesh Pattern
(5) Panel sizes needed
(6) Grit or concave top

Pultruded Grating

sec 12 barsx safety and fiberglass grating page 48 img 01

Safe-T-Span ® and Safe-T-Walk ™ pultruded gratings deliver proven performance and economy. Fibergrate’s pultruded gratings combine durability and corrosion resistance with extremely high unidirectional strength and stiffness allowing their unrestricted use in applications requiring wide supports.
Using both a mechanical and chemical lock, Safe-T Span ® is manufactured with a flush-top tie bar configuration which increases the panel’s support and stability under load. A standard grit-top surface provides sure footing. Safe-T-Span’s protective synthetic veil, covering the exterior surface of the load bearing bars, allows it to reliably withstand constant exposure to ultraviolet rays.

Safe-T-Walk ™ grating is your low cost solution for lightweight, maintenance free floor grating. Designed specifically for pedestrian walkways, Safe-T Walk grating can be the ideal solution in any application where a strong, durable, lightweight surface material is required. No other fiberglass grating can offer this unique combination of performance and competitive price.

SAFE-T-SPAN/SAFE-T- WALK GRATING RESIN SYSTEMS

• ISOFR – This isophthalic polyester resin formulation provides a low flame spread rating of 25 or less and is designed for applications where there is moderate exposure to corrosive elements.

• VEFR – With a flame spread of 25 or less, this vinyl ester resin system provides dependable resistance to both acidic and alkaline environments.

* Standard colours are yellow and gray.

NOTES:

1. FIBERGRATE’S LOAD/DEFLECTION TABLE FOR MOLDED GRATING USES 8 LOAD BARS/FT OF WIDTH FOR UNIFORM AND CONCENTRATED LOAD TYPES. SOME MANUFACTURES USE 9 LOAD BARS/FT, WHICH OVERSTATES GRATING PERFORMANCE BY AS MUCH AS 12.5%, WHEN COMPARING FIBERGRATE’S TABLES TO 9 BAR TABLES, MULTIPLY FIBERGRATE’S REPORTED DEFLECTIONS BY 0.89.

2. ULTIMATE CAPACITY represents a complete and total failure of the grating. Values are provided to illustrate the reserve strength of the grating at a given span and are NOT to be used for design. Functionality of grating is limited to MAX RECOMMENDED LOAD.

IMPORTANT:

Installation should provide for fully supported abutments of grating panels. Otherwise, higher deflection values may be experienced, and tripping hazards may occur.

Stub bars should not exceed 3” in length at any time on 6” tie bars nor 6” at any time on 12” tie bars.

Stub bars should not be less than 1” in clip attachment areas.

Safe-T-Walkload bars at platform edges should be fully supported.
