Liquid resin and continuous fiberglass roving are systematically laid in the mold, layer after layer
manually, to produce the desired thickness and panel dimensions. The finished molds are set aside for
a predetermined time to allow the panel to cure. The panel is then ejected from the mold. The molds are
cleaned and prepared for the process to begin again.
The one-piece interwoven square mesh construction of molded grating produces two primary
benefits: maximum corrosion resistance and high strength. Because the grating is “cast” in one piece, there is no
mechanical joint between bearing bars. The high percentage of resin in molded grating offers superior
corrosion resistance. The molded grating with a square mesh pattern offers increased load capacity and panel
utilization due to this bi-directional trait.
Cutting access holes in the molded grating does not weaken the panel and does not require additional or costly supports.

The design procedures associated with Composite Grating are entirely different from those
associated with other materials. The prime consideration in designing with this reinforcement is
allowable ‘deflection’ as opposed to ultimate ‘loading’ used with steel and aluminum. The reason
for this is the inherent elasticity of reinforced plastic, permitting far greater deflection than steel,
without the danger of structural failure. Load and deflection tables are available on request
Composite Grating’s integral grit top surface provides outstanding anti-slip protection for personnel
in wet and oily environments. The grit is embedded in the top surface of each panel before curing.
This combination of integral construction, plus the depth of the embedded grit, creates a long-lasting
the maximum anti-slip top surface.
Over a wide PH range (both acidic and caustic) is achieved by the use of a premium-grade resin system.
FRP grating will outperform metallic grating when exposed to continuous submersion, splashing,
spills, fumes, or gases. Corrosion is a significant problem for metal grating, stair treads, and other products
in many different industries such as chemical plants, food and beverage factories, water and
wastewater facilities, power facilities. Molded grating is particularly designed to provide safe, long-lasting and economical, and worry-free solutions environments where chemicals and other corrosive
materials attack and destroy metal.
Composite Grating is available in various resin systems, two of which meet the Class 1 flame spread
rating of 25 or less, in accordance with the ASTM E-84 Tunnel Test Method. If a flame spread of 10 or
less is required, it will be available at request.
The non-magnetic properties allow the Composite grating to be used in sensitive installations where
the inherent magnetic properties of metallic grating would prove unsuitable.
The impact resistance of Composite Grating allows repeated deflection without permanent
deformation. A certain amount of deflection can occur with loading. However, once the load is
removed, the grating will return to its original shape, unlike metallic grating, which will remain
deformed and require costly repairs or replacement.
