Molded Products

Redco FRP Grating provides durability with extremely high strength and stiffness. Due to its high load capacity it can be used with confidence in structures where high load and wide support spans are required. Redco FRP Grating is also lightweight (80% lighter than steel), corrosion resistant, and non-conductive making it ideal for applications where electrical current or chemicals may be present. Redco FRP Grating is low maintenance and has a low cost of installation.

Type VEFR-25 is a premium vinyl ester resin with a flame spread rating of 25 or less. Type VEFR-25 resin provides the most chemical resistance in the industry, designed to withstand the harshest chemical environments over a broad range of acids and caustics, it is primarily used in petrochemical, waste water, mining,and plating applications where the grating is subject to frequent and direct contact with harsh chemicals.

Type VEFR-10 is manufactured with the same high-quality vinyl ester resin but with an enhanced flame spread rating of 10 or less for those applications requiring more flame resistance, such as an offshore platform.

Type IFR-25 is a premium isophthalic polyester resin with a flame spread rating of 25 or less. Type IFR-25 provides an intermediate level of chemical resistance and is the correct resin choice for grating subjected to splash and spill contact with harsh chemicals, and is a very good general purpose resin at a reduced cost compared to the premium vinyl ester resin.

Type IFR-10 is the same high quality isophthalic polyester resin but with an enhanced flame spread rating of 10.

Type FG-30 is manufactured using a premium food grade polyester resin containing no harmful ingredients and is certified by the resin manufacturer. Each panel is post cured and detergent washed prior to shipment. This grating possesses a flame spread rating of 30.

Type CFR-25 is an orthophthalic polyester resin with a flame spread rating of 25 or less providing moderate chemical resistance. This grating is perfect for use in water/wastewater applications, light industrial applications, and in the wavezone areas of offshore platforms where the environment is moderate. Although Type CFR-25 is the least chemical resistant resin, it still offers superior performance to traditional flooring products such as steel, aluminum and wood, and is the most economical resin available.

Type O-AN is the same as type CFR-25 but non-fire retardant.

Type MP-5 is molded phenolic grating where fire resistance, low smoke, and low toxic fumes are critical. Tested in ASTM E-84, Type MP-5 resin has a flame spread rating of 5 and smoke density rating of 5. Our Type-5  molded phenolic grating is typically used in confined spaces, subways, offshore and other applications where fire resistance and low smoke generation is absolutely necessary.
