CORVEX®(Fibergrate only):
An economical polyester grating, Corvex outperforms a number of competitive fiberglass and metal products and meets the requirements for corrosion resistance found in light industrial and water/wastewater application. Color: yellow, dark gray or dark green. Flame Spread: ASTM rating of 25 or less.

CP-84(Chemgrate only):
A premium grade polyester resin, CP-84 offers excellent corrosion resistance in highly acidic conditions. This non-fire retardant resin is a chemical grade thermoset that has USDA acceptance for use in food processing plants. Color: green. Flame Spread: non-fire retardant.

ELS(Fibergrate only):
The added benefit of greater worker visibility and lower toxicity in emergencies, make ELS products ideal for tunnel, offshore, ship and other confined area application. Color: light gray. Flame Spread: ASTM rating of 15, a smoke density index of 70 and Fuel Contribution of 0.

FGI(Fibergrate only):
This isophthalic polyester resin system meets the unique requirements of the food and beverage industry. Color: light gray or dark green. Flame Spread: ASTM rating of 20 or less.

FS-25(Chemgrate only):
FS-25 is a polyester resin system designed for applications where there is moderate exposure to corrosive elements. This resin system is USDA accepted. Color: light gray. Flame Spread: ASTM rating of 25 or less.

IFR(Fibergrate only):
This isophthalic polyester resin formulation is designed for industrial and chemical processing applications where corrosion resistance is important. Color: green or dark gray. Flame Spread: ASTM rating of 20 or less. IFR is also available in a UL Classified resin formulation.

Super ViCorr®(Fibergrate only):
A superior grade vinyl ester resin system designed for extreme temperatures (180º to 400º F) and extremely corrosive environments such as solvents and acidic oxidizers, including aqueous chlorine and chlorine dioxide solutions forming sodium hypochlorite. This custom resin system is used mainly as packing hold-downs (bed limiters) and as packing supports in environmental or process scrubber and stripping applications. Color: natural - tan to beige. Flame Spread: non-fire retardant,
unless specified.

Vi-Corr®(Fibergrate only):

A superior vinyl ester resin available only from Fibergrate, Vi-Corr was developed for reliable performance in the toughest environments.It offers outstanding resistance to a wide range of highly corrosive situations, ranging from caustic to acidic. In fact, no other resin system can match Vi-Corr’s performance in highly acidic environments. Color: orange or dark gray. Flame Spread: ASTM rating of 15 or less. Vi-Corr is also available in a UL Classified resin formulation.

VE-25(Chemgrate only):
A premium vinyl ester resin system formulated to resist the highly corrosive properties of acids and caustics found in the harshest chemical environment. It is an economical alternative to the more expensive exotic materials often specified for highly corrosive conditions. Color: orange or dark gray. Flame spread: ASTM rating of 15 or less. This superior resin system will maintain its structural integrity at elevated temperatures of up to 180ºF.

XFR(Fibergrate only):
This highly corrosion resistant vinyl ester resin is recommended for use where the fire potential is high. Color: dark gray. Flame Spread: ASTM rating of 10 or less, a level exceeded by no other resin system.
